Step-by-Step Instructions
Prepare the Burger Patties
In a bowl, gently mix the ground beef with salt and pepper. Divide the mixture into four equal portions and shape them into patties. Press a slight indentation into the center of each patty to prevent it from puffing during cooking.
Sauté the Mushrooms and Onions
Heat butter and olive oil in a skillet over medium-high heat. Add the sliced mushrooms and onions, cooking for about 6–8 minutes until they are tender and golden brown. Season with salt and pepper, then set aside.
Cook the Beef Patties
Preheat a grill or skillet over medium-high heat. Place the patties on the hot surface and cook for 4–5 minutes per side, depending on your desired doneness.
Melt the Swiss Cheese
During the last minute of cooking, place a slice of Swiss cheese on each patty. Cover the pan or close the grill lid to allow the cheese to melt smoothly.
Toast the Brioche Buns
Lightly toast the brioche buns on the grill or in a skillet for about 1–2 minutes until golden and slightly crisp.
Assemble the Burgers
Place each cooked patty on the bottom half of a toasted bun. Top with the sautéed mushrooms and onions, then add any optional toppings you prefer.
Serve and Enjoy
Finish with the top bun and serve immediately while the burger is hot and juicy.
Recipe Notes & Tips
- Use High-Fat Ground Beef – An 80/20 blend provides the best flavor and juiciness.
- Don’t Overwork the Meat – Handle the beef gently when forming patties to keep them tender.
- Make an Indentation in the Patty – This prevents the burger from puffing up during cooking.
- Caramelize the Mushrooms Well – Allow them to brown properly for deeper flavor.
- Rest the Patties Briefly – Let the burgers rest for 2–3 minutes before serving to retain juices.
- Check Internal Temperature – Beef should reach 160°F (71°C) for safe consumption.

Sautéing mushrooms and onions in butter enhances their natural sweetness and creates deep umami notes that pair beautifully with the mild nuttiness of Swiss cheese. Toasted brioche buns provide structure and a buttery flavor that complements the rich fillings. The result is a well-balanced burger with savory depth, creamy melted cheese, and hearty toppings, delivering approximately 914 calories per serving.
