- 2 cups low sodium beef broth

Step-by-step instructions


Let’s dive into the easy steps to create this delicious dish:
- Start with the Meatballs: Place the frozen meatballs directly into your crock pot.
- Layer Aromatics: Top the meatballs with the sliced sweet onions and minced garlic.
- Whisk the Sauce: In a mixing bowl or large measuring cup, whisk together the beef broth, condensed French onion soup, balsamic vinegar, thyme, black pepper, and cornstarch until well combined.
- Combine Everything: Pour this savory mixture over the meatballs, onions, and garlic in the crock pot.
- Cook Low and Slow: Cover with the lid and cook on LOW for about 3-5 hours. Stir halfway through to ensure even heating and prevent sauce from burning at the bottom.
- Melt the Cheese: When ready to serve, sprinkle shredded Gruyere cheese over the meatballs and cover again. Cook for an additional 5-10 minutes, or until the cheese is fully melted.

Storage and reheating tips
After enjoying this tasty meal, you may have some leftovers (if you’re lucky). To keep them fresh, store any uneaten meatballs in an airtight container in the refrigerator for up to 3 days. When ready to eat, simply reheat in the microwave or on the stovetop over low heat until warmed through. If you want to save them for a longer period, consider freezing them. Just make sure to let them cool completely before placing them in a freezer-safe bag. They’ll last up to 3 months in the freezer.
Pro chef tips
To take your dish to the next level, consider these quick tips:
- If you prefer a thicker sauce, allow it to cook uncovered for the last 30 minutes.
- Feel free to add sliced mushrooms for an earthy twist.
- To enhance the flavor even further, sauté the onions and garlic in a bit of butter before adding them to the crock pot. This releases more sugars and adds depth to the dish.
Creative twists
Looking to switch things up? Here are a few variations you can try:
- Use a mix of beef and pork meatballs for a more complex flavor.
- Swap the Gruyere cheese for a sharp cheddar or a creamy blue cheese for new taste dimensions.
- For a lighter option, substitute turkey or chicken meatballs, and use vegetable broth for a healthier twist.
