Instructions

PIZZA SAUCE
Step 1
In a blender or food processor, purée tomatoes until mostly smooth.
Step 2
In a large skillet over medium heat, heat oil. Add garlic and cook, stirring, until fragrant, about 30 seconds. Stir in tomato paste and cook, stirring constantly, until darkened, 1 to 2 minutes. Add puréed tomatoes and 1 teaspoon salt. Bring to a boil over medium-high heat, then reduce heat to medium-low and simmer until sauce is thickened and reduced by about one-third, 20 to 25 minutes. Taste and season with salt and granulated sugar for sweetness, if needed. Let cool to room temperature.
Step 3
Make Ahead: Pizza sauce can be made 5 days ahead. Let cool completely, then store in an airtight container and refrigerate, or freeze up to 1 month.
