Bake Tater Tots according to package directions.
While tots are baking, prepare the hamburgers. In a small bowl, sprinkle seasoned salt onto ground beef and mix well. Divide meat and form into 2-3 burger patties.
In a medium skillet on medium heat, cook the burgers for 6-8 minutes per side, or until the internal temperature reaches 165°F and burgers are browned all the way through.
In a skillet with a small amount of olive oil, sauté onions and mushrooms.
Prepare the Cooper Cheese beer dip:
In a medium saucepan over medium heat, bring beer to a slow simmer. Add Cooper Cheese and stir until consistency is smooth. Or if you’re using premade Mason Jar Cheese Sauce, reheat sauce in a microwave-safe container and stir in your beer of choice.
Assemble your burgers:
Dollop the bottom section of each bun with a spoonful of Cooper Cheese Beer Dip. Place an optional lettuce leaf and slice of tomato over beer cheese dip, then top with a burger patty. Add a layer of sautéed onions and mushrooms. Top with about 5 Tater Tots, then add a generous drizzle of more Cooper Cheese Beer Dip. Cap each burger with the top of the onion roll, then serve and enjoy!
