Recipe FAQs
Can You Cook White Castle Sliders in the Air Fryer?
Yes, you can cook White Castle sliders in the air fryer. The frozen version cooks up in under 10 minutes without defrosting required.
The bread, however, will get crispy. You can mitigate this by either wrapping the sliders in foil or separating the bun until halfway through cooking.
How Long to Cook White Castle Burgers in the Air Fryer?
White Castle burgers need to cook for about 10 minutes in the air fryer. Time may vary slightly between air fryer models, but this is the average time required.
A thermometer should reach 165°F in the middle for food safety purposes.
How Do You Reheat White Castle in an Air Fryer?
To reheat White Castle in an air fryer, place the sliders in the air fryer basket. Cook on the air fry setting for 3-4 minutes at 350°F, or until sliders are heated through.
This method works for both leftover fresh White Castle sliders, as well as frozen ones that have previously been cooked and stored in the refrigerator.
Why Are There No Pickles on Frozen White Castle Burgers?
There are no pickles on frozen White Castle burgers because they don’t reheat well. The pickles lose moisture and tend to become mushy and fall apart during reheating.
Instead, it is recommended to add your favorite pickle slices after heating your frozen sliders up.
Are White Castle Frozen Sliders Fully Cooked?
Yes, White Castle frozen sliders are fully cooked. You are simply reheating them.
That said, it’s still recommended to reheat to 165°F for food safety.
What is the Best Way to Cook Frozen White Castle Burgers?
The best way to cook frozen White Castle burgers largely depends on personal preference. However, it is generally in the microwave if you enjoy a soft texture, or in the air fryer if you prefer a crispier toasted texture on the buns.
You can also cook the burgers (removed from the buns) in the oven at 350F for 10-15 minutes, but this is the longest method, and you still usually need to microwave the buns for about 30 seconds to warm them.
White Castle Frozen Slider Tips and Tricks
- The reason I use foil is to prevent the overbrowning of the buns in the air fryer. While it’s an extra step, it gives you a much nicer looking burger bun
- That said, the very top crown of the bun will still get a bit crispy. However, the bread will stay soft underneath it, so it’s mostly superficial
- If you want to skip the foil, your other alternative is to pry off the top buns, and then add them in the last 1-2 minutes of cooking just to warm them up. I just find it tricky to pry off the frozen tops without losing some toppings
- You do not need to flip the burgers in the air fryer during cooking
- I have a Ninja Foodi Dual Zone air fryer and 10-12 minutes is just about right, depending how tight I pack them in there. Other air fryers may vary slightly
Storage and Reheating of White Castle Sliders
- Store any leftover White Castle sliders in an airtight container or zippered bag in your refrigerator for up to 3 days. Do not refreeze once they have been cooked once already
- To reheat White Castle sliders in the air fryer, cook at 350°F for 3-4 minutes, or until warmed through to your liking. If the tops start to brown too much, cover with foil (but you may not need to for this amount of time). Note this works with restaurant leftovers as well as the frozen sliders
