Ingredients
Scale
- 1.5 pounds Russet potatoes, peeled and thinly sliced (about 1/8-inch thick)
- 1 tablespoon olive oil
- 1 small yellow onion, finely chopped
- 2 tablespoons all-purpose flour
- 1.5 cups whole milk, warmed
- 1 cup sour cream
- 1/2 teaspoon salt, or to taste
- 1/4 teaspoon black pepper, or to taste
- 1/4 teaspoon paprika
- 1/4 teaspoon garlic powder
- 1 cup shredded sharp cheddar cheese, divided
- 2 tablespoons chopped fresh chives or parsley, for garnish (optional)
Instructions
- 1. Preheat oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
- 2. Heat olive oil in a medium saucepan over medium heat. Add chopped onion and cook until softened and translucent, about 5-7 minutes. Stir in garlic powder during the last minute.
- 3. Sprinkle flour over the cooked onions. Cook, stirring constantly, for 1 minute.
- 4. Gradually whisk in warmed milk until smooth, then cook, stirring, until sauce thickens to coat the back of a spoon (5-8 minutes).
- 5. Remove from heat. Stir in sour cream, salt, pepper, and paprika until smooth.
- 6. Stir in 1/2 cup shredded cheddar cheese until melted.
- 7. Layer half the sliced potatoes in the baking dish. Pour half the sauce over.
- 8. Layer remaining potatoes, then pour remaining sauce over.
- 9. Sprinkle remaining 1/2 cup cheddar cheese on top.
- 10. Cover baking dish tightly with foil and bake for 45 minutes.
- 11. Remove foil and bake for another 15-20 minutes, until potatoes are tender and cheese is golden and bubbly.
- 12. Let rest for 5-10 minutes before serving. Garnish with chives or parsley if desired.
Notes
Store cooled leftovers in an airtight container in the refrigerator for 3-4 days. Reheat in the oven at 325°F (160°C), covered with foil, adding a tablespoon or two of milk or cream to revive the sauce. Leftovers can be used as a base for potato hash, a casserole, or a soup thickener.
