Description

These Crock Pot French Onion Meatballs are a savory and mouthwatering dish that combines classic French onion flavors with tender meatballs, all cooked to perfection in a slow cooker. The caramelized onions, rich broth, and gooey cheese make this a comforting and delicious meal or appetizer.


Ingredients

Scale

For the Caramelized Onions:

  • 2 tablespoons butter
  • 2 large yellow onions, thinly sliced
  • 1 teaspoon sugar
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 2 cloves garlic, minced

For the Meatballs:

  • 1 tablespoon Worcestershire sauce
  • 1 tablespoon balsamic vinegar
  • 1 can (10.5 oz) condensed French onion soup
  • 1 tablespoon cornstarch mixed with 2 tablespoons water (optional, for thickening)
  • 2 lbs frozen fully-cooked meatballs
  • 1 cup shredded Gruyère or Swiss cheese
  • 2 tablespoons chopped fresh parsley, for garnish


Instructions

  1. Caramelize the Onions: In a large skillet over medium heat, melt the butter. Add sliced onions, sugar, salt, and pepper, and sauté for 20–25 minutes until caramelized and golden brown. Add garlic and cook for another minute.
  2. Prepare the Sauce: Stir in Worcestershire sauce, balsamic vinegar, and French onion soup in the skillet, scraping up any browned bits. Transfer the mixture to a slow cooker.
  3. Cook the Meatballs: Add the frozen meatballs to the slow cooker and stir to coat. Cover and cook on low for 4–5 hours or on high for 2–3 hours until heated through.
  4. Thicken the Sauce (optional): For a thicker sauce, stir in the cornstarch slurry during the last 30 minutes of cooking.
  5. Finish and Serve: Sprinkle cheese over the top of the meatballs, cover for 5–10 minutes to melt. Garnish with parsley before serving warm.

Notes

  • Great as a party appetizer or served over mashed potatoes, noodles, or crusty bread for a hearty meal.
  • Use homemade meatballs if preferred.
