Recipe Information
Ingredients
- 3 cups cooked turkey (shredded or diced)
- 4 cups fresh broccoli florets
- 1 can (10.5 oz) cream of mushroom soup
- 1 cup mayonnaise
- 1 cup sour cream
- 2 tablespoons lemon juice
- 2 cups grated cheddar cheese
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon salt
- 0.5 teaspoons black pepper
- 1 cup breadcrumbs
- 2 tablespoons butter (melted)
- 1 as needed cooking spray
Instructions
Preheat your oven to 350°F (175°C) and lightly grease a 9x13-inch casserole dish with cooking spray.
Bring a pot of salted water to a boil and blanch the broccoli florets for 2-3 minutes until they are bright green and slightly tender. Drain and set aside.
In a large mixing bowl, combine the cream of mushroom soup, mayonnaise, sour cream, lemon juice, garlic powder, onion powder, salt, and black pepper. Stir until smooth and well combined.
Fold in the cooked turkey and blanched broccoli into the mixture, making sure everything is evenly coated in the sauce.
Transfer the mixture into the prepared casserole dish, spreading it out evenly.
Sprinkle the grated cheddar cheese evenly over the top of the casserole.
In a small bowl, mix the breadcrumbs with the melted butter until the crumbs are lightly coated. Sprinkle the breadcrumb mixture evenly over the cheese layer.
Bake the casserole in the preheated oven for 30 minutes, or until the top is bubbly and golden brown.
Remove from the oven and let the casserole cool for 5-10 minutes before serving.
