Part 4/6:

Next, increase the heat and add Italian sausage to the pan, breaking it up as it cooks. Combine this with diced onions and allow them to caramelize. After approximately 7 minutes, add crushed red pepper flakes for extra flavor.

Deglazing the Pan

Pour in 1/2 cup of dry white wine, scraping up the flavorful brown bits at the bottom of the pan while letting it simmer. Once the wine has evaporated a bit, add the jar of puree, which can also be substituted with crushed tomatoes or tomato paste for a similar effect.

Bringing It All Together

As the sauce simmers, check the pasta, removing it just before it reaches the desired doneness. When ready, transfer the pasta directly into the sauce, adding some reserved pasta water if necessary to achieve the right consistency.
