Enjoy this delicious restaurant favorite in the comfort of your own home! Take your sliders to the next level with this simple and easy White Castle slider recipe. Layer the buns, meat mixture, and onions on top of each other to make the best tasting sliders yet!

Ingredients in White Castle Sliders

These aren’t your ordinary beef patties with cheese! You’ll love the unique flavor that results from combining the following ingredients:

  • Ground beef – Use lean ground beef for this slider recipe. A little fat from the hamburger in the meat is okay. It will hold the sliders together better.
  • 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.
  • Milk Gives the meat a tender and juicy texture.
  • 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.
  • Slider buns – I found mine in the bakery section of the grocery store. You can also use Hawaiian rolls in place of normal dinner rolls, or mini bread rolls.
  • Cheese slices – About 10 to 12 Kraft American cheese slices, or any type of cheese you like.

Step by Step Instructions

As I’ve already mentioned, these aren’t your typical cooked patties! It is a great meal to feed a crowd! It’s easy to make a lot of these sliders all at once using these step-by-step instructions. These white castle sliders come together quickly and easily!

  1. Mix – Mix the ground beef, Lipton onion soup mix, peanut butter, and milk in a large bowl.
  2. Flatten – Spread the mixture on a baking sheet lined with parchment paper. 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.
  3. Bake – Take the pan out of the oven, sprinkle the diced onions all around the edges, then bake for 15 more minutes.
  4. Layer – 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. 
  5. Slice – Slice the cooked patties with a pizza cutter. Place the patties between the slider buns.
  6. Serve – Add any condiments, pickles, or extras that you like over the patties, slap on the top buns, and enjoy!

Toppings for White Castle Sliders

Once you have your sliders baked and cut, you can top them with all kinds of toppings. Here are a few ideas to take your sliders to the next level!

  • Condiments – You can’t go wrong with the classics – ketchup, mustard, and mayonnaise.
  • Pickles – I prefer the dill pickle slices best, but you can try bread and butter or lime pickles for various flavors. If you are a pickle fan, then go crazy with the pickles. For us, we like to use about 20 to 24 dill pickles on our sliders.
  • Cheese – Choose your favorite cheese! American cheese will give you that signature flavor, but you can use cheddar, Swiss cheese, pepper jack, or Colby jack. Any cheese is good cheese when it is melty cheese!
  • Meat – Add on a slice of ham or cooked bacon strips for a thicker, more hearty slider.
  • Garlic powder – Sprinkle garlic powder on the burgers for some extra flavor.
  • Topping – Brush a little melted butter on top of the buns and add sesame seeds for a fun appearance and extra texture!

What to Serve with White Castle Sliders

These white castle sliders are delicious and filling by themselves, but for the authentic burger experience, we love to serve them with french fries. You can also enjoy them with a lighter side like salad or chips.

  • French Fries Classic crinkle-cut or shoestring fries make a perfect side to complement the sliders. You can make your french fries from scratch or cook up frozen fries in the air fryer!
  • Onion Rings Crunchy, golden-brown onion rings add a delicious texture and flavor contrast.
  • Coleslaw A creamy and refreshing coleslaw pairs well with the savory sliders, balancing out the flavors.
  • Side Salad A light side salad with fresh greens, tomatoes, and a vinaigrette dressing offers a healthier option.
  • Sweet Potato Fries – For a twist, serve sweet potato fries that provide a slightly sweet and savory contrast.
  • Chips – Crispy potato chips, whether regular or flavored, are an easy and convenient side option.
  • Fruit Salad A bowl of fresh fruit salad adds a refreshing touch to the meal, balancing the richness of the sliders.
  • Corn on the Cob Grilled or boiled corn on the cob can be a fun and flavorful addition to the meal.
  • Soup – Pair the sliders with a warm bowl of soup, such as tomato soup or a hearty chili, for a satisfying combination.
  • Macaroni and Cheese Creamy mac and cheese brings a comforting element to the meal.
  • Baked Beans – The sweetness and heartiness of baked beans complement the sliders’ flavors well.
  • Mashed Potatoes Creamy mashed potatoes are a comforting side that can be a great addition.

“This was so good! Tasted just like White Castle. Can’t wait to make these for family gatherings!”

Frequently Asked Questions

Can I leave out the onions?

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.

Why does this recipe call for peanut butter?

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.

Can I use pre-packaged dehydrated onions for the topping?

Yes! These work great and still have the classic onion flavor that helps provide the White Castle taste!

Storing the Perfect Sliders

Make these ahead of time or learn to freeze them the proper way! Store them for a quick snack the next day or freeze them for a later time. These white castle sliders are an easy weeknight dinner that everyone enjoys!

  • Making ahead – Prepare the sliders ahead of time and store them in the fridge until ready to reheat.
  • Storing – Place the cooled white castle cheeseburger sliders in an airtight container in the refrigerator for three to four days.
  • Freezing – Wrap the extra sliders in plastic wrap, then place in a freezer-safe bag for up to a month. Just make sure to thaw the burgers out completely in the refrigerator before microwaving so they cook evenly.
  • Reheating – These little sliders make the best leftovers! Take them out of the fridge and pop them in the microwave for about 30-40 seconds and they taste just as fresh as the night before!

  • 1 (2-ounce) packet Lipton soup mix (1 packet)
  • 1 tablespoon peanut butter
  • ½ cup milk
  • 1 onion, finely chopped

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.

    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!

  2. 5 stars
    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.

    1. Thank you for sharing your success with this recipe and your recommendations. I’m glad it was a hit!

  3. 5 stars
    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.

  4. 5 stars
    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!

    1. 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!

  5. 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.

    1. 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!

  7. 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!

    1. 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!

  8. 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.

        1. 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.

          1. You are right! If you order them w/everything they come with the Dusseldorf brown mustard! No ketchup or mayo is included w/everything.

  9. 5 stars
    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.

    1. Thank you so much for the tip! We will have to try it with buttermilk next time! Thanks for your comment!

  10. 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.

    1. 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!!

    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!!

    1. PS- We love Krystal burgers so much that we had tiers of them for my husband’s groom’s cake at our wedding. 🙂

  13. 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.

    1. 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!

  15. I can NOT find the Sara Lee Dinner Rolls 🙁 – I tried other rolls and it’s not the same – help!

    I’m a New York transplant in Texas. You literally just made my week. Thank you so much for this recipe!

  17. 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.

  18. 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.

    1. 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. 🙂

      1. 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.

    2. 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.
