Ingredients

  • Water
  • Kosher Salt
  • Dried Penne
  • Whole Garlic Cloves
  • Butter
  • Heavy Cream
  • Baby Spinach
  • Grated Parmesan

Make It Easy

  • Buy a 5 oz bag of baby spinach and dump the whole thing in – no measuring, no leftover half bag of spinach.
  • Buy pre-peeled garlic and store it in your freezer. You’ll always have garlic ready to go without the time to peel and stinky fingers.

Method

The secret to this dish is starting with the perfect amount of water which means you don’t need to drain a thing – no colander required! The sauce is made in the pan with the cooked pasta, and spinach is added at the end and wilts beautifully into the warm, creamy sauce.

This true one pot meal feels indulgent without being too heavy.

Tips for Success:

  1. Use a deep skillet to ensure the pasta cooks evenly.
  2. Stir frequently to ensure the noodles cook evenly.
  3. Add the spinach right at the end for the perfect wilted texture.
