San Marzano Tomato Sauce (Rich & Simple)

This homemade San Marzano tomato sauce is rich, garlicky, and naturally sweet without added sugar. It simmers into a thick, versatile red sauce for pasta, pizza, lasagna, meatballs, or dipping warm focaccia.

This San Marzano tomato sauce is my go-to homemade red sauce when I want something richer than a quick marinara but still easy enough for a weeknight. It uses whole peeled San Marzano tomatoes, lots of garlic, olive oil, basil, and oregano, then simmers for 45 minutes so the tomatoes break down into a thick, balanced sauce without needing sugar.

I like to pulse the tomatoes first so the sauce has body but still keeps a little texture, then add fresh basil at the end so it tastes bright instead of muted. Use it for pasta, pizza, lasagna, meatballs, or anywhere you'd normally use a jarred marinara.

⭐️ Why This San Marzano Marinara Sauce Works

• Rich flavor without a long simmer: A 45-minute simmer gives the sauce more depth than ultra-quick versions, without turning it into an all-day project.
• No added sugar: San Marzano tomatoes are naturally sweet and balanced, so the sauce doesn't need sugar.
• Thick, versatile texture: Pulsing the whole peeled tomatoes gives the sauce body while still leaving some rustic texture.
• Simple pantry ingredients: Tomatoes, olive oil, garlic, herbs, salt, and pepper keep the flavor clean and tomato-forward.
• Freezer-friendly: Make a batch once and use it for pasta, pizza, lasagna, meatballs, or dipping focaccia.

🤔 What makes San Marzano Tomatoes Different?

• They are a plum tomato prized for sweetness, low acidity, thick flesh, and fewer seeds.
• Authentic D.O.P. San Marzano tomatoes are grown in a specific region near Mount Vesuvius.
• For the best sauce, buy whole peeled tomatoes, not pre-crushed, when possible.
• "San Marzano-style" is not the same as D.O.P.

🍅 Ingredient Notes

• San Marzano whole peeled tomatoes - Use whole peeled tomatoes for the best texture and flavor. Look for the D.O.P. seal if you want authentic Italian San Marzano tomatoes; "San Marzano-style" is not the same thing.
• Extra-virgin olive oil - Use a good-quality brand of olive oil since only a few ingredients are used in this recipe.
• Garlic - Eight cloves give the sauce bold flavor. Cook it gently so it turns fragrant but doesn't brown or taste bitter.
• Fresh basil - Add it at the end so the flavor stays bright. Fresh basil works best, but 1 tsp. of dried basil will work.
• Dried oregano - Adds a savory, classic Italian sauce flavor without overpowering the tomatoes.
• Red pepper flakes - Optional, but helpful for a nice pop of heat.

📝 Variations & Substitutions

• Make it in a slow cooker: To do this, saute garlic in a pan for 1 minute first, then add all of the ingredients into your slow cooker, and cook on low for 6-7 hours.
• Add a Parmesan rind. Don't throw away that Parmesan rind! Add it to your simmering sauce for deeper flavor (you can also add it to soups and stews for more complex flavor).

🥄 How to Make San Marzano Tomato Sauce

Carefully pour the San Marzano tomatoes (and juices) into the bowl of a food processor. Pulse to desired consistency (I like to leave my tomatoes a bit chunky since they fall apart even more as they cook). Set aside. **If you don't have a food processor, you can use your hands to rip up the tomatoes when you add them to the pan.

Pour olive oil into a large skillet over medium-low heat and let it warm to a shimmer, about 1-2 minutes. Add garlic and cook for 1 minute.

Add the chopped tomatoes, dried herbs (*if using fresh basil, wait and add it at the very end), salt, and pepper, and stir to combine. Adjust the heat to low, cover, and simmer for 45 minutes, stirring frequently.

When your sauce is done simmering, add fresh basil and red pepper flakes, if using, and season to taste with additional salt and pepper. Serve with your favorite Italian dishes.

👩🏼‍🍳 Expert Tips

• Use whole peeled tomatoes. They're usually better quality than pre-crushed tomatoes and let you control the final texture.
• Don't brown the garlic. Cook it just until fragrant; browned garlic can make a simple tomato sauce taste bitter.
• Add fresh basil at the end. This keeps the flavor bright instead of muted.
• Simmer uncovered if the sauce is too thin. If it looks watery after 45 minutes, remove the lid and let it reduce for a few more minutes. Alternatively, learn my tricks on how to thicken tomato sauce.
• Taste before serving. Tomatoes vary by brand, so adjust the salt, pepper, and red pepper flakes at the end.
• Leave the sauce slightly chunky. The tomatoes continue to break down as they simmer.

🍽 Ways To Use No Sugar Tomato Sauce

This homemade marinara sauce is thick, rich, and versatile enough to use anywhere you'd normally use marinara or jarred pasta sauce. Toss it with your favorite pasta, spoon it over vegetarian meatballs, layer it into veggie lasagna, or use it as a simple vegetarian pizza sauce.

It's also great as a dipping sauce for garlic bread, homemade focaccia, mozzarella sticks, or roasted vegetables. I like to keep a batch in the freezer for quick weeknight dinners, especially when I need an easy sauce for pasta bakes, flatbreads, or stuffed shells.

Storage, Freezing, & Reheating

• Storage: Once your sauce has cooled, transfer it to an airtight container and store in the refrigerator for up to 7 days.
• How to freeze: This sauce freezes really well! Make sure your sauce is cooled completely, then pour it into quart-sized freezer bags. Freeze for up to 3 months. To thaw, place it in the fridge overnight.
• To reheat, pour marinara sauce into a skillet over medium-low heat for 10 minutes, stirring frequently, until heated through.
