This recipe for sugar-free keto tomato sauce is full of flavor and can be used in so many recipes. All while only using 5 ingredients!
While tomatoes are keto-friendly, store-bought versions of tomato sauce can be full of hidden sugars, carbs and who knows what else that isn’t good for you.
This is a simple keto tomato sauce recipe that you can use in any way you like. Use this sauce on a cauliflower pizza crust, low-carb eggplant parmesan, or a keto pizza casserole.
The sauce can easily be prepared ahead, saving you time in the kitchen.
How to make keto tomato sauce
Step 1: In a small saucepan over medium-high heat, saute the garlic in the olive oil. Saute for a minute until the garlic is fragrant. Make sure the garlic doesn’t brown and become burnt.
Step 2: Turn the heat down and add the tomatoes, oregano, vinegar, and salt to the saucepan. Bring to a simmer and allow to cook for 30 – 40 minutes, allowing the sauce to reduce and thicken.
Step 3: Use the sauce immediately if desired or store for later use.
Make a batch and store it!
You can use this sugar-free tomato sauce immediately if desired or it can be stored for later use. To store the sauce, allow it to cool to room temperature first. Once cooled, transfer to an airtight container and refrigerate for up to 5 days.
You can also freeze the sauce after it has cooled to room temperature. Freeze in bags or a container for up to 6 weeks. Defrost before use.
Spicing it up!
Because this keto marinara sauce only uses 5 simple ingredients, it’s a great base that you can add other flavors to.
It tastes fantastic as it is, of course, but you can change the flavor profile by adding additional spices such as basil or parsley. You can also adjust the heat by adding red pepper flakes or even chopped chili peppers.
A sweet sugar-free tomato sauce?
The fact that this sauce is sugar-free doesn’t mean that it can’t be a little sweet! There are many no-carb sweeteners that you can eat on a keto diet.
I have made this sauce with a little bit of Stevia sweetener and it turned out great. Monkfruit sweetener is also a great option. Just be careful and add a little at a time as both sweeteners are quite strong.

Notes
You can use this tomato sauce immediately if desired or it can be stored for later use. To store the sauce, allow it to cool to room temperature first. Once cooled, transfer to an airtight container and refrigerate for up to 5 days.

Use a light hand, as a little baking soda goes a long way. For a batch of tomato sauce, start slowly with a mere 1/8 teaspoon. Give it a stir, taste, and see if you need more. You will notice the tartness start to fade, giving way to a sweetness.
For instance, many store-bought tomato products, such as tomato paste, tomato sauce, salsa, tomato juice, and even canned tomatoes, contain added sugars. This significantly raises their total carb content, making them more difficult to fit into a ketogenic diet.
A little sugar can make the rest of the flavors shine a little brighter, akin to adding vanilla to a chocolate cake. The goal is to amplify the natural sweetness of the tomatoes, not to turn the sauce sugary, so start with a pinch and work up if needed.
Add some lemon juice: The tartness of lemon can help cut through the sweetness. Squeeze in a little lemon juice and taste as you go until you achieve the desired balance. Vinegar: Balsamic vinegar or red wine vinegar can also work wonders in reducing sweetness.
If the reason you're wanting to “sweeten” the sauce is because the tomato is too tart [highly acidic] then a pinch of baking soda should do the trick. Or if you really like your sauce sweet for the sake of sweetness, then add a carrot or bit of sweet potato while it's cooking.
It is widely held that Italian immigrants began adding sugar to their sauce to make up for the overly acidic tomatoes they were forced to work with in their new home. But the history of sugar in pasta sauce actually goes back to Italy itself.
In this case, only 10 percent of your calorie intake should comes from carbs, leaving you to 20 to 30 grams of carbs per day to stay in that state. One tomato is barely a quarter of that limit, so there's little to stress about. Go ahead, have a tomato, or three.
Since most people following the diet are restricted to between 20 and 50 grams of net carbs per day, and the average ranch dressing is between 2 to 3 grams of net carbs per serving, it can be easily paired with a variety of healthy foods while on a ketogenic diet.
You can totally eat tomatoes while on a keto diet. In addition to being low carb, they're full of vital vitamins, nutrients, and healthy plant compounds. Just be sure to keep your carb count in check, since they aren't a zero-carb food. Constipation.
Approximately three dashes or ¼ teaspoon of nutmeg is plenty for a jar of tomato sauce. If you are making a large batch, add a bit more for good measure. While the flavor should be subtle, you still want it to make the other ingredients shine, so feel free to play around with the quantity until you get it just right.
The natural sugars in tomatoes themselves, such as fructose and glucose, contribute to the sauce's overall sweetness. Even in traditional home-made tomato sauce made from scratch, a little sugar is often added to balance the flavours.
Sweetener: Spaghetti sauce needs a bit of sugar of some sort to help balance the acidity of the tomatoes. You can sweeten the sauce with a bit of honey, or white or brown sugar. Seasoning: This recipe calls for dried parsley, oregano, basil, bay leaves, rosemary, garlic, salt, and pepper.
Great tomato flavor is all about balancing acidity and sweetness. Too much of either can leave you with asauce that tastes one-dimensional. Many sources recommend adding a pinch of baking soda to a sauce that's overly tart, which raises the pH and makes it less acidic.
Another method is to add about a 1/4 teaspoon of baking soda per quart. It won't add flavor as sugar will, but it will neutralize the acid. Don't overdo it as it will make the sauce taste salty.
"To reduce the sweetness, add vinegar or lemon juice, 1 teaspoon at a time, while heating the sauce," Richards notes. One way to tone down spiciness without adding sugar is to add coconut milk.
Think of cooking as simulating a ripening process - when you cook a fresh tomato it intensifies it and sweetens it. Canned tomatoes are already cooked so that process is halfway there. Fruit and carrots are a very natural way to add mild sweetness, and carrots are my personal favorite for this.
Many folks advise adding carrots to red sauce in order to add that sweetness. I tried grating carrots and cooking them down with the garlic right from the start. It certainly makes the sauce sweeter, but it also makes it taste like carrot soup.
Stir in sugar to make a very sweet sauce. If you prefer, you can use honey instead. Add the sugar 1 tsp. at a time, let the sauce simmer for two minutes and taste.
