Ingredients

Scale

Meatballs and Onion Base

  • 2 medium yellow onions, sliced
  • 26 ounces frozen meatballs

Broth and Seasoning

  • 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 wine vinegar

Thickener and Topping

  • ¼ cup water
  • 2 tablespoons corn starch
  • 1½ cups gruyere cheese, grated

Instructions

  1. Prepare the onions and meatballs: Place the sliced yellow onions evenly at the bottom of a 6-quart crock pot. Then, layer the frozen meatballs over the onions, creating a base for slow cooking.
  2. Mix and add the broth and seasonings: In a medium bowl, whisk together the low-sodium beef broth, package of brown gravy mix, minced garlic, black pepper, dried thyme, and white wine vinegar until thoroughly combined. Pour this mixture evenly over the meatballs in the crock pot.
  3. Cook the meatballs: Cover the crock pot with its lid and cook on high heat for 2½ to 3½ hours, or alternatively on low heat for 5 to 6 hours. This slow cooking allows the flavors to meld and the onions to soften beautifully.
  4. Thicken the sauce and add cheese: In a small bowl, whisk together the corn starch and water until smooth. Pour this slurry over the meatballs and stir gently to integrate. Then, sprinkle the grated gruyere cheese evenly on top. Cover and cook for an additional 10 minutes, or until the cheese is melted and bubbly.
  5. Serve: Once done, serve the French onion meatballs hot over steamed rice or creamy mashed potatoes for a satisfying and comforting meal. Enjoy!

Notes

  • You can substitute frozen meatballs with homemade or fresh ones for a more personalized taste.
  • For a deeper onion flavor, consider caramelizing the onions briefly on the stove before adding to the crock pot.
  • Make sure to whisk the cornstarch and water mixture well to avoid lumps when thickening the sauce.
  • Leftovers store well in the refrigerator for up to 3 days and reheat gently on the stove or microwave.
  • This dish pairs wonderfully with crusty bread to soak up extra sauce.
