Description
Tender meatballs slow-cooked in a rich French onion sauce with caramelized onions and beefy depth, finished with melty cheese if desired.
Ingredients
MEATBALLS: ground beef (or beef/pork mix)
Panko breadcrumbs
Milk
1 egg, lightly beaten
Minced garlic
Dried thyme
Salt and pepper
FRENCH ONION SAUCE: 2 large sweet onions, thinly sliced
Butter
Rich beef broth
Dry red wine (optional)
Worcestershire sauce
Dried thyme
1 bay leaf
Salt and pepper
FOR SERVING (optional): crusty bread or baguette
Shredded Gruyere or Swiss cheese
Fresh parsley, chopped
Instructions
1. In a bowl gently mix ground meat with panko, milk, egg, garlic, dried thyme, salt, and pepper; form 1-inch meatballs (about 25–30), taking care not to overmix.
2. (Optional) Brown meatballs in a hot skillet to add flavor and help them hold shape.
3. In the same skillet melt butter; cook sliced onions 10–15 minutes until soft and golden; deglaze with red wine if using and simmer briefly.
4. Transfer onions to the slow cooker; place meatballs on top; add beef broth, Worcestershire, dried thyme, and bay leaf; gently combine.
5. Cover and cook on LOW 6–8 hours or HIGH 3–4 hours until meatballs are cooked through and tender; discard bay leaf.
6. Serve meatballs with their onion gravy over mashed potatoes, bread, rice, or noodles; top with shredded Gruyere or Swiss and parsley if desired.
Notes
For true French onion soup vibes: ladle into oven-safe bowls, top with bread and cheese, and broil until bubbly.
Add sliced mushrooms with the onions for earthy depth.
Spice option: a pinch of red pepper flakes or smoked paprika.
Herb upgrade: add fresh rosemary and thyme sprigs (remove before serving).
Thicken the sauce with a cornstarch slurry during the last 30 minutes.
Frozen meatballs work; cook until they reach 160°F (71°C).
Stores 3–4 days refrigerated; freezes up to 3 months.
