How to Make Crock Pot French Onion Meatballs
Step 1: Prepare the Onions
Start by placing those lovely sliced onions at the bottom of your 6-quart crock pot. This step is key because as they cook, they’ll soften and release their natural sweetness, which will infuse your dish with incredible flavor.
Step 2: Layer in the Meatballs
Next, pour those frozen meatballs over the onions. No need to thaw them first! They’ll cook perfectly in the broth while absorbing all those wonderful onion flavors.
Step 3: Create Your Flavorful Sauce
In a medium bowl, whisk together the beef broth, brown gravy mix, minced garlic, black pepper, dried thyme, and white grape juice vinegar until well combined. Pour this luscious mixture over the meatballs. The broth keeps everything moist while adding depth to each bite.
Step 4: Let It Cook
Cover your crock pot and let it work its magic! Cook on high for 2½-3½ hours or low for 5-6 hours. This slow cooking allows all those flavors to meld beautifully together.
Step 5: Thicken & Add Cheese
In a small bowl, whisk together cornstarch and water until smooth. Pour this mixture over the meatballs and gently stir to combine. Topping with grated gruyere cheese is what takes this dish over the top—cook for another ten minutes until it’s all melty and delicious!
Step 6: Serve & Enjoy!
Finally, serve these tasty Crock Pot French Onion Meatballs over rice or mashed potatoes. Each bite is filled with cheesy goodness that everyone will love. Enjoy every moment with friends and family around the table!
