One-Pot Meatball Dinner
Meatball, potatoes, and vegetables. This Italian meatball dinner is the kind slow cooker recipe I love. No fuss, and everything cooks together for a true one-pot recipe. Using fresh homemade meatballs (or frozen), your favorite vegetable and a quick sauce made directly in the base of the slow cooker, this is a lot easier than it looks.
The Meatballs
If using the Instant Pot, you will need to brown the meatballs as instructed. If you’re using the slow cooker, you a few more options. I have made this recipe with the meatballs 3 different ways: once with meatballs that were completely raw, once with meatballs that were raw but frozen, and once with meatballs that were cooked and frozen. My final say is that they all pretty much taste the same! Which makes sense if you think about it. So really it will all depend on how much time you have. If you don’t have time to pre-cook your meatballs or freeze them, add them to the slow cooker raw. I used raw meatballs for the pics in this post.

I used my herb meatballs recipe because it’s both paleo and whole30 compliant. You do not have to use this recipe for your meatballs (although I love it). By all means, feel free to use your favorite meatball recipe if you have one. I made my meatballs a little larger than usual because I wanted them to all fit properly in the slow cooker along with the other ingredients. I would suggest making no more than 12 meatballs.
Fresh asparagus or green beans are my preferred vegetables for this. Having made this recipe using both fresh and frozen vegetables, I didn’t find much a difference in taste after it was slow cooked. Again, it will all depend on your preference. Other vegetables that you can use other than asparagus and green beans are broccoli, mushrooms, bell peppers, zucchini or even eggplant. You can use potatoes or sweet potatoes. I used yellow potatoes. Remove the potatoes all together and you have a low-carb meal. If you do make this low-carb, I suggest adding in more vegetables in addition to what the recipe calls for.
Don’t worry if all your food isn’t fully submerged in the tomato sauce. It doesn’t need to be to cook fully.

I’m so glad you enjoyed it!
I see you meatball recipe makes approx 20 meatballs. Do you make the full recipe of your meatballs for this recipe (just making the meatballs larger) or do you halve the meatball recipe?
You nailed it. I use my meatball recipe (https://fitslowcookerqueen.com/herbed-baked-meatballs/) but I make the meatballs larger than usual would.
I made this dish in my pressure cooker with sweet potatoes and it was so good! Thank you for sharing.
I’m so glad you enjoyed it!
