Ingredients

1½ lbs ground beef (80/20 recommended)
2 large yellow onions, thinly sliced
2 tbsp butter
1 tbsp olive oil
2 cloves garlic, minced
1 cup shredded Gruyère, Swiss, or mozzarella cheese
¾ cup breadcrumbs
2 large eggs
½ cup beef broth
1 tbsp Worcestershire sauce
1 tsp salt
½ tsp black pepper
1 tsp dried thyme
½ tsp onion powder
½ tsp garlic powder
Fresh parsley or thyme for garnish (optional)

Instructions

Caramelize the onions
In a large skillet over medium-low heat, add butter and olive oil. Add sliced onions and cook slowly for 25–30 minutes, stirring occasionally, until deeply golden and caramelized. Add garlic during the last minute. Remove from heat and cool slightly.
Prepare the meat mixture
In a large mixing bowl, combine ground beef, breadcrumbs, eggs, beef broth, Worcestershire sauce, salt, pepper, thyme, onion powder, and garlic powder. Mix gently until just combined.
Add onions
Fold in most of the caramelized onions, reserving a small amount for topping.
Stuff with cheese
Press half of the meat mixture into a loaf shape on a lined baking sheet. Create a shallow trench down the center and fill with shredded cheese. Top with remaining meat mixture, sealing edges well.
Top and bake
Sprinkle reserved onions over the top. Bake at 375°F (190°C) for 50–60 minutes, or until internal temperature reaches 160°F (71°C).
Rest and serve
Let the meatloaf rest for 10 minutes before slicing. Garnish with fresh herbs and serve warm.

Tips for the Best French Onion Meatloaf

Low and slow onions are key—don’t rush caramelization.
Use Gruyère or Swiss for authentic French onion flavor.
Avoid overmixing to keep the meatloaf tender.
Let it rest before slicing to keep the cheese inside.
