08 - Taste and adjust seasoning as needed. Serve hot, topped with additional Parmesan if desired.

# Expert Tips:

01 -
  • The starch from the pasta thickens the tomato broth into a restaurant style sauce without any extra effort
  • Cleanup consists of exactly one pot and maybe a cutting board if youre feeling ambitious
  • It comes together in under 30 minutes but tastes like it simmered all afternoon
02 -
  • The pasta continues absorbing liquid even after you turn off the heat, so err on the side of slightly looser rather than too thick
  • If the sauce looks too thick before the pasta is done, add broth in 1/4 cup increments rather than water to maintain flavor
  • Stirring frequently during the last 5 minutes prevents the starch from settling on the bottom and burning
03 -
  • Reserve about 1/4 cup of pasta cooking liquid before stirring in the spinach, just in case you need to loosen the sauce later
  • Grate your own Parmesan rather than buying pre grated for the smoothest melting texture
