White Castle Sliders

This White Castle Sliders copycat recipe makes flavorful, juicy, perfect little burger bites! I remember eating them on a family trip to the East coast and could not get over how yummy they were! Since we don’t have any White Castle restaurants out West, I had to figure out how to make my own! After trying several recipes, I finally found this one on the Cooking With Carrie Blog and I made a few changes. They turned out perfect, exactly as I remembered. Enjoy this delicious restaurant favorite in the comfort of your own home.

Tips for the Perfect White Castle Sliders

  • Don’t be skeptical about the peanut butter that the recipe calls for. I know it sounds weird, but it adds a terrific texture that is difficult to substitute. It you have a nut allergy or just can’t do the peanut butter, feel free to leave it out.
  • Some readers have asked if you can leave out the onions. Of course you can, but I suggest giving them a try. The onions add such a wonderful flavor and texture that just can’t be duplicated.
  • These little sliders make the best leftovers! Pop them in the microwave for about 30-40 seconds and they taste just as fresh as the night before!
  • You can even freeze extra sliders for up to a month in freezer safe bags. Just make sure to thaw them completely in the refrigerator before microwaving, so they cook evenly.

White Castle Sliders you can make at home! If you’ve always wanted to replicate these popular burgers, this recipe is the real deal.
Prep Time 10 mins
Cook Time 40 mins
Total Time 50 mins
Course Appetizer, Dinner, Main Course
Cuisine American
Servings 12 Sliders



  • 2 pounds ground beef
  • 2 oz Lipton onion soup mix 1 packet
  • 1 tablespoon peanut butter (Yes, peanut butter. Trust me.)
  • 1/2 cup milk
  • 1 onion finely chopped
  • 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.
  • 12 cheese slices Kraft or Velveeta cheese slices work great too


  • In a large bowl mix the ground beef, Lipton onion soup mix, peanut butter, and milk.

  • Spread the meat mixture on a cookie sheet. Use a rolling pin to roll over the meat to smooth it out. Bake at 350 degrees for about 10 minutes. The meat will shrink. Take it out of the oven and put the diced onions all around the edges, this will give the meat a great flavor, and bake for 15 more minutes.

  • Remove from oven, then spoon the onions from the edges all over the top of the meat and layer with cheese slices. Bake another 7-10 minutes (until cheese is melted).

  • Remove from oven and add the tops of the rolls (the bottom part of the rolls will just sit on the counter) and place back in the oven for about 5 more minutes.

  • Take it out of the oven. Slice the meat with a pizza cutter and pick up the slider/top bun with a spatula and set it on the bottom bun.

How many stars would you give this recipe?


  1. I used premium ground beef and it seemed like there was an awful lot of liquid/grease, is it supposed to be that way? I poured some of it off because it just looked like it was drowning in grease.

    1. 5 stars
      After every step of taking the tray out of the oven, I gently lift one end of the tray and drain all of the juice into a solo cup or something I plan on discarding (Dont put it down the drain!). This method ends up draining a TON of liquid.

  2. 5 stars
    These were EXCELLENT, and a huge hit at our Slider Party. I searched a number of posts for “white castle burger recipes” and went with yours Erica. The only thing I did different was a I poked some holes in the meat after the first bake and spread the onions so they went into the holes too! Then, instead of adding the top bun and baking, I added the bottom bun on the meat and then set it on the top bun. Maybe I’m wrong, but I don’t remember the buns being toasted, I thought they were steamed. We’re having a huge pool party tonight with 40 people and I’m making these again! And of course serving them with crinkle cut fries! Totally not on my Weight Watchers points but I’m a runner so I’ll add an extra mile or two today and tomorrow!

  3. hi!! can i possibly spread the onions over the entire meat ‘slab’ (for lack of better words LOL) ? or do u feel it might be too much onion? i don’t mean a thick layer either!

  4. I am making them. So excited about this. I grew up in Michigan and now am in Northern California…

    I was so reluctant when I saw peanut butter in this recipe but I’m so glad we gave it a shot! I love love love this! We prepared it exactly as stated in the recipe and I’m so glad that we did! Delicious!

    Wow! Delicious! Was a hit with the family for Saturday Bloody Mary accompanyment!
    Total keeper recipe!

    omgoodness!! as a jersey girl growing up on these delicious bundles of joy. I followed your recipe and didn’t leave anything out including peanut butter( yea how weird is that) wow awesome!! can’t wait to eat the leftovers.

    1. We use a half sheet pan (18×13) and the sides are about an inch high. The photos you see in the recipe instructions are on a pan this size. I hope this helps!

    These were just ok. The peanut butter added a very weird flavor and if I were to make this again I would definitely leave it out.

  10. Tried this today…..as someone who lives in Columbus, Ohio, where the headquarters of White Castle is located and having consumed numerous sliders over the years, this was delicious. I can personally say that yes, these taste like White Castle sliders but BETTER. Thicker patty, extra onions, lotsa cheese-you must add dill pickles as they are an essential part of the little burgers. I am not sure what White Castle some of the reviewers have eaten at but true White Castle has NO condiments on them, none. No ketchup, mayo or mustard. They are simply bun, patty, onions and pickle, cheese options (American or jalapeño, sometimes garlic or smoky cheese are run as a special). For those who have sampled the frozen version, they are without pickle as they heat up to like surface of the sun hot. If you put dill pickle slices (dill relish works too) on them post nuking, that is the traditional burger. Highly recommend trying this as written-plus pickles! Enjoy!

    1. I worked in New Jersey for a year and the White Castles came with ketchup on them. It was the way they make them in Jersey. It was a long year.

    Very, very good, but not quite White Castle. I’m 72yo and have been eating WC since a toddler, I’ve often said “You can’t go into a White Castle as an adult and expect to survive!” As a young college student, my poor husband tried them and that’s when we found out he couldn’t tolerate onions. He’s gone now so next time I make this recipe I will cast aside fear and up the onion!!

    1. I haven’t tried that before, so I’m not sure. Ground turkey is usually a bit drier than beef so I don’t know if it would hold the shape as well. Let us know how it goes if you do try it!

    These are delicious! While they are not exactly the same as a White Castle burger, they do in a pinch. This is definitely a recipe I will make again and again. Thanks!

  13. 4 stars
    I haven’t had them but I want to know if I can freeze them.
    I definitely going to make them but there’s only two of us and I never have luck cutting the recipes

  14. 4 stars
    Wow this is really darn close and maybe better! But there is something missing even in the burp and the buns aren’t gooey. I will figure it out! The peanut butter is awesome you can’t really taste it but your mouth can feel it. Thank you for a White Castle burger in Florida!!!

    1. Do you think originally they buttered the buns ? Or maybe the grease from frying on a griddle saturated it?
