Instructions

Let’s dive into the simple steps to make these savory Crock Pot French Onion Meatballs!

1. Prepare the Meatballs

Start by mixing together the ground beef, breadcrumbs, egg, French onion soup mix, garlic powder, salt, and pepper in a large bowl. Add a splash of milk to make the mixture moist and easy to form into meatballs. Shape the mixture into meatballs, about 1 to 1.5 inches in diameter. You should get around 20-25 meatballs, depending on the size.

2. Brown the Meatballs (Optional)

While you can skip this step and simply add the raw meatballs directly to the crock pot, browning them first adds a rich layer of flavor and helps seal in the juices. Heat a bit of oil in a large skillet over medium-high heat. Brown the meatballs on all sides, about 2-3 minutes per side. Transfer the meatballs to a plate once browned.

3. Prepare the Onion Gravy

In the same skillet, sauté the onions over medium heat until they turn golden brown and caramelized, about 10 minutes. This caramelization process adds depth and sweetness to the onion flavor. Once caramelized, add the beef broth to the skillet, scraping up any browned bits from the bottom of the pan. This will create a rich, flavorful gravy.

4. Combine Everything in the Crock Pot

Place the browned meatballs in the bottom of the slow cooker. Pour the caramelized onion mixture and beef broth over the meatballs, making sure they’re well-coated in the liquid. This will help keep the meatballs moist and infuse them with the delicious French onion flavor as they cook.

5. Cook on Low

Cover the crock pot and cook on low for 6-7 hours or on high for 3-4 hours, until the meatballs are cooked through and tender.

6. Add the Cheese

Once the meatballs are fully cooked, sprinkle shredded Swiss or Gruyere cheese over the top of the meatballs. Cover the crock pot and cook for an additional 10-15 minutes, until the cheese has melted and is bubbly.

7. Serve and Enjoy

Once the cheese has melted and everything is bubbly and delicious, serve your Crock Pot French Onion Meatballs with mashed potatoes, over rice, or in a hoagie bun for a delicious meatball sandwich. Be sure to spoon plenty of that rich onion gravy over the top. Enjoy!

How to Serve Crock Pot French Onion Meatballs

Here are a few ideas to serve these delicious meatballs:

  • With Mashed Potatoes: The rich gravy and tender meatballs go perfectly with mashed potatoes. Spoon the gravy over the potatoes for a comforting meal.
  • In a Meatball Sub: Serve the meatballs on a toasted hoagie bun with melted cheese on top for a French onion meatball sandwich.
  • With Rice: Spoon the meatballs and gravy over a bed of fluffy white or brown rice for a complete, hearty meal.
  • As an Appetizer: Serve the meatballs as a party appetizer. Use toothpicks for easy serving and let guests dip into the gravy.

Additional Tips

  • For a Lighter Version: You can swap out the ground beef for ground turkey or chicken to make the meatballs leaner.
  • Make Ahead: You can prepare the meatballs in advance and store them in the fridge or freezer. When you’re ready to cook, simply add them to the crock pot with the onion gravy.
  • Leftovers: Leftover meatballs and gravy can be stored in an airtight container in the fridge for up to 3 days. Reheat in the microwave or stovetop for the best results.
  • Add More Veggies: If you want to bulk up the dish with more vegetables, try adding carrots or mushrooms to the slow cooker with the onions.

