Toaster Oven vs Air Fryer vs Microwave: Which Countertop Appliance Replaces What?
Three appliances, overlapping functions, limited counter space. Here is what each actually replaces.
Most kitchens have a microwave. Many are adding an air fryer. Some already have a toaster oven. And the newest combo models try to be all three at once. The result is confusion about what you actually need -- and a lot of counter space wasted on redundant appliances.
This guide clarifies what each appliance does best, what it replaces, and which combinations make sense for different kitchen sizes. See What Toaster Oven Should I Buy? for model picks. Check when toaster oven prices drop.
What Each Appliance Actually Does Best
| Task | Toaster Oven | Air Fryer | Microwave |
|---|---|---|---|
| Toasting bread | Excellent | Cannot | Cannot |
| Crisping / air frying | Good (with convection) | Excellent | Cannot |
| Reheating leftovers | Good (maintains texture) | Excellent (re-crisps) | Fast but soggy |
| Baking (cookies, casseroles) | Excellent | Cannot | Cannot |
| Heating liquids / defrosting | Slow | Cannot | Fastest |
| Broiling | Excellent | Cannot | Cannot |
Key Insight
A toaster oven and a microwave have almost zero overlap -- they complement each other perfectly. An air fryer and a toaster oven with convection have significant overlap. The best two-appliance combo for most kitchens is a convection toaster oven + microwave. If you want crispier results specifically, add a basket air fryer as a third -- or get an air fryer toaster oven combo.
The Practical Combinations
| Kitchen Setup | Best For | Counter Impact |
|---|---|---|
| Microwave + Air Fryer | Small kitchens, minimal cooking | 2 small footprints |
| Microwave + Convection Toaster Oven | Most kitchens, good balance | 2 medium footprints |
| Microwave + Air Fryer Toaster Oven Combo | Best versatility, replaces 3 devices | 1 small + 1 large footprint |
| Air Fryer Toaster Oven only (no microwave) | Counter-space minimalists | 1 large footprint (but no defrosting/liquid heating) |
Frequently Asked Questions
Can an air fryer toaster oven replace a microwave?
For reheating and crisping food, yes. For heating liquids, defrosting, and speed, no. Most kitchens benefit from having both.
Is a toaster oven worth it if I have a full oven?
Yes -- it preheats in 3-5 minutes vs 10-15 for a full oven, uses less energy, and heats your kitchen less in summer. Worth it for small meals and sides.
Should I get a separate air fryer or an air fryer toaster oven?
Separate if you want maximum crispiness in a small footprint. Combo if you want versatility and are willing to trade slightly less crispiness for fewer devices.
