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 important because as they cook, they will soften and release their natural sweetness, creating an incredible base flavor for your dish.
Step 2: Add the Meatballs
Next, pour those frozen meatballs right over the onions. No need to thaw them first! They will soak up all those delicious flavors as they cook low and slow.
Step 3: Mix the Sauce
In a medium bowl, combine beef broth, gravy mix, garlic, black pepper, dried thyme, and white grape juice vinegar. Whisk until everything is well mixed and then pour this flavorful concoction over your meatballs. This mixture is what gives our dish its rich depth!
Step 4: Let It Cook
Cover your crock pot and cook on high for 2½-3½ hours or low for 5-6 hours. The long cooking time allows all those wonderful flavors to meld together beautifully—trust me; it’s worth the wait!
Step 5: Thicken & Finish with Cheese
In a small bowl, whisk together cornstarch and water until smooth. Pour this mixture over the meatballs and stir gently until everything is combined. Lastly, sprinkle grated gruyere cheese on top and let it cook for an additional ten minutes until melty and golden!
Now you’re ready to serve your Crock Pot French Onion Meatballs over rice or mashed potatoes. Enjoy every bite!
Pro Tips for Making Crock Pot French Onion Meatballs
Making these meatballs is a breeze, but with a few handy tips, you can elevate them to the next level!
-
Use fresh onions: Freshly sliced onions will give your dish a sweeter and more robust flavor compared to pre-packaged versions. They enhance the overall taste of the meatballs.
-
Choose high-quality beef broth: A rich, low-sodium beef broth will make a significant difference in flavor. It adds depth without overwhelming the dish with saltiness.
-
Let it cook longer on low: If time allows, cooking on low for 6 hours will result in even more tender meatballs, allowing all the flavors to meld beautifully.
-
Experiment with cheese: While gruyere is delicious, feel free to mix it up! Cheddar or mozzarella can also provide wonderful flavors and textures that complement the meatballs.
-
Serve immediately for best results: These meatballs are best enjoyed right after they are cooked. The cheese is perfectly gooey, and the flavors are at their peak!
