In-n-Out Sliders
Ingredients
1 package of @kingshawaiian Butter Rolls
1 or 2 lbs ground beef
1 1/2 teaspoon Kosher salt
½ teaspoon black pepper
8 slices american cheese
1 large white onion
Garlic Butter Bun Topping
½ teaspoon garlic salt
2 tablespoons butter, melted
In-n-out Sauce
1/2 cup mayonnaise
3 tablespoons ketchup
2 tablespoons sweet pickle relish
1 1/2 teaspoons sugar
1 1/2 teaspoons white vinegar
Directions
1. Preheat your oven to 375° and line your baking dish or tray with parchment paper. The baking dish should be the exact size of the amount of rolls you are using.
2. Season raw ground beef and press into parchment lined tray. This will make the ground beef into a rectangular shape once cooked.
3. Bake at 375° for 18-24 minutes or until juices run clear on top. 22 minutes with 2lbs of meat will be cooked to medium/medium well.
4. While the meat is cooking prepare your rolls and sauce, and grill your onions. Using a bread knife, cut all the rolls in half, creating a giant top layer and bottom layer. Do not separate the buns individually. Set aside and brush tops with butter mixture.
5. In a small bowl combine all sauce ingredients and refrigerate.
6. You can take this time to grill onions as well. I cut my onions into 1/2” thick slices (do not separate onions) and grilled them in 2tbs of salted butter and 1 tsp. of olive oil on medium heat until browned on both sides. (About 4 minutes total)
7. Once the ground beef has finished baking remove the pan from oven and carefully pull the parchment and burger from tray, draining the excess juice and letting it rest on a cutting board while you prepare the bread. I placed my cheese slices on at this point so they would melt with the heat of the meat. I then cleaned this baking dish so I could reuse it with my rolls.
8. Layer in a new piece of parchment paper and place your bottom half of bread in the dish. Carefully place your large burger patty on top of the rolls with a spatula. Layer with sauce and lettuce. Top with the final layer of buns.
