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)

Directions

Step 1

Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish.

Step 2

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.

Step 3

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.

Step 4

Gradually whisk in the milk and heavy cream, ensuring the mixture remains smooth. Cook for 3-4 minutes until the sauce thickens.

Step 5

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.

Step 6

In the prepared baking dish, arrange the blanched green beans evenly. Pour the cheese sauce over the green beans, ensuring they are well coated.

Step 7

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.

Step 8

Bake in the preheated oven for 15-20 minutes, or until the top is golden brown and bubbling.

Step 9

Remove from the oven and let cool for 5 minutes. Optionally, garnish with chopped parsley before serving.
