Detailed Directions and Instructions
Prepare the Casserole Dish
Preheat your oven to 350°F (175°C) and lightly grease a 9×13 inch casserole dish.
Cook the Green Beans
In a large pot, bring water to a boil and add the green beans. Cook for about 5 minutes until they are bright green and tender. Drain and set aside.
Make the Cheese Sauce
In a medium saucepan, melt butter over medium heat. Add flour and stir continuously to make a roux. Cook for about 1 minute. Gradually whisk in milk, ensuring there are no lumps. Continue to cook and stir until the mixture thickens.
Add Cheese to the Sauce
Remove the saucepan from heat and stir in shredded cheese until fully melted. Add salt and pepper to taste.
Combine Ingredients
In a large bowl, mix the cooked green beans, cooked macaroni, and cheese sauce until well combined. Pour this mixture into the prepared casserole dish.
Prepare the Topping
In a small bowl, combine breadcrumbs and melted butter. Mix well and sprinkle the breadcrumb mixture evenly over the casserole.
Bake the Casserole
Place the casserole dish in the preheated oven. Bake for 25-30 minutes, or until the top is golden brown and the casserole is bubbly.
Let it Cool
Once baked, remove the casserole from the oven and let it cool for about 5-10 minutes before serving.
