Ingredients

Scale
  • 1.5 lbs Russet potatoes, peeled and quartered
  • 4 tablespoons unsalted butter
  • 1/2 cup whole milk, warmed
  • 1/4 cup heavy cream
  • Salt and black pepper to taste
  • 8 high-quality pork sausages (Bangers)
  • 1 tablespoon olive oil
  • 2 large yellow onions, thinly sliced
  • 2 cloves garlic, minced
  • 1/4 cup all-purpose flour
  • 1 cup beef broth
  • 1/2 cup dry red wine or stout beer
  • 1 teaspoon fresh thyme leaves
  • 1 teaspoon Worcestershire sauce

Instructions

  1. Place the potatoes in a large pot and cover with cold, salted water. Bring to a boil and cook until fork-tender, about 15 to 20 minutes.
  2. While potatoes cook, prepare the gravy. Heat olive oil in a large skillet over medium heat. Add the sliced onions and cook slowly, stirring occasionally, for 15 to 20 minutes until deeply caramelized and soft. Add the minced garlic and cook for 1 minute more until fragrant.
  3. Sprinkle the flour over the onions and stir constantly for 1 minute to cook out the raw flour taste. Slowly whisk in the beef broth and red wine or stout, scraping up any browned bits from the bottom of the pan.
  4. Stir in the thyme and Worcestershire sauce. Bring the gravy to a simmer and cook until it thickens enough to coat the back of a spoon, about 5 to 8 minutes. Reduce heat to low to keep warm.
  5. Drain the cooked potatoes well and return them to the hot pot. Mash thoroughly. Add the butter, warm milk, and heavy cream. Whip until the mashed potatoes are smooth and creamy. Season generously with salt and pepper.
  6. Cook the sausages. Heat a large skillet over medium heat. Add the sausages and cook, turning often, until they are browned on all sides and cooked through, about 12 to 15 minutes.
  7. To serve, place a generous portion of creamy mashed potatoes on each plate. Arrange two sausages on top of the mash. Spoon the rich onion gravy liberally over the sausages and potatoes.

Notes

  • For the creamiest mash, use a potato ricer instead of a standard masher.
  • If you prefer a slightly sweeter gravy, substitute balsamic vinegar for a portion of the red wine.
  • Ensure your sausages are high quality, as they are the star of this dish.
