Prepare the Onions and Aromatics
Next, it's time to transform those onions into a delectable caramelized base. Slice your onions thinly (about 7 cups once sliced). While you’re at it, chop your garlic and pick the leaves off the thyme until you have around 2 tablespoons. This fragrant combination is where the magic begins!
Mix the Meatball Ingredients
In a large bowl, combine your minced garlic, thyme, a quarter cup of Gruyère, panko breadcrumbs, milk, egg, Worcestershire sauce, salt, and black pepper. Mix these together first before adding in the ground beef. Here’s a tip: use your hands to combine the mixture gently, creating a cohesive blend without overworking the meat.
Form and Bake the Meatballs
Shape your mixture into 32 to 34 meatballs, each about 1 ½ inches in size. Arrange them on a lined baking sheet, keeping a little space in between each meatball. Pop them in the oven at 400°F for about 15 to 20 minutes, until they’re beautifully browned and cooked through.
Cook the Onion Sauce
While your meatballs are baking, melt butter in a skillet and add your sliced onions, thyme, salt, and pepper. Cook this concoction, stirring frequently, for about 25 to 30 minutes until your onions are soft and spectacularly caramelized. Don’t rush this step; it’s where depth of flavor comes from.
Combine Meatballs and Sauce
Once your meatballs are out of the oven, add them directly to the loveliness of the onion sauce. Stir gently to coat them, and spread them out in a layer for even distribution.
Broil for That Cheesy Finish
The final step is purely indulgent! Sprinkle the remainder of your Gruyère cheese over the meatballs and place the skillet under the broiler for about 3 to 4 minutes, or until the cheese is bubbling and beginning to brown.
And there you have it—sumptuous, cheesy French onion meatballs that will tantalize your taste buds and impress your friends! Serve them with some crusty bread on the side, and enjoy!

Variations on Cheesy French Onion Meatballs
Cheesy French Onion Turkey Meatballs
Looking for a lighter take? Try cheesy French onion turkey meatballs! Ground turkey provides a leaner option while still absorbing all those delightful flavors. Just swap the ground beef for 1.5 pounds of ground turkey, and follow the same easy preparation steps. For added moisture, consider incorporating a bit of grated zucchini or shredded carrot. This not only keeps the meatballs juicy but also boosts their nutrition. Plus, turkey pairs beautifully with the savoriness of French onion flavors—you won’t be disappointed!

Instructions
Cooking Instructions
- Arrange one oven rack 6 to 8 inches from the broiler and a second rack in the middle of the oven. Heat the oven to 400°F. Line a rimmed baking sheet with parchment paper or a silicone baking mat.
- Halve and thinly slice 2 pounds yellow onions (about 7 cups). Pick the leaves from 1 small bunch fresh thyme until you have 2 tablespoons. Mince 2 garlic cloves. Grate 6 ounces Gruyère cheese on the large holes of a box grater (about 1 ½ cups).
- Place the garlic, 2 teaspoons of the thyme, ¼ cup of the Gruyère cheese, ½ cup unseasoned dried breadcrumbs or panko, ½ cup whole or 2% milk, 1 large egg, 2 teaspoons Worcestershire sauce, 1 ¼ teaspoons of the kosher salt, and ¼ teaspoon black pepper in a large bowl and stir to combine. Add 1 ½ pounds ground beef and use your fingers to combine the meat and flavorings. Handle the meat gently and do not overmix.
- Form the mixture into 32 to 34 (about 1 ½-inch) meatballs (about 2 tablespoons each). Place on the baking sheet, spacing them about ¾-inch apart.
- Bake on the middle rack until browned and cooked through or until an instant-read thermometer inserted into the center of a meatball registers at least 165°F, 15 to 20 minutes. Meanwhile, make the sauce.
- Melt 2 tablespoons unsalted butter in a 12-inch cast iron or other broiler-safe, heavy-bottomed skillet over medium heat. Add the onions, 1 tablespoon of the thyme, remaining 1 ¼ teaspoons kosher salt, and remaining ½ teaspoon black pepper. Cook, stirring frequently with a wooden spoon and reducing the heat if the onions start to burn, until the onions have reduced by over half, are very soft, and deep golden-brown, 25 to 30 minutes.
- Sprinkle 2 tablespoons all-purpose flour over the onions and stir until the flour is completely incorporated and leaves a film on the bottom of the skillet and begins to brown, about 1 minute. Add ¼ cup dry white wine and scrape up any browned bits on the bottom of the skillet. Continue to stir until the wine is evaporated, about 30 seconds.
- Add 1 (14.5-ounce) can beef broth and whisk to combine. Increase the heat back to medium if it was lowered while cooking the onions. Bring to a boil and cook until the sauce thickens enough to coat the back of a spoon, 6 to 8 minutes. Remove the pan from the heat. Add 1 teaspoon balsamic or sherry vinegar and stir to combine. Taste and season with more kosher salt and black pepper as needed.
- Remove the meatballs from the oven. Set the oven to broil. Using tongs or a slotted spoon, transfer the meatballs to the sauce. Gently stir to coat the meatballs in the sauce, then spread into an even layer. Sprinkle with the remaining 1 ¼ cups Gruyère cheese.
- Transfer the skillet to the upper rack and broil until the cheese is melted, bubbly, and browned in spots, 3 to 4 minutes. Garnish with the remaining 1 teaspoon thyme leaves and serve with crusty bread, if desired.
