I have always loved making these mushroom Swiss burgers for friends on weeknights, and adding waffle fries makes the meal feel extra special. It's a simple preparation, yet feels restaurant-worthy every time.
Ingredients
- Ground beef (80/20 blend recommended): 1 lb (450 g)
- Salt: 1 tsp
- Black pepper: ½ tsp
- Worcestershire sauce: 1 tbsp
- Olive oil: 1 tbsp for burgers, 1 tbsp for fries (if baking)
- Cremini or button mushrooms, sliced: 8 oz (225 g)
- Onion, thinly sliced: 1 small
- Swiss cheese: 4 slices
- Burger buns: 4
- Mayonnaise (optional): 2 tbsp
- Dijon mustard (optional): 2 tbsp
- Baby arugula or lettuce leaves: 1 cup
- Frozen waffle fries: 1½ lbs (680 g)
- Salt, to taste: for waffle fries
Instructions
- Prepare the Fries:
- Preheat the oven to 425°F (220°C). Arrange waffle fries on a baking sheet in a single layer. Drizzle with olive oil and bake for 22–28 minutes, turning halfway, until golden and crisp. Season with salt.
- Mix and Shape Patties:
- Combine ground beef, salt, pepper, and Worcestershire sauce in a bowl. Gently mix and form into 4 equal patties, slightly larger than the buns.
- Sauté Vegetables:
- Heat olive oil in a skillet over medium-high heat. Add onions and mushrooms; sauté for 7–8 minutes until softened and golden. Remove and set aside.
- Cook Patties:
- In the same skillet or on a grill, cook burger patties for 3–4 minutes per side (medium doneness).
- Assemble Burgers:
- Top each patty with sautéed mushrooms and onions, then a slice of Swiss cheese. Cover with a lid for 1–2 minutes to melt cheese.
- Toast and Dress Buns:
- Toast burger buns if desired. Spread mayonnaise or Dijon mustard on the bottom half of each bun. Add arugula or lettuce, then the patty. Finish with the remaining bun.
- Serve:
- Serve hot with waffle fries on the side.
