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 crucial because it creates a flavorful base that will infuse into the meatballs as they cook. Onions become sweet and tender over time, adding depth to our dish.
Step 2: Layer the Meatballs
Next, pour those frozen meatballs right over the onions. No need to thaw them! The slow cooking will ensure they heat through perfectly while absorbing all that lovely onion flavor.
Step 3: Mix Your Sauce
In a medium bowl, combine beef broth, gravy mix, minced garlic, black pepper, dried thyme, and white grape juice vinegar. Whisk until everything is well blended. Pour this mixture over your meatballs—this is what makes them juicy and packed with flavor!
Step 4: Set It to Cook
Cover your crock pot and set it to cook on high for 2½-3½ hours or low for 5-6 hours. This slow cooking method allows all those flavors to meld together beautifully. You can go about your day knowing dinner is taken care of!
Step 5: Thicken & Cheese Time
Once cooked, whisk together cornstarch and water in a small bowl before pouring it over the meatballs. Give everything a good mix to ensure it thickens nicely. Top with grated gruyere cheese and let it cook for another ten minutes until melted. The gooey cheese adds such an irresistible touch!
Step 6: Serve & Enjoy!
Finally, serve these delicious meatballs over rice or mashed potatoes. Watch as everyone savors each bite! Enjoy this cozy meal with family or friends—it’s sure to become a beloved staple in your home!
Pro Tips for Making Crock Pot French Onion Meatballs
Making Crock Pot French Onion Meatballs is a breeze, but a few tips can take your dish to the next level!
-
Sauté the onions first: Sautéing the onions until they’re golden brown enhances their sweetness and adds depth to the overall flavor of the dish.

Use high-quality meatballs: Opting for premium frozen meatballs can significantly improve the taste and texture. Look for ones made with lean beef or plant-based options if you prefer.
-
Adjust seasoning to taste: Don’t hesitate to tweak the black pepper and thyme according to your preference. A little more garlic can also amplify the flavor!

Let it rest before serving: Allowing the meatballs to sit for a few minutes after cooking helps them absorb the sauce better, enhancing their flavor profile even more.
