What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavors and comforting textures without any fuss. Here’s what you’ll need:

For the Meatballs:

• 1 lb (450g) ground beef (80/20 blend works best)
• 1/2 cup (60g) breadcrumbs
• 1/4 cup (60ml) milk
• 1 large egg
• 1/4 cup (30g) grated Parmesan cheese (adds richness)
• 2 garlic cloves, minced
• 1 tsp dried thyme
• 1 tsp onion powder
• 1/2 tsp salt
• 1/4 tsp black pepper

For the Onion Sauce:

• 2 large yellow onions, thinly sliced
• 3 tbsp (45ml) unsalted butter
• 1 tbsp (15ml) olive oil
• 1 tbsp (8g) all-purpose flour
• 2 cups (480ml) beef broth (use low-sodium for better control over salt)
• 1 tsp Worcestershire sauce
• 1/2 tsp sugar (to enhance caramelization)
• 1/4 tsp dried thyme
• Salt and pepper, to taste

Optional Garnishes:

• Fresh parsley, chopped

If you’re missing an ingredient, don’t worry—there are plenty of substitutions and variations coming up later in this post!

Equipment Needed

• Large skillet or sauté pan
• Mixing bowl for the meatball mixture
• Wooden spoon or spatula
• Sharp knife and cutting board (for slicing onions)
• Measuring cups and spoons
• Optional: Cast iron skillet (for even cooking and added flavor)

If you don’t have a cast iron skillet, a regular non-stick or stainless steel skillet works just fine. I personally love using cast iron for the even heat distribution and extra depth of flavor it adds to the onions. Just make sure to season your pan well to prevent sticking!

Preparation Method

1. Prepare the meatball mixture: In a large mixing bowl, combine the ground beef, breadcrumbs, milk, egg, Parmesan cheese, minced garlic, dried thyme, onion powder, salt, and pepper. Mix gently until everything is well combined, but don’t overwork the meat—this keeps the meatballs tender.
2. Form the meatballs: Roll the mixture into golf-ball-sized meatballs, about 1.5 inches (4cm) in diameter. You should get about 12-15 meatballs.
3. Brown the meatballs: Heat a large skillet over medium heat and add 1 tablespoon of olive oil. Once hot, add the meatballs and cook for 2-3 minutes per side, until browned. Don’t overcrowd the pan—work in batches if needed. Remove the browned meatballs and set them aside on a plate.
4. Caramelize the onions: In the same skillet, lower the heat to medium-low and add the butter and remaining olive oil. Add the sliced onions and sprinkle with the sugar and a pinch of salt. Cook for about 10-15 minutes, stirring occasionally, until the onions are golden brown and caramelized.
5. Make the sauce: Sprinkle the flour over the caramelized onions and stir to coat evenly. Cook for 1-2 minutes to eliminate the raw taste of the flour. Slowly pour in the beef broth, stirring constantly to avoid lumps. Add the Worcestershire sauce and dried thyme, and bring the sauce to a simmer.
6. Add the meatballs: Return the browned meatballs to the sauce and simmer gently for 10-12 minutes, or until the meatballs are cooked through and the sauce has thickened.
7. Final touches: Taste and adjust the seasoning with additional salt and pepper if needed. If desired, sprinkle grated Gruyère or Swiss cheese over the meatballs and let it melt into the sauce.

Serve hot over mashed potatoes, pasta, or with a side of crusty bread to soak up the delicious sauce!

Cooking Tips & Techniques

Here are some tried-and-true tips to make sure your French onion meatballs come out perfect every time:

• Don’t rush the onions: The key to a truly flavorful onion sauce is taking your time to caramelize the onions. Cook them low and slow until they’re golden and jammy. If they’re cooking too fast, lower the heat and stir frequently to prevent burning.
• Don’t overwork the meatball mixture: Overmixing can make your meatballs tough. Use your hands or a fork to gently combine the ingredients until just mixed.
• Use fresh thyme: If you have fresh thyme on hand, it adds an even deeper, fragrant flavor to the sauce. Just toss in a few sprigs and remove them before serving.
• Double the sauce: If you love extra sauce, feel free to double the onion sauce ingredients. It’s perfect for drizzling over mashed potatoes or soaking up with bread.
• Don’t overcrowd the pan: Give your meatballs space to brown evenly. Overcrowding traps steam and prevents that golden crust.

Variations & Adaptations

Want to mix things up? Here are a few ways to adapt this recipe:

• Gluten-Free: Swap breadcrumbs for gluten-free panko or almond flour, and use gluten-free flour in the sauce.
• Dairy-Free: Replace milk with almond milk or oat milk, and leave out the Parmesan cheese.
• Vegetarian Version: Use plant-based ground meat or create vegetarian meatballs using lentils or chickpeas.
• Cheesy Twist: Stir shredded Gruyère or mozzarella into the sauce for an extra creamy finish.
• Seasonal Variations: Add sautéed mushrooms or spinach for a seasonal touch.

I once tried swapping the ground beef for ground turkey, and it turned out surprisingly delicious! It’s lighter but still packed with flavor.

Serving & Storage Suggestions

Here are some tips for serving and storing your French onion meatballs:

• Serving Suggestions: Serve the meatballs over creamy mashed potatoes, buttered egg noodles, or with a side of crusty bread to soak up the sauce. Pair with a crisp green salad for a balanced meal.
• Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
• Freezing: Freeze the meatballs and sauce separately in freezer-safe containers for up to 3 months. Thaw in the fridge overnight before reheating.
• Reheating: Warm the meatballs and sauce on the stovetop over medium heat, stirring occasionally, until heated through. Add a splash of broth or water if the sauce thickens too much.
• Flavor Development: The flavors in the sauce deepen over time, so this dish tastes even better the next day!
