I absolutely love White Castle. I grew up eating them with my daddy, who also loved them. His passion for the little sliders, created my passion for the little sliders. I miss eating WC with him.
I’ve been known to go pick up a crave case randomly and keep them in the fridge for days warming up a few here and there. I’m telling you, it’s a thing. I can’t get enough of them. I’ve been wanting to try this recipe for a long time.

I’ve had this recipe written down on a recipe card forever. It came out of one of those community cookbooks which I adore. I did make a few tweaks and changes because I didn’t think the original would taste as similar.
Thankfully, I had all the ingredients to make them, so I gave them a shot.

How to Store Leftover White Castle Sliders
Cool Completely – Before you put them in the fridge, let the sliders cool down to room temperature. This helps keep your fridge from working too hard.
Wrap them up – Wrap each slider in aluminum foil. This helps keep them from drying out. Or if you have an airtight container, you can put the wrapped sliders in there for extra protection.
Refrigerate – Your sliders will stay good in the fridge for about 3 to 4 days.
How to Reheat White Castle Sliders
Oven: For the best results, reheat your sliders in the oven at a low temperature (around 325°F) until they’re heated through (about 5-10 minutes). This helps them get crispy again.
Microwave: If you’re short on time, you can use the microwave, but be careful not to overheat them, or they might get soggy.

If you haven’t tried a White Castle Cheeseburger Slider, this is a great recipe to do it.
Especially if you don’t live close enough to one to order some.

White Castle Cheeseburger Sliders Recipe

White Castle Cheeseburger Sliders
They taste exactly like the originals. Incredibly flavorful, covered in cheese and absolutely delicious.
Prevent your screen from going dark
- ¾ pounds ground beef
- 2 ounces [beefy onion soup mix]
- ¼ cup beef broth
- 1 cup beef broth
- 12 slider buns
- 10 slices american cheese thinly sliced
- 3 tablespoons onions minced
- 12 dill hamburger pickle chips
Preheat oven to 450 degrees F.
In a large bowl, mix together the ground beef, beefy onion soup mix and beef broth until well combined well.
- On a piece of parchment paper or wax paper, roll the hamburger meat out to about 1/4" thickness. Just keep rolling and make the meat into a rectangle shape. If you need to eyeball it, use the slider buns to size 4 across, 3 down – that's how big your beef patty should be when it's done. Remember that White Castle patties are quite thin. Now using a knife, cut into the meat where the slider buns will go making 12 distinct patties but keep them together as one large rectangle still, just make the cuts not fully separating them. Next, using anything that can make a decent sized hole, make 5 holes in each patty.
Place the meat in freezer for 25 minutes. It will not freeze but it should be a little bit easier to handle when it comes out.
In a large baking pan, pour 1 cup of beef broth and 3 tablespoons of minced onions and stir gently spreading the onions out evenly. Place the giant meat rectangle into the liquid. The liquid steams through the burgers and cooks them perfectly. Put in the 450 degree F. oven for 10 minutes.
Remove from oven after 10 minutes and drain all liquid from pan. (its ok for residual liquid to be there. Turn the meat out onto another piece of parchment paper.
On the baking pan, place the 12 BOTTOMS of the slider buns. Now gently turn the parchment paper back over placing the hamburger back on the buns. Using the cut marks you made as a guide, separate the burgers. Top with cheese slices, pickles and put the TOPS of the slider buns on.
Return to oven for 3-5 minutes, just long enough to melt the cheese. Serve immediately.
