Notes
Starchy pasta water helps emulsify the sauce and stick to the pasta. Reserve pasta water and add a little at a time, over heat, until the sauce reaches your desired consistency.
Substitutions and Variations
Pasta - Use the noodle of your choice. Rotini, rigatoni, large macaroni, bow tie pasta all work well.
Oil - Use extra virgin olive oil or substitute with truffle oil for rich, decadent flavor.
Chicken - Chicken breasts or tenders cut into cubes or substitute rotisserie chicken for a simple shortcut.
Garnish - Top with gremolata, lemon zest or a squeeze of fresh lemon juice for a hint of bright flavor.
Storage Notes
Store pasta in an airtight container refrigerated up to 3 days. To reheat, add a small amount of heavy cream to a sauce pan over medium heat and toss in pasta until warm and creamy.
