Ingredients
Method
Prep first.
- Bring a large pot of salted water to a boil. Finely chop the red onion and measure out your ingredients.
Soften the onion.
- Heat olive oil in a large skillet over medium heat. Add chopped onion and cook for 3–4 minutes until soft and translucent.
Add the ’nduja.
- Stir in the ’nduja paste and let it melt into the onions for about 30–60 seconds, releasing its smoky chili aroma.
Add tomato passata.
- Pour in the tomato passata and a splash of water. Stir and simmer gently.
- For a bright, fresh sauce, simmer 5 minutes.
- For a richer, deeper sauce, simmer 20–30 minutes.
Cook the pasta.
- While the sauce simmers, cook your pasta in the boiling water until just shy of al dente. Reserve 1 cup of pasta water before draining.
Combine pasta and sauce.
- Add drained pasta to the skillet with the sauce. Toss well over medium heat, adding small splashes of pasta water until the sauce clings and turns glossy.
Finish and serve.
- Remove from heat. Stir in a knob of butter if you like extra shine. Add grated cheese, torn basil, and a drizzle of olive oil. Serve immediately.
Notes
- Adjust the heat by using less ’nduja or stirring in butter or cream at the end.
- Save your pasta water — it’s key for a silky, restaurant-style sauce.
- Rigatoni and fileja grip this sauce best, but spaghetti works fine if well-tossed.
- Pecorino gives a saltier punch, Parmesan adds nuttiness — both are great choices.
- The sauce freezes beautifully for up to 3 months.
