Green Bean Chicken Casserole

Preheat the oven to 350 degrees. Grease the 9x13 casserole dish with nonstick cooking spray.

In a medium skillet over medium high heat, melt the butter. Add the mushrooms and onion to the skillet. Cook for 5 to 6 minutes or until the vegetables are softened.

Stir in the garlic.

Add the flour, salt, and pepper to the medium skillet and stir everything to coat the onions and mushrooms.

Once the flour is fully incorporated, add in the chicken stock. Continue stirring until the mixture begins to thicken.

Add the half and half. Reduce the heat and stir until the sauce has thickened enough to coat the back of a spoon. Add Gouda and stir to combine.

In a large bowl, mix the green beans, chicken, and 1 cup of fried onions.

Mix in the sauce and stir until everything is evenly coated.

Transfer the mixture to the casserole dish and spread it evenly.

Bake uncovered for 30 minutes.

Top the casserole with the remaining fried onions and bake for 5 minutes more.
