Ingredients

• 6 medium-sized Russet potatoes
• 4 tablespoons Unsalted butter
• 4 tablespoons All-purpose flour
• 2 cups Whole milk
• 1 cup Heavy cream
• 2 cups Shredded cheddar cheese
• 1 cup Shredded Parmesan cheese
• 1 teaspoon Garlic powder
• 1 teaspoon Onion powder
• 1 teaspoon Salt
• 0.5 teaspoons Black pepper
• 2 tablespoons Fresh parsley, chopped (optional for garnish)
• 1 as needed Cooking spray

Directions

Step 1

Peel the Russet potatoes and slice them into 1/8-inch thin rounds using a knife or mandoline slicer. Rinse the slices under cold water and pat them dry.

Step 2

In a medium-sized saucepan, melt the butter over medium heat. Once melted, whisk in the flour and cook for 1-2 minutes to form a roux.

Step 3

Gradually add the milk and heavy cream to the roux, whisking constantly to prevent lumps. Cook until the sauce thickens, about 3-4 minutes.

Step 4

Stir in the shredded cheddar cheese, Parmesan cheese, garlic powder, onion powder, salt, and black pepper. Continue stirring until the cheese is fully melted and the sauce is smooth. Remove from heat.

Step 5

Spray the inside of your crockpot with cooking spray to prevent sticking.

Step 6

Layer the potato slices evenly in the crockpot, slightly overlapping each layer.

Step 7

Pour a portion of the cheese sauce over the potato layer, spreading it evenly to coat. Repeat this process layering potatoes and cheese sauce until all the ingredients are used, finishing with a layer of cheese sauce on top.

Step 8

Cover the crockpot with its lid and set it to cook on HIGH for 4 hours or LOW for 6-7 hours, until the potatoes are fork-tender.

Step 9

If desired, transfer the cooked potatoes to an oven-safe dish, top with additional cheese, and broil for 2-3 minutes to create a golden, crispy topping.

Step 10

Garnish with freshly chopped parsley before serving. Enjoy your creamy au gratin potatoes!
