Chicken and Peas Au Gratin Casserole

• 2 tablespoons olive oil
• 3 cups cubed skinless, boneless chicken
• 4 cups torn bread pieces
• 1 cup shredded Cheddar cheese
• 1/4 cup butter, melted
• 2 cups frozen peas
• 1/4 cup butter
• 1/2 cup all-purpose flour
• 3 cups milk
• 2 teaspoons salt
• 1/2 teaspoon black pepper

1. Preheat an oven to 350 degrees F (175 degrees C).
2. Heat the olive oil in a skillet over medium heat.
3. Cook the chicken until no longer pink in the center and the juices run clear, 5 to 7 minutes; drain and set aside.
4. Toss the bread pieces, Cheddar cheese, and 1/4 cup melted butter together in a bowl; spread about half of the mixture into the bottom of a 9x13-inch baking dish.
5. Layer the peas and chicken atop the bread layer.
6. Melt 1/4 cup butter in a saucepan over medium heat; stir the flour, milk, salt, and pepper into the melted butter.
7. Cook and stir the sauce until smooth and thick, 5 to 7 minutes.
8. Pour over the casserole.
9. Top with the remaining bread mixture.
10. Bake in the preheated oven until the top begins to brown, 30 to 40 minutes.
