“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!

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.

We want to hear from you! Please leave a review.
Yum!! These are delicious! We had them for dinner tonight. My daughter, who says she does not eat meat, ate several of them then wrapped all the left overs in plastic to take to school tomorrow. They are the closing thing I have found to White Castle since I lived in New York 39 plus years ago.
Made this for game night! My boys loved them!!
Thank you for sharing.
Going to make these for my family for game day! Im excited! Wondering if you can use avacodo instead of peanut butter? Maybe I’ll try it both ways.
Yeah, I don’t know. We have only made it with PB. Let me know how it works out with avocado!
Ummmmmmm -the Midwest is NOT the East coast – we are the MIDWEST. Sliders are the product of a chain restaurant called White Castle. I lived long enough in the bay area to be amazed how little most residents are of the USA beyond the west coast.
I’m not sure why you are so upset. The White Castle burger I had was in New York.
What?! Surely you realized it’s a chain. It’s based out of the midwest. It’d be like saying you made In and Out in honor of Utahns. Sure they exist in Utah, but they aren’t FROM there! 🙂 Plus we Midwesterners tend to get disgruntled when others forget about us for the coasts. Frankly, it looks ignorant.
When I saw “East coast thing” I was confused as well LOL I grew up on White Castle in Illinois and Missouri, and they were actually founded in Kansas. It’s good to see they’ve branched out so far though, but I wish they had some in Texas! The ones from the freezer section at Wal-Mart aren’t even close! Thank you for the recipe Erica!
If I only use 1# of hamburger would I lower the other ingredients
How many sliders does this recipe make?
about 12-16.. depending on how big your slider rolls are.
Hi, what if I use turkey instead of beef? (I dont eat red meat) Will the peanut butter still be effective?
Haven’t tried turkey before… I don’t know how it will affect the taste/texture. Sorry! Wish I was of more help!
well maybe i made them wrong but i followed the recipe to the T
and it came out tasting like a peanut flavored burger drenched in onion soup mix
I don’t normally comment on recipe sites, but, every now and then something comes a long…
I made these for some coworkers the other night (Thursday), it is now Monday and I have made them seven times. The last two times were double batches. These are just outstanding!
And, I trusted you, the peanut butter really works and is also what intrigued me about them in the first place…plus I love the look on people’s faces when I tell them what the ‘secret’ ingredient is.
Thanks so much for sharing!
I am so glad you (and your co-workers) liked them! I always make them around this time of year because it is so much easier than making individual burgers. Thanks so much for the comment!
My husband made these last night and let me tell you how amazing these were! Thanks for the recipe
Loved these! However, instead of pushing bottom of buns to the side, I toasted them. Then I put mustard, ketchup, & a dill pickle chip on them. I did put mayo on some of them since I am a mayo person!
Easy to make. I’d cut back on the peanut butter a bit, but otherwise a great turnout. Used potato rolls.
I agree with this comment. A little too much of a PB undertone. But with this in mind, I will try to remake with half of it and see how it turns out. Thanks for the recipe.
These turned out absolutely amazing! Tastes just like the original…we added yellow mustard and pickles. If you like White Castle and/or Krystal, you’ve got to try this recipe!!
I’m going to try these even the pb ;o) I’ve been craving wc but the closest place is like an hour away. I even wrote wc and they aren’t going to put one here. My husband and I wanted them so bad back home for yrs but it was only 1/2 hr away to Indy or Greenfield to get them. But the yr after he passed away the finally built one in our town but I had moved to Ky. The ones in the store just aren’t the same either. So I’m going to try these instead. thanks for the receipe.
I made these for first time for my husband. I ended up using 2# hamburger. It ended up making them a little bit thicker. Still good. I was told I forgot ” pickles”. I was skeptical on the peanut butter as well. All turned out. Making them again tonight.
These were DELICIOUS and as close to White Castle as you can get. I did add a dill pickle chip and used Kroger slider buns….. I like the idea of dumping the grease after each step and will try that next time because I will make them again!
Gotta admit I was skeptical about these, having grown up in Brooklyn, New York where White Castle is plentiful. I decided to give these a try due to the fact that now I live in Southwest Missouri and can’t get them. Gotta say I’m impressed, they’re really good and pretty darn close. Kudos!!!!
Yummy
Tired this recipe today I don’t think you can get any closer to a white castle. Excellent
I also add the other half of the roll to the top bun ,cut side out . All parts are heated that way. Had a similar recipe for years. Like this recipe better..I think the peanut butter does it! Enjoy ♥
Could these be frozen?
Just curious what size cookie sheet? Is that a silly question? Very excited about this recipe though the peanut butter has me intrigued! My hubby loves White Castle I have never been because the closest one is about 60-70 minutes from here!
I think it is like 12×17 or 12×18. Just your typical size.
I use my biggest baking sheet I have so I have room to work. You’ll want the meat as flat as possible and it will shrink. Im unable to use my rolling pin due to how tall the sides are on my pan so I use the side of a cup or pat it down with my hands
