“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!

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.

We want to hear from you! Please leave a review.
These are amazing! Have been making them for about a year now and they get better every time! Great recipes and website. Thanks so much!
I just made these tonight and they were a huge hit. Taste just like the WC!!!!
So glad you liked them!!! Thanks for commenting!
These were awesome, I was a little skeptical on the PB but I made two batches one exactly as recipe calls and one with half the amount of PB I liked the one with half better, this may be because I use Natural PB. But these are a big hit. These are requested at parties and by my kids. Who by the way hate onions but do not question them on these burgers. Thanks for giving us the White castles anytime we want. Unless you have a PB Allergy you must try.
Thank you for sharing your success with this recipe and your recommendations. I’m glad it was a hit!
Awesome Recipe, I’ve used it several times. The one thing I would recommend to people is you may need to drain the grease in between visits to the oven. On that note its especially important NOT to use a flat cookie sheet; meaning with no sides. That’s a big first timer mistake.
These were absolutely fantastic!! My hubby is such a white castle fanatic and we do not have one where we live so this makes me wife of the year! 🙂
The only change I made was rehydrating some dried chopped onions and spreading those on the meat underneath the cheese instead of regular onions. I used the sweet hawaiian rolls. So darn good!
Thank you for this recipe, the peanut butter is a winner! This will be a repeat in my household!
GREAT idea rehydrating onions. That would make it way easier! I will definitely try that next time. So glad you liked the recipe! Thanks for your nice comment!
I’ve read almost all the conments. Several people asked about freezing them, but I didn’t see any reply. So can they be frozen? and if so, how long do you reheat them for and at what temp? And should they be reheated from fozen or thaw first? I would like to make these in advance of our get together but want to make sure they will turn out if frozen.
Please let me know asap.
You probably can freeze them but we have never done it before. I know they sell sliders in the frozen section at the grocery store so I don’t see why not! Let us know how it turns out!
Made these last night for my two picky eaters who seem to only like a few things to eat and my daughter doesn’t even like red meat but they at these. One a piece but at least they ate it because they usually eat much of nothing! So I would say these were a hit. My boyfriend even liked them and took the left overs to work!
This may seem like a stupid question. I’m wondering why would you cook the onions first around the edges of the meat and then after 10 min spoon all over the top of the meat and cook some more? Why not sprinkle the onion over the top of the meat to begin with? It would save a step. Does it make a difference with the flavor? Also, Do you not cook the bottom part of the rolls or do you stick those in the oven too? I have all the ingredients to make these tomorrow and I want to get it just right! We used to have White Castle in southern California a very long time ago and they were my favorite! I miss them so much and I’m super excited to try this recipe. Any responses would be appreciated!
It softens them up better when they are around the sides. You can add them over the top but they might get too dried out. You can cook the bottom of the rolls if you would like.. it’s not a bad idea. Usually we just serve them straight on the buns and they are wonderful!
I do a very similar thing using French onion soup mix. It gives both a beef broth and onion flavor punch in one.
PS: I now live in New Zealand so I have to resort to copycat recipes if I want the burgers.
Q:
Do W/C use pickles or ketchup or mustard?
I can’t remember and I want to recreate the exact burger.
Thanks.
From what I remember, they don’t… anyone else have thoughts on this?
Yes they have a pickle, and ketchup and mustard mixed
White Castle does not put condiments on their burgers… Just the onion and pickle (and cheese if you order cheeseburgers). Packets of Dusseldorf mustard, mayonnaise, and ketchup are available in the restaurants.
You are right! If you order them w/everything they come with the Dusseldorf brown mustard! No ketchup or mayo is included w/everything.
Served with one dill pickle. I always order extra pickles on mine
Awesome recipe, tasted pretty close to the real thing. I told a WC insider friend of mine this recipe, he winked and suggested butter milk.
I rushed home with some butter milk, made this again and it was spot on.
Thank you so much for the tip! We will have to try it with buttermilk next time! Thanks for your comment!
I actually didn’t like the peanut butter in these sliders. They were good overall buy I think I would do without that ingredient next time.
