Printable recipe card at bottom of post.

Hi everyone and welcome to our site. We created this post a few years ago it was not planned, we were making White Castle Burgers for dinner and decided to snap a few last minute photos on our phone. But when I see this recipe photos I have to cringe a little… so I decided to keep the recipe as is, but I wanted to add a few updated photos. Yes I know it is a fast food recipe so who cares if it is pretty or not… but it just makes me feel better having a photo that is actually in focus, lol. Enjoy!

So many grew up on the famous White Castle burgers. They are even known as the first chain restaurant, initially reminding me of one of the best restaurants in Boston! So how do you make a White Castle Burger or “Slider“? It is quite easy and I will even show you an easy way to cook them up too so you get the nice thin patty of meat! And the best part out side of taste is that they are cooked in the oven! Yes cook your hamburger in the oven in 20 mins! The patties come out so nice and flat and are cooked perfectly on the onions!

Ingredients:

1 pound Hamburger – 80/20 is best
2/3 cup Onion – finely chopped
1 teaspoon Salt
1 teaspoon Black pepper
2 eggs
1/4 cup plain bread crumbs
1 package Dinner Rolls

Mix hamburger in bowl with black pepper, bread crumbs and eggs.

Thoroughly mix meat.

Finely chop onion and spread evenly over 13×9 baking pan.

Spoon portions of hamburger on top of onions. Evenly spoon meat around top of onions. Pat meat evenly on top of onions to cover entire pan. Then with straws poke holes close and evenly over entire meat. This allows the onion juice to rise through the meat, just as they do at White Castle.

Place in pre-heated oven at 400 F (bake) for 20 mins

Remove to add cheese if you want it- Place back in oven till cheese is melted – about 1-2 mins
Remove and cut into squares the size of your rolls

White Castle uses it's own technique for cooking the hamburgers. On top of the onions they add a thin, square 100% beef patty with 5 holes. On top of the patty they put the top and bottom of the square bun.

We invented the slider when we first took 100% beef and put it on top of grilled onions and a signature bun. Easy to heat, these satisfying Sliders are big in taste and in fun. Top them with dill pickles for a true White Castle experience.

The square patties fit the pans and cover them with just a bit of space between each patty. The put the bottom of the buns on top, and then the bun tops go on. The cooking onions produce steam and the buns cover the patty, capturing the steam. The end result is the burgers are steamed, not really fried.

White Castle's new method of cooking is to "steam" the burgers by resting them on a pile of onions, and the heat cooks the burgers via "onion steam."
