How to Prepare Crockpot French Onion Meatballs

Step 1: Blend Meatball Mixture

In a spacious mixing bowl, combine ground beef, bread crumbs, egg, onion soup mix, garlic powder, and Worcestershire sauce.

Use your hands to thoroughly mix and blend ingredients until well incorporated.

Roll the mixture into evenly sized meatballs, ensuring they are compact and uniform.

Step 2: Brown Meatballs

Heat a skillet over medium-high heat.

Carefully place meatballs into the hot pan, rotating them to achieve a golden-brown sear on all sides.

This step locks in flavor and creates a delicious exterior crust.

Transfer the browned meatballs to the crockpot.

Step 3: Create Flavor Base

Slice onions and caramelize them in the same skillet used for searing meatballs.

Pour beef broth into the crockpot, then gently arrange the caramelized onions and seared meatballs on top of the liquid.

Step 4: Slow Cook to Perfection

Cover the crockpot and set to low heat.

Allow meatballs to cook slowly for 4-6 hours.

This gentle cooking method ensures tender, juicy meatballs that are fully cooked through and packed with rich flavor.

Step 5: Add Cheesy Topping

During the final 30 minutes of cooking, sprinkle shredded cheese over the meatballs.

Let the cheese melt and become gooey, creating a luxurious finishing touch.

Step 6: Serve and Garnish

Carefully transfer meatballs to a serving platter.

Garnish with freshly chopped parsley for a burst of color and added freshness.

Serve hot and enjoy your delectable Crockpot French Onion Meatballs.
