Instructions

Step 1: Prepare the Meatballs

1. Prep the Ingredients: Gather and prepare all meatball ingredients for easy access.
2. Soak the Breadcrumbs: Place breadcrumbs in a dish, add milk, and let soak for 5 minutes. Meanwhile, put the ground beef in a large mixing bowl.
3. Combine Ingredients: Add the soaked breadcrumbs, parsley, thyme, herbes de Provence, salt, pepper, minced onion, garlic, ¼ cup of Gruyere cheese, and whisked egg to the beef. Gently mix with your hands until combined, being careful not to overmix.
4. Shape the Meatballs: Scoop 2-tablespoon portions of the meat mixture, roll into balls with slightly damp hands, and place them on a tray. Chill the meatballs in the fridge for 15 minutes.

Step 2: Make the French Onion Sauce 5. Prepare Ingredients: While meatballs chill, prep all ingredients for the French onion sauce. 6. Brown the Meatballs: Heat 2 tablespoons of olive oil in a large cast-iron skillet over medium-high heat. Sear meatballs in batches, browning them on all sides for about 8-10 minutes. Remove and set aside. 7. Caramelize the Onions: In the same skillet, add the remaining 2 tablespoons of olive oil and the ghee. Once melted, add sliced onions with a pinch of salt and pepper, cooking them down for 20-25 minutes until deeply caramelized. 8. Add Garlic and Seasonings: Stir in the garlic, herbes de Provence, and dried thyme, cooking briefly until fragrant. 9. Deglaze the Pan: Add sherry or wine, allowing it to reduce for 30 seconds. 10. Make the Sauce: Sprinkle in flour, stir, then pour in the beef stock, whisking until smooth. Let the sauce simmer for about 5 minutes.

Step 3: Combine and Broil 11. Prepare for Broiling: Preheat your broiler to high. 12. Finish the Meatballs: Turn off the heat under the sauce and stir in fresh thyme. Nestle the meatballs back into the pan, sprinkle with remaining Gruyere and mozzarella cheese, and broil for 5-7 minutes until the cheese melts.

Step 4: Serve 13. Garnish and Serve: Garnish with extra thyme leaves and serve with toasted bread or over mashed potatoes for a complete, comforting meal.

Serving and Storage Tips

French Onion Meatballs are best enjoyed fresh and hot, with the melted cheese gooey and the sauce rich and savory. Here are some serving ideas and tips for storing leftovers:

Serving Suggestions

• With Bread: Serve these meatballs with crusty, toasted bread. The bread helps to soak up the rich French onion sauce, making each bite deliciously satisfying.
• Over Mashed Potatoes: These meatballs pair perfectly with creamy mashed potatoes, adding a comforting touch to the dish.
• With Pasta or Rice: For a heartier meal, serve over pasta or rice, allowing the sauce to coat every bite.
• As a Sandwich: For a fun twist, use the meatballs and sauce in a toasted baguette or hoagie roll, topped with a bit of extra cheese for a meatball sandwich.

Storage Tips

• Refrigerating Leftovers: Allow the meatballs and sauce to cool completely, then transfer them to an airtight container. Store in the refrigerator for up to 3-4 days.
• Freezing: For longer storage, place cooled meatballs and sauce in a freezer-safe container. Freeze for up to 2 months. When ready to enjoy, thaw in the refrigerator overnight.
• Reheating: To reheat, place meatballs and sauce in a skillet over medium heat until warmed through. Alternatively, reheat in the microwave in 1-minute intervals, stirring in between. For a fresh melted cheese topping, sprinkle a bit of extra mozzarella or Gruyere before reheating.

With these serving and storage tips, you’ll be able to savor these French Onion Meatballs long after your first meal.

Variations

French Onion Meatballs are already bursting with flavor, but with a few adjustments, you can customize this recipe to suit different tastes and dietary needs. Here are some fun and delicious variations to try:

1. Chicken or Turkey Meatballs

For a lighter option, substitute the ground beef with ground chicken or turkey. This variation still pairs beautifully with the French onion sauce but offers a leaner, slightly different flavor profile.

2. Vegetarian French Onion “Meatballs”

Swap the ground meat for a plant-based alternative or make your own with ingredients like lentils, mushrooms, and breadcrumbs. You can also use store-bought vegetarian meatballs, cooking them according to the package directions and then adding them to the French onion sauce.

