Ingredients

• 3 tablespoons Olive oil
• 3 large Garlic cloves, minced
• 1 medium Yellow onion, finely chopped
• 800 grams Tomatoes (fresh or canned, peeled and diced)
• 2 tablespoons Tomato paste (unsweetened)
• 1 teaspoon Dried oregano
• 1 teaspoon Dried basil
• 0.5 teaspoon Paprika powder
• 0.5 teaspoon Ground black pepper
• 0.75 teaspoon Sea salt
• 1 teaspoon Erythritol (optional, for balancing acidity)
• 5 leaves Fresh basil leaves (optional, for garnish)

Directions

Step 1

Heat the olive oil in a medium-sized saucepan over medium heat.

Step 2

Add the minced garlic and chopped onion to the pan. Sauté until fragrant and the onion becomes translucent, about 3–4 minutes.

Step 3

Add the diced tomatoes and tomato paste to the pan. Stir to combine.

Step 4

Season the mixture with dried oregano, dried basil, paprika powder, ground black pepper, and sea salt. Stir well to incorporate the spices.

Step 5

Bring the sauce to a simmer over medium heat, then reduce the heat to low. Cover the saucepan with a lid, leaving a small gap for steam to escape.

Step 6

Allow the sauce to simmer gently for 35–40 minutes, stirring occasionally. The sauce should thicken and the flavors should meld beautifully.

Step 7

Taste the sauce and, if needed, add the erythritol to balance the acidity of the tomatoes.

Step 8

For a smooth texture, use an immersion blender to puree the sauce directly in the pan, or transfer it to a blender to puree in batches (optional step).

Step 9

Serve warm over your favorite keto dish, and garnish with fresh basil leaves if desired.

Step 10

Store leftovers in an airtight container in the refrigerator for up to 5 days or freeze for up to 3 months.
