Keto Tomato Sauce: 10 Recipes to Please Your Taste Buds

If you’ve been on a ketogenic diet for a long time, you may get bored with the monotony of your nutrition. Sometimes you can get tired of even the tastiest meat or bacon if you don’t add variety to your meal plan. In such cases, I prepare different keto sauces.

Tomatoes are questionable for keto lovers. Since they contain some carbs, they need to be balanced with healthy fats in order for the sauce to remain high in fat and low in carbs. You can safely eat tomatoes if you have already adapted and your ketosis is stable. But if you are just at the beginning of your keto journey, you should limit the amount of sauce to two tablespoons per meal.

Let’s take a look at 10 of my favorite keto tomato sauce recipes that will perfectly complement any dish.

Spicy Tomato Salsa

Fresh homemade salsa can be your favorite keto sauce. It’s so easy to make and can save any keto food, be it fish, chicken, beef, or salad.

The combination of fresh garlic, red tomatoes, onions, jalapenos, and cilantro is the perfect flavor enhancer and is 100% keto-friendly. Try it yourself!

Is Garlic Keto? Carbs, Calories and Tips

Oregano, shallots, cumin, red onion, lime juice, and chili are some of the great keto-friendly salsa ingredients you can use to get a fresh taste.


  • 400 g canned tomatoes
  • 300 g fresh tomatoes
  • 100 g butter
  • 2 cloves of garlic
  • 5 g thyme (fresh or dried)
  • 20 g basil
  • сhili pepper to taste
  • 50 ml olive oil
  • salt pepper
  • stevia


Peel the tomatoes – cut slightly, dip in boiling water, and then ice water.

Pour half of the olive oil into the pan, and add peeled garlic cloves, a sprig of thyme, and a little basil to flavor the oil. Place a pan over medium heat and saute until strong garlic and thyme aroma appears.

Remove the garlic, add the tomatoes and chili, and simmer for a couple of minutes. Next, add canned tomatoes and taste them. Everything depends on the tomatoes – add a little keto sweetener to balance the taste, or perhaps a little balsamic vinegar if you need to emphasize the sourness.

Add butter, and the remaining basil to the tomatoes, turn off the heat, and let it brew for an hour. Remove the thyme and basil from the mix. Whisk the sauce in a blender until it turns red. Add the remaining olive oil, and the color should turn orange. Salt to taste. Enjoy!

Keto BBQ Sauce

It is the perfect addition to summer BBQ or keto pizza. When you don’t know which sauce to choose in the store, you need to make your own. The keto sauce in this recipe is suitable for grilled and smoked meats, especially ribs, pork, and fried chicken.


  • 1 tsp mustard
  • 1 tsp cumin
  • 2 tbsp olive oil
  • 3/4 cup water
  • Sweetener to taste

Add olive oil to a small saucepan and heat over medium heat. Add shallots and salt and sauté until soft and clear, about 4 minutes. Then add the minced garlic and fry for another 1 minute.

Add tomatoes, vinegar, sweetener, barbecue flavor, spices, and water. Stir and heat until the ingredients come together, more or less evenly. Then reduce heat to low and simmer for 20 minutes, frequently stirring, until the sauce thickens and darkens.

Let the sauce cool slightly, then place in a blender and beat until smooth. Add salt if necessary.

Keto Chili Sauce

This sauce contains a sweetener, which to some extent removes the spiciness. As an alternative to raw peppers, use a tablespoon of chili flakes. For a softer sauce, you can remove all the seeds and skin.

Is Chili Keto? The Best Low-Carb Recipe

This keto sauce can be stored in the fridge for up to 1 month. It can be used to make marinades, as an additive to meat and vegetable dishes, and for dipping keto tortillas or chips.


  • 10 g of fresh ginger
  • 1 tomato
  • 10 grams of red chili (or 1 tablespoon of chili flakes)
  • A pinch of salt
  • 1 tbsp erythritol
  • 1 tbsp apple cider vinegar


In a blender bowl, combine all the sauce ingredients.

Transfer the mixture to a saucepan, heat to a simmer, cover, and simmer for 15-20 minutes until the sauce thickens. Stir the sauce occasionally with a wooden spoon.

Put it into a jar, close the lid and cool at room temperature.

