Convection and Grill Microwaves: How to Avoid Costly Mistakes

A modern kitchen in Germany is often a compromise between functionality and limited space. The desire for a single appliance that can defrost, heat, grill, and even bake leads many to the convection and grill microwave. However, the market is flooded with models whose promises often fall short in practice. Before you make a decision, it's crucial to understand the common pitfalls that lead to disappointment and unnecessary expense.

This guide will help you see through the marketing hype and find an appliance that truly fits your needs. We focus on the critical technical features and show you what to look for to make an informed choice.

The 3 Most Common Pitfalls When Buying a Combi-Microwave

Many appliances advertise an impressive range of functions, but the reality is often quite different. Watch out for these three common problems to avoid a bad purchase.

1. Weak Grill and Convection Performance: A frequent annoyance is a 3-in-1 microwave whose additional functions exist only on paper. An underpowered grilling element (often under 1000 watts) browns food slowly and unevenly. Poorly designed hot air circulation means pizzas are still doughy in the middle while the edges are already burnt. The result is not a full-fledged oven replacement, but an expensive gimmick.
2. Misleading Interior Capacity Specs: Manufacturers state the volume in litres, but this figure says little about the actual usable space. A large turntable in a 25-litre appliance can make it impossible to use rectangular casserole dishes. The usable diameter and internal height are often the more important measurements, but they are rarely advertised prominently.
3. Complex and Unhygienic Cleaning: Exposed heating elements on the ceiling of the cavity and hard-to-reach fans for the convection air are breeding grounds for grease and food residue. After just a few uses for grilling or roasting, heavy smoke and unpleasant odours can occur if cleaning is not straightforward. An easy-to-clean stainless steel interior is often a better choice here than a simple painted surface.

What Really Matters: The Decisive Parameters

To separate the wheat from the chaff, you should focus on objective, technical criteria. These three aspects are crucial for the performance and longevity of your combination microwave.

Consider Power Ratings Separately

The total power output is irrelevant. Pay attention to the separate wattage for each function:

• Microwave Power: For rapid heating and cooking, 800 to 1000 watts is a good benchmark.
• Grill Power: To create a beautiful crust, the grill should have at least 1200 watts. Anything less often leads to disappointing results.
• Convection Power: For a true microwave with an oven function, 1500 to over 2000 watts are required to reach and evenly maintain temperatures of up to 230°C.

Interior Design: Turntable or Flatbed?

The design of the interior determines how flexibly you can use the appliance.

• Models with a Turntable: The classic design. The diameter of the plate (e.g., 28 cm) limits the size of your cookware.
• Microwave without a turntable (flatbed): These models use a flat ceramic or glass base with a rotating antenna underneath to distribute the microwaves. The advantage is a larger, fully usable surface that is also suitable for rectangular casserole dishes or for cooking on two levels with a wire rack.

Materials and Extra Features

A stainless steel interior is not only more durable and hygienic than painted steel but also reflects heat better, which can lead to more even results. Useful extra features that offer real value include:

• Combination Programmes: Simultaneous use of the microwave and grill or convection to shorten cooking times and prepare food that is juicy on the inside with a crispy crust.
• Crisp Function: A special function that often uses a combination of the grill, microwaves, and a coated crisp plate to bake dishes like pizza or chips until they are crispy on the top and bottom.
• Automatic Programmes: Preset programmes for common dishes simplify operation and ensure reliable results for baking and grilling.

Frequently Asked Questions (FAQ)

Can a convection microwave completely replace a full-sized oven? For many everyday tasks like baking pizza, reheating rolls, preparing casseroles, or smaller cakes, a powerful freestanding combination microwave is an excellent substitute. However, for very large roasts, multiple trays of baked goods at once, or special baking requirements that need precise top and bottom heat, a traditional built-in oven may still have advantages in terms of size and precision.

What is the difference between a grill function and a crisp function? The standard grill function browns food from above using a heating element. A microwave with a crisp function is a more advanced system. It typically combines the top grill with microwaves that cook the food, and a special, non-stick crisp plate. This plate is heated intensely by the microwaves, creating a crispy, browned base—ideal for pizza, quiche, or chips.

How do you effectively clean the grill and convection area? Always read the manufacturer's instructions. As a general rule, wipe the interior with a damp cloth after each use to prevent food residue from burning on. Models with a stainless steel interior have a clear advantage here. Some appliances offer special cleaning programmes, often steam-based, that soften stubborn dirt. Never use abrasive cleaners or steel wool on the heating elements or in the interior, as this can damage the surfaces.
