Ingredients

The Beef Filling

1.5 lbs Ground beef lean (85/15)
3 large Sweet onions thinly sliced
2 cloves Garlic minced
2 tbsp Butter
1 tbsp Olive oil
1/2 cup Beef broth low sodium
2 tbsp Worcestershire sauce
1 tsp Soy sauce
1 tsp Dried thyme
to taste Salt
to taste Black pepper
1 tbsp All-purpose flour
8 Brioche buns or sturdy hamburger buns
1.5 cups Swiss cheese shredded (or Gruyère or Provolone)

Optional Garnish

Fresh parsley chopped, for garnish

Equipment

Large deep skillet or Dutch oven
Wooden spoon
Baking sheet
Broiler

Method

Caramelize the Onions

In a large deep skillet or Dutch oven over medium heat, melt the butter and heat the olive oil. Add the thinly sliced onions and cook, stirring occasionally, for 15 minutes until soft and translucent. Continue cooking for another 10-15 minutes until deeply golden brown and caramelized, scraping up any browned bits.
Stir in the minced garlic and dried thyme, cooking for 1 minute until fragrant.
Push onions to one side. Increase heat to medium-high, add ground beef, and cook 5-7 minutes until browned. Drain excess fat.
Sprinkle flour over mixture and cook 1 minute. Stir in beef broth, Worcestershire sauce, soy sauce; season with salt and pepper. Simmer 5-10 minutes until thickened.
Preheat broiler. Toast bun halves lightly under broiler for 1 minute. Spoon filling onto bottoms, top with Swiss cheese.
Broil 1-2 minutes until cheese bubbles. Top with bun halves and serve immediately.

Notes

For faster caramelization, add a teaspoon of sugar after Step 1. Cheese variations: Gruyère or Provolone for nutty flavor. Storage: Cool filling, store in fridge up to 4 days or freeze up to 3 months. Reheat on stovetop with broth if needed. Serve with classic French slaw or fries.
