  1. 1

    Heat the oven to 350 degrees F (175 degrees C).

    Bring a pot of lightly salted water to a boil. Cook the broccoli in the boiling water for 1 minute. Drain and set aside.

  3. 3

    In a saucepan over medium heat, combine the cheese, cream of mushroom soup, salt, and pepper. Stir until the cheese melts. Add the broccoli and stir to coat. Transfer the mixture to a 9x13-inch baking dish.

  4. 4

    In a separate saucepan, melt the butter over medium heat. Stir in the croutons, then sprinkle them over the broccoli mixture.

    Bake for 30 minutes in the preheated oven, until the topping is browned and the broccoli is tender.
