What You'll Learn

Preheat the air fryer
Preheating your air fryer is an important step in the cooking process, as it ensures even cooking and achieves a consistently crispy texture. The preheating temperature and duration may vary depending on the model and brand of your air fryer, so it is recommended to refer to the specific instructions for your device. However, as a general guideline, you can set the air fryer to a temperature between 350°F and 390°F and preheat for approximately 2 to 5 minutes.
During the preheating process, you can prepare the White Castle sliders for cooking. Start by removing the sliders from their packaging. If they are frozen, you can use a butter knife to separate them easily, especially if they are in a twin pack. Place the sliders in a single layer inside the air fryer basket, with the top of the bun facing down. You can also lightly toast the mini buns during this time if you prefer.
While the air fryer is preheating, you can also prepare the ground beef for the patties. Season the ground beef with salt and pepper, and spread it onto a baking sheet or pan. Press the meat down to form a thin patty, aiming for a thickness of about 1/8 inch. Use a fork to create small holes all over the patty, as this technique will help replicate the signature White Castle texture.
Once the air fryer has preheated to the desired temperature, you can place the sliders inside and start the cooking process. Depending on the model and brand of your air fryer, the cooking time may vary, so it is important to keep an eye on your sliders to ensure they are cooked to your desired level of doneness. For a guide, cook the sliders for around 8 to 12 minutes, flipping them over halfway through the cooking process.

Cooking spray for extra crispness
White Castle Sliders can be cooked in an air fryer and still retain their iconic taste and texture. The air fryer's ability to mimic the steam-cooking technique used by White Castle is what makes it perfect for this recipe.
To achieve an extra crispy exterior on the burgers, a light spritz of cooking spray can be used. This is an optional step, as the air fryer does a good job of crisping the burgers without the spray. However, if you want to add cooking spray, it is important to remember that too much can make the sliders greasy. A light spritz will do the trick.
The air fryer cooks with circulating hot air, ensuring a delightful bite without the excessive oil. This results in a healthier version of the famous White Castle Sliders. The cooking time may vary depending on the model and brand of the air fryer, so it is important to keep an eye on the burgers to find the perfect cooking duration.
- Preheat the air fryer to 370°F (188°C) and let it run for about 2-3 minutes.
- Remove the frozen burgers from their packaging.
- Lightly spritz the frozen burgers with cooking spray on both sides.
- Place the frozen sliders in a single layer in the air fryer basket, ensuring they don't overlap.
- Set the air fryer to 370°F (188°C) and cook for 10-12 minutes.
- Check the burgers at the end of the cooking time. They should be hot and crispy.
- If needed, add another 1-2 minutes, but watch closely to prevent overcooking.
- Carefully remove the sliders from the air fryer and serve immediately with your favorite condiments and toppings.
By following these steps, you can enjoy White Castle Sliders with an extra crispy exterior, thanks to the light spritz of cooking spray.

Cooking time and temperature
Cooking frozen White Castle Sliders in an air fryer is a straightforward process. However, there are some pro tips to elevate your sliders to the next level. Firstly, always preheat your air fryer to 370–375 °F (188 °C) for 2–5 minutes. Preheating ensures the burgers start cooking immediately, achieving a consistently crispy texture. It is also important to not overcrowd the air fryer basket. Cooking times may vary depending on the model and brand of your air fryer, so keep an eye on your burgers the first time you try this method.
When you are ready to cook, place 2–4 frozen sliders upside down in the air fryer basket. Set the timer for 10 minutes. Halfway through the cooking time, use tongs to flip the sliders and continue cooking for an additional 5 minutes until warmed through completely. Remove the sliders with tongs and serve immediately while hot.
If you are cooking multiple batches, you may need to reduce the cooking time by a few minutes. You can also separate the sliders first to avoid burning them. This is especially important for burgers with thick frozen meat patties. You can add about another 2 minutes to the suggested cooking time and adjust from there.
Some people prefer to thaw their frozen sliders in the microwave for 30 seconds before placing them in the air fryer. This helps to crisp up both the bun and the meat.
