Step 1

Pulse tomatoes with juices in a blender to form a coarse purée. Heat oil in a medium saucepan over medium heat. Add garlic and cook, stirring often, until beginning to brown, about 2 minutes. Add tomato purée and sugar and season with salt. Bring to a boil, reduce heat, and simmer gently until sauce is slightly thickened, 10-15 minutes.

Step 2

DO AHEAD: Sauce can be made 3 days ahead. Cover and chill, or freeze for up to 3 months.
