Which RATIONAL Combi Oven Accessories Are Essential for a Commercial Kitchen? A Complete Buying Guide

A RATIONAL combi oven is a valuable investment for a professional kitchen, but its versatility extends well beyond the oven itself. The right accessories can help chefs prepare everything from perfectly roasted meats and crisp vegetables to baked goods, grilled dishes and high-volume breakfast meals, all while making better use of existing equipment.

For Australian restaurants, cafés, hotels, pubs, clubs, caterers and institutional kitchens, choosing suitable RATIONAL combi oven accessories is about more than adding extra trays or racks. It involves understanding how different cooking surfaces, containers and specialised tools influence food quality, production capacity and daily kitchen operations.

Some accessories are everyday essentials, while others are designed for specific menu applications. A bakery may benefit most from perforated baking trays and enamelled containers, while a busy hotel kitchen might prioritise Multibakers, poultry roasting racks and stainless steel GN pans.

This guide explores the most useful RATIONAL accessories available through Sydney Commercial Kitchens (SCK), explains their practical applications and provides buying advice to help hospitality operators make informed decisions.

Why Are RATIONAL Combi Oven Accessories Important?

RATIONAL combi ovens combine convection heat, steam and controlled humidity to perform multiple cooking functions within one appliance. Their ability to roast, bake, steam, grill and regenerate food makes them suitable for a wide range of commercial foodservice operations.

However, cooking performance also depends on how food is positioned inside the oven and the surface used during preparation.

A solid roasting tray provides a stable cooking surface for vegetables and proteins, while a perforated tray allows greater airflow around suitable baked products. Specialised grilling accessories support direct contact browning, and vertical roasting racks help organise poultry and ribs for batch production.

Using the right accessories can support several practical benefits, including more consistent cooking results, improved portion control, easier food handling and better use of available oven capacity.

Some RATIONAL accessories feature the manufacturer's TriLax non-stick coating, which is designed to support food release, heat transfer and browning. These specialised surfaces can be particularly useful when preparing foods that would otherwise require additional handling or conventional pans.

For commercial kitchens, the goal is not to purchase every available accessory. It is to identify the equipment that supports frequently prepared dishes and improves the cooking processes that matter most.

Understanding RATIONAL Combi Ovens Before Choosing Accessories

Before selecting accessories, it helps to understand the RATIONAL oven they will be used with.

The two principal RATIONAL combi oven ranges are the iCombi Pro and iCombi Classic. Both combine steam and convection cooking, allowing operators to prepare a broad range of menu items using one appliance.

The iCombi Pro offers advanced intelligent cooking assistance through technologies such as iCookingSuite and iProductionManager. These functions help manage cooking processes and organise production, making the range particularly useful for kitchens preparing varied menus or managing demanding service periods.

The iCombi Classic provides professional combi cooking capabilities with more direct operator control. It can suit kitchens with established recipes, experienced staff and straightforward production requirements.

Both ranges are available in different capacities, including compact models and larger floor-standing configurations. The appropriate size depends on meal volume, available space and kitchen workflow.

Accessories must be selected according to the exact oven model, generation and GN tray configuration. Although some accessories are compatible across multiple RATIONAL ranges, operators should never assume that every tray, rack or specialised attachment fits every oven.

Sydney Commercial Kitchens supplies RATIONAL commercial combi ovens alongside a range of cooking accessories, allowing businesses to consider the complete cooking setup when planning equipment purchases.

Which RATIONAL Combi Oven Accessories Are Most Useful?

The following accessories represent practical options for different commercial kitchen applications. Rather than listing every variation of similar products, this guide focuses on the main accessory types and their value in everyday food preparation.

1. RATIONAL Roasting and Baking Trays: Versatile Everyday Equipment

Roasting and baking trays are among the most frequently used accessories in commercial kitchens because they support numerous cooking applications without requiring specialised equipment for every dish.

