Sage and Toasted Walnut Pesto Mashed Potatoes

What can I say, these are extremely tasty and full of sage goodness!


It is officially fall and it’s time for comfort food!  Regular mashed potatoes are a perfect side dish to a fall inspired dinner, but adding the sage pesto to them gives it an extra kick.  It is exceptionally great with my shiitake mushroom gravy and some petite peas.


Enjoy them with a nice glass of Rose wine, Albariño, Chenin Blanc or a Verdelho.

  •  1 Cups Fresh Sage
  • 3/4 Cup Toasted Walnuts
  • 1/2 Cup Asiago Cheese
  • 1/4 Cup + 2 Tablespoons Toasted Walnut Oil or to taste
  • 1 Small Cloves Garlic
  • 1 Tablespoons Fresh Lemon Juice
  • 1/4 Teaspoons Sea Salt or to taste

Start by cutting potatoes into cubes, place potatoes in a large saucepan and cover with filtered water.  Bring to a boil and cook for about 20-25 minutes or until very tender.  Use a timer and check at 15 minutes

While potatoes are cooking, make the pesto.


Preheat oven to 375°F and spread out the walnuts on a baking sheet.

Roast walnuts until they start to brown and smell toasted about 7 to 10 minutes.

Make sure and check them frequently so they don’t burn.  Cool completely

 While walnuts are toasting, shred the cheese and pick the leaves off sage stems then measure and add them to a food processor or blender along with cheese, oil, garlic, lemon juice and salt.

When walnuts are completely cool add and puree until desired texture.

The rest

When potatoes are ready, drain in a colander.

In a bowl, add potatoes and butter then mash well.  When the butter is all the way melted add the milk, salt and pepper.  Beat until fluffy.  You can either stir the pesto in completely, swirl it on top of individual servings or let your guest add their own amount.

*Option: Serve with shiitake mushroom gravy and peas.
