Ingredients

Instructions

  1. Step 1: Heat 2 tbsp olive oil in a large deep skillet over medium-high heat. Add 1 lb cut chicken breasts and cook for 5-6 minutes until browned and cooked through. Remove chicken and set aside.
  2. Step 2: In the same skillet, add 1 diced medium onion and 4 minced garlic cloves. Sauté for 3 minutes until fragrant and translucent. Stir in 1 tsp red pepper flakes and cook for 30 seconds.
  3. Step 3: Add 8 oz dried fettuccine pasta, 3 cups chicken broth, and 1 cup heavy cream to the skillet. Stir to combine and bring to a gentle boil.
  4. Step 4: Reduce heat to medium-low and simmer uncovered for 12-15 minutes, stirring occasionally, until pasta is tender and sauce thickens.
  5. Step 5: Stir in the cooked chicken and 1 cup grated Parmesan cheese until cheese melts and sauce coats pasta evenly. Season with salt and black pepper to taste.
  6. Step 6: Remove from heat and garnish with 2 tbsp chopped fresh parsley before serving.
