How to Make Crock Pot French Onion Meatballs
Step 1: Prepare the Base
Start by placing the sliced onions in the bottom of your 6-quart crock pot. The onions will caramelize beautifully as they cook, adding rich flavor to our dish. Then, pour those frozen meatballs right on top! No need to thaw; they’ll cook perfectly in the broth.

Step 3: Let It Cook
Cover your crock pot and set it to cook on high for 2½ to 3½ hours or low for 5 to 6 hours. This slow cooking allows all those flavors to meld beautifully while keeping the meatballs juicy.
Step 4: Thicken and Cheese It Up
In a small bowl, whisk together cornstarch and water until smooth. Pour this mixture over the meatballs and give everything a gentle stir to combine. Top with grated gruyere cheese and let it cook for another ten minutes until deliciously melted.
