Ingredient Substitutions & Additions

• Swap the beef: Ground turkey or chicken works great if you prefer a lighter option.

• Extra cheesy? Add a sprinkle of Parmesan on top for more depth of flavor.

How to Make Crock Pot French Onion Beef Meatballs

1. Prepare the Meatballs

In a large bowl, combine the ground beef, breadcrumbs, egg, and half of the French onion soup mix. Mix well until evenly combined, then roll into 1-inch meatballs.

2. Layer in the Crock Pot

Place the sliced onions at the bottom of the slow cooker, creating a flavorful base. Then, carefully place the meatballs on top.

3. Make the Broth Mixture

In a separate bowl, whisk together the beef broth, Worcestershire sauce, and remaining French onion soup mix. Pour this over the meatballs, ensuring they’re evenly coated.

4. Slow Cook to Perfection

Cover and cook on LOW for 4-5 hours or HIGH for 2-3 hours.

5. Add the Cheese

About 15 minutes before serving, sprinkle the shredded mozzarella and Swiss/Gruyère cheese over the meatballs. Cover again and let the cheese melt.

6. Garnish & Serve

Once the cheese is beautifully melted, sprinkle with fresh parsley for a pop of color and freshness.

Serve hot and enjoy every comforting, cheesy bite!

What to Serve with French Onion Meatballs

• Mashed potatoes: The creamy texture pairs perfectly with the rich onion broth.
• Egg noodles or pasta: A great option for soaking up all the delicious sauce.
• Rice: Simple and perfect for a complete meal.
• Crusty bread: Perfect for sopping up all that cheesy, oniony goodness!

Pro Tips for the Best Meatballs

• Don’t overmix! Overworking the meat mixture can make your meatballs tough. Mix just until combined.
• Use a cookie scoop: This makes forming the meatballs quick and easy!
• Brown the meatballs first (optional): If you want a deeper flavor, sear them in a skillet before adding them to the Crock Pot.
• Don’t skip the cheese! It’s what makes these meatballs extra indulgent and delicious.

How to Store & Reheat

• Refrigerate: Store leftovers in an airtight container for up to 4 days.
• Freeze: Let the meatballs cool completely, then freeze in a sealed container for up to 3 months.
• Reheat: Warm in the microwave or on the stovetop with a splash of beef broth to keep them moist.
