“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.
“I made these on Saturday and they were addictive! My family begged me to make them again Monday. Absolutely delicious!” – Lisa
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.

Love this recipe?
We want to hear from you! Please leave a review.
I made these tonight. Even my daughter who basically lives in plain pasta ate them and loved them. Thank you!!!
This was the WORST version of a standard White Castle slider I have made. Peanut butter?!? I tried this recipe with trepidation but proceeded in the name of science. If the OP actually has taste buds and has actually eaten a White Castle burger then they would never have released this abomination out to the public. I’m pissed and want my 1.5 lb ground beef back.
Sorry you didn’t like this recipe! We have found that others have loved it– what would you change about it?
Nice reply. You are a class act!
🙂
I guess there’s one in every crowd!
The recipe is great; family loved it and the peanut butter only adds to the creaminess.
Maybe it was the chef Joel and not the recipe that was the issue!
Oh the drama!!! They tasted great. Get over it.
Smelled great! I had just cheesed these glorious meaty lil beauties up put the tender onions on top and crowned the lil princesses up with a buttered kings hawaiian roll when my neglectful child minded **** girlfriend let my nephew reach into a 375°F oven i pushed him away before he made any contact and dropped all of my tasty sliders upside down in the oven… So i never tasted them… **** it tears families apart lol
Oh no! That is terrible! I’m so sorry!
Made these tonight, not exactly like a White Castle but still delicious, hubby loved them! Thanks, printing this recipe for sure!!
I am from Michigan but my hubby is in the Army and in a place where there are no white castles ????, luckily I came across this recipe and made them tonight, they were a huge hit, I will be making these again. ????
So happy to hear they were a hit!
I mince my onions and mix half of it in with the meat. Because I know that White Castle burgers are cooked with minced onions, I put a layer of them on the bottom before putting the meat on top of it.
When serving, add pickle chips. More authentic.
This was a great recipe! We used ground chuck, we used Velveeta cheddar slices and Sara Lee Hawaiian style dinner rolls. We were very nervous because White Castle cheeseburgers are our thing (NY)- we are now in NC and always crave WC- the frozen is not an option. Can I tell you- this recipe is SPOT ON! I wish I could share the picture- thank you for this recipe! It’s easy, simple ingredients and of course delicious!
Wow, I am so happy that you liked it! Thank you for taking the time to come back and let me know how you liked them! 😀
These are awesome!!! We think they are even better than the white castles and we love white castle. I have been asked for the recipe after a friend of ours stopped in right after they came out of the oven he couldn’t get enough of them.
Thank you for the recipe I will be making them again soon
Thank you, Colleen! I’m so glad you like the sliders!
What if you forgot the milk lol already in the oven
It will be ok! It should turn out just fine.
They were perfect, my problem was my own fault, my bread wasnt fresh and I don’t trust my oven 🙁 But the test is almost dead on.
This was really tasty! I used mayo instead of PB since we have an allergy in the house. My burgers were a little too thick, it made 9 instead of 12 but they were still totally cooked through using the stated cooking directions.
I did have to drain the liquids from the pan at about the 20 minute mark, there was soooo much liquid from all the onions and meat that it just had to be done.
I made a quick burger sauce using mayo, ketchup and sweet relish. Very tasty, ty for the recipe!
I made these a second time and improved the recipe to suit our tastes. What I did differently was I sauteed the onions on the stove to get them starting to caramelize. I like the flavor of onions cooked this way.
I added them to the meat then topped with the cheese and baked for the last 10 minutes or so, until the cheese was melted. This to me improved the taste. A side bonus was there was much, much less liquid on the pan while baking.
I made some of these, and they came out fantastic. I have a baking pan with a plastic cover, let them sit in the fridge in that pan over night, were even better the next day.
I did modify it a bit and use tahini instead of peanut butter.
Great idea using tahini– similar taste but probably not as sweet!
I tried this last night and it was muy bueno. I used oversized piece of parchment paper and poured off the fat each time I took out of the oven. Made the big patty about 1 1/2 inches bigger all around the dinner rolls and it shrunk down just right. Think you could do with 1 lb or 1 1/4 lb ground beef and know you only need 6 slices of American cheese or 12 slices Velveeta. Used American.
We love these, I have made them several times with great results. Who would have thought Peanut butter would taste so good in burgers.
I wonder what brand of peanut butter ppl r using. I use natural peanut butter and it has more of an earthy taste than say, Jiffy. I haven’t tried these yet but I’m torn between using mayo or PB.
We just use regular “Jiffy” type. You can certainly try the natural, but it might come out a little different than if you used the other kind
I used Jif natural and it was delicous.
These are delicious. I was’t sure about the Peanut Butter, oh my it does make this great! So easy to make. Thank you for a new recipe.
So glad you liked it! 😀
Well, I’ve tried many of these copycat White Castle Burger recipes over the past several years. And all of them were so-so at best…..until this one! Although I had to make some soft slider rolls as we don’t have them here in Western Australia, just BIG bready ones. (Oh, I’m American). And while its been about 10 years since I’ve had a WC, these were really really good. My wife, who’s Aussie, didn’t want to even try one until she saw them finished. LOVED them. In fact, I now have to make more on Thursday so she can bring them into her shop for her helper. THANKS!!
This recipe is not only delicious but fun! My granddaughters and I made an assembly line while constructing. The pb really makes this recipe. Thank you for such a wonderful recipe!
Thanks Jane! So glad you and your grandchildren had fun making them.
My family loved this but while they where eating it I told them the secret ingredient was peanut butter. ..all they could taste after that was the peanut butter and all was wasted so dont dare tell ur family the secret and they will love it.
Haha! Thanks for the warning!
Just came across this recipe from Pinterest, can’t wait to try it tomorrow! I grew up in Kentucky LOVING White Castle sliders! Just wanted to add that the chain uses Dusseldorf mustard, which in my opinion makes the whole thing. Just found it in my local grocery store for the first time marketed by White Castle, so these are on the menu tomorrow! Thanks!
Thank for the tip! I will have to look for that mustard.
