• 1 teaspoon dried thyme: Brings a subtle earthiness that pairs perfectly with onions and beef.
• 1 tablespoon white wine vinegar: A splash to brighten and elevate the flavor profile.

How to Make Crock Pot French Onion Meatballs

Step 1: Layer the Onions and Meatballs

Start by placing the sliced yellow onions in the bottom of your 6-quart crock pot. They will slowly caramelize and impart that wonderful sweetness and depth as they cook. Next, carefully pour the frozen meatballs over the onions, giving them a chance to soak up the savory goodness from the start.

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 until everything is well combined. Pour this mixture evenly over the meatballs and onions. This flavorful liquid will slowly reduce and thicken as it cooks, wrapping every meatball in tasty, savory gravy.

Step 3: Slow Cook to Perfection

Cover the crock pot and set it to cook on high for 2½ to 3½ hours or on low for 5 to 6 hours. The slow cooking process ensures the meatballs become tender and juicy while the onions melt into the base of the sauce, creating a rich and comforting dish.

Step 4: Thicken the Gravy and Add Cheese

In a small bowl, whisk together the corn starch and water until smooth, then pour this slurry into the crock pot. Stir gently to combine and sprinkle the grated gruyere cheese over the top. Cover and cook for an additional 10 minutes until the cheese is melted and bubbly, enhancing the dish’s creaminess and adding a delightful cheesy crust.

How to Serve Crock Pot French Onion Meatballs

Garnishes

For a pop of color and freshness, sprinkle freshly chopped parsley or thyme over the meatballs just before serving. These bright herbs enhance the dish with a subtle flourish and make it look as good as it tastes.

Side Dishes

Crock Pot French Onion Meatballs are perfectly paired with creamy mashed potatoes or fluffy white rice to soak up every bit of that rich gravy. Steamed green beans or a crisp side salad can add a refreshing contrast to the hearty meatballs and melted cheese.

Creative Ways to Present

Make Ahead and Storage

Storing Leftovers

Once cooled, store any leftovers in an airtight container and refrigerate for up to 3 days. The flavors deepen overnight, so leftovers taste even better the next day!

Freezing

If you want to keep Crock Pot French Onion Meatballs for longer, freeze them in a freezer-safe container for up to 3 months. Just be sure to cool the dish completely before freezing to maintain the best texture and flavor.

Reheating

To reheat, thaw frozen meatballs overnight in the fridge if needed. Warm gently in a saucepan over low heat, stirring occasionally, to bring back that rich, cheesy goodness without drying out the meatballs.
