Step 1
Preheat your oven to 375°.
Step 2
Take the white tray of buns out of the bag packaging (if using King's Hawaiian Rolls).
Step 3
Using parchment paper, unroll enough paper to make it the size of the tray that the rolls come in. Cut the parchment paper to the size of the tray of rolls.
Step 4
Set the tray of rolls aside and place raw ground beef on parchment paper and flatten to the size of the parchment paper.(Tip: Ground beef can "shrink" when cooking so if desired, you can spread/flatten it out a little over the edges to help it fit the buns, even if it shrinks!) This will make the ground beef a rectangular shape, when spread close to the sides of the parchment paper. NOTE: You're using the parchment paper as a guide to know what size to flatten the ground beef to so it can fit nicely on the rolls after cooking. If you prefer a thicker burger patty, you may want to use 2 lbs of ground beef, just know that it may have a longer bake time than instructed in the recipe card.
Step 5
Season ground beef with seasoned salt and pepper. (Amounts given in recipe card, or you can use your desired amount!)
Step 6
Now place parchment paper and ground beef rectangle in to rimmed baking sheet or cake pan.
Step 7
Bake at 375° for 15-17 minutes or until juices run clear on the top.
Step 8
While ground beef is baking, this is a great time to make the garlic butter and prep your rolls.
Step 9
In small microwavable dish, melt butter and then add in garlic salt. Stir to combine, and set aside.
Step 10
Using a bread knife, and keeping the sides of the 12 rolls connected... cut the rolls in half, long ways, creating a giant top layer and bottom bun layer. This way you can easily place the rectangle ground beef layer, once fully cooked, on top of bottom full layer of buns. (No need to try and build 12 individual sliders when it can all be done in one step.)
Step 11
Once the ground beef has finished baking (and juices are running clear) remove the pan from oven. (TIP: You can leave the oven on if you prefer, to toast buns in the next few steps.)
Step 12
Carefully, with a large spatula, pick up beef and tilt to drain excess grease back in to the pan.
Step 13
Then, place bottom layer of rolls, upside down on top of beef, and flip and transfer burgers to a clean baking sheet. This will result in the ground beef and bottom layer or rolls on the new baking sheet with the parchment paper facing up. (See images in blog post for tips!)
Step 14
Remove the parchment paper and throw paper away.
Step 15
Place 6 slices of cheese on top of ground beef. (we use American but you can use your favorite kind).
Step 16
Then, place the top bun layer on top of the cheese.
Step 17
Using a basting brush, brush the top of the buns with the garlic butter you have prepared.
Step 18
Place the baking tray of assembled sliders in a 375° oven, for 3-4 minutes or until cheese has melted and tops are golden brown.
Step 19
Optional: You can wrap the sliders in aluminum foil after coming out of the oven, so they will "steam" a bit.
Step 20
Remove from oven (careful, HOT!) and you can now cut the burgers in to sliders by using a pizza cutter (my favorite) or by cutting on the lines with a knife.
