How To Make French Onion Meatballs Recipe

Step 1: Prepare the Meatball Mixture

In a large mixing bowl, combine the ground beef, finely chopped onion, minced garlic, breadcrumbs, grated Parmesan cheese, egg, salt, black pepper, Worcestershire sauce, and dried thyme. Use your hands or a spoon to mix everything until just combined. Be careful not to overmix, as this can make the meatballs tough.

Step 2: Form the Meatballs

Shape the mixture into 1 to 1 1/2-inch meatballs, placing them on a plate or baking sheet. This recipe should yield about 18-20 meatballs depending on size.

Step 3: Brown the Meatballs

Heat a large skillet over medium heat and add a splash of oil. Once hot, add the meatballs in batches, being careful not to overcrowd the pan. Brown the meatballs on all sides, about 3-4 minutes per side. They do not need to be fully cooked at this stage since they will finish cooking in the broth. Remove the browned meatballs and set aside.

Step 4: Simmer in Beef Broth

In the same skillet, pour in the beef broth and scrape up any browned bits from the bottom of the pan—this adds incredible flavor. Return the meatballs to the skillet and reduce the heat to low. Cover and let the meatballs simmer gently for about 15-20 minutes until cooked through and tender.

Step 5: Add the Gruyère Cheese

Preheat your oven’s broiler. Transfer the meatballs and broth to a baking dish (if your skillet is oven-safe, you can use that). Sprinkle the shredded Gruyère cheese evenly over the meatballs. Place under the broiler for 2-3 minutes or until the cheese is melted, bubbly, and slightly golden.

Step 6: Serve

Serve your French Onion Meatballs hot, spooning some of the flavorful broth over the top. They pair wonderfully with crusty bread, mashed potatoes, or a simple green salad.

Expert Tips

• For the best texture, use ground beef that is about 80% lean. This balance keeps the meatballs juicy without being greasy.
• Caramelize the onions separately if you want an even deeper onion flavor. You can sauté the onions slowly in butter until golden brown and then mix them into the meatball mixture.
• Don’t skip the Worcestershire sauce—it adds a wonderful umami depth that mimics the flavor of traditional French onion soup.
• If you prefer smaller meatballs, adjust the cooking time accordingly to ensure they’re fully cooked but not dry.
• Use freshly grated Gruyère cheese for the best melting and flavor. Pre-shredded cheese often contains additives that affect melting quality.
• For an extra touch of elegance, garnish with a sprinkle of fresh thyme or parsley before serving.

Variations and Customizations

• Turkey or Chicken Meatballs: Substitute ground beef with ground turkey or chicken for a leaner option. Adjust cooking times as necessary.
• Vegetarian Version: Use a plant-based ground meat substitute or lentils mixed with breadcrumbs and seasonings.
• Cheese Options: Swap Gruyère with Swiss cheese or mozzarella for a different but still melty topping.
• Additional Herbs: Add fresh rosemary or sage to the meatball mixture for more complex flavors.
• Spice It Up: Include a pinch of red pepper flakes in the meat mixture or broth for a little heat.

How to Store Leftovers

Store any leftover French Onion Meatballs in an airtight container in the refrigerator for up to 3 days. To reheat, place them in a covered skillet over low heat or warm them in the oven until heated through, adding a splash of beef broth to keep them moist. These meatballs also freeze well. Freeze in a single layer on a baking sheet, then transfer to a freezer-safe bag or container. Thaw overnight in the refrigerator before reheating.

FAQ

What can I serve with French Onion Meatballs?

These meatballs go great with mashed potatoes, buttered noodles, steamed vegetables, or even a fresh green salad. They also pair nicely with crusty bread to soak up the flavorful broth.
