An easy no-cook low carb marinara sauce that is loaded with flavor, not sugar! It’s the perfect keto tomato sauce for Fathead Pizza, or to serve with zucchini noodles or spaghetti squash when you need a keto pasta fix!
I’m posting this really easy low carb marinara sauce recipe because I’ll be including two recipes that call for keto marinara sauce in next week’s 7 Day Keto Meal Plan. I will also update old posts to include a link to this recipe.
Why should you bother to make your own keto marina sauce?? Store bought jarred sauce is convenient, but almost always has added sugar and fillers. To get a good one that isn’t loaded with junk, it can cost as much $8 or more!
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” version that you can literally make in five minutes. Then freeze it in 1/2 cup portions for whenever you need it.
Wanna know what’s crazy awesome about this Keto marinara sauce?
YOU WON’T EVEN NEED A POT TO MAKE IT.
I kid you not, I never cook this sauce before using it! I heat it before eating it in a recipe, but I usually make it without simmering it at all. I find that the longer you cook a simple meatless sauce like this one, the more flavor you lose. I could literally drink this out of the container – that’s how flavorful it is!
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.)
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 recipe – but the flavor won’t be as good.

Easy Keto Marinara Sauce – Low Carb
- Prep Time: 5 minutes
- Cook Time: 0 minutes
- Total Time: 5 minutes
- Yield: 4 cups 1x
Description
An easy low carb recipe for keto marinara or pizza sauce!
Ingredients
- 28 oz can Peeled San Marzano Tomatoes (no sugar added)
- 1 Tbsp red wine vinegar
- 1/4 cup extra virgin olive oil
- 1/4 tsp black pepper
- 1/2 tsp red pepper flakes
- 1 tsp onion powder
- 1 tsp garlic powder
- 1 tsp dried basil
- 1 tsp dried oregano
- 1 tsp dried parsley
- 1 tsp 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.

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.
This sauce was not bad for being keto. I happen to like my sauce sweet, so I added about a tbsp os Swerve sweetener. And what made it very tasty was when I added some ground mild Italian sausage. I also increased the salt, garlic powder, and oregano to suite my taste. To replace the pasta I used spiraled zucchini.

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.
The taste of the sauce was good but it was wayyyyyyyy tooo watery. I wished I had cooked it down.
★★★
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
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?
★★★★★
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.

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.
★★★★★
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😊
★★★★★
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!
★★★★★
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. ❤️
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.

Just made. Will be made again- lovely
