This simple recipe for keto marinara uses canned plum tomatoes. It's a good low carb marinara sauce to serve with cheesy keto breadsticks.
If you are looking for a good homemade sugar-free marinara sauce, you'll be surprised how easy it is to make your own. This recipe is adapted from one found on a can of tomatoes.
The primary change from the original recipe was to eliminate the sugar and use a low carb sweetener instead. But I also found it tastes better with some Italian seasonings sprinkled in too.
You can omit the sweetener if you'd like. I only used ⅛ teaspoon of Pyure All Purpose. The tomatoes already have natural sugar so it's really not needed anyway.
This really is the perfect keto marinara sauce! It goes well with Fathead breadsticks or as a topping for spiralized zucchini.
I'm already planning to use the sauce with some homemade meatballs in the Instant Pot too!
How to make keto marinara sauce
There's only a few simple steps needed to make your own low carb pasta sauce!
- Sauté a few cloves of garlic in olive oil until golden brown. Then stir in a little tomato paste, continuing to cook for another minute.
- Add in a can of peeled plum tomatoes. If the tomatoes aren't already seasoned, you'll want to add in some Italian seasonings along with salt and pepper.
- Add in some fresh basil leaves. Simmer the sauce over low heat, stirring occasionally. Adjust seasonings if needed. Remove the basil leaves and garlic closed then pureé if desired.
That's all there is to making your own red sauce!
What marinara sauce is keto friendly?
As long as the sauce doesn't add sugar, any commercial brand should be acceptable. However, some brands have less carbs than others.
My favorite store bought sauce is Rao's as the carbs tend to be lower than others.
Carbs per serving
For each half cup serving, the total carbs are 5 grams with 1 gram of fiber. That's just 4g net carbs each!
Because of the olive oil, there's also some healthy fat too. I calculate about 7 grams of fat for each serving.
