20 min2 servings

French onion meatballs are a soul-warming pan of ground beef in caramelized onion sauce with all the flavor—and melty cheese topping—of French onion soup, making for a hearty, crowd-pleasing dinner.

Ingredients
2 tablespoons butter, divided
1 large onion, thinly sliced
1-1/2 teaspoons salt, divided
1 teaspoon pepper, divided
1 teaspoon minced fresh rosemary
3 tablespoons dry red wine
2 tablespoons all-purpose flour
2 cups beef stock
1 pound ground beef
1/3 cup panko bread crumbs
1 large egg, beaten
2 tablespoons minced fresh parsley
2 garlic cloves, minced
2 teaspoons Italian seasoning
1 cup shredded Gruyere cheese
French bread baguette slices, toasted, optional
Instructions
1 Caramelize the onions
2 Preheat the oven to 400°F. Fit a 15x10x1-inch baking sheet with a wire rack and coat both with cooking spray. Set aside. In a large oven-safe skillet, melt 1 tablespoon butter over medium-low heat. Add the onions and stir to coat. Cook until onions begin to caramelize and are very soft, stirring occasionally, about 15 to 20 minutes. Stir in 1/2 teaspoon salt, 1/2 teaspoon pepper and rosemary. Add the wine; cook until it has evaporated, 2 to 3 minutes, stirring constantly.
3 Make the sauce
4 Stir in the remaining butter; once melted, whisk in the flour until lightly browned. Slowly whisk in beef stock; bring to a simmer and cook until thickened, 2 to 3 minutes. Remove from heat; set aside.
5 Mix, form and bake the meatballs
6 In a large bowl, combine ground beef, bread crumbs, egg, parsley, garlic, Italian seasoning, remaining 1 teaspoon salt and remaining 1/2 teaspoon pepper. Form the mixture into 24 meatballs and place them on the prepared pan. Bake them until their internal temperature reaches 165°, 15 to 20 minutes.
7 Broil with cheese
8 Transfer meatballs to the skillet with the onion sauce; stir them in gently to combine. Top the meatballs with an even layer of shredded Gruyere. Preheat the broiler. Broil skillet 3 to 4 inches from heat until cheese is melted, 2 to 3 minutes. If desired, serve with toasted baguette slices.
