# 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 cremini or button mushrooms, sliced
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 (if baking)
15 - Salt, to taste
# Step-by-Step:
01 - Preheat the oven to 425°F.
02 - Arrange waffle fries on a baking sheet in a single layer, drizzle with olive oil, and bake for 22 to 28 minutes, turning halfway through until golden and crisp. Season with salt.
03 - In a bowl, combine ground beef, salt, black pepper, and Worcestershire sauce. Gently mix and form into four equal patties slightly larger than the buns.
04 - Heat 1 tablespoon of olive oil in a skillet over medium-high heat. Add onions and mushrooms and sauté for 7 to 8 minutes until softened and golden. Remove from skillet and set aside.
05 - In the same skillet or on a grill, cook the burger patties for 3 to 4 minutes per side until medium doneness.
06 - Top each patty with the sautéed mushrooms and onions, then place a slice of Swiss cheese on each. Cover with a lid for 1 to 2 minutes until the cheese melts.
07 - Toast burger buns if desired. Spread mayonnaise and/or Dijon mustard on the bottom half of each bun. Add a handful of arugula or lettuce, followed by the patty with toppings. Finish with the top bun.
08 - Serve the burgers hot alongside the crispy waffle fries.