The RATIONAL 6013-1103 Roasting and Baking Tray is a 1/1 GN accessory suitable for roasting vegetables, preparing proteins and baking selected menu items. Its design supports consistent cooking and makes it a practical choice for kitchens preparing different dishes throughout the day.

For foods that benefit from greater airflow, the RATIONAL 6015-1103 Perforated Roasting and Baking Tray provides an alternative. Its perforations allow circulating hot air to reach more of the food surface, supporting browning and crispness in suitable baked products.

This distinction matters for bakeries, cafés and restaurants where texture is an important part of food quality.

For example, a café may use a solid tray for roasted vegetables and a perforated tray for selected pastries or bread products. Having both options provides flexibility without unnecessarily increasing equipment complexity.

When choosing trays, operators should consider the required GN size, tray depth, expected loading weight and cleaning requirements.

2. RATIONAL Granite Enamelled Containers: Consistent Baking and Roasting

Granite enamelled baking containers are designed for dishes that benefit from effective heat transfer and a stable cooking surface.

They are particularly useful for tray pizzas, baked pasta, casseroles, cakes, slices and other foods prepared in consistent batches.

The RATIONAL 6014-1102 Granite Enamelled Baking Container, with a depth of 20 mm, is a practical example for relatively shallow baked products. Deeper versions are also available for dishes requiring additional volume.

The enamelled surface helps distribute heat across the container, supporting uniform cooking and browning. This can be valuable for businesses producing repeated batches where consistent results are important.

A bakery preparing slices throughout the day may benefit from using identical containers to standardise product thickness and portion sizes. Similarly, a catering kitchen preparing baked dishes in advance can use suitable containers to organise production.

The correct container depth should reflect the recipe rather than simply maximising food volume. Overfilled containers can affect cooking performance and handling safety.

3. RATIONAL Grill and Pizza Trays: Expanding Menu Possibilities

Grilling accessories allow commercial kitchens to prepare selected grilled foods using their existing combi oven.

The RATIONAL 60-70-943 Grill and Pizza Tray is a dual-purpose accessory designed to support pizza cooking and grilling applications. Its specialised cooking surfaces help transfer heat to food and support attractive browning.

Another option is the RATIONAL 6035-1017 CombiGrill Grill, which provides a traditional grill pattern for suitable meats, fish and vegetables.

These accessories can be particularly useful for cafés, restaurants and hotels preparing varied menus.

For example, a restaurant may use a grill tray for vegetables during lunch service and prepare grilled proteins later in the day. A café with limited cooking space may use a pizza tray to expand its menu without installing a separate pizza oven.

However, a combi oven does not necessarily reproduce the flavour of charcoal or open-flame grilling. Businesses specialising in flame-grilled food may still require a dedicated char grill.

The greatest benefit of these accessories is their ability to support additional cooking applications while making use of equipment already installed in the kitchen.

4. RATIONAL CombiFry Tray: Preparing Crispy Foods Without Conventional Deep Frying

Chips, wedges and crumbed foods are popular menu items in Australian pubs, clubs, takeaway businesses and casual dining restaurants.

The RATIONAL 6019-1150 CombiFry Tray is designed for preparing suitable pre-fried foods using circulating hot air inside a compatible combi oven.

Its specialised construction allows air to move around the food, supporting browning and crispness without immersing the products in additional frying oil.

For venues already operating a RATIONAL oven, this accessory can provide an alternative cooking method for selected convenience foods.

A pub preparing chips alongside roasted meats may find the CombiFry tray useful when managing different menu items during service. Catering businesses may also benefit when preparing pre-fried products in batches.

However, it is important to distinguish CombiFry cooking from conventional deep frying. Cooking times, textures and finished results depend on the food product, batch size and selected oven programme.

Operators should test their regular menu items before deciding whether the accessory can supplement or replace any existing frying process.

5. RATIONAL Multibaker: A Practical Solution for Breakfast Service

Breakfast preparation can be demanding when multiple orders require eggs, pancakes or individually portioned dishes.

