These keto meatballs in tomato sauce are one of my family’s regulars. It’s easy to prepare (even with kids), it tastes delicious and it’s full of nutrients. One portion has a total of 8 grams of net carbs.
I used to make tomato sauce with a bechamel sauce, made with flour, to prepare the tomato sauce. Ever since I went gluten-free and low carb, I needed to find a way to make a tomato sauce that was nice and thick but also tasted good of course.
You can use regular tomato sauce without added sugars to make it really really simple, but I’m a foodie, so for me, I like to add in some extra vegetables and spices.

For the ingredients
Ground beef: I like to use organic grass-fed, grass-finished ground beef because this meat is free of antibiotics and hormones and it’s higher in nutrients. But you can use any of your preferred ground meats such as pork, chicken, lamb, etc.
Coconut oil: I used coconut oil to sautee the onion, garlic, and bell pepper. You can use any of your preferred healthy cooking fats.
Chopped tomatoes: For the tomato sauce I used organic chopped tomatoes from a can. You can also use any other tomato sauce without added sugars. Make sure to check the ingredient list. It should only have tomatoes listed.
The spices: I like to use the basics like salt and pepper but also cumin, paprika powder, and dried oregano. These spices taste so good combined with ground meats and tomato sauces.

Tips for making the keto meatballs in tomato sauce
I used an air fryer to prepare the meatballs. If you don’t have an air fryer, you can just bake them in a pan with some coconut oil until they start to brown. To get them nicely baked on the inside, you can let them simmer in the tomato sauce for a few minutes before serving.
To blend the tomato sauce I used an immersion blender. If you don’t have an immersion blender, you can also transfer the tomato sauce to a regular blender and then transfer it back into the pot.
