Ingredients

• 4 large Russet potatoes
• 6 tablespoons Unsalted butter
• 0.5 cup Heavy cream
• 1.5 cups Parmesan cheese
• 1 cup Sharp cheddar cheese
• 3 large Egg yolks
• 2 cloves Garlic
• 1 teaspoon Fresh thyme
• 2 teaspoons Salt
• 0.5 teaspoon Black pepper
• 0.25 teaspoon Nutmeg
• 1 cup Whole milk
• 0.5 cup Panko breadcrumbs
• 1 teaspoon Olive oil
• 1 tablespoon Parsley (optional, for garnish)

Directions

Step 1

Peel the russet potatoes and cut them into large chunks.

Step 2

Place the potatoes in a large pot, cover with water, and add a pinch of salt. Bring to a boil and cook until fork-tender, about 15-20 minutes.

Step 3

Drain the potatoes thoroughly and return them to the pot. Mash until smooth.

Step 4

To the mashed potatoes, mix in 4 tablespoons of butter, 0.5 cups of heavy cream, 0.75 cups of Parmesan cheese, salt, pepper, and nutmeg. Taste and adjust seasoning.

Step 5

Once slightly cooled, fold in the egg yolks until fully incorporated. Transfer the potato mixture into a piping bag fitted with a star or round tip.

Step 6

In a medium saucepan, melt the remaining 2 tablespoons of butter over medium heat. Add minced garlic and thyme, cooking until fragrant, about 1 minute.

Step 7

Stir in the 1 cup of milk and 0.5 cups of heavy cream. Gradually whisk in 0.75 cups of Parmesan and 1 cup of cheddar cheese until smooth and melted.

Step 8

Preheat the oven to 375°F (190°C) and grease a casserole or baking dish.

Step 9

Spread a thin layer of the cheese sauce on the bottom of the dish. Pipe the mashed potatoes in decorative swirls or layers over the sauce.

Step 10

Pour the remaining cheese sauce over the potatoes, ensuring everything is evenly coated.

Step 11

In a small bowl, mix panko breadcrumbs with 1 teaspoon of olive oil. Sprinkle the breadcrumbs over the casserole evenly to create a crisp topping.

Step 12

Bake the dish for 25-30 minutes or until the top is golden and bubbling.

Step 13

Let cool for a few minutes, garnish with parsley if desired, and serve warm.
