How to Make Crock Pot French Onion Meatballs
Step 1: Prepare the Onions
Start by placing your sliced onions in the bottom of your 6-quart crock pot. This layered approach helps them become beautifully caramelized as they cook with the meatballs above. The sweetness from the onions will infuse into every bite!
Step 2: Add Your Meatballs
Now, gently pour frozen meatballs over the onions. No need to thaw them first; they’ll cook perfectly in the crock pot!
Step 3: Mix Your Sauce
In a medium bowl, combine beef broth, brown gravy mix, minced garlic, black pepper, dried thyme, and white grape juice vinegar. Whisk until everything is well combined. Pour this savory mixture over the meatballs—this step adds incredible depth of flavor!
Step 4: Cook Low and Slow
Cover your crock pot and choose your cooking time: high for 2½-3½ hours or low for 5-6 hours. Letting it cook low and slow allows all those flavors to meld beautifully.
Step 5: Thicken It Up
In a small bowl, whisk together cornstarch and water until smooth. Pour this mixture over the meatballs and stir gently until everything is mixed well. Then sprinkle grated gruyere cheese on top and cook for another ten minutes or until it’s melted and bubbly.
Step 6: Serve and Enjoy!
You’re ready to dig in! Serve your Crock Pot French Onion Meatballs over rice or creamy mashed potatoes. Enjoy every cheesy bite with family and friends!
