Preheat the Air Fryer: Begin by preheating your air fryer to around 350°F (175°C). Preheating ensures even reheating and crispiness.

Unwrap and Disassemble: Take your McDonald's burger out of its wrapper and disassemble it. If you have toppings like lettuce, tomato, onions, or pickles, consider removing them for reheating, as they may not reheat well in the air fryer.

Wrap in Aluminum Foil (Optional): If you want to prevent your burger from drying out, you can lightly wrap it in aluminum foil. Ensure that it's not wrapped too tightly to allow for proper air circulation.

Reheat the Patty: Place the burger patties (meat and cheese) directly into the air fryer basket. Cook them for approximately 2-3 minutes. Keep an eye on them to ensure they become hot and slightly crispy.

Reheat the Bun: While the meat and cheese are reheating, you can also place the burger buns in the air fryer, cut side up. Reheat them for about 1-2 minutes, or until they regain some of their texture.

Check for Doneness: After reheating, carefully open the foil (if used) and check the burger patties to ensure they have reached your desired level of warmth and crispiness. Cooking times may vary depending on your air fryer model.

Reassemble and Serve: Once the burger patties and buns are hot and crispy to your liking, reassemble your burger. You can add any toppings you removed earlier or customize it to your preference.

Enjoy Immediately: Serve your reheated McDonald's burger immediately while it's still warm and delicious. It's a great way to enjoy a classic fast-food favorite with a renewed and satisfying crunch.
