Au Gratin Potatoes
There's nothing like au gratin potatoes to take any meal over the top. The creamy, decadent, and oh-so satisfying recipe is sure to please everyone at your table.
Ingredients
- russet potatoes (4 medium)
- onion (1 medium)
- salt (0 )
- ground black pepper (0 )
- butter (3 tablespoons)
- all-purpose flour (3 tablespoons)
- milk (2 cups)
- shredded Cheddar cheese (1.5 cups)
Instructions
- Gather all ingredients. Preheat the oven to 400 degrees F (200 degrees C). Butter a 2-quart casserole dish.
- Layer half of the potatoes in the bottom of the prepared casserole dish; season with salt and pepper.
- Layer onion slices over top, then top with the remaining potatoes. Season again with salt and pepper.
- Melt butter in a medium saucepan over medium heat. Gradually whisk in flour and salt and cook, whisking constantly until raw flour flavor has cooked off, about 1 minute.
- Gradually add milk, about 1/4 cup at a time, whisking well after each addition to incorporate; the gradual addition and whisking of milk will help avoid lumps in your sauce.
- Cook, whisking constantly, until the mixture has thickened, 3 to 5 minutes.
- Stir in cheese all at once; continue stirring until melted, 30 to 60 seconds.
- Pour cheese sauce over the potatoes, and cover the dish with aluminum foil.
- Bake in the preheated oven until potatoes are tender and sauce is bubbly, about 1 ½ hours.
