Introduction
This classic Italian red sauce made with San Marzano tomatoes is rich, flavorful, and perfect for pasta, pizza, or any dish that calls for a vibrant tomato sauce. It balances acidity with a touch of sweetness and a gentle kick of spice, making it a versatile staple in your kitchen.

Ingredients
- 1 28 oz can whole, peeled Italian tomatoes
- 2 Tbsp olive oil
- 1 medium onion, chopped (about 1/2 cup)
- 2 cloves garlic, minced
- 1/2 cup red wine (optional)
- 3 oz tomato paste (or 1/2 of a 6 oz can)
- 2 tsp kosher salt (to start)
- 1 tsp ground black pepper
- 1 Tbsp sugar
- Crushed red pepper (to taste, start with 1/4 tsp if you like heat)
- Water (as needed, in 1/4 cup increments)
- Fresh basil (optional)
Instructions
- Step 1: Place the whole tomatoes with their juices into a blender and pulse until you reach your desired sauce consistency.
- Step 2: Heat olive oil in a 4-quart saucepan over medium heat. Add the chopped onion and sauté until translucent and golden, about 5 minutes. Add the minced garlic and cook for 30 seconds until fragrant.
- Step 3: If using, pour in the red wine and cook for at least 2 minutes, allowing the alcohol to evaporate and the flavors to meld.
- Step 4: Lower the heat to medium-low and add the tomato paste. Stir and swirl it around with the onions until softened, about 2 minutes. Add the salt, black pepper, crushed red pepper, and sugar. Stir quickly to combine, letting the sugar caramelize slightly without burning.
- Step 5: Immediately add the pureed tomatoes to the pan. Simmer gently over low heat for about 45 minutes, stirring occasionally. After 30 minutes, taste and adjust seasoning by adding more salt, pepper, or sugar if needed.
- Step 6: Continue simmering until the sauce thickens to a rich, vibrant red with deep flavor. Add water in small increments if the sauce becomes too thick.
- Step 7: If you like, stir in fresh basil just before serving for a bright, herbal note. Use the sauce immediately or as a base for meat dishes or pizza.
Tips & Variations
- For a smoother sauce, blend the tomatoes longer or pass the sauce through a sieve after cooking.
- Add finely grated carrot at the onion stage for natural sweetness instead of sugar.
- Use dry white wine instead of red for a lighter flavor profile.
- Leave out the wine for a non-alcoholic version; just increase the cooking time slightly to develop flavor.
- For extra depth, add a splash of balsamic vinegar or a pinch of dried oregano.
Storage
Store the cooled red sauce in an airtight container in the refrigerator for up to 5 days. To freeze, place in freezer-safe containers and keep for up to 3 months. Reheat gently on the stove over low heat, adding a splash of water if the sauce has thickened too much.

FAQs
Can I use regular canned tomatoes instead of San Marzano?
Yes, regular canned whole peeled tomatoes will work, but San Marzano tomatoes are preferred for their sweeter, less acidic flavor which enhances the sauce.
Is the red wine necessary?
The red wine adds depth and richness but is optional. If you omit it, simply simmer the sauce a bit longer to let the flavors develop fully.

Ingredients
Main Ingredients
- 1 28 oz can whole, peeled Italian San Marzano tomatoes
- 2 Tbsp olive oil
- 1 medium onion, chopped (about 1/2 cup)
- 2 cloves garlic, minced
- 1/2 cup red wine (optional)
- 3 oz tomato paste (or 1/2 of a 6 oz can)
- 2 tsp kosher salt (to start)
- 1 tsp ground black pepper
- 1 Tbsp sugar
- Crushed red pepper, to taste (start with 1/4 teaspoon if you like heat)
- Water, as needed (in 1/4 cup increments)
- Fresh basil (optional, for garnish or added flavor)
Instructions
- Puree the Tomatoes. Place the whole peeled tomatoes along with their juices into a blender and pulse until the sauce reaches your desired consistency, whether chunky or smooth.
- Sauté Onions and Garlic. Heat olive oil in a 4-quart saucepan over medium heat. Add the chopped onions and sauté until they become translucent and develop a rich color, about 5 minutes. Add minced garlic and cook briefly for 30 seconds until fragrant.
- Add Red Wine. Pour in red wine if using. Cook for at least 2 minutes, allowing the wine to reduce slightly and incorporate with the onion and garlic mixture.
- Incorporate Tomato Paste and Spices. Reduce heat to medium-low, add tomato paste, and stir to combine with onions until softened, about 2 minutes. Add kosher salt, black pepper, sugar, and crushed red pepper. Quickly combine to let the sugar caramelize lightly without burning.
- Add Pureed Tomatoes and Simmer. Pour the pureed tomatoes into the saucepan and stir. Simmer the sauce gently over low heat for about 45 minutes, stirring occasionally. Check seasoning around 30 minutes and adjust salt, pepper, or sugar as needed to balance acidity.
- Final Taste and Adjust. Taste the sauce and make final seasoning adjustments to achieve a rich, balanced, and flavorful sauce.
- Serve or Store. Once thickened to your liking, use the sauce immediately with pasta, meat, or pizza, or cool and store for later use.
Notes
- Red wine is optional but adds depth to the sauce; substitute with water or broth if preferred.
- Use crushed red pepper sparingly to control heat levels.
- Simmering at low heat helps develop richer flavors and a thicker texture.
- Adjust sugar cautiously to balance tomato acidity without making the sauce overly sweet.
- Fresh basil can be added at the end of cooking or as a garnish for additional aroma and flavor.
