Recipe Information
Ingredients
- 900 grams fresh green beans
- 4 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 480 milliliters whole milk
- 120 milliliters heavy cream
- 100 grams sharp cheddar cheese, shredded
- 50 grams Parmesan cheese, grated
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1.5 teaspoons salt
- 1 teaspoon black pepper
- 100 grams panko breadcrumbs
- 2 tablespoons olive oil
- 2 tablespoons fresh parsley, chopped (optional garnish)
Instructions
Preheat your oven to 190°C (375°F).
Trim the ends of the green beans and blanch them in boiling, salted water for 4 minutes. Drain and immediately transfer them to a bowl of ice water to stop the cooking process. Drain the green beans again and set them aside.
In a medium saucepan, melt the butter over medium heat. Once melted, whisk in the flour, stirring constantly to form a roux. Cook for 2 minutes, until the roux is lightly golden.
Gradually pour in the milk and heavy cream, whisking constantly to ensure no lumps form. Bring the mixture to a gentle simmer and cook until slightly thickened, about 5 minutes.
Stir in the cheddar cheese, Parmesan cheese, garlic powder, onion powder, salt, and pepper. Mix until the cheeses are fully melted and the sauce is smooth. Remove from heat.
In a large mixing bowl, toss the blanched green beans with the cheese sauce until fully coated.
Transfer the green beans and cheese sauce mixture into a greased 9x13-inch (23x33 cm) baking dish, spreading it out evenly.
In a small bowl, combine the panko breadcrumbs and olive oil. Sprinkle the breadcrumb mixture evenly over the top of the green beans.
Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and crispy.
Remove the gratin from the oven and let it rest for 5 minutes before serving. Garnish with freshly chopped parsley, if desired.
