Ingredients

  • 2 lbs Chicken Breast
  • 3/4 lbs fettuccine pasta (or angel hair or vermicelli pasta)
  • 1 lb white mushrooms thickly sliced
  • 1 small onion finely chopped
  • 3 cloves garlic minced
  • 3 1/2 cups half and half *
  • 1/4 cup parsley, finely chopped, plus more for garnish
  • 1 tsp sea salt or to taste, plus more for pasta water
  • 1/4 tsp black pepper or to taste
  • 3 Tbsp olive oil divided
  • 1 Tbsp butter

Instructions

  1. Cook fettuccini in a pot of salted water (4 qts water, 1 Tbsp salt,) according to package instructions then drain and set aside.

  2. Meanwhile, slice chicken into strips and season all over with salt and pepper. In a large skillet, heat 2 Tbsp olive oil over medium/high heat and sauté chicken until lightly golden and cooked through (5 min). Remove chicken from the pan and cover to keep warm.

  3. In the same pan over medium/high, heat 1 Tbsp olive oil and 1 Tbsp of butter. Add onion and sauté 3 min until soft. Add sliced mushrooms and sauté until soft (5-7 min), stirring frequently. Add garlic and sauté 30 seconds, stirring constantly.

  4. Add half-n-half and simmer over medium/high heat 6-10 min, or until barely beginning to thicken. Add chicken back to the pan, add 1/4 cup parsley and season sauce to taste (1/2 to 1 tsp salt and 1/4 tsp pepper).

  5. Add cooked pasta and stir to combine. Heat another minute until warmed through then turn off the heat, cover and let rest 10-15 minutes then stir and serve garnished with parsley.
