Ingredients

FOR THE BURGER:

1 pound Ground Beef 80/20
2 tsp Avocado Oil
1 teaspoon Salt
½ teaspoon Black Pepper
8 slices American Cheese
1 Large Tomato sliced
1 White Onion sliced
8 Iceberg Lettuce Leaves
4 Hamburger Buns

FOR THE SAUCE:

¼ cup Mayonnaise
2 Tablespoons Ketchup
1 Tablespoon Sweet Pickle Relish
1 Tablespoon White Vinegar

Instructions

Form the ground beef into 4 balls approximately ¼ pound each.
Mix the sauce ingredients together in a small bowl.
Preheat the Blackstone grill over medium high heat (approximately 400 degrees F). Drizzle the avocado oil on the grill.
Place the buns on the preheated grill for 2 minutes to toast them and then set them aside while you prepare the beef.
Then place the beef balls on the Blackstone grill. Then top each one with a piece on parchment paper and firmly press down to smash the beef into a thin patty with either a burger press or a large spatula and then discard the parchment paper. Season the patties with salt and pepper.
Cook the patties for 2 minutes until the juices in the beef start to raise to the top and the color starts to change. Then scrape under the patty to get under the caramelized parts and flip the patty. Once flipped, do not smash down the patties again. Cook for 1 more minute and place 2 pieces of cheese on each of the patties. Cook for 1 more minute to allow the cheese to melt.
Then it’s time to assemble your burgers. Spread the sauce on the bottom of the bun. Then top it with the lettuce, tomatoes, patty and onions.
Then the burgers are ready to enjoy!

Notes

These burgers are best served fresh, but you can store the leftover patties in an airtight container for up to 1 week.

You can use any oil with a high smoke point for this recipe. We usually use avocado oil but canola oil, vegetable oil or coconut oil will work great too.
