Step-by-Step Cooking Instructions

These French Onion Meatballs are easy to prepare and can be cooked right in your slow cooker, making it a convenient, no-fuss meal.

How to Make Crockpot French Onion Meatballs: A Step-by-Step Guide

Step 1: Prepare the Meatballs

In a large bowl, combine the ground beef, breadcrumbs, grated Parmesan, egg, minced garlic, dried thyme, dried parsley, salt, and pepper. Mix everything together gently with your hands until fully combined.

Form the mixture into meatballs, about 1 to 1 ½ inches in diameter. You should get about 15-20 meatballs, depending on the size.

Pro Tip: Don’t overwork the meat mixture, as it can result in tough meatballs. Gently mix until just combined.

Step 2: Sear the Meatballs (Optional)

For added flavor, heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Sear the meatballs on all sides until browned, about 2-3 minutes per side. This step is optional but will help the meatballs hold their shape and add extra flavor.

Transfer the seared meatballs to the slow cooker.

Step 3: Caramelize the Onions

In the same skillet, melt 3 tablespoons of butter over medium heat. Add the thinly sliced onions and cook, stirring frequently, for about 15-20 minutes, until the onions are caramelized and golden brown. If the onions start to stick, add a splash of water or broth to deglaze the pan.

Once the onions are caramelized, add the minced garlic, Worcestershire sauce, and sugar (if using), and cook for another 1-2 minutes until fragrant.

Step 4: Prepare the French Onion Sauce

Add the caramelized onions and garlic mixture to the slow cooker with the meatballs. Pour in the beef broth and stir in the dried thyme, salt, and pepper.

Step 5: Slow Cook the Meatballs

Cover the slow cooker and cook on low for 4-6 hours or on high for 2-3 hours, until the meatballs are cooked through and the sauce is bubbling.

Step 6: Add the Cheese

About 15 minutes before serving, sprinkle the shredded Gruyère or Swiss cheese over the top of the meatballs in the slow cooker. Cover and cook for another 10-15 minutes, until the cheese is melted and bubbly.

Step 7: Serve and Garnish

Once the cheese is melted, your French Onion Meatballs are ready to serve! Garnish with fresh parsley if desired and serve with your favorite sides, such as mashed potatoes, rice, or crusty bread to soak up the delicious sauce.

Common Mistakes to Avoid

• Skipping the caramelization step: Caramelizing the onions is key to developing the rich, deep flavor of French onion soup. Don’t rush this step; it’s worth the time!
• Overcooking the meatballs: Be sure to cook the meatballs just until they’re done. Overcooking can cause them to dry out.
• Not browning the meatballs: While browning is optional, it adds flavor and helps the meatballs hold together during slow cooking.
