Step 1

Place a large stock pot or a Dutch oven over medium heat and heat the olive oil until hot, about 2 minutes.

Add the butter directly into the pot, scraping the bits of cooked chicken off the bottom of the pot.

Step 4

Add the onion and garlic and sauté until soft, about 5 minutes. Add the salt and pepper and stir.

Step 5

Add the water, heavy cream, and pasta and stir.

Step 6

Allow this to cook, stirring frequently for 9 minutes, or until the pasta is al dente.

Step 7

Stir in the cooked chicken and Parmesan.

Step 8

Serve immediately.
