How to Slow-Cook French Onion Meatballs in a Crock Pot

Step 1: Prepare Flavor-Packed Meatball Mixture

• Ground beef
• Breadcrumbs
• Parmesan cheese
• Egg
• Milk
• Garlic powder
• Onion powder
• Thyme
• Salt
• Black pepper

In a spacious mixing bowl, blend all ingredients gently. Use your hands to combine the components until they just come together. Avoid overmixing, which can make the meatballs tough and dense.

Step 2: Shape Perfectly Sized Meatballs

Roll the meat mixture into compact spheres approximately 1 inch in diameter. Aim for consistent sizing to ensure even cooking. Pro tip: Slightly dampen your hands with water to prevent the mixture from sticking while forming meatballs. You should be able to create around 20-24 uniformly shaped meatballs.

Step 3: Prepare Crock Pot Base

• Sliced onions
• Beef broth
• Worcestershire sauce
• Dried thyme

Layer sliced onions across the bottom of your slow cooker. Pour beef broth and Worcestershire sauce over the onions, creating a flavorful liquid foundation for the meatballs.

Step 4: Nestle Meatballs in Cooking Liquid

Gently place the formed meatballs into the crock pot, ensuring they sit atop the onion and broth mixture. Sprinkle dried thyme across the top for an extra layer of aromatic flavor.

Step 5: Slow Cook to Perfection

Cover the crock pot and set to low heat. Allow meatballs to simmer and cook for 6-7 hours, letting the flavors meld and the meat become incredibly tender.

Step 6: Add Cheesy Finishing Touch

During the final 30 minutes of cooking, sprinkle shredded Gruyère or Swiss cheese over the meatballs. Let the cheese melt and create a golden, bubbling crust that captures the essence of classic French onion soup.

Step 7: Serve and Enjoy

Carefully transfer meatballs to a serving platter. Spoon extra onion broth over the top and garnish with fresh chopped parsley. Serve alongside crusty bread or over creamy mashed potatoes for a complete meal.

Tips for Juicy Meatballs and Rich Onion Sauce

• Prevent Overworking Meat: Gently mix ingredients to keep meatballs tender and juicy, avoiding tough and dense texture.
• Uniform Size Matters: Use a small ice cream scoop or tablespoon to create consistent meatballs that cook evenly in the crock pot.
• Enhance Flavor Depth: Consider sautéing onions before adding to the crock pot to develop a richer, more caramelized taste profile.
• Trim Extra Fat: Choose lean ground beef (90/10 or 85/15) to reduce greasiness and ensure a cleaner, more appetizing final dish.
• Dairy-Free Adaptation: Swap Parmesan cheese with nutritional yeast and use a plant-based milk alternative for lactose-intolerant guests.

Storing and Reheating French Onion Meatballs Made

• Store leftover meatballs in an airtight container within 2 hours of cooking. Keep them fresh in the fridge for 3-4 days.
• Place cooled meatballs in a freezer-safe container or ziplock bag. They'll stay delicious for up to 3 months when properly sealed.
• Warm meatballs at 350°F for 10-15 minutes, ensuring they reach an internal temperature of 165°F. Cover with foil to prevent drying out.
• Zap meatballs in 30-second intervals, stirring between each to distribute heat evenly. Stop when they're steaming hot throughout.
