Copycat Recipe for White Castle Burgers
Somewhere hidden between the bun, the beef, and the American cheese is a secret flavor that makes White Castle sliders irresistible. But while we might want to, most of us don’t run to White Castle every time we have a craving. (Surprise! Fast-food isn't too healthy!) Thankfully, we have tricks up our sleeves for recreating childhood classics at home with fresh ingredients without sacrificing any flavor. Whether you’d just like to make the classic slider, or want to turn it into an edible, you’re in the right place. Keep reading for our recipe for White Castle burgers to satisfy your nostalgic taste buds.
Why White Castle Sliders Taste So Good
White Castle didn't just invent the slider—they are America’s first fast-food burger chain. Since opening in 1921, White Castle has accumulated some effective tricks to mastering the perfect, quick, reliably delicious slider. So, what are their secrets, and can they be recreated at home? The short answer is: there are many secrets, and they can all be done from your kitchen. Rejoice!
Secret #1: The Patty
White Castle flattens their patty until it’s crazy thin, then quickly sears both sides to keep that beef as tender and moist as possible. In this recipe, we replicate that process by using a rolling pin to flatten out the beef, and popping it in the oven. Sounds odd? Don’t question it. Embrace the copycat White Castle process.
Secret #2: The Onions
White Castle cooks their burgers and buns over a bed of onions, which gives the beef that intense flavor. The reason being, as the onions cook, they create flavorful onion steam, which rises up into the burger. This way, every bite is imbued with onion flavoring. In this recipe, we simulate this process by surrounding the beef on the cooking sheet with onions. It’s pretty darn good.
Secret #3: The Square Shape
White Castle pioneered the practice of cutting beef patties into square blocks, mainly for efficiency purposes. But, the practice is also to ensure every bite of slider contains patty and bun (the buns are also square). It also looks cool. In this recipe, we keep the patties square, even if just to preserve that nostalgia.
Secret #4: Steaming The Buns
There’s a reason White Castle sliders kind of resemble pork buns when you squint—they are steamed! To get that flavorful onion goodness throughout the slider, White Castle steams the buns on top of the burgers. In this recipe, we pop those buns in the oven with the beef in the final five minutes of baking.
Secret #5: Peanut Butter
Okay, hear us out. We found this ingenius recipe from Fav Family Recipes that calls for peanut butter, and it’s kinda magical. Apparently, the peanut butter unites all the flavors in the slider, and keeps the consistency perfect as it bakes. We tried it ourselves, and it works! So, don’t skip the peanut butter. Unless you have an allergy, then by all means, please skip it.
How To Elevate Your Slider
If you’re pumped to get started with your classic White Castle slider, scroll down to the recipe! But, if you’re looking for instructions on how to turn your slider into an edible, you’re in the right place.
At LĒVO, we’re all about simplifying the herbal infusion process, so you can make your meals more flavorful and your edibles more fun. Who wants to buy a brownie edible made in a factory, when you could make your own? The same goes with other creative edible ideas. Why not turn your White Castle slider into an edible?
The basic idea here is to infuse flower (*wink* you know what we mean, right?) with a liquid base, and then add the infusion to your recipe. In this case, we infuse flower directly into the milk that the recipe calls for! If you’re sitting there, scratching your head, thinking, “How in the world am I going to infuse flower into milk?” we gotchu.
Infusing Flower Into Milk
While it’s entirely possible to do this on your own with a cooking sheet, a cooking pot, and a cheese cloth, there’s always the risk of burning the house down. Plus, it’s super messy. LĒVO, the innovative kitchen device, simplifies this infusion process. All you need to do is pour your milk directly into the machine with your flower, and press a button. For more detailed info on how to infuse milk with LĒVO, click here.

Without further ado, let’s get cooking! Quick reminder, if you don’t want to make edibles, just skip the Infusion steps. Enjoy our recipe for White Castle burgers—we promise your sliders won’t last long!

Coarse or finely ground flower
16 oz (2 cups) full-fat milk (vegan substitute: full-fat coconut milk)
2 lbs ground beef
2 oz Lipton onion soup mix (1 packet)
1 Tbsp peanut butter
1/2 cup milk
1 onion, finely chopped
12 slider rolls
12 American cheese slices
Fill LEVO Herb Pod with flower.
Set LEVO to default Activate setting at 240°F for 30 minutes.
Once complete, add milk to the LEVO reservoir.
Set LEVO to Infuse at 150°F for 30 minutes. Do NOT heat your milk over 165°F.
Once complete, dispense into an airtight glass container.
Set aside ½ cup of flower-infused milk for this recipe.
Preheat the oven to 350°F.
Mix together the ground beef, peanut butter, infused milk, and onion soup mix in a large bowl.
Pour the mixture onto a cookie sheet and use a rolling pin to smooth out the meat.
Pop the cookie sheet into the oven and bake for 10 minutes.
Remove from the oven. The meat will have shrunken a bit. Add the diced onions around the edges of the meat.
Pop the cookie sheet back into the oven and bake for 15 more minutes.
Remove the oven. Move the onions over the top of the meat, then add cheese slices to each slider. Bake for another 10 minutes (or until the cheese is melted).
Remove from the oven and add the top of the rolls to each slider. Keep the bottoms of the rolls on the counter. Bake for another 5 minutes.
Remove from the oven, and slice the meat in a grid pattern. Then pick up the sliders with a spatula and add them to the bottom buns.
