• 1 egg
• 2 cloves garlic, minced
• 1 tsp salt
• ½ tsp black pepper
• ½ tsp thyme

How to Make French Onion Meatballs

   In a large bowl, mix ground beef, breadcrumbs, egg, garlic, salt, pepper, thyme, and cheese until well combined. Roll into 1-inch balls.
2. Brown the Meatballs:
   Heat a drizzle of oil in a skillet over medium heat. Sear the meatballs until golden on all sides (they’ll finish cooking in the sauce). Remove and set aside.
3. Caramelize the Onions:
   In the same pan, melt butter and add sliced onions. Cook slowly for 15–20 minutes until soft and golden brown. Add a pinch of sugar to help them caramelize.
4. Make the Sauce:
   Sprinkle flour over the onions and stir for 1–2 minutes. Slowly pour in beef broth while stirring. Add Worcestershire sauce and thyme. Simmer until the sauce thickens.
5. Combine:
   Return the meatballs to the pan. Cover and simmer for 10–12 minutes, letting the flavors blend and the meatballs cook through.

How to Serve

Serve these French Onion Meatballs over creamy mashed potatoes, buttered noodles, or crusty toasted bread to soak up the sauce. Sprinkle extra cheese on top and broil for a few minutes for that authentic French onion soup flavor.

This recipe makes an excellent meatball dinner for family nights or special occasions. Add a light salad or roasted vegetables for a complete beef dish that everyone will love.

Tips for a Perfect French Onion Meatballs Recipe

• Use 80/20 ground beef for juicy, tender meatballs.
• Don’t rush caramelizing the onions—slow cooking brings out the sweetness.

• Store leftovers in the fridge for up to 3 days or freeze for later.
• Reheat gently to preserve the sauce’s texture.
