I have to say that sadly I have never had the opportunity to eat at a White Castle and sample the incredible sliders I hear so much about. I have purchased the frozen ones and thought they were pretty dang good.
I was shopping at my local bakery and they had the cutest little buns which inspired me to make Sliders! These turned out so delicious and tasty that I will be making them again and again for parties!
I checked out a few recipes online and this is what I did!
1/4 to 1/2 cup dried onion flakes
2 pounds ground chuck- 80/20 ground beef
1/2 t. seasoned salt
1/2 tsp garlic salt
1/2 tsp onion powder
Cheddar or Provolone Cheese (or whatever you like)
12- Small Sized Rolls
Evenly spread the onions on the bottom of a 9x13 inch baking dish or a jelly roll pan (which I used). Gently press the ground beef on top of the onion flakes. Press evenly making one giant pattie.
Sprinkle with seasoned salt. At this point you can use a drinking straw and poke holes throughout the meat. That is what they do with the original white castle sliders.
Bake in a 400 degree oven for 10 minutes, carefully remove from the oven and drain the excess oil off. If you have a big spatula I recommend turning the patty over.
Return to the oven and cook another 5 minutes.
Using a paper towel, pat the excess grease from the top of the pattie.
Sprinkle garlic salt and onion powder on the entire patty.
Cut into bun sized squares.
Slice open and separate each party roll. Place bottom of rolls on a large platter.
Using a spatula lift pattie with onion layer onto each bun bottom. Top each slider with a square of cheese and the bun top.
Microwave a bit until the cheese melts.
You can of course add the condiments of your choice. These re-heat very well the next day.
