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 creates a sweet base that enhances the flavors of the meatballs above them. The slow cooking process will caramelize the onions beautifully!
Step 2: Layer the Meatballs
Next, pour those frozen meatballs over the onions. They will soak up all that savory goodness from the broth and seasoning as they cook.
Step 3: Mix the Sauce
In a medium bowl, combine beef broth, brown gravy mix, minced garlic, black pepper, dried thyme, and white apple vinegar. Whisk until everything is well blended. This sauce is what makes your meatballs so flavorful!
Step 4: Pour Over Meatballs
Carefully pour your sauce mixture over the meatballs in the crock pot. Cover it up and let it cook on high for about 2½-3½ hours or low for 5-6 hours. The longer they cook, the more tender they’ll be!
Step 5: Thicken & Add Cheese
In a small bowl, whisk together cornstarch and water until smooth. Pour this mixture over your meatballs and stir gently to combine. Then sprinkle with grated gruyere cheese on top and let it cook for an additional ten minutes until melted. Trust me; this is where all the magic happens!
Step 6: Serve & Enjoy
Once everything is ready, serve your delicious Crock Pot French Onion Meatballs over rice or mashed potatoes. Gather around the table with family or friends and enjoy every bite of this comforting dish!
Pro Tips for Making Crock Pot French Onion Meatballs

Use Thawed Meatballs: If you have time, thawing the meatballs before cooking helps them cook more evenly and absorb more flavor from the broth.

Customize Your Cheese: While Gruyere cheese is delicious, feel free to mix it up with mozzarella or provolone for a different flavor profile. Each cheese melts beautifully and brings its own unique taste.
-
Add More Veggies: For a heartier meal, consider adding sliced bell peppers, mushrooms, or even carrots. They not only enhance the flavor but also boost the nutritional value.
-
Adjust Seasonings to Taste: Every palate is different! Don’t hesitate to tweak the garlic, thyme, or pepper according to your preference. A little experimentation can lead to delightful surprises!
