Reheating leftovers can be disappointing — soggy fries, rubbery pizza, or dried-out chicken are enough to make anyone skip last night’s dinner. But with an air fryer, you can bring leftovers back to life with the taste and texture of a fresh meal. In this guide, we’ll show you how to reheat leftovers in an air fryer the right way — simple, efficient, and perfect for beginners.
Why Reheating Leftovers in an Air Fryer Works
Air fryers use rapid air circulation to heat food from all sides, creating a crisp finish without needing much oil. Unlike microwaves, which heat unevenly and make food limp, or ovens, which take a long time, an air fryer gives you the best of both worlds — fast and crispy.
- Even heating: Hot air circulation prevents soggy spots.
- Texture restoration: Be it fries, chicken wings, or pizza, you get that original crunch back.
- Energy-efficient: Uses less power and preheats faster than ovens.
- Zero waste: Helps you enjoy leftovers again instead of tossing them out.

What You’ll Need
Here’s what you’ll need to reheat leftovers in the air fryer:
- Your air fryer (any size or model works)
- Leftovers (pizza, fries, chicken, vegetables, etc.)
- Tongs or spatula (for easy flipping)
- Parchment paper or foil (optional, for easy cleanup)
- Cooking spray (optional, for keeping food moist or extra crisp)
Optional substitutes:
- Silicone liners work great instead of foil or parchment.
- A light brushing of oil instead of cooking spray adds crispness.
Best Way to Reheat Leftovers in an Air Fryer
Follow these easy steps to get perfectly reheated leftovers every time.
1. Preheat Your Air Fryer (If Recommended)
Some models don’t require this, but preheating (2–3 minutes at the target temperature) helps your food heat evenly and stay crisp.
Suggested preheat temperature: 350°F (175°C)
2. Arrange Leftovers in a Single Layer
Avoid crowding. Arrange leftovers in one even layer so the hot air can circulate properly. Overlapping or stacking causes uneven heating.
Pro tip: Reheat in batches if you have a large amount of food.
3. Set the Right Temperature
Different foods need different temperatures. Use this quick guide:
| Food Type | Temperature | Time (approx.) |
| French Fries | 350°F (175°C) | 3–5 minutes |
| Chicken Wings | 375°F (190°C) | 5–6 minutes |
| Pizza | 350°F (175°C) | 4–6 minutes |
| Fried Foods (nuggets, onion rings) | 370°F (188°C) | 4–5 minutes |
| Casseroles / Pasta Bakes | 325°F (160°C) | 7–10 minutes |
| Vegetables | 360°F (182°C) | 4–5 minutes |
(Adjust slightly depending on your air fryer model and portion size.)
4. Shake or Flip Halfway Through
For best results, pause halfway to flip your food or shake the basket. This ensures the underside crisps up evenly.
5. Check for Doneness
Open the basket near the end of cooking time and test the warmth and texture. If needed, add 1–2 more minutes. Air fryers heat quickly — so small adjustments go a long way!
6. Serve Immediately
Air-fried leftovers taste best fresh out of the basket. Let them cool slightly before serving and enjoy crisp, revived food that tastes freshly made.
Pro Tips & Best Practices
- Don’t overload the basket — air needs to circulate for crispness.
- Mist with oil if leftovers are dry (especially fried foods or baked items).
- Use lower temps for moist dishes like pasta or rice to avoid drying out.
- Avoid plastic or paper containers — use only heat-safe materials.
- Store leftovers properly before reheating — keep them refrigerated in airtight containers.
- Use the reheat function if your air fryer has one; it adjusts time and heat automatically.
Common Questions About Reheating Leftovers in an Air Fryer
1. Can I reheat multiple types of food together in the air fryer?
It’s best to reheat similar foods together (like fries and nuggets) since they share cook times. For mixed leftovers with different textures, reheat them separately for even results.
2. Do I need to add oil when reheating?
Not always. Many foods already contain residual oil from cooking. For dry items like breaded chicken or fries, a light spray can help restore crispness.
3. Can I reheat soup or saucy dishes in the air fryer?
Not recommended. Air fryers are best for solid or semi-solid foods. For soups, stews, or curry, use a stovetop or microwave-safe bowl instead.
4. What’s the best way to reheat pizza in an air fryer?
Preheat to 350°F (175°C), place slices in a single layer, and reheat for 4–5 minutes. The crust will crisp up nicely while the cheese melts evenly.
5. How can I reheat rice or pasta without drying it out?
Use a heatproof dish, cover it loosely with foil, and reheat at 325°F (160°C) for 7–10 minutes. Add a sprinkle of water to trap steam and prevent drying.
6. Is reheating leftovers in an air fryer safe?
Yes! Just ensure leftovers were stored properly (within 2 hours of cooking) and heated to a safe internal temperature of at least 165°F (74°C).
When Not to Use an Air Fryer to Reheat Leftovers
While the air fryer is versatile, it’s not ideal for everything. Avoid using it for:
- Liquid-based dishes (soups, sauces, gravies)
- Foods with delicate coatings (like tempura or soft pastries)
- Overly saucy pasta or curries (they can dry out or splatter)
- Cheese sauces or creamy dishes (may separate under high heat)
In these cases, the microwave or stovetop may be a better option.
Alternative Ways to Reheat Leftovers
If an air fryer isn’t available, here’s how other methods compare:
| Method | Pros | Cons |
| Microwave | Fast and convenient | Can make food soggy |
| Oven | Even heating for large portions | Takes longer and uses more energy |
| Stovetop | Great for stir-fries and moist dishes | Requires more cleanup |
| Toaster Oven | Crisps food fairly well | Less efficient than air fryer |
The air fryer stands out for its perfect blend of speed, crispness, and energy efficiency.
Conclusion: The Smart Way to Reheat Leftovers
Knowing how to reheat leftovers in an air fryer is a total game-changer for your kitchen routine. You’ll reduce food waste, save time, and enjoy meals that taste as good as the first time around. Whether it’s pizza night or last night’s takeout, the air fryer restores texture and flavor — fast.
Pro reminder: Always reheat safely, avoid overcrowding the basket, and adjust temperature to match your food type. Once you nail the basics, you’ll never go back to soggy microwave leftovers again.
