One of the easiest ways to avoid wasting food is to take home leftovers, even when it comes to fast food. However, it may be tricky to figure out how to reheat your fast food burger while preserving its flavor, and this crucial step, combined with the right techniques, will ensure it comes out as good as possible.

Make sure to deconstruct your burger before reheating, or else some components will remain cold, especially the ones in the middle. Separate the meat, buns, vegetables, and scrape off any sauces; while veggies and condiments can be added back to the burger, you may want to replace them with fresh ones instead.

For the patty and bun, reheat them in either a frying pan or an oven, though we recommend the oven for the most even heat distribution. If you go with the oven, place the meat and bun on a baking sheet and bake in the oven for about six minutes at 350 degrees Fahrenheit; then, you’re free to reassemble and chow down.
