Step-by-step Preparation of Cheesy French Onion Meatballs
Preheat your oven
To kick off this delicious adventure, preheat your oven to 400°F (200°C). Ensure one oven rack is set about 6 to 8 inches below the broiler, while another sits in the middle. This will help create the perfect atmosphere for baking your meatballs. While you wait, line a rimmed baking sheet with parchment paper or a silicone baking mat to prevent sticking—this will make cleanup much easier!
Prepare the onions and aromatics
Next up, let’s tackle the aromatic base that will elevate your Cheesy French Onion Meatballs to the next level. Start by halving and thinly slicing 2 pounds of yellow onions—that’s about 7 cups! The key to flavor here is patience, so make sure to take your time. Also, pick the leaves from a small bunch of fresh thyme until you gather about 2 tablespoons. Finally, mince 2 cloves of garlic for that aromatic depth.
Mix the meatball ingredients
In a large bowl, combine garlic, thyme, Gruyère cheese, panko breadcrumbs, milk, egg, Worcestershire sauce, and seasonings. Mix thoroughly before adding in 1.5 pounds of ground beef. Gently combine the ingredients with your fingers—this will help you create perfect meatballs without making them tough.
Form and bake the meatballs
Now, it’s time to shape your meatballs! Scoop out about 2 tablespoons of the mixture and roll them into balls, approximately 32 to 34 in total. Place them on your prepared baking sheet, ensuring they are spaced about ¾-inch apart. Pop them in the oven and bake for 15 to 20 minutes, or until they reach an internal temperature of 165°F (74°C).
Caramelize the onions
While your meatballs are baking, let’s move on to caramelizing the onions. In a large skillet, melt 2 tablespoons of unsalted butter and add in your prepared onions, thyme, salt, and pepper. Cook them over medium heat while stirring frequently for 25 to 30 minutes until they're deep golden-brown and incredibly fragrant.
Create the sauce
Once the onions are perfectly caramelized, sprinkle 2 tablespoons of all-purpose flour over them. Stir it in, letting it cook for about a minute before adding beef broth. Whisk until well combined and simmer for about 6 to 8 minutes until the sauce thickens enough to coat a spoon. Finish it off with a teaspoon of balsamic or sherry vinegar, adjusting seasoning to taste.
Combine meatballs and sauce
When your meatballs are ready, carefully place them in the skillet with the sauce. Gently stir to coat and ensure an even layer. This melding of flavors is where the magic happens—so enjoy the wafting aroma!
Broil until cheesy perfection
Finally, turn your oven to broil! Sprinkle the remaining Gruyère cheese on top of the meatballs and sauce. Broil for 3 to 4 minutes until the cheese is melted, bubbly, and golden. Serve your Cheesy French Onion Meatballs with crusty bread for an unforgettable meal!
