Step‑by‑Step Instructions for Crock Pot French Onion Meatballs

Step 1: Prepare the Onions
Begin by slicing the medium yellow onions thinly and layer them evenly at the bottom of your 6-quart crock pot. This layer acts as a flavorful base that will caramelize beautifully during cooking. The onions should be translucent and aromatic by the end of the cooking process, enhancing the overall flavor of your Crock Pot French Onion Meatballs.

Step 2: Add the Meatballs
Next, take the frozen meatballs and arrange them on top of the sliced onions in the crock pot. This ensures that the meatballs cook evenly and absorb the savory flavors from the onions below. You want to use about 26 ounces of meatballs, allowing them to become heated through and tender over the cooking time.

Step 3: Mix the Sauce Ingredients
In a separate bowl, combine 2 cups of low-sodium beef broth, 1 ounce of brown gravy mix, 2 teaspoons of minced garlic, 1 teaspoon of black pepper, and 1 teaspoon of dried thyme. Add 1 tablespoon of white wine vinegar and ¼ cup of water, then whisk everything together until smooth. This aromatic mixture will be poured over the meatballs and onions, creating a delicious sauce.

Step 4: Pour and Cook
Once your sauce is ready, pour it evenly over the meatballs and onions in the crock pot. Cover the crock pot securely with the lid and set it to cook on high for 2½ to 3½ hours or on low for 5 to 6 hours. You’ll know it’s done when the sauce has thickened and the meatballs are heated through; they should be tender and infused with the rich flavors of the sauce.

Step 5: Thicken the Sauce
After the cooking time has elapsed, whisk together 2 tablespoons of cornstarch with the reserved ¼ cup of water until it forms a slurry. Pour this mixture over the meatballs and stir gently to distribute evenly. This step will help achieve a thicker, more luxurious sauce that clings beautifully to your Crock Pot French Onion Meatballs.

Step 6: Add the Gruyere Cheese
Finally, sprinkle 1½ cups of grated Gruyere cheese over the meatballs and cover the crock pot again. Cook for an additional 10 minutes on high, or until the cheese has melted and becomes gooey. The melted Gruyere will add a creamy, nutty flavor that enhances the overall dish, making it even more irresistible.

Step 7: Serve and Enjoy
Once the cheese has melted, your Crock Pot French Onion Meatballs are ready to be served! You can dish them out over a comforting bed of mashed potatoes, rice, or noodles for a hearty meal. Alternatively, use toothpicks to serve them as delightful appetizers for gatherings, allowing everyone to savor this comforting dish.

Make Ahead Options

These Crock Pot French Onion Meatballs are perfect for busy weeknights! You can prepare the sauce (excluding the cheese) and store it in the refrigerator up to 3 days before cooking. Just mix the ingredients and refrigerate in an airtight container, as this helps the flavors meld beautifully. Additionally, you can layer the onions and frozen meatballs in the crock pot and cover it, refrigerating for up to 24 hours until you’re ready to cook. When you’re ready to serve, simply pour the prepared sauce over the meatballs, cook according to the original instructions, and add the Gruyere cheese in the last 10 minutes for that gooey, delicious finish. This way, you’ll have a comforting meal ready with minimal effort!

If you find your sauce is thinner than you’d like, don’t worry! Simply whisk together 2 tablespoons of cornstarch with a little water to create a slurry. Stir this mixture into the sauce and allow it to cook for an additional 10-15 minutes on high, which should thicken it right up.
