Ingredients

  • 1 lb russet or red potatoes
  • 1 tablespoon butter
  • 2 tablespoons sour cream
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 4 pork sausages I used Irish bangers
  • 1 tablespoon olive oil
  • 1 tablespoon butter
  • 1 medium yellow onion
  • 1 teaspoon minced garlic
  • 1.25 cups beef stock
  • 1 tablespoon cornstarch See note
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

Instructions

  • Start by making mashed potatoes. Use your preferred method. I use my Instant Pot Mashed Potatoes recipe. Add butter and sour cream and mash well. Season with salt and pepper.
  • Slice the onion. Measure out beef stock and whisk it with cornstarch.
  • In a skillet, heat up olive oil. Brown sausages on each side. Remove from pan.
  • Add butter to the same skillet. Add onion and garlic. Saute until fragrant and nicely brown. Add beef stock and cornstarch mixture. Simmer until thickened into a sauce. Season with salt and pepper. Add sausages back to the gravy and heat it all up together.
  • Serve sausages with gravy on a bed of mashed potatoes and a side of green peas.
