Combination Microwave Oven Buying Guide: Choosing the Right Model

In our modern kitchens, where space is at a premium, optimising every square inch is essential. Between the stand mixer, the coffee machine, and the toaster, countertops can get cluttered fast. This is where the combination microwave oven emerges as an invaluable ally. Capable of defrosting, reheating, grilling, and even baking like a conventional oven, it's the Swiss Army knife of the contemporary kitchen.

This guide is here to help you make sense of it all. We'll break down the essential selection criteria and present our top picks for 2026. The goal: to help you find the perfect appliance that fits your habits and your budget.

Key Factors for Choosing the Right Combination Microwave

Faced with a jungle of features, choosing the right appliance can quickly become a headache. To ensure you make the right choice, here are the essential criteria to scrutinise.

1. Capacity and Power: The Right Size and Strength for Your Household

Expressed in litres (L), the capacity determines the size of the dishes you can fit inside. For a single person or a couple, a 20 to 25-litre model will be more than enough. A family of three to four should look for a large-capacity microwave between 25 and 35 litres. Beyond that, models over 35 litres are aimed at large families and those who love to entertain.

Power, measured in watts (W), is crucial: it dictates the speed of cooking and defrosting. For the microwave function alone, 900?W is a good baseline. For the grill and convection functions, higher power guarantees more even cooking and much crispier results.

2. Cooking Modes: More Than Just a Reheating Box

The key advantage of a combination microwave oven is its versatility. Here’s an overview of the game-changing functions:

  • Grill Function: Essential for browning and grilling a pan of lasagne or a potato gratin. The top heating element provides that much-loved crispy finish.
  • Convection Heat: This is the function that turns your microwave into a true mini-oven. A fan circulates hot air for perfectly even cooking. Sunday roasts, cakes, and quiches are all within reach, with stunning results that are very close to those of a conventional oven.
  • Steam Cooking: Some models offer an accessory or a dedicated function for steam cooking. This is a real bonus for healthily cooking vegetables, fish, or rice while preserving their nutrients and flavours.

3. Automatic Programmes and Maintenance: The Details That Make Life Easier

Automatic programmes simplify your life in the kitchen. Just select the type of food and its weight, and the appliance does the rest by adjusting the power and duration. Automatic defrost functions, in particular, are a valuable time-saver.

Finally, one point you should never overlook is maintenance. A cavity with a non-stick coating or, even better, a self-cleaning one (catalytic or pyrolytic on the most premium models) will save you a lot of cleaning chores when dealing with grease splatters.

Frequently Asked Questions

What's the difference between a combination microwave and a microwave with a grill? A microwave with a grill simply adds a top heating element to brown dishes. The combination microwave oven goes much further: it incorporates convection heat (a fan that circulates hot air) to bake, roast, and even prepare pastries like a real oven. In short, it's in a different league.

Can a combination microwave really replace a conventional oven? Absolutely! For most everyday dishes, the results are stunning. A good convection model can easily roast a chicken, bake a cake, or perfectly brown a gratin. Its added advantage: ultra-fast preheating and reduced cooking times. Only high-precision baking purists will still find an advantage in a traditional oven, but for everyone else, the combination microwave is a remarkably effective solution.

What capacity should I choose for my combination microwave? It all depends on the size of your household and your cooking habits. Here are a few guidelines to help you:

  • Under 25 L: For a single person or a couple.
  • 25 L to 32 L: Suitable for a family of 3 to 4 people.
  • Over 32 L: Recommended for large families (5 or more people) or if you regularly cook large dishes.
