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.
If your tomato sauce is too acidic and verging on bitter, turn to baking soda, not sugar. Yes, sugar might make the sauce taste better, but good old baking soda is an alkaline that will help balance the excess acid. A little pinch should do the trick.
Tomato sauce can be incorporated into a ketogenic diet but in very moderate amounts due to its high carbohydrate content. The key to using tomato sauce on a keto diet is strict portion control and balancing it out with other low-carb, high-fat foods.
Though botanically a fruit, raw tomatoes are considered keto-friendly, as they contain significantly fewer carbs than the same quantity of fruit. The same cannot be said of sundried tomatoes, as well as many other prepackaged tomato-based products, which are often sweetened with sugar.
Simmer 1 cup of shredded carrots or use sweet red pepper instead of green bell pepper. Sauté the vegetables in olive oil to express the sugars before adding them to the sauce. These vegetables will add a natural, mellower sweetness to your sauce than sugar or honey.
Most tomato sauce recipes are based on canned tomatoes, and canning companies carefully regulate the pH level of their products. So, the need to add sugar to tomato sauce is declining, but there may still be exceptions. It's best to make your sauce without sugar at first, then taste it and add a pinch if necessary.
"A pinch of sugar is a Southern Italian trick that was used when the sauce was made with end-of-season tomatoes that did not get ripe, or the tomatoes were so tart they needed to be balanced," Chiarello explained to Epicurious.
Even a small amount of baking soda significantly raises the pH of the sauce. While this reduces acidic taste, it also tamps down on the brightness that gives the tomato complexity.
Diluting a sweet tomato sauce will dull its sweetness, so you can add water or chicken or vegetable broth, a little at a time until the sauce tastes better. Or, if you like spicy food, you can try spicing the tomato sauce with some crushed chili flakes, which should help balance out its sweetness.
"They're low in carbs, so they fit perfectly into keto." One whole medium tomato contains roughly 5 grams of carbohydrates, of which 1.5 grams are fiber and 3 grams are sugar. If you're eating keto, your goal is to enter a state of ketosis (a fat-burning state kickstarted by reducing your protein and carb intake).
Keto practitioners incorporate a variety of different condiments into their diets, including hot sauce, low-carb BBQ sauce, sugar-free ketchup, mustard, ranch dressing, mayonnaise, guacamole, soy sauce, sour cream, and more.
Cream cheese: Cream cheese is very popular in the keto diet. At only 84 calories per 1 ounce serving, it has 1 gram of carbs and 2 grams of protein but packs 8 grams of fat per serving. It can be a keto-friendly snack or meal addition when more fat is needed.
Starchy vegetables contain more digestible carbohydrates than fiber and should be limited when you're on the ketogenic diet. These include corn, potatoes, sweet potatoes and beets. Limit high-sugar fruits too, which spike your blood sugar more quickly than berries and have more carbohydrates.
While cottage cheese is known for its high protein content, it also contains a relatively high amount of carbs and not that much fat, making it a less-than-ideal choice for keto. A ½-cup serving of cottage cheese contains 88 calories, 2.4 g of fat, 4.5 g of carbs, and 11.6 g of protein, per the USDA.
Olives are a great source of fat whilst remaining incredibly low in carbohydrates, in every 100g of olives there is only around 3 net carbs. They are the perfect way to fill yourself up whilst on a keto diet, either as a light snack or even on top of salads.
Rossetto Kasper recommends you try adding a small pinch of it to your sauce, stir it a few times, and taste. Repeat this process as needed until your sauce achieves a more balanced level of acidity.
Cinnamon, nutmeg, ginger, cloves, allspice, mace, cardamom and star anise are commonly associated with sweetness. These spices are often used in baked goods and pair especially well with fruit dishes. Vanilla extract can also make food seem sweeter, perhaps due to its aroma.
