Prepare the Burger Patties 🥩

1. In a large mixing bowl, combine the ground beef, Worcestershire sauce, steak seasoning, garlic powder, onion powder, salt, and pepper.

2. Mix gently with your hands until everything is well combined, being careful not to overmix to keep the patties tender.

3. Divide the mixture into four equal portions and form into patties about ¾ inch thick. Make a small indentation in the center of each patty with your thumb to prevent puffing during cooking.

Caramelize the Onions & Cook the Mushrooms 🍄🧅

1. In a large skillet, heat the butter and olive oil over medium heat.

2. Add the sliced onions and mushrooms (if using), and cook for about 10-12 minutes, stirring occasionally, until the onions are golden and caramelized and the mushrooms are tender. Set aside.

Grill the Patties 🔥

1. Preheat a grill or stovetop skillet over medium-high heat. Lightly oil the grill grates or skillet.

2. Place the burger patties on the grill and cook for 4-5 minutes per side for medium doneness, or until they reach an internal temperature of 160°F.

3. During the last minute of cooking, add a slice of cheese to each patty and cover to melt the cheese.

Toast the Buns 🥯

1. While the patties are cooking, lightly toast the buns on the grill or in a toaster until golden brown.

Assemble the Steakhouse Burgers 🍔

1. Spread a generous amount of steakhouse sauce on the bottom half of each toasted bun.

2. Place a lettuce leaf and a tomato slice on top.

3. Add the cheesy burger patty, then top with caramelized onions and mushrooms.

4. Add pickles, if desired, and top with the other half of the bun.

Serve & Enjoy! 🎉

1. Serve immediately with your favorite sides, such as fries, sweet potato wedges, or a crisp salad.

2. Dig in and enjoy the hearty steakhouse flavors!
