A hearty and comforting casserole made with tender chicken, green beans, and mushrooms in a creamy smoked Gouda sauce, topped with crispy fried onions.

Ingredients

Scale
  • 3 tablespoons unsalted butter
  • 1 large yellow onion, peeled and diced
  • 8 ounces mushrooms, sliced thin
  • 2 cloves garlic, peeled and minced
  • 3 tablespoons all-purpose flour
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 1 ½ cups chicken broth
  • 1 ½ cups half and half
  • 1 cup smoked Gouda, shredded
  • 4 cups cooked chicken, cubed
  • 10-ounce bag frozen green beans, thawed
  • 2 cups fried onions, divided
  • Non-stick cooking spray

Instructions

1. Preheat the oven to 350°F (177°C). Prepare a 9″ x 13″ casserole dish with non-stick cooking spray.

2. In a medium-sized skillet over medium-high heat, melt the butter.

3. Add diced onion and sauté for about 5 minutes until softened.

4. Stir in sliced mushrooms and cook for another 3-4 minutes until soft.

5. Add minced garlic and cook for 30 seconds to blend flavors.

6. Stir in flour, salt, and pepper until the onion mixture is well coated.

7. Slowly add chicken broth, stirring constantly until the mixture thickens.

8. Reduce heat to low and stir in half and half.

9. Add shredded smoked Gouda and stir until melted and the sauce is thickened.

10. In a large mixing bowl, combine cubed chicken, thawed green beans, and 1 cup of fried onions.

11. Pour the mushroom sauce over the mixture and stir until evenly coated.

12. Transfer the mixture to the prepared casserole dish and spread evenly.

13. Bake uncovered for 30 minutes.

14. Top with the remaining 1 cup of fried onions and bake for 5 more minutes until golden and bubbly.

15. Remove from oven and let rest for 5 minutes before serving.

Notes

Make sure the green beans are thawed and well-drained to avoid a watery casserole.

You can substitute the chicken with white beans for a vegetarian version.

For extra crunch, try topping with crushed crackers instead of fried onions.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.

Reheat in the microwave at 50% power for 1-2 minutes or in a 350°F oven for 10-15 minutes.
