Ingredients

• 3 lbs Russet potatoes
• 6 tbsp Unsalted butter
• 1 cup Whole milk
• 1 cup Buttermilk
• 1.5 cups Asiago cheese, shredded
• 2 tbsp Fresh chives, chopped
• 2 tsp Salt
• 1 tsp Ground black pepper
• 2 cloves Garlic, minced
• 0.5 cup Breadcrumbs
• 1 tbsp Olive oil

Directions

Step 1

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with butter or non-stick spray.

Step 2

Peel and chop the russet potatoes into evenly sized chunks. Place them in a large pot and cover with cold, salted water.

Step 3

Bring the pot of potatoes to a boil over high heat, then reduce the heat to medium and simmer for 15-20 minutes, or until the potatoes are fork-tender.

Step 4

Drain the cooked potatoes and return them to the pot. Turn on low heat for 1-2 minutes to evaporate any residual moisture.

Step 5

Add the butter, milk, buttermilk, minced garlic, salt, and pepper to the potatoes. Mash the mixture until smooth and creamy. Adjust seasoning to taste.

Step 6

Stir in 1 cup of shredded Asiago cheese and the chopped chives, reserving the remaining 0.5 cup of cheese for later.

Step 7

Transfer the mashed potatoes to the prepared baking dish, spreading evenly into a smooth layer.

Step 8

Sprinkle the reserved Asiago cheese evenly over the top of the mashed potatoes.

Step 9

In a small bowl, mix the breadcrumbs with the olive oil. Sprinkle the breadcrumb mixture evenly over the cheese layer.

Step 10

Bake in the preheated oven for 25-30 minutes, or until the top is golden and bubbling.

Step 11

Allow the gratin to cool for 5-10 minutes before serving. Garnish with additional chives if desired and enjoy!
