Italian-style tomato sauce is a simple, classic seasoned tomato sauce commonly made in home kitchens. It combines smooth tomato purée with finely chopped onion, celery, and carrot, plus garlic and a pinch of red pepper flakes for depth. With a jar of this sauce and a box of pasta, spaghetti night is effortless.
This recipe has been reviewed for safety and accuracy by a Master Food Preserver certified through the University of Cornell Cooperative Extension.
The sauce emphasizes tomatoes with a modest amount of soffritto—onion, celery, and carrot—cooked until tender inside the purée. The vegetables remain as small flecks throughout the sauce, contributing texture and savory balance without overpowering the tomato flavor.
You can make the sauce from fresh paste tomatoes or use store-bought passata (strained tomato purée). Using passata shortens prep time because you only need to chop the vegetables.
This version is adapted from a tested home-preserving source and is written as an easy water bath canning recipe for pints or half-pints. It’s a reliable, straightforward sauce that stores well and performs the role of a basic red sauce for many dishes.
Notes from My Kitchen
I first learned variations of this simple sauce while living in Italy. Many home kitchens serve a plate of pasta with a sauce like this as a primo piatto before the rest of the meal. The version here captures that everyday, homestyle flavor—clean, tomato-forward, and comforting.

Fresh Tomatoes or Passata
This sauce starts with smooth tomato purée. Passata (strained purée) is convenient and widely available; choose plain passata without added oil or flavorings. If you prefer fresh, use paste/plum tomatoes—such as Roma or San Marzano varieties—because they yield thicker purée with less cooking time.
To make fresh purée: wash, core, and quarter the tomatoes, simmer briefly until soft, then pass them through a food mill to remove skins and seeds. Measure the purée by volume: the recipe is based on cups of purée.
Ingredients for Italian-Style Tomato Sauce
The ingredient list is short and purposeful: tomato purée, three soffritto vegetables, garlic, bottled lemon juice for acidity, and simple seasonings.
- Tomato purée or passata: Measure 8 cups of purée before cooking.
- Onion: 2/3 cup finely chopped.
- Celery: 2/3 cup finely chopped.
- Carrot: 1/2 cup peeled and finely chopped.
- Garlic: 2 cloves, finely chopped (or jarred minced garlic if preferred).
- Bottled lemon juice: 4 tablespoons. Use bottled lemon juice for consistent acidity required for safe water bath canning.
- Salt: 2 teaspoons, adjust to taste or skip if using salted passata.
- Black pepper: 1/2 teaspoon, freshly ground.
- Red pepper flakes: 1/2 teaspoon, optional for a gentle heat.
The measured vegetables, lemon juice, and purée are balanced for safe processing. Do not add additional vegetables or reduce the lemon juice for canned batches.
Notes on Safety and Variations
Bottled lemon juice provides the reliable acidity for water bath canning when low-acid vegetables are included. Adding more vegetables or changing their quantities alters the acidity balance and processing requirements—those changes require a different tested recipe and typically a pressure canner.
Salt and spices are for flavor and can be adjusted. Fresh herbs are best added when serving rather than before canning, since they lose brightness in processing.
How to Make Italian-Style Tomato Sauce
The method is straightforward: make or measure your purée, combine everything in a single pot, cook to reduce slightly, then fill hot jars and process.
Make the Tomato Purée
If using passata, skip to the cooking steps. For fresh tomatoes: wash, core, quarter, and simmer until soft. Run the softened tomatoes through a food mill to remove skins and seeds. Measure the resulting purée (8 cups) and reserve any extra for freezing or another batch.
Cook the Sauce
Place the measured purée or passata in a large stainless-steel or enameled pot. Add the finely chopped onion, celery, carrot, garlic, bottled lemon juice, salt, black pepper, and red pepper flakes.
Bring to a vigorous boil over medium-high heat, stirring frequently. Continue boiling hard, stirring often, until the sauce reduces by roughly one third and thickens slightly—about 15 minutes, though time varies with pot shape and heat. The vegetables should be tender but still visible as small pieces.
Canning Italian-Style Tomato Sauce
Prepare canner, jars, lids, and bands so they are hot and ready. Use a ladle and a funnel to fill jars, leaving 1/2 inch headspace. Remove air bubbles, recheck headspace, wipe rims, apply lids and bands fingertip-tight.
Process pints or half pints for 35 minutes in a boiling water bath with at least 1 inch of water over the jars. Adjust processing time for altitude (see notes). When processing ends, remove the canner lid, let the jars rest for 5 minutes, then lift them out and cool undisturbed for 12–24 hours before checking seals.
Altitude Adjustments
Increase processing time for higher altitudes:
- 0–1,000 ft: 35 minutes
- 1,001–3,000 ft: 40 minutes
- 3,001–6,000 ft: 45 minutes
- 6,001–8,000 ft: 50 minutes
- Above 8,000 ft: 55 minutes
Ways to Use Italian-Style Tomato Sauce
This sauce is versatile: toss it with spaghetti and finish with torn basil and grated parmesan, use it as a first-course pasta serving, or incorporate it into lasagna, baked ziti, chicken or eggplant parmesan, or meatball dishes. Reduce a bit further for a quick pizza sauce. Fresh herbs and a drizzle of olive oil added when serving brighten the flavor.
Storage and Shelf Life
After cooling, test each lid by pressing the center—sealed lids should not flex. Remove bands and label jars with the date. Sealed jars keep best for about 12–18 months in a cool, dark place. Unsealed jars should be refrigerated and used within a week, or reprocessed within 24 hours with new lids. After opening, refrigerate and use within 1–2 weeks.
Yield Notes
Plan on roughly 8 cups of purée for this recipe, which yields about 3 pints. If using fresh tomatoes, expect to start with several extra pounds since milling and pulp loss reduce the final volume. With passata, measure 8 cups directly.
Italian-Style Tomato Sauce FAQs
Can I use store-bought passata? Yes. Plain passata replaces fresh purée cup for cup. Avoid passata with added oil or flavorings and keep the full amount of bottled lemon juice.
Can I omit the lemon juice? No. Bottled lemon juice provides consistent acidity required for safe water bath canning when low-acid vegetables are included. If the sauce tastes tart, add a small pinch of sugar when serving.
Can I add more vegetables? No for canning: adding vegetables or increasing their quantities changes the tested acidity balance. For a more vegetable-heavy sauce, use a recipe designed for pressure canning.
Can I use quart jars? This recipe is tested for pints and half pints only. Do not use quarts unless you follow a tested process for that jar size.
Can I add herbs? Dried herbs can be added before canning as seasoning. Fresh herbs are best stirred in when you open the jar to preserve color and flavor.
