A toaster oven can handle some microwave jobs but not all of them
A toaster oven and a microwave heat food in completely different ways, so they are not true replacements for each other. A microwave uses radiation to agitate water molecules inside food, heating it fast and keeping the outside cool. A toaster oven uses heating elements to warm the air around food, like a regular oven but smaller. This means a toaster oven can brown, crisp, and bake—things a microwave cannot do—but it takes longer and uses more counter space.
Whether you can swap one for the other depends on what you actually cook. If you mostly reheat leftovers, defrost meat, or warm beverages, a microwave is faster and uses less energy. If you want crispy toast, melted cheese, roasted vegetables, or baked goods, a toaster oven is the better tool. Many home cooks find they need both because the jobs they do are genuinely different.
Key Takeaways
- A toaster oven browns and crisps food; a microwave reheats it quickly without browning, so they handle different cooking tasks.
- Reheating leftovers, defrosting, and warming drinks are faster in a microwave and use less electricity.
- A toaster oven works better for anything you want crispy, melted, or browned—pizza, cheese, roasted vegetables, baked goods.
- Toaster ovens take up more counter space and heat the kitchen more than microwaves, which matters in small spaces or warm climates.
- Many households benefit from keeping both because they solve different problems, not because one is strictly better.
What a toaster oven does better than a microwave
A toaster oven excels at any task where you want texture on the outside of the food. Reheating pizza in a microwave makes the crust soggy; a toaster oven at 350°F for 5 to 8 minutes restores crispness. Leftover fried chicken stays crispy. Cheese melts and browns instead of turning rubbery. Bread toasts evenly without hot spots.
Toaster ovens also handle small baking jobs that a full-size oven makes wasteful. A batch of 8 to 12 cookies, a small casserole, or a single sheet of roasted vegetables cooks faster and heats your kitchen less than turning on a full oven. If you bake regularly but in small quantities, a toaster oven can reduce your cooking time by 10 to 15 minutes per session.
Defrosting in a toaster oven is slower than in a microwave but more even. Microwave defrosting can cook the edges while the center stays frozen; a toaster oven at 200°F takes 20 to 40 minutes for a small chicken breast but thaws it uniformly without starting to cook it.
What a microwave does better than a toaster oven
A microwave reheats most foods in 1 to 3 minutes. A toaster oven takes 8 to 15 minutes to preheat and then heat the food. If you reheat leftovers several times a day, the time difference adds up. A microwave also uses about one-third the electricity of a toaster oven for the same job, which matters if you are on a tight budget or live somewhere with high energy costs.
Microwaves are better for heating liquids. Warming a cup of coffee, heating water for tea, or thawing soup happens in 2 to 4 minutes in a microwave. A toaster oven would take 10 to 15 minutes and would heat your kitchen unnecessarily. Microwaves also do not brown or dry out foods the way toaster ovens can if you are not careful with timing.
If counter space is limited, a microwave takes up roughly half the footprint of a toaster oven. In a small kitchen, dorm room, or RV, this difference is real. Microwaves also produce less ambient heat, which matters in warm climates or during summer.
Foods that work in a toaster oven but not a microwave
Anything you want crispy or browned should go in a toaster oven. This includes pizza, garlic bread, quesadillas, nachos, leftover fried foods, and roasted vegetables. Baked goods like cookies, biscuits, and small cakes also need a toaster oven—a microwave will make them rubbery or unevenly cooked.
Cheese-topped dishes benefit from a toaster oven because the cheese browns and bubbles instead of turning into a rubbery layer. Casseroles, enchiladas, and gratins all finish better in a toaster oven at 350°F for 12 to 20 minutes than in a microwave.
Foods with a sauce or glaze that you want to set also work better in a toaster oven. The dry heat helps the sauce thicken and adhere to the food instead of staying wet and separated.
Foods that work in a microwave but not a toaster oven
Anything that needs to stay moist and soft should go in a microwave. Steamed vegetables, rice, pasta, and grains all reheat better in a microwave because the moisture stays trapped. A toaster oven can dry them out unless you add liquid and cover them.
Soups, stews, and sauces heat evenly in a microwave without the risk of the edges drying out while the center stays cold. Beverages—coffee, tea, milk, water—heat much faster in a microwave. Defrosting ground meat or small cuts of chicken is also quicker in a microwave, though less even.
Foods that splatter or steam heavily also work better in a microwave because the moisture stays contained. Corn on the cob, artichokes, and steamed dumplings all cook faster and cleaner in a microwave.
Space and energy trade-offs to consider
A toaster oven typically measures 16 to 20 inches wide and 8 to 10 inches deep. A microwave is usually 24 to 30 inches wide but only 4 to 6 inches deep, so it takes up less vertical space but more counter length. If your counter is narrow, a microwave might fit better. If your counter is deep, a toaster oven might work.
Energy use varies by model, but a microwave uses roughly 600 to 1000 watts while cooking, and a toaster oven uses 1200 to 1800 watts. For a single reheating task, the difference is small—a few cents. But if you reheat food multiple times a day, a microwave saves money over months.
Toaster ovens also heat the kitchen more noticeably than microwaves. In summer or in a small space, this can raise your cooling costs. In winter, some people view this as a benefit because it reduces heating needs, though the math rarely works out in your favor.
Deciding whether you need both or can choose one
If you live alone or in a small household and mostly reheat leftovers and warm beverages, a microwave is probably enough. If you bake, cook with cheese, or want crispy food regularly, a toaster oven is worth the counter space.
If you have room for both, keeping both is the practical choice. They solve different problems, and the time you save by using the right tool for each job adds up. A microwave for quick reheats and a toaster oven for anything you want crispy or browned covers almost every common cooking task.
If you must choose one, think about your actual cooking patterns over the past month. Count how many times you reheated something versus how many times you wanted something crispy or browned. Whichever happened more often should guide your choice.
Frequently Asked Questions
Can I use a toaster oven to defrost meat?
Yes, but it is slower than a microwave. Set the toaster oven to 200°F and place the meat on a tray. A small chicken breast takes 20 to 40 minutes; larger cuts take longer. The advantage is even thawing without cooking the edges. The disadvantage is time—a microwave does the same job in 5 to 10 minutes.
Will a toaster oven dry out my leftovers?
It can, especially if you reheat for too long or do not cover the food. A toaster oven at 350°F for 8 to 12 minutes works for most leftovers if you cover them with foil. A microwave is safer because it heats the food itself rather than the air around it, so drying is less likely.
How long does it take to reheat food in a toaster oven?
Plan on 3 to 5 minutes of preheat time plus 8 to 15 minutes of cooking time, depending on the food and how full the oven is. A microwave does the same job in 1 to 3 minutes total. If you reheat frequently, the time difference is significant.
Can I bake cookies in a toaster oven?
Yes. A toaster oven works well for small batches of 8 to 12 cookies. Bake at 350°F for 10 to 12 minutes, checking at 9 minutes because toaster ovens heat unevenly. Rotate the tray halfway through if the cookies brown faster on one side.
Is a toaster oven worth it if I already have a microwave?
It depends on what you cook. If you never want crispy food or bake, probably not. If you eat pizza, roasted vegetables, or baked goods even occasionally, a toaster oven pays for itself in convenience and food quality within a few months.
