Ingredients

• 2 tablespoons extra virgin olive oil
• 1 small onion or shallot, chopped
• 3 garlic cloves, peeled and smashed
• 1 can (28 ounces) San Marzano tomatoes
• Sea salt and freshly ground pepper
• teaspoon red pepper flakes (or to taste)
• 1 to 2 tablespoons sugar (optional)

Instructions

1. In a large saucepan, heat the oil over medium-high heat. Add the onion and garlic, reduce the heat to medium, and cook, stirring occasionally, until the onion is tender and translucent and the garlic is very aromatic, 6 minutes.
2. Add the tomatoes (and their juices) and continue to cook, using a wooden spoon to gently break up the tomatoes. Season well with salt and pepper and add the pepper flakes. Cook for 12 to 15 minutes for the sauce to thicken a bit and so the flavors begin to meld. Taste and decide if you need to add more salt to bring out the flavor of the tomatoes or even a bit of sugar (this depends on the tomatoes and varies with every can).
3. Use an immersion blender (or a food processor or standing blender) to puree the tomato sauce. Taste again and season if needed.
