This arrabbiata sauce is a classic Roman pasta sauce that delivers bold, fiery flavor from just five pantry staples. Crushed red pepper flakes are bloomed in fruity extra-virgin olive oil with thinly sliced garlic, then simmered with hand-crushed San Marzano tomatoes until thick, rich, and deeply concentrated. Ready in 35 minutes, it is naturally vegan, gluten-free, and freezer-friendly — the kind of sauce that tastes like it came straight out of a Roman trattoria.
12ozpenne pasta - 340–450g (12–16 oz); penne rigate is traditional
Pecorino Romano or Parmesan cheese - finely grated; optional topping
Instructions
Pour canned San Marzano tomatoes into a large bowl and crush them by hand until you have a rough, chunky pulp — keep all the juices. Thinly slice the garlic cloves, chop the parsley, and tear the basil leaves; set aside.
Warm the olive oil in a large skillet over medium-low heat, add the sliced garlic, and cook gently for 2–3 minutes until pale golden and fragrant — do not let it brown. Add the crushed red pepper flakes and stir constantly for 30–60 seconds until the oil turns reddish-orange.
Carefully add the crushed tomatoes and all their juices to the skillet, then stir in the tomato paste, kosher salt, and black pepper until fully combined. The sauce will come to a fast bubble — let it bubble for 30 seconds.
Reduce heat to medium-low and simmer the sauce uncovered for 25–30 minutes, stirring every 5 minutes, until thickened and the oil just begins to separate at the edges. Break up any remaining large tomato chunks with a spoon, or blend for a smoother texture.
Bring a large pot of generously salted water to a rolling boil and cook the penne until al dente according to package directions, about 9–11 minutes. Before draining, reserve ½ cup (120ml) of starchy pasta cooking water, then drain the pasta.
Stir the chopped parsley and torn basil into the sauce, then add the drained penne and toss over medium heat for 1–2 minutes, adding splashes of reserved pasta water as needed for a silky, glossy consistency. Serve immediately topped with freshly grated Pecorino Romano or Parmesan.
Notes
Never rush the garlic — keep the heat at medium-low and pull the pan off the heat momentarily if needed. Burnt garlic will make the entire sauce bitter and cannot be fixed.
Blooming the red pepper flakes in the oil is non-negotiable for authentic arrabbiata flavor. Adding them with the tomatoes produces flat, sharp heat rather than the deep, rounded warmth this sauce is known for.
Use DOP-certified whole San Marzano tomatoes and crush them by hand for the best texture and sweetness. Pre-crushed canned tomatoes tend to be more acidic and less flavorful.
Save the pasta cooking water before draining — the starchy, salty liquid is the best tool for adjusting sauce consistency and helping the sauce cling beautifully to the pasta.
Start with 1 teaspoon of red pepper flakes and taste at the end of cooking before adding more. It is easy to increase heat but impossible to reduce it.
Refrigerate cooled sauce in an airtight container for up to 5–7 days, or freeze in 1-cup (240ml) portions for up to 3 months.
To reheat, warm gently in a saucepan over medium-low heat with a splash of water, or microwave in 60-second intervals, stirring between each.
For extra umami depth, add 2–3 oil-packed anchovy fillets to the oil along with the garlic — they melt in completely and add savory complexity without any fishy flavor.
Penne rigate (ridged penne) is the most traditional pasta pairing because its ridges trap the chunky sauce. Rigatoni, spaghetti, and bucatini are also excellent options.
This sauce also works beautifully as a pizza sauce, a braising liquid for chicken or sausage, or a spicy dipping sauce for garlic bread and mozzarella sticks.
