Step-by-Step Cooking Instructions

Follow these steps to make delicious Crockpot French Onion Meatballs:
- Prepare the Meatballs:
- In a large bowl, combine the ground beef, breadcrumbs, egg, minced garlic, Worcestershire sauce, onion powder, salt, pepper, and parsley (if using). Mix gently until everything is combined but don’t overwork the meat.
- Roll the mixture into 1-inch meatballs and place them on a plate or baking sheet. You should get about 20-24 meatballs.
- Brown the Meatballs (Optional):
- Heat a tablespoon of olive oil in a skillet over medium-high heat. Brown the meatballs for 2-3 minutes on each side, just until they have a nice golden crust. This step is optional but adds extra flavor. Once browned, transfer the meatballs to your crockpot.
- Caramelize the Onions:
- In the same skillet, melt the butter over medium heat. Add the sliced onions and cook, stirring occasionally, for 10-15 minutes, until the onions are soft and caramelized. Add the minced garlic, balsamic vinegar, sugar (if using), thyme, and oregano. Cook for another 1-2 minutes until fragrant.
- Prepare the French Onion Sauce:
- Add the caramelized onions to the crockpot over the meatballs. Pour in the beef broth, Worcestershire sauce, and season with salt and pepper. Gently stir everything together to combine.
- Slow Cook the Meatballs:
- Cover the crockpot and cook on low for 4-5 hours or high for 2-3 hours, until the meatballs are fully cooked and tender, and the sauce is rich and flavorful.
- Add Cheese:
- About 10-15 minutes before serving, sprinkle the shredded Gruyère or Swiss cheese over the meatballs in the crockpot. Cover and let the cheese melt.
- Serve:
- Once the cheese has melted, spoon the meatballs and sauce over mashed potatoes, rice, or crusty bread. Garnish with fresh parsley for a pop of color and extra flavor.
How to Cook Crockpot French Onion Meatballs: A Step-by-Step Guide
- Step 1: Prepare the Meatballs
Start by mixing the ground meat with breadcrumbs, egg, and seasonings. Roll the mixture into meatballs about 1 inch in diameter. - Step 2: Brown the Meatballs (Optional)
Browning the meatballs adds extra flavor, but if you’re short on time, you can skip this step and place the raw meatballs directly into the crockpot. - Step 3: Caramelize the Onions
Caramelizing the onions adds the deep, rich flavor that’s iconic in French onion soup. Take your time to cook the onions until they’re soft and golden brown. - Step 4: Slow Cook Everything Together
Add the meatballs and onions to the crockpot along with the broth and seasonings. Let everything slow cook until the meatballs are tender and the sauce is rich. - Step 5: Melt the Cheese
Just before serving, sprinkle the shredded cheese over the meatballs and let it melt for that classic French onion soup touch.
Common Mistakes to Avoid
- Skipping the Onion Caramelization: Don’t rush the onions! Properly caramelizing the onions is essential for building the deep, sweet, and savory flavors in this dish.
- Overworking the Meat: When mixing the meatball ingredients, be gentle. Overworking the meat mixture can result in tough, dense meatballs.
- Not Browning the Meatballs: While browning the meatballs is optional, it adds a rich, caramelized flavor that takes this dish to the next level.
