Step 1

Mix together water and ½ teaspoon salt.

Step 2

To the electric pressure cooker, add the salt water and then sliced potatoes. Program the electric pressure cooker to cook on “manual” or “pressure cook” for 1 minute.

Step 3

Meanwhile, prepare the cheese sauce by melting the butter in a medium saucepan over medium heat. Stir in flour, remaining salt and pepper. Cook for 1 minute. Add milk all at once and continue stirring until the mixture comes to a boil. Mix in 2 cups of cheese and remove from heat. The sauce will continue to thicken as it rests.

Step 4

Preheat the oven broiler. Prepare a 9x9 square baking dish with nonstick cooking spray.

Step 5

When the electric pressure cooker cycle is complete, perform a quick pressure release. Carefully remove potatoes and layer with cheese sauce in baking dish.

Step 6

Cover the casserole with remaining cheese, if desired. Place under the broiler for 2 to 3 minutes or until the cheese has melted.
