Featured with this recipe
This White Castle Sliders copycat recipe makes flavorful, juicy, perfect little cheeseburgers. I remember eating these sliders on a family trip to the East coast and could not get over how yummy they were. I found myself craving them all the time. Since we don’t have any White Castle restaurants out West, I had to figure out how to make my own menu favorite. After trying several recipes, I finally found this one on the Cooking With Carrie Blog. A couple of little tweaks later, they turned out perfectly, exactly as I remembered. Enjoy this delicious restaurant favorite in the comfort of your own home.
Ingredients in White Castle Sliders
These aren’t your ordinary beef patties with cheese. You’ll love the unique flavor of this delicious ground beef mixture and toppings. Here’s what you need:
- 2 pounds lean ground beef – I like to use lean hamburger but you want a little fat in the meat so it’ll hold together.
- Lipton onion soup mix – 1 packet or two ounces
- 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 really holds the meat together nicely.
- Milk – about half a cup
- 1 medium yellow onion – finely chopped
- 12 Slider Rolls – 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 10-12 Kraft American cheese slices, or any type of cheese you like. American cheese will give you that signature flavor, but you can use cheddar, Swiss, pepper jack, or Colby jack.
Step by Step Instructions
These aren’t your typical cooked patties. It’s actually easy to make a lot of these sliders all at once, following these simple steps:
- First, mix the ground beef, Lipton onion soup mix, peanut butter, and milk in a large bowl.
- Next, 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.
- Then, take the pan out of the oven and sprinkle the diced onions all around the edges 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).
- Finally, slice the cooked patties with a pizza cutter and pick up the slider/top but with a spatula and set the patty on the bottom bun.
- Add any condiments, pickles, etc. that you like. And enjoy!
Toppings for White Castle Burgers
Once you have your sliders baked and cut, you can top your cheese slider with all kinds of toppings:
- Ketchup, mustard, mayonnaise or other condiments.
- Dill pickle slices – you’ll probably want about 20-24 dill pickle chips for these, especially if you’re a fan of dill pickle.
- Lime pickles
- Garlic powder
- Pinch of salt
What to Serve with White Castle Sliders
- French Fries: Classic crinkle-cut or shoestring fries make a perfect side to complement the sliders. You can make your own 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.
Frequently Asked Questions about White Castle Sliders
Yes! Store extra sliders 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.
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.
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. If you have a nut allergy or just can’t do the peanut butter, feel free to leave it out.
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!

- 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
Instructions
- 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.

There is no peanut butter in the White Castle burger recipe
There used to be, but they took it out for allergy reasons. The original recipe has it!
This recipe is LEGIT! Made them for Super Bowl party – they were a HUGE HIT! I followed the recipe exactly and they came out great! I can’t wait to make them again!!! Thank you for the recipe!
I made these for the Super Bowl and they were a hit. I used ground turkey and rather than onions, I did pico (which I had just made). I loved how thin these were. I prefer thin over pub style thick sliders.
To add oomph, I added Mi Quang seasoning. Between it and the peanut butter, everyone was exceptionally pleased.
I could make these for my lunches in the future.
Thank you for fine-tuning and publishing the recipe.
Shame about the peanut butter. We have a peanut allergy in our home and can’t make this with the peanut butter. Yes we could make without but it sounds like from the comments it’s necessary.
There isn’t any peanut butter in the recipe, original or now. I’m in my late 40’s and managed one during college in Chicago (born and bread) and now they are required to disclose it for food allergy reasons.
These sliders are so yummy and so easy to make! I highly recommend giving them a try!
This is so yummy and easy to make!
White Castle sliders are indescribably delicious. I know my family will not leave any leftovers. Yummy I love using the peanut butter. NO crumbs are left.
The Best 😋 My family loved them ( with the peanut butter)
These are really amazing! Loved the onions. 💕💕💕💕
I’ve made these about 20 times. My family is obsessed. These are the REAL DEAL. Idk what the peanut butter does but it’s necessary lol
These were DELICIOUS! The peanut butter may seem weird but it gives the sliders the authentic White Castle taste. Added some garlic powder before putting the cheese on and recommend the pickles on top. Will absolutely be making these again! Thank you!
I know it wouldn’t be a true White Castle slider, but could I sub turkey for the beef? Too weird?
Giving this 3 stars as it was ok! However I wanted to follow the recipe to a T for the first time and the peanut butter was just way too overpowering. Even adding relish and ketchup I couldn’t get the taste of PB out of my mouth (over other flavors). Next time will omit 🙂
Feel the same way. For some reason I taste it in every bite. Might cut it down to half next time