The RATIONAL 60-71-157 Eight-Item Multibaker Tray is designed to prepare several portions simultaneously using a specialised non-stick cooking surface.

Its individual cooking positions can help staff prepare consistent portions without managing multiple conventional frying pans.

For hotels serving buffet breakfasts, the Multibaker may simplify the preparation of fried eggs and other suitable breakfast products. Cafés can also use it to support repeated orders during busy morning periods.

One advantage is consistency. When staff use the same cooking programme and portion sizes, the finished dishes can be easier to standardise.

The Multibaker is particularly relevant for kitchens where breakfast production is frequent enough to justify a dedicated accessory.

However, operators should consider actual peak demand and available oven capacity before purchasing.

6. RATIONAL Roasting and Baking Pans: Flexible Individual Cooking

Some dishes require a pan-style cooking surface rather than a conventional flat tray.

RATIONAL roasting and baking pans are designed for foods such as omelettes, pancakes, tortillas, rösti and selected baked dishes.

The RATIONAL 60-73-286 Small Roasting and Baking Pan Set includes four 16 cm pans, while larger options are available for different portion requirements.

These accessories can be useful for cafés, hotel kitchens and restaurants preparing individually portioned meals.

For example, a hotel may use smaller pans to prepare consistent breakfast dishes, while a restaurant may use them for individual baked desserts or speciality menu items.

Their stackable construction also supports more practical storage when the pans are not being used.

The value of these accessories depends on whether they match frequently prepared dishes and reduce unnecessary food handling.

7. RATIONAL Chicken and Duck Superspikes: Better Poultry Roasting

Whole roasted chicken and duck are popular in restaurants, takeaway businesses, hotels and catering operations. Preparing several birds simultaneously requires careful positioning to support even cooking and consistent browning.

RATIONAL Chicken and Duck Superspikes are designed to hold poultry vertically, allowing circulating hot air to reach more of the exposed surfaces.

The RATIONAL 6035-1016 Six-Spike Chicken and Duck Superspike is one example available through Sydney Commercial Kitchens. Other configurations accommodate different production requirements.

For venues regularly preparing roast chicken, these accessories can help establish a repeatable loading arrangement while making practical use of oven capacity.

Vertical roasting can also support more consistent presentation, which is important for businesses selling whole roasted birds.

Operators should select the appropriate configuration based on bird size, oven compatibility and required batch quantities. Correct core temperature monitoring remains essential for food safety.

8. RATIONAL Spare Rib and Potato Baker Racks: Practical Batch Cooking

Some foods benefit from specialised racks that position ingredients more efficiently inside the cooking chamber.

The RATIONAL 6035-1018 Spare Rib Grill Rack is designed to hold ribs vertically, helping kitchens organise larger quantities without laying every rack flat.

This can be particularly useful for pubs, clubs and barbecue restaurants preparing ribs in advance of service. Once cooked, the ribs can be finished with glazing or additional browning according to the venue's preferred method.

For baked potatoes, the RATIONAL 6035-1019 Potato Baker Rack provides a dedicated arrangement that supports airflow around the potatoes.

These accessories are useful when the same menu items are prepared frequently and in substantial quantities.

However, specialist racks are not essential for every kitchen. A venue preparing ribs only occasionally may find standard roasting equipment sufficient, while a business producing baked potatoes daily may benefit from a dedicated rack.

9. RATIONAL Stainless Steel GN Containers: Everyday Versatility

Stainless steel gastronorm containers remain essential in many professional kitchens because they support steaming, roasting, food preparation and batch cooking.

RATIONAL offers solid and perforated GN containers in different depths to accommodate a variety of foods.

Solid containers are suitable for preparations requiring food or liquid containment, while perforated containers allow steam circulation and moisture drainage.

For example, a hospital kitchen preparing steamed vegetables may benefit from perforated containers, while a restaurant preparing sauces or moist dishes may require solid pans.

These accessories are particularly relevant for schools, hospitals, aged care facilities, hotels and catering businesses where standardised container sizes simplify food production and handling.

