Instructions for reheating a McDonald’s Hamburger in the microwave

  1. Place on microwaveable plate in its packaging
  2. Microwave for 30 seconds
  3. Microwave for further 10-second bursts until steaming hot

Microwave tip 1: If the Hamburger was in the fridge, damp a kitchen roll and wrap the burger in that instead of the wrapper, this will introduce steam and help make the stale bun soft again.

Microwave tip 2:  Let the Hamburger cool down before you take a bite because they get incredibly hot very quickly in the microwave.

Can you reheat a McDonald’s Hamburger in the oven?

You can reheat a Hamburger in the oven, but it will dry out easily, so don’t skip any of the tips below. 

Preheat your oven to 180°C. Remove the burger patty from the Hamburger’s bun, scrape the ketchup, mustard, pickles and onions from the patty and bun, and save on a plate.  

Sprinkle a few drops of water onto the patty and all parts of the bun and wrap them individually in foil loosely. 

Add the patty to the preheated oven. After 5 mins, add the top and bottom of the bun to the oven and continue to reheat for another 5 mins or until steaming hot.

Remove the bun and patty from the oven, reconstruct the Hamburger, and put the ketchup, mustard, pickles and onions back. 

TIP: I do not reheat the bread as it gets dry. In my opinion, there is enough heat from the freshly reheated patty. So if you can handle a slightly cooler bun, Scrape the ketchup, mustard, pickles and onions straight on the bun lid, reheat the patty, slide it back in, and eat immediately.

Can you reheat a McDonald’s Hamburger in the air fryer?

You can reheat a Hamburger in the air fryer. The following tips will help you make it as close to fresh as possible.

First, deconstruct your Hamburger and save the ketchup, mustard, pickles and onions for later. Add a few drops of water to the patty and both parts of the bun.

Next, add the patty to the air fryer at 180°C. 

After 3 mins, add both parts of the bun to the air fryer and toast with the burger for 30-45 seconds.

Remove all Hamburger parts from the air fryer and rebuild and replace the ketchup, mustard, pickles and onions.

TIP: As with the oven method, I do not personally reheat the bread in the air fryer as it can get a bit dry. In my opinion, there is enough heat from the freshly reheated patty. So if you prefer a softer bun, scrape the ketchup, mustard, pickles and onions straight on the bun lid, reheat the patty, slide it back in, and eat immediately.
