Vibrant rotini pasta with tomatoes and spinach, all cooked together in a single pot for easy preparation and serving.

# What You’ll Need:

→ Pasta

01 - 12 oz rotini pasta, uncooked

→ Vegetables

02 - 14 oz canned diced tomatoes with juices
03 - 3.5 oz fresh baby spinach
04 - 1 medium onion, finely chopped
05 - 3 cloves garlic, minced

→ Liquids

06 - 4 cups vegetable broth

→ Seasonings

07 - 2 tbsp olive oil
08 - 1 tsp dried oregano
09 - 1/2 tsp dried basil
10 - 1/4 tsp crushed red pepper flakes
11 - Salt and black pepper to taste

→ Cheese

12 - 1/2 cup grated Parmesan cheese, plus more for serving

# How to Make It:

01 - Heat olive oil in a large pot over medium heat. Add chopped onion and cook for 3-4 minutes until softened and translucent.
02 - Stir in minced garlic and cook for 1 minute until fragrant, being careful not to burn it.
03 - Add diced tomatoes with juices, vegetable broth, dried oregano, dried basil, red pepper flakes, salt, and pepper. Stir thoroughly to combine all ingredients.
04 - Bring the mixture to a boil, then add rotini pasta. Stir well to ensure pasta is submerged in liquid.
05 - Reduce heat to medium-low and simmer uncovered for 10-12 minutes, stirring occasionally, until pasta is al dente and most liquid is absorbed.
06 - Stir in fresh spinach and cook for 1-2 minutes until just wilted and incorporated throughout the dish.
07 - Add grated Parmesan cheese and stir until melted and creamy, creating a cohesive sauce coating the pasta.
08 - Taste the dish and adjust seasoning with additional salt and pepper as needed. Serve hot, topped with extra Parmesan cheese if desired.

# Expert Tips:

01 -
  • The pasta absorbs all those tomato flavors while cooking, creating depth that usually takes hours of simmering to achieve
  • Cleanup is so minimal you might actually look forward to doing dishes afterward
  • Its one of those rare recipes that tastes even better as leftovers the next day
02 -
  • The pasta will continue absorbing liquid even after you turn off the heat, so do not let it get too dry while cooking
  • If the pasta looks done but there is still too much liquid, just keep cooking for another minute or two
  • Stir more frequently toward the end, as the starch from the pasta can make things stick to the bottom
03 -
  • Use a pot that is wider than it is tall so the liquid evaporates more evenly as the pasta cooks
  • If you only have larger tomatoes, crush them with your hands before adding them to the pot
  • Grating your own Parmesan makes a huge difference compared to pre-grated cheese
