Step‑by‑Step Instructions for French Onion Meatballs with Caramelized Onions and Cheese
Step 1: Soak the Breadcrumbs
Begin by soaking 1 ½ cups of fresh breadcrumbs or panko in ¼ cup plus 2 tablespoons of whole milk for about 5 minutes. This crucial step ensures your meatballs stay moist and tender. The breadcrumbs will absorb the milk while you prepare the other ingredients, making them perfectly fluffy.
Step 2: Prepare the Meatball Mixture
In a large mixing bowl, combine the soaked breadcrumbs with 1 ½ pounds of ground beef, 1 tablespoon of chopped parsley, 1 teaspoon of fresh thyme leaves, 1 teaspoon of herbes de Provence, and about 1 teaspoon each of salt and black pepper. Add ½ of a finely minced large white onion, 4 pressed garlic cloves, ¾ cup of grated Gruyere cheese, and 1 whisked egg. Gently mix until just combined, then shape the mixture into 2-tablespoon meatballs and chill in the refrigerator for 15 minutes.
Step 3: Sear the Meatballs
Heat 2 tablespoons of olive oil in a large oven-safe skillet over medium-high heat. Once hot, sear the chilled meatballs in batches for about 8 to 10 minutes, turning occasionally until they are evenly browned on all sides. Once cooked, carefully remove the meatballs from the skillet and set them aside to keep warm while you make the sauce.
Step 4: Caramelize the Onions
In the same skillet, add the remaining 2 tablespoons of olive oil and 2 tablespoons of ghee or butter. Toss in 2 ½ sliced white onions, season with salt and pepper to taste, and cook over medium heat for 20-25 minutes. Stir occasionally until the onions are deeply caramelized, taking on a rich golden-brown color and sweet flavor.
Step 5: Build the Flavor
Stir in 4 pressed garlic cloves, 1 teaspoon of herbes de Provence, and 1 teaspoon of dried thyme to the caramelized onions, stirring for about 30 seconds until fragrant. Then, pour in ¼ cup of sherry or white wine, allowing it to bubble for 30 seconds while scraping up any browned bits from the skillet to enhance the sauce's flavor.
Step 6: Make the Sauce
Sprinkle in 1 ½ tablespoons of flour and stir for an additional 30 seconds, allowing the raw flour taste to cook off. Gradually whisk in 2 ¼ cups of beef stock, stirring until the sauce is smooth. Let it simmer for about 5 minutes until slightly thickened, then add 2 teaspoons of fresh thyme leaves for a touch of brightness.
Step 7: Combine Meatballs with Sauce
Carefully nestle the seared meatballs back into the lovely sauce in your skillet, ensuring they are well coated. Top each meatball with the remaining ¾ cup of Gruyere cheese and 1 cup of shredded mozzarella for that perfect cheesy melt.
Step 8: Broil to Perfection
Transfer your skillet to a preheated broiler for 5-7 minutes, watching closely until the cheese is melted, bubbly, and slightly golden. The combination of melty cheese and savory meatballs creates an irresistible dish that's sure to impress.
Step 9: Garnish and Serve
Once broiled to perfection, remove the skillet from the oven and garnish your French Onion Meatballs with extra fresh thyme. Serve immediately with warm rustic bread or over creamy mashed potatoes for a comforting meal that’s both hearty and heartwarming.

How to Store and Freeze French Onion Meatballs

Reheating: To reheat, thaw overnight in the fridge, then warm in the oven at 350°F (175°C) until heated through. Optionally, broil for a few minutes to re-melt the cheese on top.
Avoiding Texture Loss: If reheating from frozen, add a splash of beef stock when warming to keep the meatballs juicy and the sauce creamy.

Expert Tips for French Onion Meatballs
-
Choose Quality Meat: Use a good quality ground beef with some fat content for juicy, flavorful meatballs. Lean meat can lead to dryness.
-
Proper Chilling: After shaping the meatballs, chill them for at least 15 minutes. This helps them hold their shape during cooking.
-
Perfect Caramelization: When cooking the onions, patience is key! Cook them low and slow for 20-25 minutes for deep caramelization and rich flavor in your French Onion Meatballs with Caramelized Onions and Cheese.
-
Avoid Overmixing: When combining the ingredients, mix just until incorporated. Overmixing can lead to tough meatballs, ruining their tenderness.
-
Watch the Broiling: Keep a close eye while broiling; the cheese can go from perfectly bubbly to burnt in mere seconds!
-
Experiment with Cheese: If Gruyere isn't available, feel free to substitute with other melting cheeses like Emmental or aged cheddar for a different twist in flavor.
French Onion Meatballs with Caramelized Onions and Cheese Recipe FAQs
How do I choose the best onions for this recipe?
When selecting onions for your French Onion Meatballs, aim for large, firm white onions with a smooth, dry skin. They should feel heavy for their size and have no dark spots or softness. This ensures they will caramelize beautifully and add the sweetest flavor to your sauce.
What’s the best way to store leftover meatballs?
Absolutely! You can store any leftovers in an airtight container in the refrigerator for up to 3 days. To keep them moist, I recommend pouring a little extra sauce over the meatballs before sealing the container. This will help maintain their tenderness and flavor.
Can I freeze the French Onion Meatballs?
Yes, you can! To freeze your meatballs, first arrange them in a single layer on a parchment-lined baking sheet and freeze until solid. Once frozen, transfer them to a freezer-safe container or zip-top bag where they can keep for up to 3 months. When you’re ready to enjoy them, thaw in the refrigerator overnight, then reheat in a 350°F oven for about 20-25 minutes until heated through.
What if my meatballs fall apart while cooking?
If your meatballs are falling apart, it might be due to too much moisture or not enough binder. Ensure you soak the breadcrumbs just enough to become moist (about 5 minutes) and use the correct amount of egg to bind everything together. If you find that they’re still crumbling, consider adding a tablespoon or two more breadcrumbs for added structure.
Are there any dietary considerations to note?
Definitely! If you or someone you’re cooking for has dietary restrictions, this recipe can be adjusted. For a gluten-free version, use gluten-free breadcrumbs and ensure your beef stock is also gluten-free. If you're concerned about cheese, feel free to substitute dairy-free cheese options or omit them altogether for a lighter dish.
How do I know when my onions are properly caramelized?
Caramelizing onions perfectly requires patience! Cook them over medium heat, stirring occasionally. You’re aiming for a rich, deep golden-brown color and a sweet aroma. This process usually takes about 20-25 minutes, but keep an eye on them, as cooking too quickly can lead to bitter-tasting onions. Enjoy the delightful transformations!
