Oklahoma Onion Burger Recipe: A Classic Diner Delight

Ingredients

• 2 tablespoons salted butter
• 1 tablespoon olive oil
• 1 large onion, very thinly sliced
• 0.5 teaspoon granulated garlic
• 1 pound 85% lean ground beef
• 0.5 teaspoon salt
• 1 teaspoon Hamburger Seasoning
• 0.5 cup sliced portobello mushrooms
• ground black pepper to taste
• 4 slices Swiss cheese
• 4 rolls rolls, hamburger, white, enriched, plain

Instructions

1. Heat a skillet over medium heat. Add butter and oil; heat until butter is melted. Add onion and garlic. Cook until onion is soft and translucent, about 5 minutes.
2. Meanwhile, divide ground meat into 4 portions and shape into patties. Season with salt and seasoning.
3. Heat a large skillet or flat-top over medium-high heat for a few minutes. Place patties into the hot skillet and smash with a spatula or bacon press. Hold patties down for 30 seconds, then cover each patty with some of the cooked onion. Cook for 2 minutes. Carefully flip burgers, making sure to scrape the browned bits off the skillet.
4. Press down on the flipped patties to sink the onions into the meat.
5. Meanwhile, add sliced mushrooms to the skillet used for the onion and cook until softened, about 5 minutes.
6. Season patties with salt and pepper and place a slice of cheese on each. Cook until burgers have reached the desired doneness, 2 to 4 minutes more. Top each patty with leftover onion and mushrooms and serve on buns.
