Baked Mashed Potatoes with Parmesan

These baked mashed potatoes are fluffy, rich, and creamy with a delicious golden brown cheesy parmesan topping.

They make the perfect side dish for special occasions, holidays, or dinner parties.

Mashed potatoes are a delicious side for any comfort meal.

What makes these mashed potatoes special is that they combine butter, grated parmesan, heavy cream, sour cream, and green onions.

Then they are baked in the oven to form a buttery, golden brown parmesan crust.

The texture and flavor combination is incredible.

The result is the BEST MASHED POTATOES ever!!!

Try them to see why they are my personal favorite way to eat mashed potatoes.

Ingredients

You will need the following ingredients for baked mashed potatoes:

• shredded parmesan- I like the shredded parmesan mixed in the mashed potatoes because of the texture it creates when it melts into the potatoes.
• grated parmesan- The grated parmesan makes the perfect texture for the crust topping.
• Russet potatoes- I use Russet potatoes in this recipe for the high starch content. They whip up fluffy and light. A great substitute is the Yukon Gold potato.
• sour cream
• butter
• heavy cream-You can substitute with whole milk.
• green onions- The green onions add a nice flavor without overpowering the potatoes. You can substitute with chives or omit.

Note

Note: I like using both the shredded parmesan and grated parmesan in this recipe. Shredded parmesan contains moisture and the cheesy strands melts slower creating a rich, fluffy, binding texture. The grated parmesan is dry and melts fast creating a crispy beautiful crust. For optimal results, use both cheeses. If you only want to use one type of parmesan, I would use the grated because the crust really makes this dish special.
