Reheating a complete, fully assembled McDonald’s Quarter Pounder (also known as a McRoyal with Cheese) in the air fryer is quick and keeps the burger solid without making a mess of the cheese or pickles.
Important Safety & Prep Tips
The Meat Rule: For food safety, meat should ideally only be reheated once. When buying fast food with the intention of saving it for later, try to purchase it during busy hours. This ensures the food hasn’t already been sitting under a heat lamp or reheated at the restaurant before you even bring it home.
Pro-Tip for Large Burgers: If you are reheating a particularly large burger, slicing it in half or into quarters before placing it in the air fryer basket will speed up the cooking time and ensure the center heats through evenly.
The Step-by-Step Reheating Method
First Side Heat:
Place the whole burger (or two, if they fit without overcrowding) into the air fryer basket, right-side up.
Set the temperature to 320°F (160°C) and cook for 3 minutes.
Flip and Heat:
Open the basket and carefully flip the burger upside down.
Run the air fryer at the same setting of 320°F (160°C) for another 2 minutes.
Check the Center:
After the initial 5 minutes, check the very center of the burger patty. Fast-food patties can easily remain cold in the middle even when the outside looks done.
If it isn’t piping hot yet, place the burger back in the basket right-side up (to prevent fillings or melting cheese from sliding out) and heat for an additional 2 minutes until the edges are sizzling.
Serve:
Once the center is thoroughly hot to the touch, remove it from the basket, slice it if desired, and serve.
