Step-by-Step Instructions
1: Make the Meatballs
-
In a large mixing bowl, combine ground beef, breadcrumbs, egg, garlic, parsley, onion powder, Parmesan, salt, and pepper.
-
Mix gently with your hands until just combined (avoid over-mixing to keep meatballs tender).
-
Form into 1-inch meatballs and place them on a parchment-lined baking sheet.
-
Bake at 400°F (200°C) for 15 minutes, or until browned. (Alternatively, sear them in a skillet for extra flavor.)
2: Caramelize the Onions
-
Heat butter and olive oil in a large skillet over medium heat.
-
Add sliced onions and cook slowly, stirring often, for 25–30 minutes.
-
Add sugar and thyme, continue cooking until onions are golden brown.
-
Stir in garlic and cook for another minute.
3: Make the Sauce
-
Sprinkle flour over the caramelized onions and stir until combined (this helps thicken the sauce).
-
Slowly pour in the wine, scraping up browned bits.
-
Add beef broth gradually, whisking to avoid lumps.
-
Simmer for 10–15 minutes until thickened. Season with salt and pepper.
4: Combine and Finish
-
Add baked/seared meatballs into the onion sauce.
-
Simmer for another 10 minutes to allow flavors to meld.
-
Sprinkle Gruyère cheese on top, then broil until bubbly and golden (optional but highly recommended).
-
Garnish with fresh parsley and serve hot.
Tips for the Best French Onion Meatballs with Savory Onion Sauce
-
Caramelize patiently: Don’t rush the onions—they need slow cooking to develop their deep, sweet flavor.
-
Cheese choice matters: Gruyère is traditional, but mozzarella or provolone also melt beautifully.
-
Add wine if possible: White wine elevates the flavor, but if you don’t use alcohol, just add extra broth.
-
Make ahead: Prepare meatballs and sauce separately a day in advance, then reheat together.
Serving Suggestions

Classic Pairing: Over creamy mashed potatoes for the ultimate comfort meal.

Low-Carb Option: Serve with roasted cauliflower or zucchini noodles.
