For the Caramelized Mushrooms and Onions
- 8 ounces cremini mushrooms, thinly sliced
- 1/2 yellow onion, thinly sliced
- 2 tablespoons unsalted butter
- 1 clove garlic, minced
- 1/2 teaspoon fresh thyme, chopped (or 1/4 teaspoon dried)
- 1/4 teaspoon kosher salt
- 1/8 teaspoon black pepper, freshly ground
For the Burger Patties
- 1 1/2 pounds ground beef, 80/20 lean
- 1 tablespoon Worcestershire sauce
- 1 teaspoon kosher salt
- 1/2 teaspoon black pepper, freshly ground
- 4 Swiss cheese, slices
For Assembly
- 4 brioche burger buns, split

- 2 tablespoons ketchup, as needed
- 1 tablespoon Dijon mustard, as needed
Instructions
- 1
In a large skillet or cast iron pan, melt the butter over medium heat. Add the sliced mushrooms and onions. Cook, stirring occasionally, for 8 to 10 minutes, until the mushrooms are tender and the onions are softened and lightly caramelized. Stir in the minced garlic, fresh thyme, 1/4 teaspoon kosher salt, and 1/8 teaspoon black pepper, and cook for another 1 to 2 minutes until fragrant. Remove from heat and set aside.

In a medium mixing bowl, gently combine the ground beef, Worcestershire sauce, 1 teaspoon kosher salt, and 1/2 teaspoon black pepper. Be careful not to overmix, as this can make the patties tough. Divide the mixture into 4 equal portions and form them into patties, about 3/4-inch thick, making a slight indentation in the center of each patty to prevent them from bulging while cooking.

Heat the same skillet or a separate large pan over medium-high heat. Add the burger patties and cook for 4 to 6 minutes per side for medium-rare to medium doneness, or adjust cooking time to your preferred level of doneness. During the last minute of cooking, place a slice of Swiss cheese on top of each patty, cover the pan, and allow the cheese to melt.

While the cheese is melting, lightly toast the brioche burger buns in a separate dry skillet or toaster until golden brown. This usually takes 1 to 2 minutes.

To assemble the burgers, spread mayonnaise, ketchup, and Dijon mustard on the toasted bun halves, if desired. Place a lettuce leaf on the bottom bun, followed by a tomato slice, then the cheesy burger patty. Top generously with the caramelized mushrooms and onions, and a few dill pickle slices. Place the top bun and serve immediately.
