Sprinkle blackening seasoning on both sides of chicken. Heat olive oil in a cast iron skillet over medium high heat. Add chicken and cook about 5 minutes per side or until cooked all the way through. Remove chicken from pan and keep warm.
Add butter to the skillet and cook garlic and red pepper over medium heat until pepper is starting to soften, about 2 minutes.
Add heavy cream and simmer for 5 minutes.
Turn heat to low and add cream cheese and parmesan cheese, plus all seasonings. Stir well to melt and blend in the cream cheese and parmesan cheese. Once sauce is smooth, add cooked fettuccine to the pan and toss to coat.
Divide fettuccine between 4 plates, top with chicken and grated Parmesan cheese.
