Ingredients

• 2 pounds ground beef
• 2 tablespoons Worcestershire sauce
• 1/2 teaspoon garlic powder
• 1/2 cup butter, divided
• 1 extra-large sweet onion, thinly sliced
• 12 slices thick-cut sandwich bread (Texas toast)
• 6 slices American cheese
• 6 slices Swiss cheese
• 2 tablespoons yellow mustard
• Salt and pepper

Directions

1. Melt 4 tablespoons butter in a skillet over medium heat; add onions, season with salt and pepper, and cook 15–20 minutes until caramelized.
2. Mix ground beef with Worcestershire, garlic powder, 1 teaspoon salt, and 1/2 teaspoon pepper; divide into 6 flat oval patties.
3. Spread 1 teaspoon mustard on 6 slices of bread.
4. Cook patties on a preheated griddle or skillet, 3 minutes per side.
5. After flipping, top each patty with caramelized onions, 1 slice American cheese, and 1 slice Swiss; cook until cheese is melty and patties reach at least 6 minutes total.
6. Transfer patties onto the mustard-coated bread slices.
7. Wipe the griddle, then melt 2 tablespoons butter and place sandwiches on to toast.
8. Grill 2–3 minutes per side, adding remaining butter when flipping, until golden and crisp.
9. Cut in half and serve hot.

Tips

• Flatten patties well—they shrink as they cook and should match the bread’s shape.
• Lower heat if the bread browns too quickly so the cheese has time to melt fully.

FAQ

Can I use regular sandwich bread?
Yes, but Texas toast provides the best sturdiness and crunch.

Can I caramelize onions ahead of time?
Absolutely—store them in the fridge up to 3 days to speed up prep.

Can I use different cheeses?
Provolone or pepper jack both melt beautifully and add great flavor.

How do I reheat leftovers?
Warm in a skillet over low heat to re-crisp the bread without drying the patty.
