Recipe Information
Ingredients
- 3 lbs Yukon Gold potatoes
- 6 tbsp Unsalted butter
- 1.5 cups Heavy cream
- 1 cup Sour cream
- 2 cups Shredded sharp cheddar cheese
- 0.5 cups Grated Parmesan cheese
- 2 cloves Minced garlic
- 1 tsp Salt
- 0.5 tsp Ground black pepper
- 0.75 cups Breadcrumbs
- 2 tbsp Olive oil
- 0.25 cups Fresh chopped chives
Instructions
Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with cooking spray or a small amount of butter.
Peel and chop the Yukon Gold potatoes into even-sized chunks. Place them in a large pot and add enough water to cover them. Bring to a boil over medium-high heat, then reduce to a simmer. Cook for 15-20 minutes or until the potatoes are fork-tender.
Drain the potatoes and return them to the pot. Allow the potatoes to sit for a minute to let any excess moisture evaporate.
Add the butter, heavy cream, sour cream, minced garlic, salt, and black pepper to the potatoes. Mash the mixture with a potato masher or use a hand mixer until smooth and creamy.
Gently fold in 1.5 cups of shredded sharp cheddar cheese and 0.25 cups of grated Parmesan cheese until well combined. Reserve the remaining cheddar and Parmesan for the topping.
Transfer the mashed potato mixture to the prepared baking dish, spreading it out evenly.
In a small bowl, combine the breadcrumbs, olive oil, the remaining cheddar cheese, and Parmesan cheese. Stir until the breadcrumbs are moistened and the cheese is evenly mixed.
Sprinkle the breadcrumb mixture evenly over the mashed potatoes in the casserole dish.
Bake in the preheated oven for 25-30 minutes or until the topping is golden brown and crispy.
Remove from the oven and let the casserole rest for 5 minutes before serving. Garnish with freshly chopped chives for added flavor and presentation.
