What’s in the Gear List
Before you start cooking, make sure you have the following kitchen gear:
- Skillet or griddle: For cooking the burgers and sautéing the mushrooms and onions.

Stepwise Method: Mushroom Swiss Burger

Step 1: Prepare the Onions
In a large skillet, heat 2 tablespoons of olive or avocado oil over medium heat. Add the thickly sliced yellow onions and a pinch of salt. Sauté them for about 15-20 minutes until they become caramelized and golden brown. Stir occasionally to prevent burning.
Step 2: Sauté the Mushrooms
Once the onions are done, remove them from the skillet and set aside. In the same skillet, add the remaining 2 tablespoons of oil and the finely minced garlic cloves. Sauté for about 30 seconds until fragrant, then add the sliced mushrooms. Cook until they are tender and have released their moisture, about 5-7 minutes. Season with salt and pepper to taste.
Step 3: Cook the Beef Patties
While the mushrooms are cooking, form the ground beef into 4 equal patties, making a slight indentation in the center of each to prevent them from puffing up while cooking. Season both sides with coarse salt and freshly cracked pepper. In another skillet or griddle, heat over medium-high heat. Cook the patties for about 4-5 minutes on each side, or until they reach your desired level of doneness. Add a slice of Swiss cheese on top of each patty during the last minute of cooking to let it melt.
Step 4: Assemble the Burgers
