Ingredients for Cheesy French Onion Meatballs

Let’s start by gathering everything you need. This recipe is made with simple ingredients you probably already have in your pantry and fridge:

For the Meatballs:

1 lb (450g) ground beef
1/2 cup breadcrumbs
1/4 cup grated Parmesan cheese
1 egg
2 cloves garlic, minced
1 tsp onion powder
1 tsp Italian seasoning
Salt and pepper to taste

For the Sauce and Garnish:

2 tbsp olive oil
2 large onions, thinly sliced
2 tbsp butter
1 tsp sugar
2 cups beef broth
1/2 cup dry white wine (optional)
1 tbsp Worcestershire sauce
1 tbsp all-purpose flour
1 cup shredded Gruyère or Swiss cheese
Fresh parsley for garnish (optional)

Preparing the Meatballs

The first step in creating this masterpiece is making the meatballs. Here’s how:

Mix the Meatball Ingredients:
In a large mixing bowl, combine the ground beef, breadcrumbs, Parmesan cheese, egg, garlic, onion powder, Italian seasoning, salt, and pepper. Use your hands or a sturdy spatula to mix everything until evenly combined. Pro tip: Don’t overmix; keeping the mixture light will ensure tender meatballs.
Shape the Meatballs:
Roll the mixture into 1-inch meatballs. The size is just right for cooking evenly and absorbing all the flavors of the sauce later on. Arrange them on a plate or a lined baking sheet while you heat the skillet.
Brown the Meatballs:
Heat 2 tablespoons of olive oil in a large skillet over medium heat. Once the oil is shimmering, add the meatballs in a single layer. Cook them for 6–8 minutes, turning occasionally, until they’re browned on all sides. They don’t need to be fully cooked at this stage—they’ll finish cooking in the sauce. Remove the browned meatballs from the skillet and set them aside.

The Magic of French Onion Sauce

Now that the meatballs are ready, it’s time to create the sauce that gives this dish its signature flavor. Think rich, caramelized onions swimming in a savory broth—it’s the stuff dreams are made of! Stay tuned for Part 2, where I’ll guide you through making the sauce and bringing everything together for the ultimate cheesy finish.

Creating the Sauce and Bringing It All Together

Welcome back! Now that we’ve prepped and browned our meatballs, it’s time to focus on the heart of this dish: the French onion sauce. This sauce is the soul of the recipe, packed with caramelized onions, a touch of sweetness, and a savory depth that ties everything together. Trust me, the aroma alone will have everyone gathering in the kitchen, asking, “What’s cooking?”

Making the French Onion Sauce

This step requires a little patience, but the payoff is a sauce so rich and flavorful, it’s worth every second.

Caramelize the Onions:
Using the same skillet you cooked the meatballs in (because less cleanup is always a win!), add 2 tablespoons of butter and let it melt over medium-low heat. Once melted, toss in the thinly sliced onions and sprinkle them with 1 teaspoon of sugar.
Stir the onions occasionally, letting them cook low and slow. The sugar helps the onions caramelize faster while enhancing their natural sweetness. After about 15–20 minutes, the onions should be golden brown, soft, and oh-so-fragrant.
Add the Flour:
Sprinkle 1 tablespoon of all-purpose flour over the caramelized onions. Stir well to coat the onions evenly. This step helps thicken the sauce, giving it that luscious consistency.
Deglaze and Build the Sauce:
Pour in 2 cups of beef broth, followed by 1/2 cup of dry white wine (if you’re using it). Add 1 tablespoon of Worcestershire sauce for that umami kick. As the liquid heats, use a wooden spoon to scrape up all the browned bits stuck to the bottom of the skillet—those bits are flavor gold!
Simmer:
Bring the sauce to a gentle simmer and let it cook for 5–7 minutes, stirring occasionally. The sauce will thicken slightly and develop even deeper flavors. This is where the magic happens—those caramelized onions meld with the broth and seasonings to create the ultimate comfort sauce.

Reuniting the Meatballs and Sauce

Now that your sauce is ready, it’s time to reunite it with the meatballs.

Add the Meatballs:
Carefully place the browned meatballs back into the skillet, nestling them into the sauce. Spoon some of the sauce over the meatballs to coat them evenly.
Simmer Together:
Cover the skillet with a lid and let everything simmer for 10–15 minutes. During this time, the meatballs will finish cooking, absorbing all the delicious flavors of the sauce. Stir gently halfway through to ensure the meatballs are evenly coated.

The Cheesy Finish

This wouldn’t be a recipe for Cheesy French Onion Meatballs without the star ingredient: melted cheese!

Add the Cheese:
Preheat your oven’s broiler. While it heats, sprinkle 1 cup of shredded Gruyère (or Swiss cheese if you prefer) evenly over the meatballs and sauce. Gruyère is my favorite because it melts beautifully and has a nutty flavor that pairs perfectly with the caramelized onions.
Broil to Perfection:
Transfer the skillet to the oven and broil for 2–3 minutes, or until the cheese is melted, bubbly, and golden brown. Keep a close eye on it—you don’t want to overdo it!
Garnish (Optional):
For a fresh pop of color and a hint of herbaceousness, sprinkle the finished dish with chopped parsley before serving. This step is optional, but it adds a nice touch.

Serving Suggestions

These Cheesy French Onion Meatballs are a versatile dish that pairs beautifully with a variety of sides. Here are a few ideas to make this meal even more unforgettable:

Crusty Bread: Perfect for soaking up every drop of that delicious sauce.
Mashed Potatoes: The creamy potatoes provide a lovely contrast to the savory meatballs.
Pasta or Rice: Serve the meatballs and sauce over your favorite carb for a heartier meal.
Steamed Veggies: Add a side of broccoli or green beans for a balanced plate.

Now that your skillet is brimming with cheesy, saucy goodness, it’s time to gather everyone around the table and dig in. The combination of flavors and textures in this dish is guaranteed to make it a hit!

Q: How do I store leftovers?
A: Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm gently on the stovetop or in the microwave. Add a splash of beef broth to loosen the sauce if needed.

Q: Can I freeze this dish?
A: Definitely! Let the meatballs and sauce cool completely, then transfer them to a freezer-safe container. Freeze for up to 3 months. Thaw in the fridge overnight and reheat as desired.
