Ingredients You’ll Need

These ingredients are straightforward but essential for layering the complex, rich flavors that define Crock Pot French Onion Meatballs. Each component plays a vital role from tenderizing the meatballs to creating that perfect savory gravy that coats every bite.

• 2 medium yellow onions (sliced): They bring sweet depth and a tender texture as they slowly cook down in the crockpot.
• 26 ounces frozen meatballs: The star protein, conveniently pre-made to save time without sacrificing flavor.
• 2 cups low-sodium beef broth: Provides a rich base for the sauce and helps meld all flavors beautifully.
• 1 ounce package brown gravy mix: Adds thickness and hearty flavor to the savory sauce.
• 2 teaspoons garlic (minced): For aromatic warmth and a flavor kick that complements the onions.
• 1 teaspoon black pepper: Adds just enough spice to balance the sweetness and richness.
• 1 teaspoon dried thyme: A classic herb that pairs perfectly with beef and onions, uplifting the dish with subtle earthiness.
• 1 tablespoon white wine vinegar: Introduces a gentle tang that brightens and balances the savory flavors.
• ¼ cup water: Used to mix with cornstarch, helping to thicken the sauce perfectly.
• 2 tablespoons corn starch: Essential for achieving the gravy’s silky, luscious texture.
• 1½ cups gruyere cheese (grated): Melts into a gooey, nutty topping that brings a luxurious finish to the meatballs.

How to Make Crock Pot French Onion Meatballs

Step 1: Layer the Onions and Meatballs

Start by placing the thinly sliced yellow onions at the bottom of your crock pot. This layer forms the flavorful foundation as the onions slowly soften and sweeten during cooking. Next, scatter the frozen meatballs evenly over the onions, ensuring they’re nestled gently for even cooking and absorption of all those wonderful onion flavors.

Step 2: Mix and Pour the Flavorful Sauce

In a medium bowl, whisk together the beef broth, brown gravy mix, minced garlic, black pepper, dried thyme, and white wine vinegar. This combination creates a beautifully balanced savory sauce with hints of herbaceous depth and slight acidity to awaken your palate. Pour this mixture evenly over the meatballs, allowing the flavors to seep deep into the dish during cooking.

Step 3: Slow Cook the Meatballs to Tender Perfection

Cover your crock pot and cook on high for 2½ to 3½ hours, or on low for 5 to 6 hours. This slow cooking lets the onions caramelize gently while the meatballs cook through and soak up the rich, flavorful broth. The patience here pays off with tender, melt-in-your-mouth meatballs and a thickened, deeply flavored sauce.

Step 4: Thicken the Sauce and Add Cheese

Whisk the cornstarch and water in a small bowl until smooth, then pour it over the meatballs and stir gently to combine. This will thicken the sauce to a luxurious gravy consistency. Next, sprinkle the grated gruyere cheese evenly on top and cook uncovered for an additional 10 minutes or until the cheese has melted beautifully, creating a rich, gooey topping.

Step 5: Serve and Enjoy

Once your Crock Pot French Onion Meatballs are bubbling and golden with melted cheese, they’re ready to serve hot. This is when the magic of the flavors comes together in every bite – savory meat, sweet onions, melty cheese, and that irresistible gravy all in one comforting dish.

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer any leftover Crock Pot French Onion Meatballs to an airtight container and refrigerate. They’ll keep well for 3 to 4 days, and the flavors often deepen after resting, making the leftovers even more delicious.

Freezing

If you want to save some for later, freeze the meatballs along with sauce in a freezer-safe container or bag. They will maintain their taste and texture for up to 3 months. Be sure to label and date your container for easy identification.

Reheating

To reheat, thaw frozen meatballs overnight in the refrigerator, then warm gently in a saucepan over medium heat, stirring occasionally to prevent sticking. Alternatively, microwave until hot in short bursts. If refrigerated, simply reheat in the microwave or on the stovetop until warmed through, and enjoy as if freshly made.

FAQs

Can I use homemade meatballs instead of frozen?

Absolutely! Homemade meatballs work wonderfully and add a personal touch. Just make sure they are pre-cooked so they hold together well during crock pot cooking.

Yes, you can adapt it by using your Instant Pot’s sauté and slow cook functions, but be mindful of cooking times to avoid overcooking the meatballs.

You could substitute plant-based meatballs and use vegetable broth instead of beef broth; the flavor profile will differ, but it will still be tasty and comforting.
