Ingredients
- 4 pieces (about 6 oz each) boneless skinless chicken breasts
- 2 tbsp olive oil
- 6 whole garlic cloves
- 4 tbsp butter
- 3 tbsp all-purpose flour
- 2 cups whole milk
- 1 cup finely grated Parmesan cheese
- 1 cup shredded mozzarella cheese
- 4 cups packed fresh spinach
- 1 1/2 tsp salt
- 1 tsp black pepper
- 1 tsp dried Italian seasoning
- 1/4 tsp (optional) red pepper flakes
Instructions
- Step 1: Preheat oven to 375°F. Toss 6 whole garlic cloves with 1 tbsp olive oil, wrap in foil and roast for 20 minutes until soft and fragrant.
- Step 2: Heat 2 tbsp olive oil in a large skillet over medium-high heat. Season 4 chicken breasts with 1 tsp salt, 1/2 tsp black pepper, and 1 tsp Italian seasoning. Sear chicken for 4 minutes per side until golden but not fully cooked, then set aside.
- Step 3: In a saucepan over medium heat, melt 4 tbsp butter. Whisk in 3 tbsp flour and cook for 1-2 minutes until bubbling and light golden. Gradually add 2 cups whole milk, whisking constantly until sauce thickens and coats the back of a spoon, about 5 minutes.
- Step 4: Squeeze roasted garlic cloves into the sauce and stir in 1 cup Parmesan cheese, 1 tsp salt, 1/2 tsp black pepper, and 1/4 tsp red pepper flakes. Remove from heat.
- Step 5: In a large baking dish, arrange the seared chicken breasts and scatter 4 cups fresh spinach around them. Pour the Alfredo sauce evenly over chicken and spinach.
- Step 6: Sprinkle 1 cup shredded mozzarella cheese on top. Bake uncovered for 20-25 minutes until chicken is cooked through (internal temp 165°F) and cheese is bubbly and golden.
- Step 7: Let rest 5 minutes before serving to allow sauce to thicken slightly and flavors to meld.
