Wrap those burgers in foil like they're little presents of deliciousness, and remember, 5-6 minutes at 375 degrees is the sweet spot for that perfect crispy finish.

Preheat Air Fryer Properly

To ensure your frozen White Castle burgers cook perfectly, preheat your air fryer to 375 degrees Fahrenheit. Trust me, this step is like stretching before a workout—skip it, and you'll regret it.

Preheating might seem like a waste of time, but it's the secret sauce to getting that crispy bun and juicy patty combo you crave.

You've got a busy life, I get it. But waiting for your air fryer to reach that magic number is crucial. Think of it as the difference between a soggy, sad burger and one that makes your taste buds do a happy dance.

Preheating ensures the air fryer's ready to cook everything evenly and efficiently, so you're not biting into a half-frozen disaster.

Remember when you tried to speed things up by skipping steps? Yeah, that didn't go well. So, set your air fryer to 375 degrees, and let it do its thing. It's like letting your car warm up on a chilly morning—necessary for peak performance.

Trust the process, and you'll be biting into a White Castle burger that's crispy on the outside and perfectly cooked on the inside.

Wrapping Burgers in Foil

Next, get ready to wrap your frozen White Castle burgers in foil to lock in moisture and ensure even cooking. Trust me, you don't want those sliders drying out like your Aunt Linda's Thanksgiving turkey. Grab some aluminum foil and get wrapping. Think of it like tucking your burgers in for a cozy nap.

Make sure you seal that foil tight, like you're protecting your lunch from office fridge thieves. This nifty trick traps steam, keeping those buns soft and the meat juicy. Imagine the foil as a mini sauna for your burgers – minus the awkward small talk.

Once wrapped, toss them directly into the air fryer basket. No need for fancy trays or extra gadgets. Just you, the air fryer, and your foil-wrapped treasures. This method ensures they cook evenly, because let's face it, nobody likes a burger with a hot side and a cold side – it's not a McDLT.

And there you have it: your burgers are prepped and ready for their air fryer adventure. You're one step closer to biting into a hot, perfectly cooked White Castle slider, all while feeling like a kitchen wizard.

Optimal Cooking Time

Set your air fryer to 375 degrees Fahrenheit to achieve the perfect balance of crispy buns and juicy patties. Trust me, you're about to experience burger nirvana.

Now, before you toss those frozen White Castle sliders in, separate the bun tops from the patties. It might feel like you're breaking up a happy couple, but it's for their own good. This little maneuver ensures everything cooks evenly without one side feeling left out.

Pop the separated pieces into the air fryer basket. Now, here's the sweet spot: cook them for about 5-6 minutes. It's just enough time to scroll through Instagram, pretend you're working, or argue with your cat about why they can't sit on the counter.

After those glorious minutes, your sliders will be hot, melty, and crispy—basically perfection in a bite-sized form.

Air frying preserves the bun's texture and heats the patty and cheese to mouthwatering levels. Plus, you don't need to wrap them in foil like a fast-food mummy. So, ditch the microwave and embrace the air fryer—it's like giving your White Castle burgers a first-class upgrade.
