Sometimes, you just want to enjoy some fast food burgers without having to leave the house. Skip the delivery fees and learn how to cook frozen White Castle burgers in the microwave instead! That’s right, these yummy burger sliders go straight from freezer to delicious in minutes!
Sometimes, you’re just not able to get out of the house. We’ve all been there. Instead of missing out on your favorite fast food, though, you can reach for that box in your freezer! These White Castle sliders taste almost like the real thing.
They come in classic burger slider, cheeseburger slider, and even breakfast slider forms, with sausage, egg and cheese. Not only can White Castle be a great way to start your day, but they’ve got lunch covered too.
Of course, you can always make your White Castle Sliders in the Air Fryeras well. However, if you don’t have an air fryer (yet) or need them ready in even less time, your microwave is your friend!
What You’ll Need
Frozen White Castle burger sliders (or any other flavor you like)
Condiments if desired (optional)
Additional toppings (optional)
Ingredient Tips and Substitutions
White Castle burger sliders are usually available in quantities of 6 or 16 frozen, though sometimes you can find larger quantities at a Sam’s Club or similar store. A serving is 2 sliders, so grab as many as you need based on how many you’re feeding!
Note that you can substitute cheese sliders, jalapeno cheese sliders, or chicken sliders instead of the original plain burger. However, chicken sliders take about 10 seconds longer and cheese sliders require about 20 seconds longer to cook than original (in a 1000W microwave)
For additional toppings, I always recommend adding pickle slices, as the frozen version does not come with pickles like you’d get in the restaurant. That is, unless you get the White Castle jalapeno cheese sliders, which I think are flavorful enough on their own
You can also add any other toppings or condiments that you’d normally put on a hamburger, if you’d like
