Recipe Information
Ingredients
- 1 pound fresh green beans
- 3 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1.5 cups whole milk
- 0.5 cup heavy cream
- 0.5 teaspoon garlic powder
- 0.5 teaspoon onion powder
- 0.25 teaspoon ground black pepper
- 0.5 teaspoon salt
- 1 cup shredded Gruyère cheese
- 0.5 cup grated Parmesan cheese
- 0.75 cup panko breadcrumbs
- 1 tablespoon olive oil
- 2 tablespoons fresh parsley, chopped (optional for garnish)
Instructions
Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish.
Bring a large pot of salted water to a boil. Add the green beans and blanch them for 4-5 minutes until they are crisp-tender. Drain and transfer to a bowl of ice water to stop the cooking process. Once cooled, drain and set aside.
In a medium-sized saucepan, melt 2 tablespoons of unsalted butter over medium heat. Once melted, whisk in the flour and cook for 1-2 minutes to form a roux, stirring constantly.
Gradually whisk in the milk and heavy cream, ensuring the mixture remains smooth. Cook for 3-4 minutes until the sauce thickens.
Stir in garlic powder, onion powder, black pepper, and salt. Then add the Gruyère and Parmesan cheeses, stirring until melted and fully incorporated into a smooth cheese sauce.
In the prepared baking dish, arrange the blanched green beans evenly. Pour the cheese sauce over the green beans, ensuring they are well coated.
In a small bowl, combine the panko breadcrumbs with 1 tablespoon of melted butter (or olive oil). Mix until the breadcrumbs are evenly coated, then sprinkle them over the green bean mixture in the baking dish.
Bake in the preheated oven for 15-20 minutes, or until the top is golden brown and bubbling.
Remove from the oven and let cool for 5 minutes. Optionally, garnish with chopped parsley before serving.
