Ingredients
4 large starchy potatoes (such as Russets)
2 yellow or white onions
2 cups shredded sharp cheddar cheese
1 cup shredded mozzarella cheese
1/4 cup unsalted butter
2 tablespoons all-purpose flour
2 cups whole milk
Salt and pepper to taste
Pinch of paprika or garlic powder (optional)
Directions
Preheat your oven to 375°F (190°C) and grease a baking dish with butter or cooking spray.
Peel and thinly slice the potatoes and onions using a sharp knife or mandoline slicer.
In a skillet, melt butter over medium heat and sauté the onions until golden brown and caramelized. Set aside.
In a saucepan, melt butter and whisk in flour to create a roux. Gradually pour in milk, stirring constantly until the sauce thickens.
Remove the saucepan from heat and stir in the shredded cheese until smooth and creamy.
Layer the sliced potatoes in the prepared baking dish, seasoning each layer with salt, pepper, and a portion of the cheese sauce.
Top the casserole with the caramelized onions and an additional sprinkle of cheese.
Cover the dish with foil and bake for 45 minutes. Uncover and bake for an additional 15 minutes or until the top is golden and bubbly.
Let the casserole rest for a few minutes before serving to allow the flavors to meld together.
Enjoy the Cheese Potato Onion Casserole hot, fresh from the oven, and savor the delicious combination of flavors and textures in every bite.
