Description

Recipe by: Life As A Strawberry

This simple vegetarian mashed potatoes and mushroom gravy recipe gets a flavorful boost from a splash of Guinness.

Ingredients

Mashed Potatoes

  • 2 lbs. white potatoes, quartered (cut potatoes into even-sized pieces so they cook evenly!)
  • 4 Tablespoons unsalted butter
  • 1/2 cup milk
  • 1.5 cups shredded sharp white cheddar cheese
  • Salt and pepper to taste

Gravy

  • 2 Tablespoons unsalted butter
  • 10 oz. baby Portobello mushrooms, sliced
  • Salt and pepper to taste
  • 1 teaspoon soy sauce
  • 2 Tablespoons flour
  • 2/3 cup stout (I used Guinness)
  • 2/3 cup vegetable stock
  • 2 Tablespoons chopped fresh parsley (optional, for garnish)

Preparation
Prep Time: 15min | Cook Time: 30min

Mashed Potatoes:

  1. Cook potatoes in salted, boiling water until easily pierced with a fork. (Prepare the gravy while the potatoes cook if you like). Drain cooked potatoes and set aside, then return empty pot to the stove over low heat.
  2. Add butter and milk to pot and warm until butter is melted.
  3. Return potatoes to pot and mash.
  4. Add shredded cheese, salt, and pepper to mashed potatoes. Stir until cheese has melted, then taste and add seasoning as necessary.

Gravy (Make this while the potatoes cook!):

  1. Melt butter in a large skillet over medium-high heat.
  2. Add mushrooms to skillet and cook, stirring occasionally, until mushrooms have reduced in size by about half.
  3. Add soy sauce, salt, and pepper and stir to combine.
  4. Add flour and stir to combine. Let cook 30 seconds or so until liquid has been absorbed.
  5. Add stout a little at a time, stirring constantly to break up any lumps of flour.
  6. Add stock and stir to combine. Bring to a low simmer and let cook, stirring occasionally, until gravy has thickened to desired consistency. You can let the gravy simmer on low heat until the potatoes are ready!

Assemble:

  1. Top the mashed potatoes with gravy and chopped parsley (optional) and serve immediately.

Notes

  • Good quality vegetable stock is a must here – use homemade if you have it, or look for an especially tasty low-sodium variety at the store!
  • Use beef stock or chicken/turkey stock in place of the vegetable stock if you like. You can omit the soy sauce if you use beef stock.
  • If the mushrooms look too dry before you add the flour, you can add an extra pat of butter to the pan.