Thank you for your comment! We may have other viewers that feel the same way. They would taste just fine without the peanut butter.
Hi!!! OMG!! This was just delicious!!! Perfect recipe, I have tried several recipies trying to get something like white castle’s burgers and this one won the price!! As i live in Dominican Republic I did not find Sara Lee´s bread, but I got some local soft mini burger bread very alike! My fiance is a huge white castle fan and he loved them!!! I have I little blog myself (www.voguecuisine.wordpress.com), and I would like to share my intake on your recipe, and also post your link so every reader will know is of your authoring, are ok with it? Please let me know!
Doubled this recipe for our Super Bowl party this year, and they were a huge hit! We are from the South and currently live in NOLA. Our closest Krystal is on Bourbon Street…not exactly the area a local wants to venture to when a craving hits…so these were a very welcome find! They were easy to make although they do require some babysitting because you have to do a step every 5-10 minutes. Totally worth it, though, if these burgers are your thing. We added yellow mustard and dill pickles to make them more Krystal like, and we served them on Hawaiian Savory Butter Rolls. I plan on making them again for dinner tonight! My brother-in-law is allergic to peanuts, so we have decided to use a tablespoon of cream cheese or mayo in place of the peanut butter when we make it for him. Great recipe! Thanks for sharing!!
PS- We love Krystal burgers so much that we had tiers of them for my husband’s groom’s cake at our wedding. 🙂
That is so cool!
Unfortunately decided to make these last night for a party instead of using my trusted recipe… The peanut butter absolutely ruined my entire batch. My recipe is very similar but uses mayo and adds shredded cheddar to pan fried hamburger instead of milk and peanut butter. My recipe is MUCH MUCH better. Sorry…but this was barely edible.
Sorry you had such a bad experience with the PB… we have never had it be overpowering like that before. What brand of PB did you use?
I made these burgers this past weekend. OMG! They r soo good. Thanx so very much for the recipe! Even my 83 y/0 mother thought they were “delicious!” Cannot wait to make them again!:-) thanks again!
So glad you and your mom liked them!!! They are a favorite around here too!
I can NOT find the Sara Lee Dinner Rolls 🙁 – I tried other rolls and it’s not the same – help!
Yikes.. I don’t know what to tell you. Maybe King Hawaiian rolls?
I’m a New York transplant in Texas. You literally just made my week. Thank you so much for this recipe!
Better than White Castle. Thanks for the recipe.
I was hesitant to try this recipe because of the peanut butter. I’m so glad I did. They were excellent and I had to make two batches. Will definitely be making these again.and by the way, no one commented on the peanut butter so they must not have tasted it.
From someone who worked at white castles, this is not even close to the way the tasty little treasures are made. First you dont use lipton soup or peanut butter…not sure where that came from. What you do is you soak dehydrated onions in a pot of water until they are plump again. then you cover the bottom of a cookie sheet with the water and onions. (this is what gives the bread that soggy goodness) then you place your flattened burger patties then the bottoms of the buns go on top of the burger and then you place the top bun over the cracks between each bottom bun and the next bottom bun. They put in the over until done. thats it…its simple. Cheese goes on after they are done cooking and should not be completely melted like your pic shows. Tip it is better to use a covered stove top flat grill for these but the oven does just as good.
I’m sure it isn’t close to how they are made, but maybe it tastes similar to them? Did you try the recipe? I’d love to hear from someone who worked there if it tastes similar, even though it is made differently. 🙂
Yes, I agree. Erica didn’t claim that her recipe mimics the true W.C. recipe. However, the blend of these ingredients do create a very close similarity in taste&texture. Reminds me of the concept behind Mock Apple Pie. Who would ever guess that the secret apple filling, isn’t really apples at all- but rather, crushed and spiced up Ritz crackers?! As for this slider recipe, Lipton soup sounds a lot tastier and easier than rewetting dried up onions. Just sayin…Don’t knock it til you’ve tried it. Thanks so much for sharing Erica.
I think I may try it this way with the ground turkey because I can’t eat beef and I’m a little scared of the texture adding the peanut butter to turkey. May not have the same result.
