An easy no-cook keto marinara sauce that is loaded with flavor, not sugar! It’s the perfect low carb tomato sauce for pizza, zucchini noodles or spaghetti squash when you need a keto Italian fix!
I’m posting this really easy keto marinara sauce recipe because I’ll be including two recipes that call for it in next week’s 7 Day Keto Meal Plan.
Why make your own tomato sauce?
- Store bought jarred sauce is convenient, but almost always has added sugar and fillers that also add carbs.
- To get a good one like Rao’s that is tasty and healthy, it can cost as much $8 or more!
- Making homemade marinara sauce is easy and inexpensive!
Wanna know what else is crazy awesome about this Keto marinara sauce?
You don’t even need a pot to make this recipe!
I kid you not, I never cook this sauce before using it!
I do heat up this keto marinara sauce before eating it in a recipe, but I usually make it without simmering it at all beforehand. I find that the longer you cook a simple meatless tomato sauce like this one, the more flavor you lose.
I could literally drink this keto marinara sauce out of the container – that’s how flavorful it is!
My usual marinara sauce recipe contains a lot of onions and garlic, which can really bust your net carb budget for the day. So I’m giving you this super easy, and much lower in carbs, “no chop” keto marinara sauce that you can literally make in five minutes. Then freeze it in 1/2 cup portions for whenever you need it.
What are the best tomatoes to use in Marinara sauce?
The key to this delicious keto marinara sauce is to start with the best quality tomatoes. We always use certified San Marzano (the brand doesn’t matter) tomatoes, and it makes a world of difference. It costs a bit more per can, but since you don’t eat a ton of it on keto anyway, trust me it’s worth the price (and still cheaper than a decent store-bought marinara.)
Here’s an article that’s worth a read if you’re curious about What is So Special About San Marzano Tomatoes?
If you can’t find, or don’t want to pay for certified San Marzano tomatoes, then any no sugar added whole tomatoes will work in this keto marinara sauce – but the flavor won’t be as good.
Storage Information
This low carb tomato sauce will keep for a week in the fridge. I recommend making several batches and then freezing it in 1/2 cup portions for whenever you need it.

Easy Keto Marinara Sauce – Low Carb
- Total Time: 5 minutes
- Yield: 4 cups 1x
- Diet: Diabetic
Description
An easy keto marinara sauce for low carb pasta or pizza sauce!
Ingredients
- 28 oz can Peeled San Marzano Tomatoes (no sugar added)
- 1 tablespoon red wine vinegar
- 1/4 cup extra virgin olive oil
- 1/4 teaspoon black pepper
- 1/2 teaspoon red pepper flakes
- 1 teaspoon onion powder
- 1 teaspoon garlic powder
- 1 teaspoon dried basil
- 1 teaspoon dried oregano
- 1 teaspoon dried parsley
- 1 teaspoon kosher salt (add more if necessary)
Instructions
- Puree the tomatoes, olive oil, and 1/2 cup of the liquid from the can in a small blender or magic bullet.
- Stir in the remaining ingredients.
- Taste and adjust seasoning if necessary.
Notes
Tomatoes are a natural product and the flavor can vary. If you find your sauce isn’t naturally sweet enough, you can add 1 teaspoon of erythritol or another carb free sweetener of your choice if you aren’t on the Whole 30.
Don’t omit the juice from the tomatoes during pureeing or you’ll end up with less sauce – and your concentration of carbs will be higher per serving.

I love love love this recipe! I now have a garden and want to make some from fresh tomatoes and I have a ridiculous silly question. I’m new to canning, never done it. I want to make a bunch of this from my fresh tomatoes. Can it be canned? I assume I’d have to simmer it first.
Mellissa Sevigny says
Canning tomato sauce is possible but requires pressure canning to be safe from botulism I believe. Be very careful and do some research on safe canning practices before you try it. As an alternative this would freeze well for up to 6 months or so.

I love this recipe, I have used it since I found it on here. I tweaked it for me with adding more red pepper flakes, no red wine vinegar, adding sweetener and Greek oregano. Just for my taste. Thank you so much for this recipe.
Shari Ann says
Another 5 star recipe! I just used this marinara to make a zucchini lasagna that turned out to be out of this world delicious. And I attribute that largely to your marinara. My sisters and I all love your site – when we start talking about cooking, somebody will inevitably say ‘What’s Mellissa say about this?’, or “Did you look at Mellissa’s site?’, ‘I bet Mellissa has something.’ You’re like the 4th sister – we just love you.
Mellissa Sevigny says
I could not love this comment more Shari Ann, thank you! I am honored to be considered the 4th sister! 😘😘😘

Yummy! I will plan on using this one again! So much better than commercial sauces. I used fresh tomatoes that I got from Costco! I will do this one again! Kudos on a great recipe
Erin says
I love this sauce especially for homemade pizza, but whenever it’s thawed out from the freezer it’s too runny. Do you have a solution for this?
Tom Horsley says
Made this a while back, and I’ve found it seems to get even better after sitting in the fridge for a while. It really is wonderful sauce and I added no sweetener of any kind. It is tempting to just eat with a spoon :-). I’ve used it on low carb pizza, and I just made green beans with the sauce on them. Planning mozzarella chicken breasts in sauce later this week.
Bobbi says
This was great!!!. Was as easy as you said! I have never made marina before so you spoiled making it this way! Also been doing keto a few months, really needed this.
Alice says
Never knew marinara could be this easy. I had to improvise. All I had was petite diced tomatoes. I used those and skipped the blender step. Delish! Thanks for sharing😊
Stella says
I made this for my husband who’s doing Keto, but it’s so tasty and easy, I’m keeping it as my go-to marinara recipe. Thanks!
Genevieve says
I’m the only keto person in the house, and my husband has quite the sweet tooth. Could I make a big batch, take out some for myself, and then add brown sugar to the rest for everyone else? Does that work without cooking it? Thank you. ❤️
Denise says
I’ve used this recipe COUNTLESS times for everything from pizza sauce, to dipping sauce, to spaghetti sauce. It’s always delicious and super easy to make.
Danielle says
Just made. Will be made again- lovely
