Recipe Information
Ingredients
- 450 grams green beans, trimmed and cut into 2-inch pieces
- 450 grams russet potatoes, peeled and diced into 1-inch cubes
- 3 tablespoons butter
- 2 tablespoons all-purpose flour
- 300 ml milk
- 200 grams shredded cheddar cheese
- 120 ml sour cream
- 1 teaspoon salt
- 0.5 teaspoons black pepper
- 0.5 teaspoons garlic powder
- 1 cup crispy fried onions
- 1 tablespoon olive oil
Instructions
Preheat your oven to 180°C (350°F) and grease a 9x13-inch baking dish with a little olive oil or butter.
Bring a large pot of salted water to a boil. Add the diced potatoes and cook for 8-10 minutes, or until just tender. Remove the potatoes with a slotted spoon and set aside.
In the same pot of boiling water, add the green beans and blanch them for 4-5 minutes. Drain and set aside.
In a medium saucepan over medium heat, melt the butter. Whisk in the flour and cook for 1-2 minutes to form a roux.
Gradually add the milk to the roux, whisking constantly to avoid lumps. Cook for 3-4 minutes until the mixture thickens.
Remove the saucepan from the heat and stir in 150 grams of shredded cheddar cheese, sour cream, salt, black pepper, and garlic powder until smooth.
In the prepared baking dish, layer the green beans and potatoes evenly. Pour the cheese sauce over the top and gently toss to coat.
Sprinkle the remaining 50 grams of shredded cheddar cheese over the casserole, followed by the crispy fried onions.
Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly, and the top is golden brown.
Remove from the oven and let the casserole cool for 5 minutes before serving. Enjoy your Green Bean Potato Casserole!
