I still remember the first time I saw a convection microwave oven. I thought, “Oh, it’s just a fancy microwave with extra buttons.” Boy, was I wrong. That so-called “fancy” appliance has since become my go-to for everything from baking cakes to roasting chicken and even reheating leftover pizza to crispy perfection. If you’re new to this incredible kitchen tool and wondering how to use a convection oven microwave, you’re in the right place.

This guide is here to walk you through everything I learned—the easy way and the hard way—so you don’t make the same mistakes. I’ll explain how it works, how to switch between modes, what you can (and can’t) put inside, and how to use it for everyday meals. Whether you’re a home cook, a busy parent, or someone living in an RV, this article will help you master your convection microwave with ease.

Let’s get into it.

What Is a Convection Microwave Oven—and How Does It Work?

So, how does a convection oven work in a microwave? To answer that, let’s break down what makes this appliance special.

A standard microwave oven uses electromagnetic waves to heat food quickly. It vibrates water molecules, which generates heat and cooks your food from the inside out. A convection oven, on the other hand, has a heating element and a fan that circulates hot air, much like a traditional oven. When you combine both in a single appliance, you get the best of both worlds.

In convection mode, the fan distributes heat evenly, allowing you to bake, roast, and crisp. In microwave mode, you can reheat or cook quickly. There’s also often a grill mode, which uses an upper heating element to add browning.

So what is a convection microwave and grill microwave? It’s a multitasking wonder that lets you microwave, bake, and grill without needing three separate appliances. Perfect for small kitchens, dorms, or RVs.

How to Use a Convection Oven Microwave Like a Pro

When I first got mine, I was intimidated by all the modes and settings. But once you understand the basics, it’s actually super simple. Here’s how to use a convection oven microwave effectively:

Know Your Modes: Most models have at least three modes: microwave, convection, and grill. Some allow combination modes for even more versatility.
Read the Symbols: Look for the convection mode symbol in your microwave—usually a fan icon.
Switching Modes: Press the “Mode” or “Function” button to toggle between microwave, convection, and grill.
Use the Right Tools: When using convection, you can place food on metal racks or trays. Avoid using plastic, even if it says “microwave-safe.”
Understand the Presets: Many convection ovens come with auto-cook options. These are handy for beginners.

I recommend skimming through your manual—especially if you have a GE Profile or KitchenAid microwave convection oven. Their manuals often include helpful presets and conversion charts.

How to Bake in a Microwave Convection Oven (Cakes, Cookies & More)

One of the most exciting things you can do is bake. So how to bake in a microwave convection oven?

Baking Guide:

Preheat First: Always preheat your oven just like a traditional oven. Set the temperature (usually between 325°F and 375°F) and wait for the beep.
Choose the Right Cookware: Use metal, glass, or ceramic baking dishes. Silicone molds also work great.
Set the Timer and Temp: Use standard baking temps but reduce the time slightly since convection cooks faster.

How to Preheat a Convection Microwave:

Most ovens have a “Preheat” button in convection mode. Select your desired temperature, hit start, and wait. Don’t skip this step—it makes a huge difference in how evenly your food bakes.

Easy Recipes to Try:

Chocolate Chip Cookies: Bake at 350°F for 10-12 minutes.
Banana Bread: 325°F for 40-45 minutes.
Mini Pizzas: 375°F for 12-15 minutes.

These convection microwave recipes come out just as good as using a full-size oven.

Can You Put Metal in a Convection Microwave?

Here’s a question I had: Can you put metal in a convection microwave oven? The answer is yes—but only when using convection or grill modes.

Safe Cookware Guide:

OK in Convection Mode:
- Stainless steel trays
- Aluminum foil (but don’t let it touch the sides)
- Metal racks (usually included)
Never in Microwave Mode:
- Foil, metal pans, or even mugs with metallic trim

Using the wrong materials in microwave mode can cause sparks or even fires, so always double-check what mode you’re in.

If in doubt, refer to your user manual. Brands like GE and KitchenAid offer PDFs online with detailed charts.

What’s the Best Way to Use a Convection Oven Microwave Daily?

You might wonder: what is the best way to use a convection oven every day? The answer depends on your lifestyle, but here are my go-to routines:

Daily Uses:

Breakfast: Toast bagels using grill mode
Lunch: Bake a potato using convection mode
Dinner: Roast chicken breasts with veggies on the metal rack
Snacks: Reheat pizza slices (they come out crispy, not soggy!)

Tips

Use the right rack level
Don’t overcrowd the tray
Flip or rotate halfway for even cooking

I also use mine for weekly meal prep—from roasted veggies to baked pasta.

Disadvantages of a Convection Microwave Oven

Of course, no appliance is perfect. What is the disadvantage of a convection microwave oven?

Convection Microwave Oven Disadvantages:

Preheating Takes Time: Unlike standard microwaves, you need to wait.

Power Consumption: Convection mode uses more electricity.

But honestly, once you get used to it, these are minor drawbacks.

RV Cooking Tips:

Check the Voltage: Make sure your RV can handle the power load.
Use Multi-Purpose Cookware: Space is limited, so invest in dishes that work in all modes.
