Ingredients

• 4 large Russet potatoes
• 2 medium Leeks
• 8 slices Bacon
• 2 cups Cheddar cheese
• 3 tablespoons Butter
• 3 tablespoons All-purpose flour
• 2 cups Milk
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.25 teaspoon Nutmeg (optional)
• 1 teaspoon Olive oil

Directions

Step 1

Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish.

Step 2

Wash, peel, and thinly slice the potatoes into 1/8-inch thick rounds. Set aside.

Step 3

Trim the ends off the leeks, halve them lengthwise, and rinse thoroughly to remove any dirt. Slice them into 1/4-inch half-moons.

Step 4

In a large skillet, heat 1 teaspoon of olive oil over medium heat. Add the bacon slices and cook until crisp, about 8 minutes. Remove the bacon and set aside on a paper towel-lined plate. Once cooled, crumble into small pieces.

Step 5

In the same skillet, add the sliced leeks and cook over medium heat for 4-5 minutes, or until softened. Set aside.

Step 6

In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1 minute, stirring constantly, to form a roux.

Step 7

Gradually whisk in the milk, ensuring no lumps form. Cook the mixture for 3-4 minutes, or until thickened. Season with salt, black pepper, and nutmeg (if used).

Step 8

Remove the saucepan from heat and stir in 1 1/2 cups of shredded cheddar cheese, reserving 1/2 cup for topping.

Step 9

Layer half of the sliced potatoes evenly in the prepared baking dish. Top with half of the cooked leeks and half of the crumbled bacon. Pour half of the cheese sauce over this layer.

Step 10

Repeat the layers with the remaining potatoes, leeks, bacon, and cheese sauce.

Step 11

Sprinkle the reserved 1/2 cup of cheddar cheese over the top.

Step 12

Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes.

Step 13

Remove the foil and bake for another 20 minutes, or until the top is golden and bubbly, and the potatoes are fork-tender.

Step 14

Let the casserole rest for 5-10 minutes before serving. Enjoy your Leek Potato and Bacon Casserole!
