How to Make Keto Italian Sausage Meatball Casserole
This is just a quick overview of how to make the low carb meatball casserole. For the recipe in detail, scroll to the recipe card at the end of the post.

What Brand of Mild Italian Sausage Should I Use in my Keto Meatball Casserole?
For a budget-friendly option, I recommend using Johnsonville Mild All Natural Italian Ground Sausage. It is gluten-free, dairy-free, MSG-free, and contains no artificial colors, artificial flavors, nitrates, or nitrites. It does contain a tiny amount of sugar, but not enough to be harmful or to boost the carb content. (Bacon is the same way; nearly all brands contain a touch of sugar.)
If you want an entirely sugar-free option, I recommend Pederson’s No Sugar Ground Italian Sausage.
What Brand of Sugar-Free Marinara or Pasta Sauce Should I Use?
If you can find it, Rao’s Vodka Sauce is the best sauce for this recipe!
Second-best is Thrive Market’s Vodka Pasta Sauce.
If neither of those are readily available to you, any sugar-free sauce will suffice (check the labels and go for the lowest-carb option), but if the sauce you use doesn’t include parmesan and romano cheese, I recommend stirring in 1/4 cup parmesan and romano cheese to your sauce before adding it to to the recipe. This will add 26 calories, 1.5g fat, 2g protein, and 0g carbs to each serving.
