03 - 3.5 oz fresh baby spinach
04 - 1 medium onion, finely chopped

# How to Make It:

01 - Heat olive oil in a large pot over medium heat. Add chopped onion and cook for 3 to 4 minutes until softened.
02 - Stir in minced garlic and cook for 1 minute until fragrant.
03 - Add diced tomatoes with juices, vegetable broth, oregano, basil, crushed red pepper flakes if using, salt, and pepper. Stir to combine thoroughly.
04 - Bring the mixture to a boil, then add rotini pasta. Stir well to prevent sticking.
05 - Reduce heat to medium-low and simmer uncovered, stirring occasionally, for 10 to 12 minutes until pasta reaches al dente texture and most liquid is absorbed.
06 - Stir in fresh spinach and cook for 1 to 2 minutes until completely wilted.
07 - If using, add grated Parmesan cheese and stir until melted and creamy throughout.
08 - Taste and adjust seasoning as needed. Serve hot, topped with additional Parmesan if desired.

# Expert Suggestions:

01 -
  • The pasta absorbs all those tomato flavors while cooking, creating its own silky sauce without any extra work
  • Cleanup takes literally three minutes because you used exactly one vessel
  • It tastes like it simmered all day but comes together in half an hour
02 -
  • The pasta continues absorbing liquid even after you turn off the heat, so if it looks a little too soupy early on, do not panic
  • Stir more often than you think you need to, or the bottom will stick and burn
  • Vegetable broth brands vary wildly in salt content, so start with less and add more as needed
03 -
  • Grate your own Parmesan instead of buying pre grated, the texture difference is huge and it melts better
  • Use a pot with a heavy bottom if you have one, it distributes heat more evenly and prevents hot spots
