Porcini Mashed Potatoes



Serving size

about 1 cup
75 Minutes

This recipe can easily be multiplied and will keep well up to 48 hours. To reduce active cooking time, the porcini liquid can be made ahead of time (even the day before) and the reconstituted mushrooms refrigerated whole until needed. The porcini broth will freeze well for another use (such as the Mushroom Jus).

Porcini Mashed Potatoes


3 1/2 quart Water
1 ounce Mushrooms, shiitake, dried (use dried porcini if available)(dried portobellos are also an option)
1 pound Yukon gold potatoes
4 tsp. Olive oil
1/4 cup Reduced fat buttermilk
1/4 cup 2% milk
1/4 tsp. Salt
1 to taste Black pepper


Place 2 cups water in a small saucepan over high heat.

Add the dried porcini.

When the water begins to boil reduce the heat to low.

Let the mushrooms steep in the warming water for 1 hour.

Remove the broth from the heat and pour into a fine mesh strainer over a bowl.

Set the broth aside for another use (Mushroom Jus is a great recipe). The broth will freeze well.

Mince the porcini mushrooms.

While the mushrooms are steeping, place the water in a large stock pot over high heat.

Quarter the potatoes and add to the stock pot. Cover with water by about an inch. Bring to boil and then reduce heat until the water is simmering.

Cook the potatoes about 15 - 20 minutes until slightly soft in the middle. They should give when squeezed.

Remove from heat and drain water.

Add the butter, buttermilk, milk and salt.

Mash potatoes until creamy. I like to leave some chunks. If you like them smooth be careful because over mashing will result in pasty potatoes. Add the mushrooms and fold them in gently.

Add ground black pepper to taste.

Recipe Notes

This is a rich, rich, rich side dish. It is a great example of how powerful flavors in a side dish can be the star of the plate. Combine the best quality extra virgin olive oil with the porcini mushrooms and then serve the potatoes with a simple pan roasted steak or fish filet.

"I know a planet where there is a certain red-faced gentleman. He has never smelled a flower. He has never looked at a star. He has never loved any one. He has never done anything in his life but add up figures. And all day he says over and over, just like you: 'I am busy with matters of consequence!' And that makes him swell up with pride. But he is not a man - he is a mushroom!"

Antoine de Saint-Exupéry, The Little Prince
