What makes them so good

What makes these mini burgers better is that I add in tons of cheese, and serve them on Hawaiian rolls that are topped with a butter glaze.

After all, what is more fun than eating a slider?

Especially a juicy, flavorful, cheeseburger slider. YUUUMMMMMM!!!!!

Ingredients

This is the list of ingredients you will need to make baked burger sliders.

• white onion- You will want to finely chop into tiny pieces.
• 80/20 ground beef- the fattier ground beef will make the burgers more juicy and flavorful.
• seasoned salt or regular salt
• American Cheese- You can substitute for cheddar, but to taste similar to a Krystal or White Castle burger, you will want American cheese. It melts creamier.
• Hawaiian Rolls
• dill pickle chips
• ketchup
• mustard
• butter- real salted butter, not margarine
• Worcestershire sauce

Steps

Making these oven burgers takes a little work, but it is worth the effort and easy to do.

Follow these steps on how to make oven burger sliders:

1. Finely dice a small onion. Evenly sprinkle the onions on a 9x13 inch baking dish.
2. Gently pat ground beef over the onion. Press evenly making a giant hamburger patty.
3. Next poke small holes in the meat. I use a straw.
4. Evenly sprinkle seasoned salt over ground beef.
5. Next bake the meat in the oven at 400 degrees for 20 minutes.
6. Cut into ground beef into squares with a pizza cutter.
7. In a 9x 13 casserole pan, cut a huge piece of foil big enough to cover whole pan. Add bottom of Hawaiian rolls over the foil. Top each roll bottom with a hamburger patty.
8. Divide each American cheese slice into 4 pieces. Add 2 slices on each burger.
9. Top each burger with pickles.
10. Add ketchup and mustard to each burger.
11. Melt butter and mix with Worcestershire sauce and mustard.  Add Hawaiian roll tops on each burger. Then lightly brush butter mixture on top of each bun.
12. Cover with tin foil and bake for an additional 20 minutes or until cheese is completely melted. Serve!

NOTE: It is really important for the onion to be finely chopped. This allows the onion to evenly distribute into the patties. You don't want overwhelming big chunks of onion when you take a bite.

Important Tips

Here are some tips to help you make the perfect oven baked burgers.

• Use 80/20 ground beef. This will make your burgers juicy. You can use 85% lean ground beef, but I would not suggest 90%. At 90%, your baked burgers may turn out dry.
• Drain all excess fat and liquid!!!
• If you really want to have a Krystle and White Castle Burgers Copycat, use the American cheese. Real cheddar cheese is great on these oven baked burgers, but it melts differently than the American cheese.
• Cover your pan with tin foil when you bake your burgers in the Hawaiian Rolls. This will steam the buns.
• If you don't cover with foil, the buns become hard.
• If you want to lightly crisp the tops of the buns, you can remove the foil on the last 5 minutes.
• I like to have my burgers rest 5 minutes before serving. It gives it a chance for the flavors in the ground beef to circulate properly and helps maintain the juice.
• Use dill pickle slices over Kosher slices.
