According to a 2025 survey by the Association of Home Appliance Manufacturers, nearly 40% of U.S. households now own an air fryer. That number has doubled since 2020. Meanwhile, the microwave — a fixture in 90% of American kitchens — remains the most-used cooking appliance. This raises a practical question for anyone trying to cut countertop clutter: does an air fryer replace a microwave? As someone who has tested hundreds of kitchen products over the years, I can tell you the ones that last are never the flashiest — they are always the simplest, heaviest, and most boring-looking tools in the entire drawer. The air fryer is flashy. The microwave is boring. Which one deserves your limited counter space?
Key Takeaways
- An air fryer cannot replace a microwave for speed — microwaves heat food in seconds, while air fryers take minutes to preheat and cook.
- Air fryers excel at restoring crispiness to fried foods, which microwaves turn soggy.
- For simple reheating of soups, leftovers, or beverages, the microwave remains faster and more efficient.
- If you have room for only one, consider a microwave air fryer combo to get the best of both worlds without sacrificing counter space.
How Air Fryers and Microwaves Actually Work
To understand whether an air fryer can replace a microwave, you first need to know how each appliance heats food. They use completely different physics, and that difference determines what each does well.
The Science Behind an Air Fryer
An air fryer is essentially a small, high-velocity convection oven. A heating element at the top gets hot, and a powerful fan circulates that hot air at speeds up to 30 miles per hour. This rapid air movement transfers heat to the surface of the food, causing the Maillard reaction — the browning and crisping that creates texture and flavor. Because the air is dry, moisture on the food’s surface evaporates quickly, leaving a crispy exterior.
Most air fryers operate between 300°F and 400°F. They require a preheat time of 3 to 5 minutes before cooking. The total cook time for most frozen foods ranges from 10 to 20 minutes.
The Science Behind a Microwave
Microwaves use electromagnetic radiation at a frequency of 2.45 GHz. These waves penetrate food and cause water molecules to vibrate, generating heat through friction. This heats food from the inside out, but it does not create browning or crisping. In fact, the steam generated by the heated water molecules makes food soft and, often, soggy.
Microwaves operate at power levels from 600 to 1200 watts. Most foods reheat in 1 to 3 minutes. There is no preheat time — you press a button and the food gets hot immediately.
Where an Air Fryer Beats a Microwave
For certain tasks, an air fryer is undeniably better. If your primary concern is texture — specifically crispiness — the air fryer wins every time.
Reheating Leftover Fried Foods
French fries, chicken wings, onion rings, and pizza slices all turn limp and sad in a microwave. The steam created by the microwave softens the breading and crust. In an air fryer, the circulating hot air re-crisps the exterior while warming the interior. French fries go from soggy to crunchy in 4 to 5 minutes at 375°F. Pizza gets a crispy bottom and bubbly cheese in about 3 minutes at 350°F.
Cooking Frozen Foods
Frozen mozzarella sticks, tater tots, and fish fillets come out of an air fryer with a texture that rivals deep-frying. The microwave turns them into a steamy, limp mess. Most frozen foods cook in 10 to 15 minutes in an air fryer, compared to 2 to 4 minutes in a microwave — but the difference in quality is enormous.
Roasting Vegetables
Air fryers excel at roasting vegetables. Broccoli, Brussels sprouts, and carrots develop caramelized edges in 8 to 12 minutes at 375°F. A microwave would simply steam them, producing a soft, bland result. If you eat vegetables regularly, an air fryer can replace a microwave for this single task alone.
Where a Microwave Beats an Air Fryer
Despite the air fryer’s advantages, the microwave still dominates in several critical areas. If speed is your priority, the microwave is irreplaceable.
Reheating Soups, Stews, and Sauces
Liquid-based foods are the microwave’s specialty. A bowl of soup goes from refrigerator temperature to steaming hot in 2 to 3 minutes. In an air fryer, you would need to transfer the soup to an oven-safe bowl, preheat for 5 minutes, then cook for another 10 minutes — and even then, the surface might dry out. The microwave is simply faster and more effective for liquids.
Defrosting Frozen Meat
Most microwaves have a defrost setting that thaws ground beef, chicken breasts, or fish fillets in 5 to 10 minutes. An air fryer cannot defrost food at all — it cooks from frozen, which often leads to uneven results. If you regularly need to defrost ingredients quickly, you need a microwave.
Quick Snacks and Beverages
Heating a mug of water for tea, melting butter for a recipe, or warming a tortilla takes 30 seconds in a microwave. An air fryer requires preheating and a longer cook time for even simple tasks. For these everyday micro-uses, the microwave is the more practical tool.
Can an Air Fryer Replace a Microwave Entirely?
The short answer is no — not for most households. But the longer answer depends on your cooking habits.
If You Rarely Reheat Leftovers
If you cook fresh meals every day and only use the microwave for the occasional frozen snack, an air fryer could work as your primary appliance. You will lose the ability to quickly reheat soups or defrost meat, but you can plan around those limitations. For example, you can defrost meat overnight in the refrigerator and reheat soups on the stovetop.
If You Eat a Lot of Fried Foods
For someone who regularly eats frozen fries, chicken nuggets, or fried chicken, the air fryer is a better fit. The microwave will never deliver the same texture. In this case, you might find yourself using the air fryer 80% of the time and the microwave only for liquids and defrosting.
The Combo Solution
If you have limited counter space but need both functions, consider a microwave air fryer combo. These units combine a standard microwave with a convection heating element and a crisper tray. They can reheat soup in 2 minutes and crisp chicken wings in 12 minutes. They are larger than a standard microwave but smaller than having two separate appliances. For 2026, several manufacturers have improved the crisping performance to nearly match standalone air fryers.
Practical Scenarios: Which Appliance to Use
Here is a quick reference for common kitchen tasks and which appliance handles them best.
- Reheating pizza: Air fryer at 350°F for 3 minutes. Microwave makes the crust chewy.
- Reheating soup: Microwave for 2 to 3 minutes. Air fryer takes too long and dries the surface.
- Cooking frozen french fries: Air fryer at 375°F for 12 minutes. Microwave turns them soggy.
- Defrosting ground beef: Microwave defrost setting for 5 to 7 minutes. Air fryer cannot defrost.
- Melting butter: Microwave for 20 seconds. Air fryer is overkill.
- Roasting vegetables: Air fryer at 375°F for 10 minutes. Microwave steams them.
- Heating a frozen burrito: Microwave for 2 minutes, then air fryer at 350°F for 3 minutes for a crispy exterior.
Counter Space and Lifestyle Considerations
Beyond cooking performance, the decision comes down to how you use your kitchen. A standard microwave takes up about 1 to 1.5 square feet of counter space. An air fryer takes up roughly the same footprint, but many models are taller. If you have limited counter space, keeping both may not be practical.
I have tested dozens of air fryers and microwaves over the years. The most common feedback I hear from people who tried to replace their microwave with an air fryer is that they missed the speed for simple tasks. They ended up buying a cheap microwave again within six months. The air fryer is a fantastic tool, but it is not a universal replacement.

Final Verdict
Does an air fryer replace a microwave? For most people, no. The two appliances serve different primary functions. The microwave is unmatched for speed and handling liquids. The air fryer is unmatched for texture and browning. If you can only keep one, consider your most frequent cooking tasks. If you reheat leftovers daily, keep the microwave. If you cook frozen foods and vegetables regularly, the air fryer may be more useful.
For those who want both without the clutter, the best solution is a combo unit. Check out our picks for the best air fryer microwave combo top picks for 2026 to find a model that fits your kitchen.
