How to Make French Onion Meatballs: Step-by-Step

1. Make the Meatballs

In a large bowl, mix together ground beef, breadcrumbs, egg, Parmesan, garlic powder, onion powder, salt, pepper, and parsley until just combined. Form into 1 1/2-inch meatballs (about 12–14 total).

2. Brown the Meatballs

Heat a tablespoon of oil in a skillet over medium heat. Add meatballs in batches and sear until browned on all sides, about 6–8 minutes total. Transfer to a plate (they don’t need to be cooked through yet).

3. Caramelize the Onions

In the same skillet, melt butter. Add sliced onions and sprinkle with salt and sugar. Cook over medium-low heat for 15–20 minutes, stirring occasionally, until onions are deeply golden and soft.

4. Build the Sauce

Add minced garlic to the caramelized onions and cook for 1 minute. Stir in flour and cook for 1 minute more. Slowly pour in the beef broth, Worcestershire sauce, and thyme. Stir until smooth and simmer for 3–4 minutes until slightly thickened.

5. Simmer Meatballs in the Sauce

Return the meatballs to the skillet, nestling them into the sauce. Cover and simmer for 10–12 minutes, or until the meatballs are fully cooked through and sauce is rich.

6. Top with Cheese and Broil

Sprinkle shredded Gruyère or mozzarella over the meatballs. Transfer the skillet to the oven under the broiler for 2–3 minutes, or until the cheese is melted and bubbly. Watch closely to avoid burning.

7. Serve

Garnish with parsley and serve hot. Ideal with mashed potatoes, egg noodles, rice, or toasted baguette slices.

Tips and Variations

• Add Mushrooms: Sauté mushrooms with the onions for added depth.
  

How to Store and Reheat

Refrigerator:
Store in an airtight container for up to 4 days. Reheat gently in a skillet or microwave until warmed through.

Freezer:
Freeze meatballs and sauce in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before reheating.

Reheat:
Reheat in a covered skillet over medium-low heat. Add a splash of broth if needed to loosen the sauce.
