What Are Crockpot French Onion Meatballs?
Crockpot French Onion Meatballs are a savory, slow-cooked dish where flavorful beef or pork meatballs are simmered in a rich and aromatic French onion soup base. The French onion soup is traditionally made with caramelized onions, beef broth, and herbs, which add an irresistible depth of flavor to the meatballs. By using a crockpot (or slow cooker), the meatballs get time to soak up the flavors, becoming incredibly tender while staying juicy.
Not only is this dish delicious, but it’s also incredibly convenient. The crockpot does all the hard work for you, making this a great recipe for busy days when you want a satisfying meal without too much hands-on cooking.
Ingredients List for Crockpot French Onion Meatballs
To prepare these delicious meatballs, you’ll need the following ingredients:
For the Meatballs:
- 1 lb ground beef (you can also use pork, chicken, or turkey)
- ½ cup breadcrumbs (Italian-style or plain)
- ¼ cup grated Parmesan cheese
- 1 large egg
- 2 tablespoons fresh parsley, chopped
- 2 cloves garlic, minced
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ¼ cup milk
For the French Onion Sauce:
- 2 large onions, thinly sliced
- 2 tablespoons unsalted butter
- 4 cups beef broth (low sodium if preferred)
- ½ teaspoon dried thyme
- ½ teaspoon sugar (to help caramelize the onions)
- 1 tablespoon Worcestershire sauce
- ¼ cup white wine (optional)
- Salt and pepper to taste
- 1 ½ cups shredded Gruyère or Swiss cheese (for topping)
Substitutions and Variations
This recipe is highly customizable depending on your dietary needs and preferences:
- Ground Meat: Swap the beef for ground turkey, chicken, or pork for a leaner or different flavor profile.
- Cheese: Gruyère and Swiss are traditional choices for French onion flavors, but mozzarella or provolone can work if you prefer a milder cheese.
- Gluten-Free: Use gluten-free breadcrumbs, and check your beef broth to make sure it’s gluten-free.
- Onions: While yellow onions are classic for French onion soup, you can use white or red onions for a slightly different taste.
- Alcohol-Free: Simply omit the wine and add a bit more beef broth.
Feel free to get creative with the spices and herbs as well. A little oregano or basil can add another dimension to the dish, while hot sauce or chili flakes can spice things up if you like a bit of heat.
Step-by-Step Cooking Instructions

Now that we have all the ingredients ready, let’s dive into the cooking process. The key to making perfect Crockpot French Onion Meatballs lies in layering flavors and giving everything enough time to develop while simmering in the slow cooker.
Step 1: Prepare the Meatballs
- Combine Ingredients: In a large bowl, mix together the ground beef, breadcrumbs, Parmesan cheese, egg, parsley, garlic, salt, pepper, and milk. Use your hands to gently combine everything, but avoid overmixing, as this can make the meatballs tough.
- Form Meatballs: Roll the meat mixture into 1-inch balls. You should get about 20-24 meatballs depending on the size. Place them on a plate or tray, ready for cooking.
Step 2: Brown the Meatballs (Optional but Recommended)
While browning the meatballs is optional, it adds extra flavor and helps them hold together better. If you have the time:
- Heat 1-2 tablespoons of oil in a skillet over medium heat.
- Add the meatballs in batches, cooking until browned on all sides (about 4-5 minutes).
- Transfer the browned meatballs to a paper towel-lined plate to drain any excess oil.
Step 3: Caramelize the Onions
- In a large skillet, melt butter over medium-low heat. Add the sliced onions and stir occasionally.
- Sprinkle in the sugar and a pinch of salt to help with the caramelization.
- Cook the onions for about 20-25 minutes, stirring frequently, until they are soft, golden, and caramelized.
Step 4: Assemble the Crockpot
- Add the caramelized onions to the bottom of the crockpot.
- Pour in the beef broth, Worcestershire sauce, thyme, white wine (if using), and season with salt and pepper.
- Gently place the meatballs into the broth and onions, ensuring they are submerged in the liquid.
Step 5: Cook the Meatballs
- Set your crockpot to low heat and cook for 6-8 hours, or set it on high for 3-4 hours.
- About 30 minutes before serving, sprinkle the shredded Gruyère or Swiss cheese over the meatballs and let it melt into the sauce.

Let’s recap the cooking process in short, actionable steps:

Common Mistakes to Avoid
- Overmixing the Meatball Mixture: Be gentle when mixing the meatball ingredients. Overworking the mixture can lead to dense, tough meatballs.
- Skipping the Caramelization: Don’t rush the onions! Properly caramelized onions give this dish its iconic sweet-savory flavor.
- Not Browning the Meatballs: While not essential, browning the meatballs adds extra depth of flavor and helps lock in moisture.
- Under-seasoning: Taste the broth as you go and adjust the seasoning accordingly. The combination of onions, beef broth, and Worcestershire sauce should be rich and flavorful.
