Preheat your oven to 350°F (175°C) and get ready for some kitchen magic.
In a medium saucepan, melt 2 tablespoons of unsalted butter over medium heat. Stir in 1/4 cup of all-purpose flour until smooth. Gradually whisk in 1 cup of chicken broth and 1 cup of heavy cream until the mixture thickens and bubbles.
In a large bowl, combine your luscious sauce with 2 (14.5-ounce) cans of drained French-style green beans, 1 (8-ounce) can of drained sliced water chestnuts, crumbled bacon from 6 cooked slices, and 1/2 cup of shredded mild cheddar cheese. Mix until everything is combined.
Spread this delightful mixture into a greased 9×13-inch baking dish. Sprinkle 1 cup of French-fried onions on top to crown your creation.
Place the casserole in the preheated oven and bake for 20-30 minutes, or until bubbly and golden with a crispy onion topping.
For extra flair, sprinkle more crumbled bacon on top before serving. Your casserole is now ready to impress!
Leftover green bean casserole can be stored in an airtight container in the refrigerator for up to 3 days.
To reheat, place the casserole in the oven at 350°F (175°C) for about 15-20 minutes until warmed through. You may want to add a few extra French-fried onions on top before reheating for extra crunch.
Feel free to customize this casserole by adding sautéed mushrooms or substituting a different cheese for a unique flavor.