FAQs

  1. Can I use frozen meatballs?
    Yes! If you’re in a hurry, you can use frozen meatballs. Just add them directly to the crock pot and let them cook in the gravy.
  2. What kind of cheese can I use besides Swiss?
    Gruyere cheese is another classic option that melts beautifully. You can also use provolone or mozzarella for a different flavor.
  3. Can I make this recipe without browning the meatballs?
    Yes, you can skip the browning step. However, browning the meatballs adds extra flavor and helps to seal in the juices.
  4. Can I use a different type of soup mix?
    If you don’t have French onion soup mix, you can use onion soup mix or even onion powder combined with a little beef bouillon for flavor.
  5. How do I prevent the meatballs from falling apart?
    Be sure to mix the meatball ingredients gently and don’t overwork the meat. Adding breadcrumbs and eggs helps bind the meatballs together.
  6. Can I make this recipe in the oven instead?
    Yes! You can bake the meatballs in the oven at 375°F for 20-25 minutes and then simmer them in the onion gravy on the stovetop for about 10 minutes to meld the flavors.
  7. How long do leftovers last?
    Leftovers can be stored in the refrigerator for up to 3 days. Reheat thoroughly before serving.
  8. Can I freeze the meatballs?
    Yes! You can freeze the meatballs before or after cooking. If freezing before, bake or fry them, then place them in a freezer-safe container. When ready to serve, cook them in the slow cooker as directed.
  9. Can I use vegetable broth instead of beef broth?
    Yes, you can use vegetable broth if you want a vegetarian-friendly option. Keep in mind the flavor will be a little different but still delicious.
  10. Can I add other seasonings to the meatballs?
    Absolutely! Feel free to experiment with your favorite seasonings, such as thyme, rosemary, or garlic powder, to customize the flavor.

Ingredients

Scale
  • 1 lb ground beef (or ground turkey for a lighter option)
  • 1/2 cup breadcrumbs (preferably Italian breadcrumbs)
  • 1/4 cup grated Parmesan cheese
  • 1 egg
  • 1 teaspoon garlic powder
  • 1 teaspoon dried thyme
  • Salt and pepper to taste
  • 2 tablespoons olive oil (for searing)

For the French Onion Sauce:

  • 2 cups French onion soup (store-bought or homemade)
  • 1/2 cup beef broth
  • 1/2 cup heavy cream (optional for a creamier sauce)
  • 1 tablespoon Worcestershire sauce
  • 1/2 teaspoon dried thyme
  • 1 tablespoon soy sauce (optional, for added depth of flavor)

For Garnish (optional):

  • Chopped fresh parsley
  • Shredded mozzarella or Gruyère cheese (optional for topping)

Instructions

  1. Prepare the Meatballs:
    In a large bowl, combine the ground beef, breadcrumbs, grated Parmesan, egg, garlic powder, dried thyme, salt, and pepper. Mix until everything is well combined. Shape the mixture into meatballs, about 1 to 1 1/2 inches in diameter.
  2. Sear the Meatballs (optional):
    Heat the olive oil in a large skillet over medium-high heat. Add the meatballs in batches and sear them on all sides until they are browned (about 3-4 minutes per side). This step adds flavor, but if you’re short on time, you can skip it and just add the raw meatballs directly to the Crock Pot.
  3. Prepare the French Onion Sauce:
    In a separate bowl, mix together the French onion soup, beef broth, heavy cream (if using), Worcestershire sauce, soy sauce (if using), and dried thyme. Stir well to combine.
  4. Slow Cook the Meatballs:
    Place the browned (or raw) meatballs into the Crock Pot. Pour the French onion sauce over the meatballs, making sure they are evenly coated.
  5. Cook:
    Cover the Crock Pot and cook on low for 6 hours or high for 3 hours, until the meatballs are cooked through and tender. The sauce will thicken as it cooks.
  6. Optional Cheese Topping:
    About 15 minutes before serving, sprinkle shredded mozzarella or Gruyère cheese on top of the meatballs and let it melt into the sauce.
  7. Serve:
    Garnish with chopped fresh parsley and serve the French onion meatballs with mashed potatoes, rice, or a baguette to soak up the flavorful sauce.

Notes

  • You can use ground turkey or chicken if you prefer a lighter meatball option.
  • If you prefer a thicker sauce, you can whisk in a slurry of cornstarch and water during the last hour of cooking.
  • For added depth of flavor, consider using caramelized onions in the French onion sauce.
