Crock Pot French Onion Meatballs Ingredients For the Meatballs • Frozen Meatballs (26 ounces) – The main protein source; opt for beef, turkey, or even homemade meatballs for a personal touch. For the Sauce • Medium Yellow Onions – Adds sweetness and depth; you can swap for white onions if you prefer a sharper flavor. • Low-Sodium Beef Broth (2 cups) – Provides that robust umami flavor; feel free to use vegetable broth for a lighter dish. • Brown Gravy Mix (1 ounce) – Enhances the richness of the sauce; homemade gravy can offer an even better taste. • Garlic (2 teaspoons, minced) – Adds aromatic flavor; fresh garlic is always recommended for the best results. • Black Pepper (1 teaspoon) – Provides a little kick; adjust according to your liking. • Dried Thyme (1 teaspoon) – Infuses a lovely herby note; if you have fresh thyme, use three times the amount for more flavor. • White Wine Vinegar (1 tablespoon) – Balances the richness of the dish; lemon juice can be substituted in a pinch. • Water (¼ cup) – Used for adjusting consistency; you can skip this if you’re using the appropriate amount of broth. • Corn Starch (2 tablespoons) – Helps thicken the sauce; arrowroot starch or additional gravy mix can work well, too. For the Topping • Gruyere Cheese (1½ cups, grated) – Offers a creamy and melty topping that takes these meatballs to the next level; Swiss cheese is a good alternative.

Step‑by‑Step Instructions for Crock Pot French Onion Meatballs Step 1: Prepare Onions Begin by slicing medium yellow onions into thin rounds. Layer them evenly in the bottom of a 6-quart crock pot, creating a sweet, aromatic base for your Crock Pot French Onion Meatballs.
