Ingredients
Method
Step-by-Step
- Warm the olive oil in a heavy saucepan over medium heat. Add the diced onion and cook for 5–7 minutes, stirring occasionally, until soft but not browned.
- Add the minced garlic, dried oregano, and red-pepper flakes if using. Cook for 30–60 seconds, just until fragrant, taking care not to darken the garlic.
- Add the tomatoes, kosher salt, and black pepper. Crush whole tomatoes with a spoon or potato masher, then bring the mixture to a gentle simmer.
- Reduce the heat to low and simmer uncovered for 30–45 minutes, stirring occasionally. Add a little water if the sauce becomes too thick before the tomatoes have mellowed.
- Stir in the basil during the final 5 minutes, or add fresh basil after removing the sauce from the heat. Taste and adjust the salt, adding sugar only if the tomatoes taste notably acidic.
Notes
For a smooth sauce, blend briefly with an immersion blender after simmering. For pasta, reserve some cooking water and stir a few tablespoons into the sauce while tossing. Refrigerate leftovers in a covered container for up to 4 days or freeze in portions for longer storage.
