Ingredients

• 4 pieces Chicken breasts
• 6 cups Fresh spinach
• 2 tablespoons Olive oil
• 3 cloves Garlic
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 4 tablespoons Unsalted butter
• 2 tablespoons All-purpose flour
• 1.5 cups Chicken broth
• 1 cup Heavy cream
• 1 cup Parmesan cheese, grated
• 1.5 cups Mozzarella cheese, shredded
• 0.5 cup Panko breadcrumbs
• 1 tablespoon Lemon juice
• 0.5 teaspoon Paprika

Directions

Step 1

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish and set aside.

Step 2

Heat 1 tablespoon of olive oil in a large skillet over medium heat. Season the chicken breasts with 1/2 teaspoon of salt and 1/4 teaspoon of black pepper and sear for 4-5 minutes on each side until golden but not fully cooked. Remove and set aside.

Step 3

In the same skillet, add the remaining 1 tablespoon of olive oil and minced garlic. Sauté for 30 seconds until fragrant, then add the fresh spinach and cook until wilted, about 2-3 minutes. Set the spinach aside.

Step 4

In a medium saucepan, melt the butter over medium heat. Stir in the flour and cook for 1-2 minutes to form a roux, whisking constantly.

Step 5

Slowly whisk in the chicken broth and heavy cream, ensuring no lumps form. Cook for 3-4 minutes until the sauce thickens.

Step 6

Stir in the grated Parmesan cheese, lemon juice, paprika, and the remaining 1/2 teaspoon of salt and 1/4 teaspoon of black pepper. Turn off the heat.

Step 7

Layer the wilted spinach in the prepared baking dish. Place the seared chicken breasts on top of the spinach.

Step 8

Pour the prepared cream sauce over the chicken and spinach, spreading it evenly.

Step 9

Sprinkle the shredded mozzarella cheese over the top, followed by the panko breadcrumbs for a little crunch.

Step 10

Bake in the preheated oven for 30-35 minutes, or until the casserole is bubbly and the chicken is fully cooked through (internal temperature of 165°F or 74°C).

Step 11

Allow the casserole to cool for 5 minutes before serving. Enjoy!
