# Ingredients:

→ Main Ingredients

01 - 2 pounds ground beef
02 - 2 tablespoons Worcestershire sauce
03 - ½ teaspoon garlic powder
04 - Salt, to taste
05 - ½ teaspoon cracked black pepper

→ Caramelized Onions

06 - ½ cup butter, divided
07 - 1 extra-large sweet onion, peeled and sliced into thin strips
08 - Salt, to taste
09 - Black pepper, to taste

→ Sandwich Components

10 - 12 slices thick-cut sandwich bread (Texas toast)
11 - 6 slices American cheese
12 - 6 slices Swiss cheese
13 - 2 tablespoons yellow mustard

# Instructions:

01 - Set a large sauté pan or skillet over medium heat. Add 4 tablespoons of butter to the skillet. Once melted, stir in the onion slices. Sprinkle with salt and pepper. Turn heat to medium-low and cook, stirring often, for 15–20 minutes until soft and caramelized. Turn off the heat.
02 - In a large bowl, mix ground beef with Worcestershire sauce, garlic powder, salt, and black pepper. Divide into six equal portions and shape into thin, large oval patties slightly larger than the bread slices.
03 - Lay out 12 slices of bread. Spread a generous teaspoon of yellow mustard on six of the slices.
04 - Preheat a griddle or skillet to medium heat. Cook the beef patties for 3 minutes per side. After flipping the patties, top each with caramelized onions, one slice of American cheese, and one slice of Swiss cheese. Cook for a total of 6 minutes.
05 - Place each cooked patty on a mustard-slathered slice of bread. Top with another slice of bread.
06 - Clean the griddle with a paper towel and melt 2 tablespoons of butter on the surface. Toast the sandwiches for 2–3 minutes per side or until golden brown. Add the remaining butter when flipping the sandwiches.
07 - Remove from the griddle, slice in half, and serve immediately.
