Ingredients
Meatballs & Onions
- 2 medium yellow onions, sliced
- 26 ounces frozen meatballs
Sauce
- 2 cups low-sodium beef broth
- 1 ounce package brown gravy mix
- 2 teaspoons garlic, minced
- 1 teaspoon black pepper
- 1 teaspoon dried thyme
- 1 tablespoon white vinegar
Thickener & Topping
- ¼ cup water
- 2 tablespoons corn starch
- 1½ cups Gruyere cheese, grated
Instructions
- Layer Onions and Meatballs: Place the sliced yellow onions evenly on the bottom of a 6-quart crock pot. Then, evenly distribute the frozen meatballs over the top of the onions.
- Prepare and Add Sauce: In a medium bowl, whisk together the beef broth, brown gravy mix, minced garlic, black pepper, dried thyme, and white vinegar until the mixture is smooth and well combined. Pour this sauce mixture evenly over the meatballs in the crock pot.
- Cook the Meatballs: Cover the crock pot with its lid and cook on the high setting for 2½ to 3½ hours or on the low setting for 5 to 6 hours, until the meatballs are heated through and the onions are tender.
- Thicken Sauce and Add Cheese: In a small bowl, whisk together the cornstarch and water to create a slurry. Pour this mixture over the meatballs and stir gently until combined. Then, sprinkle the grated Gruyere cheese evenly on top and cover the crock pot again. Cook for an additional 10 minutes or until the cheese is melted and bubbly.
- Serve: Serve the French onion meatballs hot over rice, mashed potatoes, or your preferred side dish. Enjoy this hearty and cheesy meal!
Notes
- For best results, use low-sodium beef broth to control the saltiness of the dish.
- The cooking times can vary depending on your crock pot model; check meatballs for doneness before serving.
- Gruyere cheese can be substituted with Swiss or mozzarella if preferred.
- Leftovers can be refrigerated for up to 3 days and reheated gently on the stovetop or microwave.
- Serving over creamy mashed potatoes or buttery rice complements the rich gravy perfectly.
