How to Make Crock Pot French Onion Meatballs
Step 1: Prepare the Onions
Place the sliced onions in the bottom of your 6-quart crock pot. This step is essential because the onions will caramelize as they cook, creating a sweet base for our meatballs.
Step 2: Layer the Meatballs
Now, pour those frozen meatballs over the onions. No need to thaw them first; they’ll cook perfectly as everything simmers together!
Step 3: Mix the Sauce
In a medium bowl, combine the beef broth, gravy mix, minced garlic, black pepper, dried thyme, and white apple vinegar. Whisk until everything is well mixed. Pour this flavorful concoction over your meatballs—this is where the magic happens!
Step 4: Let It Cook
Cover your crock pot and set it on high for 2½-3½ hours or low for 5-6 hours. Cooking slowly allows all those delicious flavors to meld together beautifully.
Step 5: Thicken and Add Cheese
Once cooked, whisk together cornstarch and water in a small bowl before pouring it over the meatballs. Give everything a gentle mix until well combined. Finally, sprinkle grated gruyere cheese on top and let it cook for another ten minutes until it’s melty and delightful.
Step 6: Serve It Up!
Spoon those delicious meatballs over fluffy rice or creamy mashed potatoes. Sit back and enjoy every bite with family or friends—it doesn’t get much better than this!
