Why Do Frozen Sliders and Frozen Burgers Burn in the Air Fryer?

Are your frozen sliders and burgers burning in the air fryer? It’s because you have to separate the slider or burgers first! Especially when it comes to burgers with thick frozen meat patties, you just can’t air fry the whole thing at once. Separating the burgers and sliders allows you to have a hot patty and melty cheese.

If you’re air frying frozen burger patties, follow the same method we show below. But you will have to air fry the burger patty longer. Depending on the size and model of your air fryer, timing will change. Add about another 2 minutes to our suggested time below. Check on the burger and if you need more time, add another minute until it’s cooked to your preferred doneness.

Do not thaw the sliders before air frying. Don’t air fry the sliders whole. By the time the meat patty is heated, the top bun would be super crispy. You’ll want to remove the top bun and air fry the bottom bun and meat patty first. Then add the top bun to the air fryer and heat it up too.
