1/4 cup fresh basil leaves, torn, plus more for garnish
-
2 sprigs fresh oregano (or 1 teaspoon dried oregano)
-
1 teaspoon fine sea salt, plus more to taste
-
1/2 teaspoon freshly ground black pepper
-
1 tablespoon tomato paste
-
1 cup (240ml) water (used to rinse tomato cans)
-
1 tablespoon unsalted butter (optional, for finishing richness)
Equipment

Large, heavy-bottomed pot or Dutch oven

Wooden spoon

Sharp chef’s knife and cutting board
-
Food mill, food processor, blender, or immersion blender (for desired texture)
Step-by-Step Instructions
Step 1: Build the Flavor Foundation (Soffritto)
(Time: 15-20 minutes | Intensity: Medium – requires attention)
-
Heat the olive oil in your large pot over medium heat until shimmering.
-
Add the diced onion, carrot, and celery (this trio is called a soffritto). Cook, stirring frequently with a wooden spoon, until the vegetables are very soft, translucent, and sweet, about 10-12 minutes. Do not let them brown.
-
Add the minced garlic and red pepper flakes (if using). Cook for just 60-90 seconds, until fragrant.
Step 2: Develop Depth & Add Tomatoes
(Time: 5 minutes | Intensity: Low)
-
Push the vegetables to the side of the pot. Add the tomato paste to the cleared spot and let it cook for 1 minute, stirring to “toast” it slightly. Then, mix it into the vegetables.
-
Carefully add the whole San Marzano tomatoes and their juices. Using clean hands or kitchen shears, gently crush the tomatoes in the pot—this rustic texture is key.
-
Pour 1 cup of water into each emptied tomato can, swirl to capture the remaining tomato goodness, and add this liquid to the pot.
-
Stir in the torn basil, oregano sprigs, salt, and pepper.
Step 3: The Slow Simmer (Where Magic Happens)
(Time: 1 to 1.5 hours | Intensity: Very Low – occasional stirring)
-
Bring the sauce to a lively simmer, then immediately reduce the heat to the lowest setting.
-
Partially cover the pot with a lid, leaving a small crack for steam to escape.
-
Let the sauce simmer gently, stirring every 15-20 minutes to prevent sticking. The sauce will gradually thicken, darken to a deep red, and the oil will shimmer on the surface. Taste and adjust salt halfway through. The longer it simmers (up to 2 hours), the richer it becomes.
Step 4: Finish & Finalize Texture
(Time: 10 minutes | Intensity: Low)
-
Remove and discard the oregano sprigs (if using fresh).
-
For a Smooth Sauce: Use an immersion blender directly in the pot to puree to your desired consistency. Alternatively, let the sauce cool slightly, then blend in batches in a standing blender (caution: hot liquids expand).
-
For a Rustic, Chunky Sauce: Use a food mill over a large bowl to remove seeds and skins, or simply leave it as-is.
-
Stir in the optional tablespoon of butter until melted. This adds a beautiful sheen and rounds out the acidity.
-
Taste one final time and adjust seasoning with salt and pepper.
Serving & Storing
-
Serve Immediately: Toss with 1-1.5 pounds of cooked pasta (reserving some pasta water to adjust consistency), top with fresh basil, grated Parmigiano-Reggiano, and a drizzle of extra-virgin olive oil.
-
Let It Rest (Pro-Tip): For even better flavor, let the sauce cool completely in the pot, then reheat gently to serve. This rest allows the flavors to fully harmonize.
-
Storage: Cool completely and store in an airtight container in the refrigerator for up to 1 week.
-
Freezing: This sauce freezes beautifully. Portion into freezer-safe jars or bags (leaving headspace) for up to 3 months. Thaw overnight in the refrigerator.
