Oven Baked Sliders

Oven Baked Sliders -These taste just like Krystal's or White Castle hamburgers. Super easy to make!

Here in the south, we have a fast-food restaurant called Krystal’s.  They are very similar to the popular White Castle hamburgers.  

We duplicated these little burgers at home.  They are the perfect finger food for a party or just a movie night at home.

Try our Roast Beef Sliders!

Oven Baked Sliders

hamburger meat patted into a square on a baking tray topped with chopped onions

Mix the ground beef with the onion soup mix.  Spread it as thin or thick as you prefer. We chose to make ours a little thicker than Krystal’s hamburgers. Spread the diced onions evenly on top of the meat.

Bake for about 15 minutes. (depending on the thickness)

Remove from the oven and place cheese slices on top.  Put back in for 3 – 5 minutes to melt the cheese.

Check out our Strawberry Shortcake!

Slice the dinner rolls with a serrated knife and place it on top of the cheese. Bake another 3 – 5 minutes.

It works best to slice with a large pizza cutter. Use a spatula to remove from the pan and place it on the bottom bun. Serve.

    These look delicious! I’ve planned on making these for the Superbowl. I do have a question though. Do they still taste good if they’re kept warm in a sterno? I’m a little worried about them drying out or the bread getting soggy. I figure they will be okay, because krystals warm up well. I just wanted to make sure.

      Hi, Terrance! I can’t really answer to how they will hold up in a Sterno. You could try placing a layer of paper towels to reduce condensation. I don’t think they will dry out. One recipe usually makes enough for us to have leftovers and they reheat beautifully. Thank you for coming by! 🙂

      I think paper towel on bottom but I prefer my bun a lil moist and lots of onions I layer whole bottom with onion and make a teepee to steam bottom bun a tad soggy 🤤🤤🤤

    If I want to reduce this to 1 lb. Of meat, do I need to reduce the bake time?

    1. Reply

      Yes, Jill I would reduce the baking time maybe to 10 minutes and just check the doneness. But make sure the onions are soft.

    OMG! Amazeballs!!! Made these for High School Baseball Team Dinner Friday night after practice. Boys devoured them!! I made 72 Sliders with 12lbs ground beef and we could’ve used about 2 dozen more, boy oh boy can those boys eat!! I omitted finely chopped onions, not knowing if boys would like the onions, but still used the onion soup mix for flavoring and added some salt. I also used Brioche Slider buns. This was the most straight forward recipe I found online. Thanks a million!!

    I know it’s none of my business but there’s this BBQ restaurant that is using the photos of the sliders and posting them to Facebook as if they are theirs. It didn’t seem right and I thought you should at least know about it. This is that post

    We skip the extra onion (toddlers) and do 1 lb of beef for our family of 4. A go-to for weeknight meal rotation. Thank you!

    I modify this recipe for my larger family and their tastes. But ALWAYS use this as a base.

    First time making sliders in the oven and I have to say that there is no way that I am going back to pan frying. I did not follow the ingredient directions to the T but these where amazing to say the least.

    these came out great, delicious and easy. I halved the recipe and it made 12 sliders but i didnt see the part about shortening the time and they still came out perfect. Thanks so much!!
