Prep Time, Cook Time, Total Time

• Prep Time: 15 minutes
• Cook Time: 1 hour 30 minutes
• Total Time: 1 hour 45 minutes

Ingredients

• 4 russet potatoes, peeled and sliced into 1/4 inch slices (about 2 pounds)
• 1 yellow onion, sliced into rings
• 3 tablespoons unsalted butter
• 3 tablespoons all-purpose flour
• 1/2 teaspoon kosher salt
• 2 cups whole milk, room temperature
• 1 1/2 cups mild cheddar cheese, shredded
• Salt and pepper to taste

Step-by-Step Instructions

Step 1: Prepare the Baking Dish

Preheat the oven to 400°F. Lightly spray an 8×8 inch casserole dish with nonstick cooking spray to prevent sticking and ensure clean layers after baking.

Step 2: Layer the Potatoes and Onions

Arrange the potato slices and onion rings in the prepared dish, alternating between potato and onion. Make the layers as even as possible to allow consistent cooking.

Step 3: Prepare the Cheese Sauce

Melt the butter in a medium saucepan over medium heat. Whisk in the flour and salt, stirring constantly for one minute to form a smooth roux. Add the milk and cook until thickened. Stir in all the cheese at once and continue stirring until melted and smooth.

Step 4: Pour the Sauce Over the Layers

Pour the cheese sauce evenly over the potatoes and onions, allowing it to seep into the layers.

Step 5: Cover and Bake

Cover the dish with aluminum foil and bake for 85 to 90 minutes or until the potatoes are tender.

Step 6: Optional Broil Finish

For a crisp topping, switch the oven to broil and heat until the top becomes golden brown.

Pro Tips

1. Use a mandoline for uniform potato slices. Even slices cook evenly.
2. Warm milk blends faster into the roux and prevents clumps.
3. For a firmer texture, allow the dish to cool 10 minutes before serving.
