Ingredients for French Onion Meatballs

For the Onions

• 2 tablespoons olive oil
• 4 medium yellow onions, thinly sliced (about 6 cups)
• 3 cloves garlic, thinly sliced
• 2 bay leaves
• 1 1/2 teaspoons kosher salt
• 1 teaspoon fresh thyme leaves
• 1/2 teaspoon freshly ground black pepper
• 1/3 cup dry white wine (such as Sauvignon Blanc)
• 2 tablespoons unsalted butter

For the Meatballs

• 1 pound 90% lean ground beef
• 1 large egg, beaten
• 1/3 cup panko breadcrumbs
• 1 teaspoon kosher salt
• 1/2 teaspoon freshly ground black pepper
• 2 tablespoons olive oil

For the Sauce and Serving

• 1 tablespoon all-purpose flour
• 2 cups low-sodium chicken broth
• 1 teaspoon Dijon mustard
• 1 teaspoon Worcestershire sauce
• 6 ounces freshly grated Gruyere cheese (about 1 cup)
• Toasted baguette slices, for serving

Step-by-Step Instructions

1. Caramelize the Onions

Start by heating olive oil in a large skillet over medium heat. Add the sliced onions and garlic, stirring to coat them in the oil. Toss in the bay leaves, salt, thyme, and black pepper. Cook the onions slowly, stirring occasionally, for 25–30 minutes until they’re golden brown and caramelized.

Once the onions are caramelized, increase the heat to medium-high. Add the white wine to deglaze the pan, scraping up any browned bits. Let the wine simmer for 1–2 minutes until mostly evaporated. Stir in the butter and remove the pan from heat.

2. Prepare the Meatballs

In a large bowl, combine ground beef, beaten egg, panko breadcrumbs, salt, and black pepper. Mix gently until the ingredients are just combined—overmixing can make the meatballs tough. Shape the mixture into 12 evenly sized meatballs.

3. Cook the Meatballs

Heat olive oil in a large skillet over medium heat. Add the meatballs in batches, cooking for 2–3 minutes per side until browned. They don’t need to cook through completely at this stage. Remove the browned meatballs and set them aside.

4. Create the Sauce

Using the same skillet, sprinkle the flour over the remaining oil and whisk for 1–2 minutes to create a roux. Gradually add the chicken broth, whisking constantly to avoid lumps. Stir in Dijon mustard and Worcestershire sauce. Let the sauce simmer for 3–4 minutes until it thickens slightly.

5. Combine Meatballs and Onions

Add the caramelized onions back to the skillet, followed by the browned meatballs. Spoon some sauce over the meatballs to coat them. Cover the skillet and simmer on low heat for 10–12 minutes until the meatballs are fully cooked.

6. Top with Gruyere Cheese

Sprinkle the grated Gruyere cheese evenly over the meatballs and onions. Cover the skillet again and cook for 2–3 minutes, or until the cheese melts into a gooey layer.

7. Serve with Toasted Baguette Slices

Transfer the French Onion Meatballs to a serving dish or serve directly from the skillet. Pair with toasted baguette slices for dipping into the rich, cheesy sauce.

Tips for Success

• Caramelizing onions takes time: Be patient during this step. The slow cooking process unlocks their natural sweetness.
• Use quality Gruyere cheese: It’s worth it for that nutty, melty goodness that makes this dish special.
• Make ahead: You can prepare the onions and meatballs a day in advance. Store them separately and combine when ready to cook.

FAQs About French Onion Meatballs

1. Can I use a different type of cheese?

Yes! While Gruyere is traditional, you can substitute Swiss cheese or even mozzarella for a similar melty texture.

2. Can I make this dish vegetarian?

You can use plant-based ground meat for the meatballs and vegetable broth for the sauce to create a vegetarian-friendly version.

3. What wine works best for deglazing?

A dry white wine like Sauvignon Blanc or Pinot Grigio adds acidity and depth to the onions. If you don’t have wine, you can use chicken broth as a substitute.

4. Can I freeze leftovers?

Absolutely. Freeze the meatballs and sauce in an airtight container for up to 3 months. Thaw overnight in the fridge and reheat in a skillet.

5. Can I use store-bought meatballs?

Yes, pre-made meatballs save time. Just ensure they’re fully cooked before adding them to the sauce.

6. What’s the best bread to serve with this dish?

Toasted baguette slices are classic, but sourdough or even garlic bread works wonderfully.
