Instructions

Mix Meatballs: In a large bowl, combine ground beef, egg, 1/4 cup flour, 1 teaspoon salt, and 1/2 teaspoon pepper. Gently mix until just combined, then form into 1.5-inch meatballs. Don’t overmix to keep them tender for your Crockpot French Onion Meatballs.
Sauté Onions: Heat olive oil in a large skillet over medium heat. Add thinly sliced onions and a pinch of salt. Sauté, stirring occasionally, until deeply caramelized and fragrant, building incredible flavor for this French Onion Meatballs recipe.
Deglaze Pan: Add minced garlic and thyme to the caramelized onions; cook for 1 minute. Pour in red wine to deglaze the pan, scraping up any browned bits. Stir in beef broth, Worcestershire sauce, and onion powder, bringing to a gentle simmer.
Cook Meatballs: Carefully transfer the onion-broth mixture to your crockpot. Gently add the prepared meatballs to the liquid. Cover and cook on low for 3-4 hours or on high for 2-3 hours, until the meatballs are cooked through and tender, creating delicious Crockpot French Onion Meatballs.
Thicken Sauce: In a small bowl, whisk 2 tablespoons of flour with 1/4 cup of the hot broth until smooth. Stir this slurry into the crockpot. Cook for another 15-20 minutes until the sauce slightly thickens. Then, stir in the shredded Gruyere cheese.
Serve Meatballs: Once the cheese has melted beautifully into the rich sauce, your Crockpot French Onion Meatballs are ready! Ladle generously into bowls, garnish with fresh chopped parsley, and enjoy this ultimate comforting meal. Pure bliss!

Notes

Deeply caramelize onions for signature savory depth; this crucial step builds incredible foundational flavor.

Store leftover meatballs and sauce in an airtight container in the refrigerator for 3-4 days.

Substitute Gruyere with Swiss or provolone cheese for a similar melty texture, though the flavor will differ slightly.

Serve these comforting meatballs warm, ideally over creamy mashed potatoes or with crusty bread.

For enhanced flavor, brown your meatballs in a skillet before adding them to the slow cooker with the sauce.
