How to Make Crock Pot French Onion Meatballs
Step 1: Prepare the Onions
Start by placing the sliced onions at the bottom of your 6-quart crock pot. This step is essential because cooking them slowly allows their natural sweetness to develop, creating that rich base flavor we love in French onion dishes.
Step 2: Layer in the Meatballs
Next, pour those frozen meatballs right on top of the onions. No need to thaw them first! They’ll cook perfectly in the slow cooker while soaking up all those delicious flavors.
Step 3: Mix the Sauce Ingredients
In a medium bowl, combine the beef broth, brown gravy mix, minced garlic, black pepper, dried thyme, and white grape juice vinegar. Whisk everything together until well combined, then pour this savory mixture over your meatballs. This sauce adds depth and richness to each bite!
Step 4: Let It Cook
Cover your crock pot and set it to cook on high for 2½-3½ hours or low for 5-6 hours. The longer it cooks, the more flavorful everything becomes! Just resist peeking too often—let those aromas build up!
Step 5: Thicken Up Your Sauce
Once cooking time is done, whisk together cornstarch and water in a small bowl. Pour this mixture over your meatballs and stir gently until everything is well coated. Then sprinkle on that glorious grated gruyere cheese! Cover again and let it cook for another ten minutes until that cheese is beautifully melted.
Step 6: Serve and Enjoy!
Finally, serve these decadent meatballs over rice or mashed potatoes for a hearty meal. Trust me; every bite will be worth it! Enjoy this comforting dish with family and friends; it’s sure to become one of your go-to recipes!
Happy cooking!
