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 crock pot. This layer will soak up all those delicious juices as they cook! The sweetness of the onions will enhance the overall flavor profile.
Step 2: Add the Meatballs
Next, pour those frozen meatballs right over the onions. It’s so easy! These meatballs will absorb all that onion goodness as they cook.
Step 3: Create the Sauce
In a medium bowl, combine your beef broth, brown gravy mix, minced garlic, black pepper, dried thyme, and white grape juice vinegar. Whisk them together until well blended. Pour this flavorful mixture over the meatballs. It’s crucial because this sauce infuses every bite with amazing flavor.
Step 4: Let It Cook
Cover your crock pot and set it on high for 2½-3½ hours or low for 5-6 hours. The longer it cooks, the more tender and flavorful everything becomes. Just imagine coming home to that wonderful aroma filling your kitchen!
Step 5: Thicken and Melt
In a small bowl, whisk together cornstarch and water until smooth. Pour this mixture over the meatballs after cooking time is up. Stir gently until combined. Now it’s time to sprinkle on that grated gruyere cheese! Cover again and let it cook for another ten minutes or until that glorious cheese has melted perfectly.
Step 6: Serve and Enjoy!
