“The absolute best recipe for make at home Whitey’s! Better than the “real” thing. If you don’t like’em, I’ll take your leftovers!” 😀 – Willie N.

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!

White Castle Sliders
Video
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.

Made these for my husband and myself while we watched the Super Bowl. Delicious! He couldn’t stop saying how much he was enjoying them!
Havng grown up in the Bronx, NY and going to White Castle often, I almost had my second son in White Castle on Castle Hill Ave. Having experienced giving birth to my first son, and not wanting to sit alone going through labor pains alone (that’s how it was in 1956) my husband and I sat at White Castle for coffee. My water broke and labor started. Living in Arizona for many years, whenever we visited relative in NY, the first stop was, that’s right, White Castle. That second son is crazy for White Castle and I always have them in the freezer. Thanks for the recipe, Mary BD
WOW! What a story! Thank you for sharing and we hope you love this recipe!
I made these on Saturday and they were addictive! My family begged me to make them again Monday. Absolutely delicious!
Many thanks for this awesome and easy recipie.
Super yummy! My guys raved about how delicious these sliders are, and even though I am not a fan of White Castle, these are so, so good. This recipe is really easy. Who knew peanut butter could enhance the flavor of a burger?
I know! I’ve started to see peanut butter burgers on the menu of a few local restaurants. I think White Castle really was on to something. Thank you for your comment. I’m so glad you enjoyed the recipe!
Did not taste like White Castle at all
Just reading the ingredients has my mouth watering. Simple directions and perfect to take as an appetizer.
This was so good! Tasted just like White Castle. Can’t wait to make these for family gatherings!
Could you make these on a flat top grill?
Sure!
What kind of peanut butter is used?
Can we use creamy Skippy or Jiff?
Use whichever creamy peanut butter you like best!
What size baking sheet is used in the video for this?
18″ x 26″
There is no peanut butter in the White Castle burger recipe
There used to be, but they took it out for allergy reasons. The original recipe has it!
This recipe is LEGIT! Made them for Super Bowl party – they were a HUGE HIT! I followed the recipe exactly and they came out great! I can’t wait to make them again!!! Thank you for the recipe!
I made these for the Super Bowl and they were a hit. I used ground turkey and rather than onions, I did pico (which I had just made). I loved how thin these were. I prefer thin over pub style thick sliders.
To add oomph, I added Mi Quang seasoning. Between it and the peanut butter, everyone was exceptionally pleased.
I could make these for my lunches in the future.
Thank you for fine-tuning and publishing the recipe.
Shame about the peanut butter. We have a peanut allergy in our home and can’t make this with the peanut butter. Yes we could make without but it sounds like from the comments it’s necessary.
There isn’t any peanut butter in the recipe, original or now. I’m in my late 40’s and managed one during college in Chicago (born and bread) and now they are required to disclose it for food allergy reasons.
Well I’m from Jersey, and I am 62. The original recipe had peanut butter in it. You’re 22 years behind me. Just because they took it out before you worked there doesn’t mean the original didn’t have it.
These sliders are so yummy and so easy to make! I highly recommend giving them a try!
This is so yummy and easy to make!
White Castle sliders are indescribably delicious. I know my family will not leave any leftovers. Yummy I love using the peanut butter. NO crumbs are left.
The Best 😋 My family loved them ( with the peanut butter)
These are really amazing! Loved the onions. 💕💕💕💕
I’ve made these about 20 times. My family is obsessed. These are the REAL DEAL. Idk what the peanut butter does but it’s necessary lol
These were DELICIOUS! The peanut butter may seem weird but it gives the sliders the authentic White Castle taste. Added some garlic powder before putting the cheese on and recommend the pickles on top. Will absolutely be making these again! Thank you!
I know it wouldn’t be a true White Castle slider, but could I sub turkey for the beef? Too weird?
