It’s the Fourth of July! Let’s have a picnic on this patriotic holiday. I associate All-American hot dogs and hamburgers with Fourth of July celebrations and so I’m making burger sliders for this picnic. Mine are a re-make of White Castle sliders. These are miniature square hamburgers with onions served with a steamed bun. If you’ve never had a White Castle slider, try these substitutes. They are quite tasty little hamburgers.
White Castle is a family owned hamburger fast food chain found in the Midwestern states, so there’s a good chance you’ve never seen or tried these burgers. There are 420 chain stores vs McDonald’s 36,000 outlets according to Wikipedia. The sliders aren’t just any hamburger, White Castle followers find the sliders to be addictive.

The hamburgers are quite simple. They are ground beef patties seasoned with salt and pepper that are grilled. The distinctive features are the tiny chopped onions which are cooked along with the burgers adding flavor and the steamed buns. For my remake, I grilled the buns in margarine in a skillet to make a crispy, steamed bun.
Originally the patties were small balls (18 to one pound) which were placed on a grill. Slivered onions were added on top, the hamburger was flipped and pressed down. A bun was placed on top of the burger so that is was steamed and hot. A pickle was placed on top of the burger before serving. No other condiments were added; patrons could add their own ketchup, etc at the tabble. Now the burgers are pre-made and the onions are dehydrated ones. The burgers are flat and square with five holes poked in each square so the onions penetrate through.
White Castle now sells frozen burgers in stores throughout the states. A co-worker found some of their burgers at Sam’s Wholesale Club stores. I found some at Walgreen’s Pharmacy store. Now I have a source for my own White Castle burgers!
First fast food chain and first slider
The White Castle fast food chain was founded in 1921 in Wichita , Kansas. The chain claims to be the first fast food chain and the first to make sliders or tiny sandwiches. The company standardized the kitchen procedures making the process like an assembly line. To boost the public’s confidence in the sanitation of the food, all the building interiors were made of stainless steel and the workers wore spotless white uniforms.
The buildings are also easy to identify. They are made of pre-fabricated materials and look like a caste. Because it’s a family owned business and the all food products come from several manufacturing facilities (even the buns are family-made) the chain hasn’t grown outside the mid- west.
On one of our road trip travels through the mid-west, we stopped in Cincinnati. My son spotted a White Castle fast food chain restaurant. We had to try a burger. That was my in introduction to the sliders.
Re-make of a White Castle Slider
I searched the internet to find recipes for White Castle sliders. Of course there were many variations and I tried a number of these copy cat recipes. I found that if the burgers were too thin then all you tasted was the bun. If I grilled the tiny burgers, they burnt. If I used hamburger with a higher fat content, they were flavorful but too greasy.
In the end, I followed the process often found on the internet adding my own recipe and a few additional ingredients. Here are the ingredients for my sliders.
The hamburger ingredients of ground beef, salt, black pepper, egg and seasoned bread crumbs are mixed then rolled between wax paper to fit into a 8″ x 10″ baking pan.
Lots and lots of finely chopped or minced onion is generously layered onto the bottom of the pan.
Then the flattened ground beef is added on top of the onions. Holes are poked into the ground beef layer in the pan. I used a chop stick.
This is baked in a 400 degree oven for 15 to 20 minutes. Then the ground beef removed and cut 3 across and 4 down into approximately squares.
The final feature, which shouldn’t be omitted, is steamed buns. I used Pepperidge Farm slider buns. For extra flavor, I also grilled the buns.
I spread margarine on the open bun, placed the bun face down in a skillet and grilled on medium heat until the bun was browned. Don’t cook on high heat or the bun will burn.
Top with a dill pickle. Add other toppings if you wish. Yum. Great for a picnic along with my favorites — corn on the cob, potato salad and baked beans.
