Ingredients
Scale
- 2 pounds 80/20 ground beef
- Salt and freshly cracked black pepper, to taste
- 4 slices Swiss cheese (or more, to your preference)
- 4 hamburger buns, toasted
- 4 tablespoons olive or avocado oil
- 1 large yellow onion, thickly sliced
- 2 cups thinly sliced button or baby bella mushrooms
- 3 cloves garlic, finely minced
- 2 cups beef stock
- Optional: 1 teaspoon unsalted butter
- Optional: minced fresh parsley
Instructions
- Prepare the caramelized onions and mushrooms first: In a large skillet, heat 2 tablespoons of olive or avocado oil over medium heat. Add the thickly sliced yellow onion and cook slowly, stirring occasionally, for 10-15 minutes until deeply caramelized and tender. Remove onions from the pan and set aside.
- In the same skillet (no need to clean), add the remaining 2 tablespoons of oil. Increase heat to high. Add the sliced mushrooms, season lightly with salt, and sauté for 5-7 minutes until they are well browned and have released their moisture.
- Stir in the minced garlic and cook for about 1 minute until fragrant. Pour in the beef stock and bring to a simmer. Continue cooking over high heat, allowing the liquid to reduce by half and thicken into a luscious sauce. Season with salt and pepper to taste. If desired, stir in 1 teaspoon of unsalted butter and a sprinkle of fresh parsley. Keep the mushroom mixture warm.
- Form the burger patties: Gently divide the ground beef into four equal portions and form them into patties, about 1-inch thick. Season both sides generously with salt and freshly cracked black pepper.
- Cook the burgers: You can grill or pan-fry the patties. Cook over medium-high heat for 4-5 minutes per side for medium-rare, adjusting time for desired doneness. During the last minute of cooking, place a slice of Swiss cheese on top of each burger and allow it to melt.
- Assemble the burgers: Place a cooked, cheesy burger patty onto a toasted bottom bun. Layer generously with the caramelized onions, followed by a spoonful of the warm sautéed mushrooms and their sauce. Crown with the top bun and serve immediately.
