Ingredients

• 4 medium-sized Russet potatoes
• 3 tablespoons Unsalted butter
• 2 tablespoons All-purpose flour
• 2 cups Milk
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.5 teaspoon Garlic powder
• 1.5 cups Cheddar cheese, shredded
• 0.5 medium Onion, thinly sliced (optional)
• 1 tablespoon Parsley (optional, for garnish)

Directions

Step 1

Peel and thinly slice the potatoes into even 1/8-inch thick slices. If using onion, thinly slice it as well.

Step 2

In a microwave-safe dish, melt the butter on high power for 30 seconds to 1 minute or until fully melted.

Step 3

Whisk the flour into the melted butter until smooth, creating a roux.

Step 4

Gradually whisk in the milk, ensuring no lumps form. Add salt, black pepper, and garlic powder. Microwave the mixture on high power in 1-minute intervals, whisking after each interval, until thickened (about 3 minutes total).

Step 5

Stir in 1 cup of the shredded cheddar cheese until melted and completely incorporated into the sauce.

Step 6

Arrange a layer of potato slices at the bottom of a large microwave-safe dish (about 2-quart capacity). If using onions, scatter a few slices over the potatoes.

Step 7

Pour a portion of the cheese sauce over the potato layer. Repeat this layering process, alternating potatoes, onion (if using), and cheese sauce, until all ingredients are used. Ensure the top layer is covered with cheese sauce.

Step 8

Sprinkle the remaining 0.5 cups of shredded cheddar cheese evenly over the top layer.

Step 9

Cover the dish with a microwave-safe lid or plastic wrap. Poke a few small holes in the plastic wrap for ventilation.

Step 10

Microwave the dish on 70% power for 15–20 minutes, or until the potatoes are tender when pierced with a fork. Check halfway through the cooking process and rotate the dish if necessary to ensure even cooking.

Step 11

Carefully remove the dish from the microwave (it will be hot) and let it sit for 5 minutes to allow the sauce to thicken further.

Step 12

Garnish with parsley, if desired, and serve warm.
