# Expert Advice:

01 -
  • Every bite is coated in a rich, tomatoey sauce that clings to the pasta without needing a separate pan for the sauce.
  • The whole thing cooks in one pot, which means less scrubbing and more time to actually enjoy your meal.
  • It comes together in half an hour, so you can have a hearty dinner on the table even on your busiest nights.
  • The spinach adds a pop of color and a boost of greens without feeling like you're trying too hard to be healthy.
02 -
  • Stir the pasta every few minutes or it'll stick to the bottom of the pot and burn, especially once the liquid starts to reduce.
  • If the pasta absorbs the liquid too fast and still feels hard, add a splash more broth or water and keep simmering until it's tender.
  • Don't add the spinach too early or it'll overcook and turn slimy, wait until the pasta is done and just wilt it at the end.
03 -
  • Use a wide, shallow pot instead of a tall one so the pasta cooks more evenly and you can stir without splashing.
  • Taste the broth before you add the pasta and adjust the salt then, because once the pasta goes in, it's harder to fix.
  • Let the dish rest for a minute or two off the heat before serving, it thickens up just a bit and the flavors settle into each other beautifully.
