Step-by-Step Instructions for French Onion Meatballs

1. Prepare the meatballs – In a large bowl, combine breadcrumbs and milk. Let sit for 5 minutes to soften. Add ground beef, egg, onion, garlic, Worcestershire sauce, parsley, salt, and pepper. Mix gently until combined, being careful not to overwork the meat. Shape into golf ball-sized meatballs.
2. Brown the meatballs – Heat olive oil in a skillet. Sear the meatballs in batches until browned on all sides (they don’t need to cook through yet). Transfer to a plate.
3. Caramelize the onions – In the same skillet, melt butter. Add onions, sugar, and salt. Cook slowly over medium-low heat, stirring occasionally, until golden and caramelized (about 25–30 minutes). Add garlic and cook another minute.
4. Make the gravy – Stir in flour and cook for 2 minutes. Slowly whisk in beef broth and juice until smooth. Add thyme, salt, and pepper. Simmer until thickened.
5. Assemble the dish – Transfer meatballs to a baking dish. Pour onion gravy over them. Sprinkle with shredded cheese.
6. Bake – Place in a 375°F (190°C) oven for 20–25 minutes, until meatballs are fully cooked and cheese is bubbling.
7. Serve – Garnish with parsley and serve hot.

Tips for Juicy French Onion Meatballs

• Don’t overmix – Gently combine ingredients to keep meatballs tender.
• Use milk-soaked breadcrumbs – This creates a moist texture.
• Rest after browning – Let meatballs rest briefly before baking so juices redistribute.

Perfect Pairings for a Beef Dinner

These beef dishes pair beautifully with classic sides:

• Creamy mashed potatoes
• Buttered egg noodles
• Garlic bread or crusty baguette

• Fresh salad for balance