3. Extra Cheesy Meatballs

If you’re a cheese lover, add more Gruyere and mozzarella on top. You could even mix in some Swiss cheese for extra richness. For an even cheesier experience, try stuffing each meatball with a small cube of cheese before rolling it, so there’s a gooey center in every bite.

4. Wine-Braised Meatballs

Instead of using only beef stock, make the sauce with half beef stock and half red wine. The wine adds a deeper flavor to the sauce and pairs well with the caramelized onions.

5. Spicy French Onion Meatballs

For those who enjoy a bit of heat, add a pinch of red pepper flakes or finely chopped fresh chili peppers to the meatball mixture. Alternatively, add some spice to the sauce itself for a gentle kick.

6. Gluten-Free French Onion Meatballs

To make this recipe gluten-free, use gluten-free breadcrumbs and substitute the flour in the sauce with a gluten-free flour blend or cornstarch. Make sure all other ingredients, like beef stock, are gluten-free as well.

7. Low-Carb French Onion Meatballs

For a low-carb version, use crushed pork rinds or almond flour in place of breadcrumbs. You can also skip the flour in the sauce and let it thicken naturally by reducing it longer on the stove.

8. Italian-Style French Onion Meatballs

Add an Italian twist by mixing a bit of basil, oregano, and Parmesan cheese into the meatball mixture. You could also substitute the herbes de Provence with Italian seasoning for a more Mediterranean flavor profile.

9. French Onion Meatball Casserole

Transform this dish into a casserole by adding cooked pasta (such as penne or rigatoni) to the pan with the meatballs and sauce before adding the cheese. Bake until bubbly for a delicious, one-pan meal.

10. Mushroom French Onion Meatballs

For an earthy twist, add sliced mushrooms to the sauce while it’s simmering. Mushrooms pair beautifully with the caramelized onions and enhance the umami flavors in the dish.

Experimenting with these variations can bring fresh twists to your French Onion Meatballs, keeping the dish exciting and customizable for every occasion!

FAQs

Here are some common questions and helpful answers to make your French Onion Meatballs perfectly every time:

1. Can I make French Onion Meatballs ahead of time?

Yes, you can prepare the meatballs a day in advance. Shape and refrigerate them in an airtight container. You can also make the sauce ahead and store it separately. When ready to serve, simply heat the sauce, cook the meatballs, and combine.

2. Can I use store-bought meatballs for this recipe?

Absolutely! If you’re short on time, use frozen or pre-cooked meatballs. Just cook them according to the package instructions and add them to the sauce before broiling with cheese on top.

3. How can I make the meatballs more tender?

Avoid overmixing the meat mixture, as it can make the meatballs tough. Soaking the breadcrumbs in milk helps keep the meatballs tender and juicy. Letting the meatballs chill before cooking also helps them hold together better.

4. What’s the best way to caramelize onions for this recipe?

Cook the onions low and slow for about 20-25 minutes, stirring often. This will bring out their natural sweetness and give them a rich, jammy texture. Adding a pinch of salt helps draw out moisture, speeding up the caramelization.

5. Can I use another type of cheese besides Gruyere?

Yes, Gruyere is traditional, but you can also use Swiss, fontina, or even provolone for a similar flavor. Mozzarella is a good addition for extra meltiness, but it doesn’t have the same nutty flavor as Gruyere or Swiss.

6. What should I serve with French Onion Meatballs?

French Onion Meatballs go well with mashed potatoes, rice, crusty bread, or even pasta. The sauce is rich, so serving it with a starch will help balance the dish and soak up the delicious sauce.

7. Can I freeze French Onion Meatballs?

Yes! Once cooled, place the meatballs and sauce in a freezer-safe container. They can be stored for up to 2 months. Thaw in the refrigerator overnight before reheating on the stovetop or in the microwave.

8. Can I substitute dried herbs for fresh herbs?

Yes, you can use dried thyme and parsley if fresh herbs aren’t available. Use about half the amount, as dried herbs are more concentrated in flavor. Adjust the seasoning to taste.

9. How can I make the sauce thicker?

To thicken the sauce, simmer it for a few extra minutes to reduce the liquid. Alternatively, add an additional teaspoon of flour or a cornstarch slurry (1 teaspoon cornstarch mixed with 1 tablespoon water) to the sauce while simmering.

10. How do I prevent meatballs from falling apart during cooking?

Ensure the meatball mixture is well-combined but not over-mixed, which can make them tough. Chilling the formed meatballs for at least 15 minutes before cooking helps them hold their shape. Wetting your hands while shaping also helps create smooth, firm meatballs.
