Heat the dutch oven, and add 1 Tbsp of olive oil. Add half of the chicken to brown for approximately 2 minutes per side just until it is no longer pink. Season while cooking (adding salt and pepper). Repeat with the second batch of chicken. Set it aside.
Add the remaining oil to the dutch oven. Saute the onions and the garlic for 5 minutes.
Now add the pumpkin puree, chicken broth, and the seasonings: salt, pepper, chili flakes, and nutmeg, mix.
Stir in the pasta and the chicken. Let it cook covered for 15 to 20 minutes, stirring occasionally.
Check the pasta, once it is done turn off the heat. And mix in the cream cheese.
Serve with some fresh chopped parsley and grated parmesan cheese. Enjoy!
