Do you love the famous Krystal and White Castle Burgers? What if you can make them at home, only better?
I have you covered with this Krystle Burger copycat recipe and White Castle Burger copycat recipe. These juicy mini burger sliders have the same signature onion flavor as the Krystle Burgers and White Castle Burgers.
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.
Once you make these, this Oven Baked Burger Sliders Recipe will be your new favorite dish for all of your parties!
Serve them on game day with Tennessee Onions and Old Fashioned Macaroni Salad for an AMAZING meal! I hope you enjoy! Xoxo~Katie.
Ingredient notes and substitutions
This is the list of ingredients you will need to make this easy cheeseburger sliders recipe.
- 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.
- Sweet Hawaiian Rolls-Substitute with any small slider buns.
- dill pickle chips-Use dill pickle slices over Kosher slices.
- ketchup
- mustard
- butter- real salted butter, not margarine
- Worcestershire sauce

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

Cooking Tips
- 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.
- 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.
- Rest oven burgers 5 minutes before serving. It gives it a chance for the flavors in the ground beef to circulate properly and helps maintain the juice.

I absolutely love these sliders and have made than many of times. Tonight I chopped a jalapeño and put in the bottom of the baking dish along with the onion before pressing the meat on top. So delicious!
Nikki says
These are a crowd pleaser! When ever I am invited somewhere I'm always asked to bring these sliders. They're delicious and what's great is if you're entertaining you do all the work before your company comes. Yum!
Lisa says
These sound amazing! I’m making these for Book Club tomorrow. Do you think I can make them all the way to putting the tops on but not “ dress “ them with the mustard sauce until tomorrow? Then just brush on the sauce and bake the last 20 mins? I don’t think they’ll get soggy- do you? Or maybe just make the meat today and assemble tomorrow? Thanks!! Very excited to try these! Lisa
Katie Crenshaw says
I would just make the meat a head of time. I do believe the buns would dry out or become soggy if you did it the night before.
Janet Baxley Hall says

Laura says
Just made these for the first time juicy delicious melted pepper jack instead of American with a sprinkle of shredded cheddar. Yum!
Allison says
Made this many times! I do 12 burgers ...thicker patty. Wonderful recipe!!!!
Kathy says
Have made these countless times. When bringing somewhere I wrap them individually in foil, warm them, and them put them in a thermal bag to keep warm. Great for parties. Thank you!!
Polly says
Will make these again! Recipe was on point!
Sydney says
Made these for a Jimmy Buffett tailgate party. I didn’t add any condiments because one of our crew doesn’t like anything on his burgers. I sautéed the onions for a few minutes and then put them on top of the ground beef. Everyone RAVED about them. No one even used ketchup, mustard or mayo on them. I made a double batch and they were gone!
Janet Sue Baxley Hall says
Sounds delicious! Definitely gonna try these.
Jason says
I have made these about four times since I found your recipe a few months ago. I usually cook with ground turkey instead of beef and the first time I made them, I accidentally got breakfast turkey sausage. They tasted so fantastic that I continue to use it. I also roll out the meat between wax paper instead of pressing it into the pan. I love onions so I use a large one and heap the cooked onions on top of the meat before adding the cheese. They are great reheated with an egg on top for breakfast also.
MJ says
How long did you cook the turkey burger for bs the ground beef? Same cook time? Thanks!
Jim Henderson says
These were excellent! Thanks!

Love this!! I bet your version tastes even better than the original!

I have never had one of the White Castle burgers, surprisingly, but I think I would prefer your versions because they look scrumptious!
Sandi says
