Directions
You’ll love how easy it is to make this delightful cheesy green beans au gratin dish! Start by preheating your oven to 350 degrees F. This ensures your green bean gratin will cook evenly. Now it’s time to make the cheese sauce. In a skillet, over medium heat, melt the butter. Whisk in the flour, salt, and dry mustard.
Cook until the mixture becomes bubbly, infusing the base with flavor. Gradually add the milk, stirring continuously until the sauce is smooth.Add the diced cheddar cheese to the sauce and stir until it’s completely melted. This cheesy goodness is the heart of the dish.

Add your precooked fresh green beans to the mix. Stir gently to ensure they’re fully coated with the luscious cheese sauce. Transfer the green bean mixture into a buttered baking dish. This step is crucial for that perfect gratin texture.
Sprinkle a generous layer of shredded parmesan cheese over the top. This will give your gratin a golden brown and crispy finish. Bake in the oven for about 30 minutes. You’re looking for a bubbly interior and a golden-brown crust.