Classic Keto Ketchup


  • 150 g canned tomatoes
  • 100 ml of water
  • 1 tsp sweetener
  • 2 tsp salt
  • 1 tablespoon apple cider vinegar
  • Seasonings to taste.


Place the canned tomatoes in a small saucepan. Add water. Stir and put on low heat. Then add one teaspoon of sweetener. Continue stirring while boiling. Add one tablespoon of apple cider vinegar and salt.

In a separate bowl, combine the seasonings. I like 1/4 teaspoon of paprika, oregano, and dry garlic. Add seasoning to ketchup, cover, and simmer for another 20 minutes. Cool it, and enjoy!

Keto Marinara

This sauce can be used for keto pizza, mozzarella sticks, meat dishes, and baked vegetables.


  • 2 tsp olive oil
  • 3 minced garlic cloves
  • 2 tsp onion flakes
  • 600 gr canned tomatoes
  • 2 tsp chopped thyme
  • 2 tsp chopped oregano
  • 1 tsp red wine vinegar
  • 2 tbsp sweetener
  • pinch of salt
  • 1 tsp ground black pepper
  • 2 tsp finely chopped parsley


Place the oil, thyme, garlic, onion flakes, and oregano in a saucepan or deep skillet. Fry over medium heat for 3 minutes until a strong spice aroma appears.

Add the canned tomatoes and stir well. Add sweetener, pepper, salt, and red wine vinegar and bring to a boil.

Turn off heat and add finely chopped parsley. Cool the sauce and transfer to the jar.

Keto Bolognese Sauce

Although the traditional Bolognese recipe contains ground beef, a mixture of pork and ground beef can be used for the keto diet. The extra fat makes the sauce juicier and increases the fat percentage of the finished meal, which is good for the keto diet.

This sauce can also be made from a mixture of other types of minced meat: pork, veal, and beef.

Besides veggie pasta, the sauce can be served with cauliflower rice or baked vegetables.

The sauce can be stored in the refrigerator for up to 5 days and in the freezer for up to 1 month.


  • 2 tbsp olive oil
  • 450 g minced beef
  • 800 g chopped peeled tomatoes
  • 2 tbsp canned tomatoes
  • ½ cup chopped onions
  • 2 tsp garlic powder
  • 1 tsp oregano
  • 2 tsp basil
  • 2 tsp sweetener
  • 12 tsp salt
  • 90 g dry red wine (optional)
  • ¼ tsp red pepper flakes (optional)


Heat the olive oil in a skillet or saucepan. Add minced meat and heat for 5 minutes, stirring with a wooden spoon to avoid pieces in the finished sauce. Add onion, salt, garlic, oregano, basil, red pepper, sweetener, and canned and fresh tomatoes to the minced meat, and stir. Cover and simmer for 10 minutes. Then use a wooden spoon to mash the large pieces of the tomato until they release the juice and break into smaller pieces.

Simmer for another 20-25 minutes without a lid over medium heat until the sauce thickens and the tomatoes are cooked and tender, stirring occasionally. The longer meat and tomatoes are cooked together, the richer and tastier the sauce will be.

The sauce is served hot with grated cheese and vegetable pasta.

Spicy Tomato Sauce with Herbs

I love this sauce for its quick preparation and versatility. Most often, I add it to my morning scrambled eggs. It makes them magical.


  • 100 g of canned tomatoes
  • 2 tbs Italian seasoning
  • pinch of salt
  • sweetener to taste
  • 50 ml of water
  • 1 tsp of apple cider vinegar


Mix all ingredients and beat in a blender. Pour water in a little bit and adjust the density of the sauce to taste. You can add cilantro, basil, fried mushrooms, and garlic, and you get a completely different taste.

Finely chop a large onion, mince the garlic, and fry in olive oil until the onion is golden.

Add canned tomatoes and dilute with water to a ketchup consistency.

Add salt to taste, sweetener, basil, and oregano. The amount of all ingredients can be varied according to taste, but it is better to add more basil and twice as less oregano. Simmer covered for 10 minutes, chill and enjoy.


The sauce turns any food into a healthy pleasure if it is of high quality, natural, and does not contain dangerous ingredients. And this is often a problem because most sauces sold in stores contain synthetic colors, starch, and sugar, flavor enhancers. They often use cheap vegetable oils with unhealthy omega-6 fatty acids and trans fats. So prepare your keto sauces and enjoy healthy keto food!
