A comforting and hearty chicken broccoli casserole perfect for a family dinner. Tender chicken and fresh broccoli baked in a creamy sauce topped with melted cheese and crispy breadcrumbs.
3 cups cooked chicken breast, shredded or diced
4 cups fresh broccoli florets
1 cup white onion, finely chopped
2 cloves garlic, minced
1 can (10.5 ounces) condensed cream of mushroom soup
1 cup sour cream
1/2 cup mayonnaise
1 cup shredded sharp cheddar cheese
1/2 cup shredded mozzarella cheese
1/2 cup chicken broth
1 teaspoon salt
1/2 teaspoon black pepper
1/2 teaspoon dried thyme
1 cup plain breadcrumbs
2 tablespoons unsalted butter, melted
2 tablespoons olive oil
Preheat the oven to 350°F (175°C).
Steam the broccoli florets in a steamer basket over boiling water for 4-5 minutes until just tender. Drain and set aside.
In a large mixing bowl, combine the condensed cream of mushroom soup, sour cream, mayonnaise, chicken broth, salt, black pepper, dried thyme, and minced garlic. Stir until smooth.
Add the cooked chicken, steamed broccoli, and chopped onion to the sauce mixture. Stir gently to combine all ingredients evenly.
Fold in 1/2 cup of shredded cheddar cheese and 1/4 cup of shredded mozzarella cheese into the mixture.
Transfer the mixture into a greased 9×13 inch casserole dish and spread evenly.
In a small bowl, mix the breadcrumbs with melted butter and olive oil until the crumbs are evenly coated.
Sprinkle the breadcrumb mixture evenly over the casserole.
Top the casserole with the remaining 1/2 cup cheddar cheese and 1/4 cup mozzarella cheese.
Bake uncovered in the preheated oven for 35-40 minutes, or until the casserole is bubbly and the topping is golden brown.
Remove from the oven and let rest for 5 minutes before serving.
