This San Marzano tomato sauce is quick, simple, and versatile—perfect for pizza, pasta, or any Italian dish. Made with canned San Marzano tomatoes, it uses just a few pantry ingredients and is ready in about 20 minutes.
I make this San Marzano tomato sauce all the time. It works beautifully for classic Italian recipes and everyday meals, and using canned tomatoes keeps it fast without sacrificing flavor. You’d never guess it started in a can.
This is an authentic, no-fuss Italian sauce: many cooks in Italy rely on high-quality canned tomatoes rather than peeling and crushing fresh ones at home. The right canned tomatoes give you bright, balanced flavor without added sugar or long simmering.
Because the tomatoes are already cooked during canning, this sauce doesn’t require hours on the stove. In under 30 minutes you’ll have a smooth, flavorful tomato sauce suitable for dishes such as classic pasta or a quick homemade pizza.
San Marzano sauce ingredients
This flavorful sauce comes together with simple pantry staples:
- Canned whole San Marzano tomatoes: Choose genuine San Marzano tomatoes for their natural sweetness, thicker walls, and low acidity. They make an exceptional sauce without added sugar. If possible, buy whole tomatoes and crush them by hand for the best texture.
- Olive oil: Use a good-quality olive oil to give the sauce a silky mouthfeel.
- Garlic: Add to taste—minced, thinly sliced, or grated.
- Kosher salt: Balances and enhances the tomato flavor.
- Crushed red pepper flakes (optional): For a touch of heat, adjust to your preference.
What are San Marzano tomatoes?
San Marzano tomatoes are grown in the volcanic soils of the Sarnese Nocerino area in Campania, Italy. They are vine-ripened and prized for a sweeter, less acidic flavor, thicker flesh, fewer seeds, and lower water content than many other plum tomatoes. Those qualities make San Marzano tomatoes especially well-suited for sauces—no sugar required.
When shopping, look for true San Marzano labels (D.O.P. or other certification) to ensure they were grown and packaged according to regional standards. Avoid “San Marzano-style” labels if you want the authentic product.
How to make San Marzano tomato sauce
This recipe is adapted from classic Italian methods and is intentionally simple.
Step 1: Crush the tomatoes by hand
Pour the canned San Marzano tomatoes into a large bowl and gently crush them with your hands to the texture you prefer. Remove any tough stem pieces. Pour about a quarter of the empty can’s water into the bowl, swirl to collect any remaining tomato, and set aside.
Step 2: Sweat the garlic and pepper flakes in olive oil
Heat a large, deep skillet over medium heat. Add the olive oil and, once it shimmers, add the garlic and crushed red pepper. Stir for one to two minutes until fragrant—be careful not to brown the garlic.
Step 3: Add the tomatoes and simmer until done
Increase the heat to medium-high, add the crushed tomatoes and the reserved can water to the pan, and bring to a brisk simmer. Once bubbling, reduce to medium and cook, stirring frequently with a wooden spoon, until the sauce is smooth and slightly thickened—about 20 minutes.
Expert tips
- Maintain a steady medium simmer. Too low and the tomatoes won’t break down; too high and the sauce will over-reduce into something more like paste.
- Use whole canned tomatoes and crush them yourself for the best texture. Crushed tomatoes work if that’s what you have on hand.
- Cook in an enamel or stainless-steel pan to avoid any metallic taste—acidic tomato sauce can react with some cookware.
- A wooden spoon is ideal for stirring and breaking down tomatoes gently as the sauce cooks.
Recipe variations
This base sauce is a canvas—try these simple variations:
- Add a splash of red or white wine while simmering for extra depth.
- Finish with fresh herbs like basil or parsley for brightness.
- Stir in dried oregano or an Italian herb blend during the simmer for a classic profile.
- For a creamy version, add a little cream to make a pink sauce.
- Simmer with a piece of Parmesan rind to boost savory, umami notes.
What to make with San Marzano tomato sauce
This sauce is extremely versatile. Use it on pizza, toss with pasta, spoon over vegetables, or use as the base for braises and soups. It’s also a great starting point for meat sauces like a ragu when you want to add proteins and longer cooking time.
- Zucchini Parmesan layered with this sauce makes a hearty, gluten-free casserole.
- Traditional stuffed cabbage or hearty bean-and-sausage dishes benefit from this bright tomato base.
- Use leftovers to dress roasted vegetables, braised greens, or as a quick dipping sauce.
FAQ
In many Italian recipes, garlic and onion are not used together; using one or the other keeps the flavor focused. Also, diced onions can interrupt the smooth texture of this sauce. If you prefer onions, add them finely minced and sauté until soft before adding the tomatoes.
Canned tomatoes are already cooked and concentrated during processing, so they don’t need long simmering to develop flavor. Extended cooking can actually diminish brightness unless you’re building a meat-based ragu that needs time for the proteins to tenderize and meld with the sauce.
Storage & Freezing
- To store: Keep the sauce in an airtight container in the refrigerator for up to 4 days.
- To freeze: Transfer into freezer-safe containers or portion into smaller containers and freeze for up to 3 months. Thaw in the refrigerator before reheating.

Recipe
San Marzano Tomato Sauce
Ingredients
- 28 oz San Marzano tomatoes
- ¼ cup olive oil
- 1 teaspoon kosher salt
- 2 cloves garlic minced, sliced, or grated
- pinch crushed red pepper
Instructions
-
Pour the can of San Marzano tomatoes into a large bowl and crush them by hand. Remove any tough stem pieces. Add about ¼ can of water to the tomatoes and set aside.
-
Heat a large, deep skillet over medium heat. Add olive oil, then garlic and crushed red pepper. Stir for 1–2 minutes until fragrant, taking care not to brown the garlic.
-
Raise heat to medium-high, add the crushed tomatoes and reserved can water to the pan, and bring to a strong simmer. Reduce to medium and cook, stirring frequently, for about 20 minutes until smooth and slightly reduced.
Notes
- A wooden spoon helps break the tomatoes down naturally; a silicone spatula works if needed.
- Keep a medium simmer: too low and the sauce takes longer to smooth; too high and it reduces too much.
- Prefer enamel or stainless cookware for tomato sauces to avoid metallic flavors; avoid using unseasoned cast iron for acidic sauces.
- Whole canned tomatoes crushed by hand give the best texture; crushed canned tomatoes are an acceptable shortcut.
