# What You'll Need:
→ Mushroom Swiss Burgers
01 - 1 lb ground beef (80/20 blend)
02 - 1 tsp salt
03 - ½ tsp black pepper
04 - 1 tbsp Worcestershire sauce
05 - 1 tbsp olive oil
06 - 8 oz sliced cremini or button mushrooms
07 - 1 small onion, thinly sliced
08 - 4 slices Swiss cheese
09 - 4 burger buns
10 - 2 tbsp mayonnaise (optional)
11 - 2 tbsp Dijon mustard (optional)
12 - 1 cup baby arugula or lettuce leaves
→ Waffle Fries
13 - 1½ lbs frozen waffle fries
14 - 1 tbsp olive oil (for baking)
15 - Salt, to taste
# Method:
01 - Preheat the oven to 425°F.
02 - Arrange waffle fries in a single layer on a baking sheet, drizzle with olive oil, and bake for 22 to 28 minutes, turning halfway, until golden and crisp. Season with salt.
03 - Combine ground beef, salt, pepper, and Worcestershire sauce in a bowl. Gently mix and form into 4 equal patties, slightly larger than the buns.
04 - Heat 1 tablespoon olive oil in a skillet over medium-high heat. Add sliced onions and mushrooms; sauté for 7 to 8 minutes until softened and golden. Remove and set aside.
05 - In the same skillet or on a grill, cook burger patties for 3 to 4 minutes per side for medium doneness.
06 - Top each patty with the sautéed mushrooms and onions, then a slice of Swiss cheese. Cover with a lid and cook for 1 to 2 minutes to melt the cheese.
07 - Toast burger buns if desired. Spread mayonnaise and/or Dijon mustard on the bottom halves. Add arugula or lettuce, then the patties. Top with the remaining buns.
08 - Serve burgers hot with the crispy waffle fries on the side.
