1. In a large bowl, combine ground beef, ground pork, breadcrumbs, Parmesan cheese, chopped parsley, egg, minced garlic, salt, black pepper, onion powder, and thyme. Mix well until all ingredients are fully incorporated and the mixture holds together.
2. Shape the mixture into meatballs, roughly 1 to 1.5 inches in diameter, and arrange them in a single layer in the bottom of the crock pot for even cooking.
3. In a separate bowl, combine the thinly sliced onion, beef broth, Worcestershire sauce, and soy sauce, stirring until the flavors meld into a savory sauce.
4. Pour the broth and onion mixture over the meatballs in the crock pot, making sure each meatball is mostly covered by the liquid.
5. Cover the crock pot with the lid and cook on low for 6–8 hours or cook on high for 3–4 hours, until the meatballs are tender and cooked through.
6. About 15–30 minutes before serving, layer slices of provolone or Swiss cheese on top of the meatballs and cover again, allowing the cheese to melt into gooey perfection.
7. Once the cheese is bubbly and melty, serve the meatballs hot, garnished with fresh parsley if desired.

Frequently Asked Questions
Got questions? I’ve gathered the answers to the most common queries so your French onion meatballs turn out perfect every time.
- Can I brown the meatballs before adding them to the crock pot?
Yes. Browning the meatballs in a skillet over medium-high heat for 2–3 minutes per side before placing them in the crock pot will seal in juices and add a deeper flavor, but it’s optional—cooking them directly in the crock pot still yields tender, flavorful meatballs.
- How can I achieve deeper caramelization of the onions?
For richer, sweeter onions, sauté the thinly sliced onion in a bit of olive oil over medium heat for 10–15 minutes until golden brown before mixing them with the beef broth, Worcestershire sauce, and soy sauce. Then pour the mixture over the meatballs as directed.
- What’s the best way to store and reheat leftovers?
Store cooled leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, place meatballs and sauce in a saucepan over low heat until warmed through or return them to the crock pot on low for 1–2 hours. They can also be microwaved in a covered dish, stirring halfway through.
- Can I freeze these meatballs for later use?
Absolutely. Shape the meatballs and freeze them in a single layer on a baking sheet for 1–2 hours. Transfer to a freezer bag for up to 3 months. When ready to cook, add frozen meatballs directly to the crock pot with the broth and onion mixture, increasing cook time by about 1 hour on low or 20–30 minutes on high.
- How do I thicken the sauce if it’s too thin?
About 30 minutes before serving, whisk together 1 tablespoon of cornstarch with 2 tablespoons of cold water to form a slurry. Stir it into the crock pot, switch to high heat, and cook uncovered until the sauce thickens to your liking.
- What are some good serving suggestions?
These meatballs are delicious over cooked pasta or rice, spooned into toasted sub rolls for French onion meatball sandwiches, or served alongside crusty bread to soak up the sauce. A green salad pairs nicely to balance the richness.
- Can I customize the cheese or meat in this recipe?
Yes. Swap provolone or Swiss for mozzarella, cheddar, or pepper jack for different flavors. You can also use ground turkey or chicken instead of beef and pork, though the texture will be slightly leaner—consider adding an extra tablespoon of olive oil or using full-fat cheese to maintain richness.
