Fast Food Sliders, Even Faster
This White Castle Slider copycat recipe is one of my very favorite party apps! Even my picky teenagers can’t get enough of them (and that’s saying something). Don’t let their small size fool you, these sliders are hearty, savory, and perfect for feeding a crowd. With less than 15 minutes of prep (and under an hour start to finish), you can have a big batch of homemade sliders ready to go. Try them with some Animal-Style Fries (yes, I know these are from a completely different fast food chain but a little crossover never hurt anyone), Tater Tots, or Fried Pickles. I know you are going to love these as much as we do!

Key Ingredients in White Castle Sliders
- Lipton onion soup mix – This comes in a two-pack in a box. It seasons the meat with a nice, savory onion flavor. You will only be using the dry mixture, so no need to make up the packet.
- Peanut butter – Yes, peanut butter! Just a tablespoon, and trust me on this! If you are really against using the peanut butter, you can just leave it out, but it holds the meat together nicely.
- Onion – Yellow onion that is finely chopped. You will scatter the onions over the top of the ground beef and bottom buns during the baking process.
How to Make White Castle Sliders Step-by-Step
- Mix the ground beef, Lipton onion soup mix, peanut butter, and milk in a large bowl. Spread the mixture on a half-sheet baking pan. Use a rolling pin to roll over the meat to smooth it out over the bottom of the baking sheet.
- Bake at 350 degrees for about 10 minutes. Take the pan out of the oven, sprinkle the diced onions all around the edges, then bake for 15 more minutes.
- Remove from the oven, spoon the onions from the edges all over the top of the meat, and layer with cheese slices. Bake another 7 to 10 minutes or until cheese has melted.
- Add the tops of the rolls (the bottom part of the rolls will just sit on the counter.) Bake for about 5 more minutes.
- Remove from oven. Slice the meat into individual sliders with a pizza cutter. Pick up the slider meat and its top bun with a spatula and set it on the bottom bun.
- Serve hot with mayo, ketchup, mustard, pickles, or any of your other favorite condiments.
What to Serve with Sliders
White Castle sliders pair perfectly with classic sides like Air Fryer Frozen French fries, Onion Rings, Tater Tots, or Sweet Potato Fries. Add a lighter touch with Coleslaw, a fresh side salad, or Easy Fruit Salad. For something heartier, serve them with Baked Beans, Homemade Mac And Cheese, or a warm bowl of Tomato Soup or our famous “Cheater” Chili.
Make Ahead and Storage Tips
You can easily make these White Castle sliders ahead of time or freeze them for later! Store cooled sliders in an airtight container in the fridge for up to 4 days, or wrap individually in plastic wrap and freeze in a Ziplock freezer bag for up to a month. Thaw in the refrigerator before reheating. When ready to enjoy, wrap in a paper towel and microwave for 30-40 seconds. They’ll taste just as fresh (and delicious) as the night before!
Frequently Asked Questions
Yes, of course you can, but I suggest giving them a try. Even if you don’t like onions, they add a wonderful flavor and texture that just can’t be duplicated.
I know it sounds weird, but the peanut butter adds a terrific texture and depth of flavor that is difficult to substitute. If you have a nut allergy or just can’t do the peanut butter, feel free to leave it out.
Yes! These work great and still have the classic onion flavor that helps provide the White Castle taste!

Ingredients
- 2 pounds ground beef
- 1 (2-ounce) packet Lipton soup mix
- 1 tablespoon peanut butter
- ½ cup milk
- 1 onion,, finely chopped
- 12 cheese slices, Kraft or Velveeta cheese slices work great too
- 12 slider rolls, I found mine in the bakery section of the grocery store. You may be able to fit more on depending on the size of the buns.
Instructions
- Heat oven to 350 degrees F. Set aside a half sheet baking pan.
- In a large bowl, mix together the ground beef. Lipton onion soup mix, peanut butter, and milk.
- Spread the meat mixture on the baking sheet. Use a rolling pin to roll over the meat to smooth it out. Bake for about 10 minutes. The meat will shrink. Put the diced onion all around the edges and bake 15 minutes.
- Remove from the oven, spoon the onions from the edges all over the top of the meat, and layer with cheese slices. Bake another 7 to 10 minutes or until cheese has melted.
- Add the tops of the rolls (the bottom part of the rolls will just sit on the counter.) Bake for about 5 more minutes.
- Remove from oven. Slice the meat into individual sliders with a pizza cutter. Pick up the slider meat and its top bun with a spatula and set it on the bottom bun.
Notes
- I found my slider rolls in the bakery section of the grocery store. You may be able to fit more or fewer buns on the meat, depending on the size of the buns.
- Once you have your cheese sliders baked and cut, you can top them with all kinds of toppings ketchup, mustard, mayonnaise, or other condiments; dill pickle slices (you’ll probably want 20-24 dill pickle chips for these, especially if you’re a fan of dill pickle); lime pickles; garlic powder; and a pinch of salt.
