To create this fantastic Buffalo Chicken Pasta, follow these straightforward steps:

1. Boil Pasta: In a large pot, cook the pasta according to package instructions until al dente. Drain and set aside.

2. Heat Oil: In the same pot, heat olive oil over medium heat.

3. Add Chicken: Stir in the shredded chicken, combining it with the oil. Cook for 2-3 minutes, allowing it to warm through.

4. Pour Sauce: Add the Buffalo sauce to the chicken, stirring to coat entirely.

5. Add Cream: Pour in the heavy cream, combining it thoroughly with the chicken and sauce mixture.

6. Incorporate Cheese: Gradually stir in both the cheddar and mozzarella cheeses until fully melted and creamy.

7. Combine Pasta: Add the cooked pasta back into the pot. Toss well to ensure the pasta is evenly coated with the cheesy Buffalo sauce.

8. Season: Taste and add salt and pepper as desired.

9. Garnish: Serve immediately, topping each portion with sliced green onions for added flavor.
