Instructions
How to Make Ultimate Mushroom Swiss Burger with Caramelized Onions
STEP ONE: Prepare the Onions
In a large skillet, heat the olive oil over medium-high heat. Add the thinly sliced onions and cook, stirring occasionally, until they become charred and caramelized, about 8-10 minutes. Stir in minced garlic during the last 2 minutes of cooking. Season with salt and pepper to taste. Remove from heat and set aside.
STEP TWO: Prepare the Mushrooms
In the same skillet, melt the butter over medium-high heat. Add the thinly sliced mushrooms and sauté until they are soft and browned, about 5-7 minutes. Season with salt and pepper, then combine the charred onions with the mushrooms.
STEP THREE: Prepare the Burger Patties
Shape the ground beef into 4 burger patties. Season both sides with onion powder, salt, and pepper. Heat a cast iron skillet over medium-high heat. Place the patties on the skillet and cook for 4-5 minutes per side. Make sure the internal temperature of the burger patties reaches a safe minimum of 160°F (71°C).
STEP FOUR: Assemble the Burgers
During the last minute of cooking the patties, add a slice of Swiss cheese on top of each patty and let it melt. Add a generous portion of the sautéed mushrooms and charred onions on top of each burger patty.
Toast the burger buns in the skillet or a toaster. Place each patty on the bottom half of the bun, cover with the top half, and serve immediately.

FAQ
A Mushroom Swiss Burger is unique due to its combination of sautéed mushrooms, melted Swiss cheese, and often caramelized onions, all layered on a juicy beef patty.
Yes, you can make a Mushroom Swiss Burger vegetarian by using a plant-based burger patty such as Beyond Beef or Impossible Burger. Additionally, you can substitute regular Swiss cheese with vegan cheese and use plant-based butter for sautéing the mushrooms and onions.
To caramelize onions, thinly slice a small onion and cook it in a skillet over medium-high heat with olive oil. Stir occasionally until the onions become golden brown and caramelized, which usually takes about 8-10 minutes. Adding a bit of salt can help draw out the moisture and improve the caramelization process.
