Combination Microwave with Convection and Grill: Buyer's Guide

A combination microwave with convection and grill promises to merge three appliances into one: it reheats, grills to a crisp, and bakes like a small oven. For small kitchens, offices, or single-person households, such a combi microwave seems to be the ideal, space-saving solution. In practice, however, many models turn out to be costly disappointments. Before you make a decision, it's crucial to understand the common pitfalls that often only become apparent after the purchase.

As your Joybuy Product Recommendation Officer, I'll help you distinguish between marketing promises and genuine performance features. We'll focus on the facts so you can find an appliance that truly makes your daily life easier.

The most common problems with combination appliances are:

1. The "Convection" Deception: Many budget models advertise a convection function that, in reality, consists of nothing more than a weak fan. The result: pizzas remain soggy, cakes don't rise, and the feature is little more than a marketing gimmick. A true microwave with an oven function requires adequate heating power.
2. Complicated Operation: An appliance with many functions can quickly become confusing. If selecting the right program takes longer than the cooking itself, the convenience is lost.
3. Hard-to-Clean Interiors: Burnt-on food residue in a lacquered cavity is extremely difficult to remove. An easy-to-clean stainless steel interior is often the better choice, but it isn't always clearly stated.

What Really Matters: The Decisive Features of a Combi Microwave

To avoid these problems, you should carefully examine three technical aspects before buying. These determine whether a 3-in-1 microwave can live up to its promises.

Interpreting Power Correctly: More Than Just Microwave Watts

The total power of an appliance is composed of three values, each relevant for different tasks:

• Microwave Power (approx. 700–1000 watts): This value is crucial for quickly heating and defrosting food. 800 watts is a good standard for most households.
• Grill Power (approx. 1000–1300 watts): A powerful quartz or infrared grill ensures a crispy crust on gratins or cheese on toast.
• Convection Power (min. 1200 watts): This is the most critical value for the oven function. Appliances with less than 1200 watts often struggle to generate the even heat necessary for baking cakes or achieving a crispy pizza function. For serious baking ambitions, models with 1500 watts or more are recommended.

Cavity Volume and Interior: Size Isn't Everything

The volume of the interior cavity is given in litres and should suit your household:

• Up to 20 litres: A 20-litre microwave is compact and ideal for singles or couples who mainly prepare single-plate meals or small portions.
• 23 to 28 litres: This standard size offers enough space for a typical frozen pizza or a medium-sized casserole dish. It's a good compromise between footprint and flexibility.
• Over 30 litres: Large models are suitable for families or if the appliance will be regularly used as a full-fledged oven replacement, for example, for a whole roast chicken.

Also, pay attention to the interior material. A lacquered cavity is inexpensive but prone to scratches and difficult to clean. A stainless steel cavity is more robust, hygienic, and reflects microwaves better, which can contribute to more even cooking.

Useful Extra Features: From Pizza Function to Auto-Programs

Modern appliances offer a variety of automatic programs. Instead of being dazzled by a high number, check which ones are relevant to you. Particularly useful are:

• Combination Programs: The ability to use the microwave, grill, and convection simultaneously saves time and often delivers better results. For example, the microwave cooks a chicken quickly, while the grill and convection create a crispy skin.
• Weight-Based Defrost: The appliance determines the optimal defrosting time based on the weight of the frozen food.
• Specialty Programs: A dedicated pizza function that optimally combines convection and bottom heat (if available) is a clear plus.

Can a combination microwave with convection really replace an oven? For many everyday tasks like baking pizza, reheating bread rolls, or preparing casseroles, a high-quality combi microwave with strong convection power (over 1500 W) can replace a conventional oven, especially in small households. However, it reaches its limits with very large roasts or when baking on multiple levels simultaneously.

How many watts should a good combi microwave have? Pay attention to the individual power ratings. A good guide is: at least 800 W for the microwave, 1000 W for the grill, and, most importantly, at least 1200 W for the convection function. More powerful models with 1500 W of convection or more offer better and more even baking performance.

What is the advantage of an appliance without a turntable? Some modern appliances, often called "flatbed" models, do away with the turntable. The main advantage is flexibility: the entire flat bottom of the cavity can be used, which allows for the use of square casserole dishes or larger plates that would get stuck on a turntable. Additionally, cleaning the smooth bottom is easier.
