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!
- Mix – Mix the ground beef, Lipton onion soup mix, peanut butter, and milk in a large bowl.
- 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.
- Bake – Take the pan out of the oven, sprinkle the diced onions all around the edges, then bake for 15 more minutes.
- 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.
- Slice – Slice the cooked patties with a pizza cutter. Place the patties between the slider buns.
- 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
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!
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!

Ingredients
- 2 pounds ground beef
- 1 (2-ounce) packet Lipton soup mix (1 packet)
- 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 baking sheet.
- 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.
Be careful there’s a step missing from step 4 of the recipe as compared to the other instructions. (The onions need to be placed on top of the meat, add cheese.) Otherwise really yummy!
Thanks for catching that missing step! Somehow it got deleted! It is fixed now so we are all good. Thanks again for the head’s up!
I made the following modification to the recipe. After you cook the meat for the first 10 minutes; Step-1. It should be removed from the oven and the diced onions should be placed around the edges of the meat. Step-2. It should then be returned to the oven for an additional 10 minutes until the onions are cooked (Note: to make them less oily the onions could be simmered in water until tender, drained, and then used. Just remember to add an additional 5 minutes of cooking time to the meat the first time it is cooked). Step-3. The meat should be removed from the oven and the onions spooned into 12 small piles evenly spaced on the top. The cheese is then placed on top of the meat to completely cover it and the onions. It should then be returned to the oven and heated until the cheese melts, about 5 minutes. Step-4. Remove it from the oven and place the top half of the slider buns spaced evenly on top and return them to the oven for about 3 to 5 minutes to toast the buns. Step-5. Remove from the oven and cut the meat between the buns and place the sections on the saved bottom halves of the slider buns. Serve and enjoy. (Note: I recommend using a lean mix of hamburger)
Great tips!
Thank you for sharing this information for cooking 😇
I can’t wait to make these and surprise my husband with them. He LOVES the old fashioned Royal Castle burgers which are the same as the White Castle burgers.
I have another dumb question lol.. your recipe calls for 1 two oz packet of Lipton Onion Soup mix. However, the box says there is a total of 2 oz in the box, and 2 envelopes in there. So should I be using both envelopes for a total of two oz, or just one envelope? Is there maybe a different box that has one oz envelopes? I’ve used just 1 packet and it tastes fine, so it may be just a trivial thing.
Made these for my husband and myself while we watched the Super Bowl. Delicious! He couldn’t stop saying how much he was enjoying them!
