Vegan Chive & Garlic Duchess Potatoes

Sometimes I have a recipe idea that floats around my head for what feels like forever before it finally ends up on the blog. This is one of those recipes. Duchess potatoes were a classic we made back when we were A.) vegetarian but not vegan, and B.) in cook’s training back in BC. Duchess potatoes are like mashed potatoes’ fancier, snobbish older sister.  Except they have good reason for it, because they’re really seriously delicious.

Typically, duchess potatoes are little piped mountains of mashed potatoes made with egg (to stabilize them), brushed with melted butter and baked until crispy and golden brown. This delicious vegan version is every bit as golden-brown, crispy, savoury and amazingly tasty as their non-vegan counterparts.

These crispy mashed swirls get an extra kick of flavour from garlic and chives. I used cashew cream (soaked raw cashews + Silk Unsweetened Almondmilk) and a touch of cornstarch to make them fluffy yet stable. These potatoes hold their shape almost perfectly in the oven! They’ll lose a bit of height during cooking so maker sure to pipe ’em nice and tall if you want proper “mountains”.

All in all, this recipe is pretty foolproof. I do have a couple of tips though.

First, as much as I love the added nutrition and texture of leaving the skins in my mashed potatoes, this is not the time or the place for potato skins. They’ll clog up your piping tip and make the piping part an absolute nightmare.

Second, use a very large star tip (cake decorating tips should work well) if you have one.

Third, if you don’t want to bother with piping these little guys, you can just cut off the end of a large ziploc bag and use that or simply dollop mountains of mashed potatoes on a baking sheet and rough up the tops with a fork. The more little nooks and crannies you can get out of your piping tip or fork, the crispier and more delicious your potatoes will be!

I wanted to keep this recipe as simple as possible so I made the duchess potatoes all by themselves. I think they’d be completely out-of-this-world delicious with some mushroom gravy. They’d be perfect for Thanksgiving or Christmas dinner!

Ingredients :

  • 4 ½ cups chopped and peeled russet potatoes (1 ½ lbs or 685g – approx. 2 large baking russets)
  • 1 cup raw cashews, soaked in HOT water for a minimum of 30 minutes
  • ½ cup
  • 2 tsp cornstarch
  • 2 1/2 tbsp vegan butter, divided
  • 1 clove garlic, minced
  • 4 tbsp finely chopped fresh chives, divided
  • 1 tsp salt
  • Black pepper, to taste

Instructions :

  1. Preheat oven to 400F.
  2. Heat a large pot of water over high heat. Add chopped russet potatoes and wait for the water to boil. Once water is boiling, cook potatoes for 6 minutes or until potatoes are fork tender. Once potatoes are finished cooking, drain and transfer them to a bowl.
  3. While you wait for the potatoes to cook, combine soaked or boiled cashews with Silk Unsweetened Almond milk and 2 tsp cornstarch. Blend on high until smooth and creamy.
  4. In a small microwave-safe bowl combine minced garlic and 1 1/2 tbsp vegan butter. Microwave for 1 minute or until vegan butter is melted and garlic is fragrant.
  5. Add the creamed cashews, garlic butter, 2 tbsp chives, salt and pepper to the potatoes. Mash using a potato ricer or a mashed potato immersion blender attachment. The mashed potatoes must be smooth and lump-free. Taste and adjust salt and pepper if necessary.
  6. Spoon mashed potatoes into a piping bag with a large star tip. Pipe swirly mashed potato mountains onto a lightly greased baking sheet.
  7. In microwave, melt 1 tbsp vegan butter. Lightly brush (more like dabbing, be gentle!) melted vegan butter over the potatoes.
  8. Bake for 40 minutes or until the tops are slightly browned and bottoms are crisp. If necessary, turn on broiler and broil for 1-5 minutes or until most of the piped edges are golden and crisp.
  9. Garnish with cracked black pepper and 2 tbsp chives.
