Step 1

Cook the chicken: Heat the oil in a large skillet over medium-high heat. Add the chicken and until the chicken starts to brown, about 5 minutes. Add the onion and cook for another 3 minutes until it softens and becomes translucent. Stir in the red pepper flakes and garlic and cook for another 30 seconds until aromatic.

Step 2

Finish the pasta: Add the rest of the ingredients to the pot, including the penne, and stir. Bring everything a boil then reduce the heat to a simmer and cook for 15-20 minutes, stirring occasionally. Add more broth if needed, though mine had enough liquid.

Step 3

Garnish and serve: Top with basil, parmesan cheese, and serve.
