Cold fast food is grim, but the air fryer revives it brilliantly — crispy fries, hot juicy burgers, crunchy nuggets. The key is reheating each part separately. Here's how.
Key takeaways
Q: How do you reheat McDonald's in an air fryer?
A: Reheat at 180°C (360°F): fries 3–4 minutes, nuggets 3–5, and burgers 3–4 with the patty and bun separated.
Q: Should you reheat the whole burger together?
A: No — separate the patty from the bun and salad so nothing goes soggy or wilts.

Frequently asked questions
How do you reheat McDonald's in an air fryer?
Reheat at 180°C: fries 3–4 minutes, nuggets 3–5, and burger patties 3–4. Separate the burger and warm the bun for just the last minute.
Can you reheat a Big Mac in an air fryer?
Reheat the patties separately at 180°C for 3–4 minutes, warm the buns briefly, and rebuild with the cold salad and sauce so nothing wilts.
How do you make leftover fries crispy again?
Air fry them at 180°C for 3–4 minutes in a single layer — they crisp up far better than in a microwave.