Although less specialised than grilling or roasting accessories, suitable GN containers are often among the most frequently used items in a commercial combi oven.

10. RATIONAL VarioSmoker: Adding Another Cooking Technique

For restaurants interested in expanding their menus with smoked flavours, the RATIONAL 60-73-008 VarioSmoker provides an additional cooking application for compatible RATIONAL equipment.

It is designed to introduce smoky flavour to suitable foods, including meats, fish and vegetables.

This may appeal to restaurants offering smoked proteins, speciality dishes or contemporary menus that incorporate different cooking techniques.

For a kitchen already using a compatible combi oven, a smoking accessory may provide greater flexibility without immediately requiring a separate commercial smoker.

However, operators should confirm equipment compatibility, ventilation requirements and approved operating procedures before purchasing.

How Do You Choose the Right RATIONAL Accessories for Your Kitchen?

The most suitable accessories depend on the type of hospitality business, menu requirements and production volume.

For cafés and breakfast venues, Multibakers, roasting pans and general-purpose baking trays may offer the greatest practical value. Bakeries may prioritise perforated trays and granite enamelled containers, while restaurants preparing varied menus may benefit from grilling accessories and roasting equipment.

Pubs and clubs serving chips, ribs and roasted meats may find CombiFry trays and specialised roasting racks particularly useful.

Hotels, caterers and institutional kitchens often require a combination of GN containers, roasting trays and accessories that support organised batch production.

Before purchasing, operators should consider how frequently an accessory will be used, whether it suits their oven and how it fits into existing cooking procedures.

A versatile accessory used several times daily may provide greater value than a specialised product used only occasionally.

Can RATIONAL Accessories Help Improve Kitchen Efficiency and Reduce Costs?

Commercial kitchen efficiency depends on how effectively equipment supports everyday production.

The right RATIONAL accessories can help operators organise food preparation, maintain consistent portions and reduce unnecessary handling.

For example, a Multibaker may simplify breakfast production, while a spare rib rack can help organise larger cooking batches. Perforated baking trays may improve cooking results for suitable products, reducing the need for repeated adjustments.

However, accessories do not automatically reduce labour costs, energy consumption or food waste.

Their value depends on menu demand, cooking programmes, staff training, batch sizes and overall kitchen workflow.

Operators should evaluate whether an accessory improves a regularly performed task and whether the expected benefits justify its purchase price.

For businesses investing in a new RATIONAL oven, planning accessories alongside the main appliance can help establish a more practical cooking setup from the beginning.

Why Is RATIONAL Accessory Compatibility Important?

RATIONAL has produced several generations of commercial combi ovens, including the SelfCookingCenter, CombiMaster, iCombi Classic and iCombi Pro.

Although many accessories use standard GN dimensions, compatibility cannot be determined by tray size alone.

Specialised accessories may have additional requirements relating to cooking chamber clearance, loading arrangements or oven generation.

Before ordering, operators should confirm the exact oven model, accessory part number and manufacturer specifications.

This is particularly important when purchasing accessories for older equipment or replacing products that have been used for several years.

Sydney Commercial Kitchens offers a range of RATIONAL ovens and accessories, allowing buyers to explore suitable products and seek guidance before making a purchasing decision.

How Should RATIONAL Combi Oven Accessories Be Cleaned and Maintained?

Correct cleaning and maintenance help protect accessory surfaces, support food hygiene and extend useful service life.

Coated trays and specialised cooking surfaces should be cleaned using manufacturer-approved methods. Abrasive cleaning tools or unsuitable chemicals may damage non-stick coatings.

Stainless steel containers and grids may have different cleaning requirements from coated baking trays, flexible moulds or specialised roasting accessories.

Staff should inspect accessories regularly for damaged surfaces, deformation and signs of excessive wear.

Safe handling is equally important. Hot trays, containers and racks should be removed using appropriate protective equipment, particularly when handling heavy food loads.

A consistent maintenance routine helps preserve cooking performance and avoid unnecessary replacement costs.
