Bring a large pot of salted water to a boil. Cook the fettuccine until al dente according to package directions. Drain, reserving Β½ cup of the pasta water, and set aside.
Season the diced chicken with Cajun seasoning, salt, and pepper. Make sure each piece is well-coated for maximum flavor.
Heat olive oil in a large skillet over medium-high heat. Add the seasoned chicken in a single layer and cook for 6β8 minutes until golden and cooked through. Remove chicken from the skillet and set aside.
Stir in honey and simmer gently for 1 minute. Then, pour in heavy cream and stir until the mixture is smooth and slightly thickened, about 2β3 minutes.
Return the chicken to the skillet, tossing to coat it in the sauce. Add the cooked fettuccine and toss everything together until the noodles are well coated. If the sauce is too thick, add some reserved pasta water to reach your desired consistency.
Garnish with chopped parsley if desired and serve hot.
Notes
Feel free to substitute the fettuccine with any pasta shape you prefer. Use fresh ingredients for the best flavor.
