Ingredients

• 2 tablespoon unsalted butter
• 4 hoagie buns
• 1 1/2 teaspoon sea salt
• 3/4 teaspoon black pepper
• 1 1/2 lbs ground chuck (15% fat)
• 1 medium yellow onion (diced)
• 8 slices American cheese (or favorite cheese)
• 1/4 cup mayonnaise
• 2 cups shredded lettuce
• 8 slices tomatoes

Augmentations

• Saute the onions and mix them into the ground beef

Instructions

Step 1

Dice yellow onion, slice tomatoes, and shred lettuce. Set aside until needed.

Step 2

Spread 1/2 tablespoon of butter on the inside of each hoagie roll. Grill in a large skillet until golden brown. Plate until needed.

Step 3

Divide the meat into four 6-ounce portions and shape each portion into an oval. Season generously on both sides with salt and pepper. Place one portion into a hot cast-iron skillet and smash with the back of a spatula (similar to smash burgers). Cook over medium high heat for a few minutes.

Step 4

Flip the flattened patty to the other side and top with a quarter of the diced onions. Now begin chopping the burger patty as you mix in the onions. Continue doing this for a few minutes until the meat has crispy edges and the onions are grilled.

Step 5

Top meat with 2 American cheese slices. Turn off the heat and allow the cheese to melt.

Step 6

Slather mayo and ketchup on the toasted hoagy roll. Add the patty and top with shredded lettuce and sliced tomatoes. Season with salt and pepper and serve.

Notes

• The sandwich needs to be wrapped in parchment paper to lock in flavor.
• Onions can be grilled if you desire.
