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.
