Lobster Mashed Potatoes are velvety smooth with lumps of lobster, drizzled with melted butter and topped with fresh snipped chives. Simple enough to serve on a weekday, special enough for filet or prime rib.

Lobster Mashed Potatoes

Back when I was doing publicity for my cookbook, I visited Pennsylvania while preparing for my QVC segment. Both times I stayed at the same hotel and both times I ordered filet, lobster mashed potatoes and grilled asparagus with an over-priced glass of Malbec. I still dream about that meal, but mostly I miss those mashed potatoes.

Lobster Mashed Potatoes

It’s been 3 years since I was last in Pennsylvania and it’s 3 year far too long since I had lobster mashed potatoes. So you know I had to make them and I’ll be making them again on New Years Eve.

Lobster Mashed Potatoes ingredients

To make this Lobster Mashed Potatoes you will need:

  • russet potatoes
  • unsalted butter
  • half & half
  • kosher salt
  • white pepper
  • lobster
  • melted salted butter
  • chives

wash russet potatoes or use Yukon Golds

First, scrub 3 pounds russet potatoes well. I’ve recently turned to boiling my potatoes whole with the skin on, for a couple of reasons actually. First, my pot is less of a starchy mess afterwards. And because I’ve found that boiling potatoes whole, with the skin on takes just as much time as is does to peel, chop and boil peeled potatoes.

Once the potatoes are fully cooked and can easily be pierced by a fork, I drain them and allow them to cool until safe to handle. Then I peel off the skin.

add potatoes to a pot with cool water

Place the potatoes into a large stock pot, cover with water by 2-inches, cover and bring to a boil. Reduce the heat to low and simmer until a fork pierces easily. About 30 to 40 minutes total.

lobster meat in a bowl

Meanwhile, as far as lobster goes, I purchased frozen lobster meat and simply thawed it (in the package) in a colander under cool water. Feel free to boil your own lobster, but I couldn’t get my hands on any fresh lobster at 7 in the morning when I was at the grocery store. However, there was uncooked lobster tails, but I didn’t want just tail meat either. So you do you.

With that said, this is 8 ounces of cooked lobster, claws, tail etc. coarsely diced. Refrigerate until ready to use.
