Ingredients for Raos Red Sauce
Ten simple ingredients create this rich, velvety Italian sauce with authentic flavor.
| Ingredient | Amount | Notes |
|---|---|---|
| San Marzano Whole Peeled Tomatoes 🍅 | 28 oz | Canned, crushed by hand |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | High-quality, cold-pressed |
| Yellow Onion 🧅 | 1 whole | Finely diced for base |
| Garlic Cloves 🧄 | 6 cloves | Minced for depth |
| Dried Oregano 🌿 | 2 tsp | Mediterranean variety preferred |
| Dried Basil 🍃 | 2 tsp | Rubbed between fingers |
| Red Pepper Flakes 🌶️ | ½ tsp | Adjust to heat preference |
| Fine Sea Salt 🧂 | 2 tsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | 1 tsp | Coarse grind for texture |
| Tomato Paste 🍅 | 2 tbsp | For concentrated richness |
San Marzano tomatoes are non-negotiable here. Look for DOP certification on the can—this guarantees authentic Italian origin and superior quality. Eataly or Whole Foods consistently stock the best options (the good stuff, not the pre-crushed kind). The olive oil should be extra-virgin, cold-pressed for optimal flavor development. Avoid any oil labeled simply as ‘olive oil’ or ‘light olive oil’ as they lack the necessary depth.
No San Marzano tomatoes? Regular canned tomatoes at half the amount will work in a pinch, but expect a slightly sweeter result. Fresh tomatoes aren’t recommended—they lack the concentrated flavor of canned. Dried oregano and basil can be swapped for fresh at one-third the quantity. For heat, fresh chili can replace red pepper flakes (use sparingly).
Sauce keeps beautifully. Transfer to airtight containers and refrigerate for up to 1 week or freeze for 6 months. The flavor actually improves after a day as the herbs meld (worth the extra minute to let it sit).

Step-by-Step Instructions for Rao’s Red Sauce
Master this classic technique to achieve rich, authentic Italian flavor with every spoonful.
Step 1: Sauté the Aromatic Base
Heat the 0.25 cup extra-virgin olive oil in a heavy saucepan over medium-low heat. Add the finely diced yellow onion and cook for 8-10 minutes, stirring occasionally, until translucent and softened but not browned.
This slow cooking process develops the onion’s natural sweetness without caramelization, creating the perfect foundation for your sauce. The onion should become nearly invisible in the oil, melting into the base of your creation.
Step 2: Develop Flavor with Garlic and Spices
Add the 6 cloves minced garlic, 2 tsp dried oregano, 2 tsp dried basil, and 0.5 tsp red pepper flakes. Stir constantly for 1-2 minutes until the garlic releases its fragrance but doesn’t color.
Here’s the thing—the garlic should sizzle gently but never brown. I always rub the dried basil between my fingers as I add it to release its essential oils. The red pepper flakes will infuse a subtle heat that balances the sweetness of the tomatoes.
Step 3: Incorporate Tomato Paste and Tomatoes
Stir in the 2 tbsp tomato paste and cook for 2-3 minutes, allowing it to deepen in color and develop its natural sweetness. This step intensifies the umami flavor that defines authentic Italian sauces.
Add the 28 oz San Marzano whole peeled tomatoes, crushing them by hand as they go into the pot. Include all the juices from the can—this liquid is packed with concentrated tomato flavor. The tomatoes should bubble gently as they hit the hot base.
Step 4: Simmer to Perfection
Season with 2 tsp fine sea salt and 1 tsp freshly ground black pepper. Reduce heat to low and let the sauce simmer uncovered for 45-60 minutes, stirring occasionally to prevent sticking.
You’ll notice the sauce transform from a loose mixture to a rich, thick consistency. The oil will separate slightly at the surface when it’s ready. Taste and adjust seasoning if needed, though the San Marzano tomatoes typically require minimal adjustment.
Step 5: Finish and Serve
Remove from heat and let the sauce rest for 5-10 minutes before using. This allows the flavors to meld completely. The finished product should have a velvety texture with visible flecks of herbs and a deep, balanced flavor profile.
Use immediately over pasta or let cool completely before storing in airtight containers. This recipe yields enough for 4 servings, with each portion delivering that signature Rao’s depth of flavor.
Pro Tips For Making Raos Red Sauce
- Crush the Tomatoes: Use your hands to crush the San Marzano tomatoes—this releases more juice and creates a rustic texture that blends better than chopping.
- Bloom the Oregano: Add the dried oregano to the hot olive oil for 10-15 seconds before the onion goes in; this wakes up its flavor and prevents a dull, dusty taste.
- Simmer Low and Slow: After adding the tomatoes, keep the heat at a gentle simmer—any higher and the sauce can separate or turn bitter.
- Skip the Garlic Press: Slice the garlic cloves thin instead of pressing; they’ll infuse the oil without overpowering the sauce or burning.
Perfect Pairings for These Flavors
Pasta Pairings
This sauce clings beautifully to rigatoni or pappardelle, where its rich texture can coat every ridge and curve. I love using De Cecco bronze-die pasta for its rough surface that grabs the sauce. Cook 1 lb pasta in well-salted water until al dente. 🍝
Protein Additions
For a heartier meal, add Italian sausage (sweet or spicy) browned in a pan. Crumble ½ lb into the sauce during the last 10 minutes of simmering. Meatballs work too—simmer 12 pre-cooked meatballs in the sauce for 15 minutes to absorb flavors.
Bread Partners
Serve with crusty ciabatta or garlic bread to soak up every last drop. I toast slices of sourdough rubbed with 1 garlic clove and drizzled with olive oil. Warm focaccia also pairs wonderfully for dipping.
Cheese Finishes
Top with freshly grated Parmigiano-Reggiano or Pecorino Romano for a salty kick. I use a Microplane to create fine, fluffy shavings. For creamy texture, add ½ cup ricotta stirred into hot pasta before saucing.
Vegetable Sides
A simple arugula salad with lemon vinaigrette cuts through the richness. Toss 4 cups baby arugula with 2 tbsp olive oil, 1 tbsp lemon juice, and shaved Parmesan. Roasted broccolini with garlic also complements the flavors. 💫

Frequently Asked Questions
Can I use regular canned tomatoes instead of San Marzano?
Yes, but use half the amount and expect a slightly sweeter flavor. San Marzano tomatoes have less acidity and more meat, which creates that signature rich texture. Regular tomatoes work in a pinch though.
Why do you simmer the sauce uncovered?
It allows excess liquid to evaporate, concentrating the flavors. Covering would trap steam, making the sauce thin and watery. The uncovered method gives you that thick, velvety consistency.
Can I make this sauce ahead of time?
The flavor actually improves after 1-2 days in the fridge as the herbs meld. Store in an airtight container for up to 1 week or freeze for 6 months.
