You'll say goodbye to store-bought marinara forever after you try this keto marinara sauce! It's super fast and easy to make, loaded with flavor, healthy, and cost-effective. Plus, it's also dairy-free, vegan, paleo, and whole30-compliant!
While store-bought marinara sauce is convenient, it's usually loaded with sugar, soybean oil, fillers, and other undesirable ingredients.
And if you do find a good marinara sauce with high-quality ingredients and no added sugar, it's crazy expensive!
But I'm here to tell you that making your own is super easy and cost-effective.
It's perfect to whip up and put on top of flatbread, zucchini noodles, or used to make some killer stuffed peppers!
🍅 The tomatoes
The taste of this keto marinara largely depends on the tomatoes you use. So be sure to use some that are of high quality!
I prefer to use San Marzano tomatoes (the brand doesn't matter) because they have such a great taste, however, you can use any tomatoes you prefer.
💭 Frequently asked questions
Although tomatoes are naturally a bit high in carbs, marinara can be keto-friendly if eaten in moderation and there is no added sugar.
Many store-bought marinara sauces have added sugar and soybean oil - making them not paleo or whole30-compliant. So you need to read the labels carefully. Or you can make your own homemade marinara which is super easy and cheaper than the store-bought variety.
Allow the sauce to cool, then blend in either a food processor or blender. After it's smooth, it can be returned to the pan and reheated.
It can be stored in an airtight container in the fridge up to 4 days or frozen up to 6 months.
No, you can use also use 28 oz. of diced tomatoes or crushed tomatoes. If you use diced tomatoes, they are harder to crush so you'll probably need to blend them. And crushed tomatoes are a bit higher in carbs, which is why I chose not to use them.
🔪 Easy instructions
Heat some oil over medium heat. Once hot, add a chopped onion and cook for 3 to 5 minutes, or until the onion is transluscent.
Get some beef broth ready to go (you don't want the garlic to burn!), then add 4 cloves of garlic.
Cook for around 30 seconds, or until fragrant, then add the broth. Allow to bubble for 2 to 3 minutes.
Stir in a 28-oz can of whole peeled tomatoes, parsley, oregano, and sea salt. Use a wooden spoon or potato masher to crush the tomatoes.
Bring to a simmer and simmer, uncovered, 15 to 20 minutes, or until thickened.
Add some red wine vinegar, then taste and adjust salt and seasonings as needed.
And please don't skip the red wine vinegar! It adds a depth of flavor that you don't want to miss 😀
If you prefer a little sweetness to your sauce, feel free to add 1 tablespoon of Keto Sweetener.
For a smooth sauce, blend with an immersion blender.
If you don't have an immersion blender: Allow to slightly cool, then process in a food processor or blend in a stand blender.
Garnish with basil and serve!

Brenda says
I just made this and it is absolutely delicious! I did go with the vegan option and made it with vegetable broth. I couldn’t find the brand of tomatoes recommended, but did find another brand of whole Italian tomatoes (no salt added) at sprouts farmers market. I didn’t have oregano on hand and added some basil flakes instead. I chopped up the onions in a processor and left the sauce fairly chunky, but used at my immersion blender on it just a bit. The sauce looks just as fabulous as it tastes and I could eat it by the spoonful all by itself! I do not miss all that added salt at all! Definitely a thumbs up!
Cassidy Stauffer says

XO,

This recipe is labeled as vegan, but one of the ingredients is beef broth. I'm going to try it with veggie broth and hope for the best. I just didn't want you to get clobbered by an angry vegan.
Cassidy Stauffer says
Oh no, I forgot to add the vegan option!!! Thank you SO much for pointing this out to me, I'll fix it right away!!!
