Ingredients
- 1 lb, cut into 1-inch pieces boneless skinless chicken breasts
- 8 oz fettuccine pasta
- 3 cups baby spinach
- 8 oz sliced cremini mushrooms
- 4 minced garlic cloves
- 3 tbsp unsalted butter
- 2 tbsp all-purpose flour
- 2 cups whole milk
- 1 cup chicken broth
- 1 cup freshly grated Parmesan cheese
- 2 tbsp olive oil
- 1 tsp, divided salt
- 1/2 tsp, divided black pepper
- 1/4 tsp optional red pepper flakes
Instructions
- Step 1: Heat 2 tbsp olive oil in a large deep skillet over medium-high heat. Add 1 lb chicken breast pieces seasoned with 1/2 tsp salt and 1/4 tsp black pepper. Cook for 5-6 minutes until golden and cooked through. Remove chicken and set aside.
- Step 2: In same skillet, melt 3 tbsp unsalted butter over medium heat. Add 4 minced garlic cloves and 8 oz sliced cremini mushrooms. Sauté for 4-5 minutes until mushrooms are tender and garlic is fragrant.
- Step 3: Stir in 2 tbsp all-purpose flour and cook for 1-2 minutes to form a roux, stirring constantly until slightly golden.
- Step 4: Gradually whisk in 2 cups whole milk and 1 cup chicken broth, stirring continuously until sauce thickens and coats the back of a spoon, about 4-5 minutes.
- Step 5: Add 8 oz fettuccine pasta broken in half, pressing under the sauce. Reduce heat to medium-low, cover, and simmer for 12-14 minutes, stirring occasionally, until pasta is al dente and most liquid absorbed.
- Step 6: Stir in 1 cup grated Parmesan cheese, cooked chicken, and 3 cups baby spinach. Cook for 2 more minutes until spinach wilts and cheese melts. Season with remaining 1/2 tsp salt, 1/4 tsp black pepper, and 1/4 tsp red pepper flakes if using.
- Step 7: Serve immediately garnished with extra Parmesan if desired.
