How to Make French Onion Meatballs with Rich Sauce

Step 1: Caramelize the Onions

Begin by slicing yellow onions thinly and cooking them slowly in butter over low heat until they turn golden brown and sweet. This process takes patience but is crucial for achieving the rich flavor that defines the dish.

Step 2: Prepare the Meatball Mixture

In a large bowl, combine the ground beef, caramelized onions (reserve some for the sauce), breadcrumbs, egg, minced garlic, fresh thyme, Worcestershire sauce, salt, and pepper. Mix gently until just combined to avoid dense meatballs.

Step 3: Form and Brown the Meatballs

Shape the mixture into evenly sized meatballs, about 1 to 1.5 inches in diameter. Heat a skillet with butter and brown them on all sides, creating a delicious crust while keeping the center juicy.

Step 4: Make the Rich Sauce

Remove the meatballs and add reserved caramelized onions back to the pan. Stir in flour to absorb the butter and create a roux, gradually whisk in beef broth, and simmer until the sauce thickens into a shiny, flavorful coating perfect for the meatballs.

Step 5: Combine and Simmer

Return the browned meatballs to the sauce, cover, and simmer gently for 15-20 minutes, allowing them to absorb the sauce’s richness and finish cooking evenly.

Pro Tips for Making French Onion Meatballs with Rich Sauce

• Low and Slow for Onions: Caramelize your onions on low heat to develop maximum sweetness without burning.
• Gentle Mixing: Handle the meat mixture carefully to keep meatballs tender, avoiding overmixing.
• Consistent Size: Make uniformly sized meatballs so they cook evenly and look polished.
• Deglaze the Pan: Don’t skip whisking broth into the browned bits; they add incredible depth to the sauce.
• Rest Before Serving: Let meatballs sit a few minutes after cooking to let juices redistribute for optimal juiciness.
