Ingredients

  • 5 sausages, cooked according to package directions

Mashed Potatoes

  • 2 lb yellow potatoes, peeled and quartered
  • 4 tbsp butter, unsalted
  • ½ cup milk or heavy cream
  • salt and pepper, to taste

Onion Gravy

  • 4 tbsp butter, unsalted
  • 1 large onion, sliced
  • 2 tbsp brown sugar
  • 4 tbsp all-purpose flour
  • ¼ cup red wine
  • 1 tsp dried thyme (or 1 tbsp fresh)
  • 2 cups beef broth
  • 1 tbsp Worcestershire sauce
  • 1 tbsp Dijon mustard
  • ¼ tsp black pepper
  • 1 tsp salt
  • 1 tbsp balsamic vinegar

Instructions

Mashed Potatoes:

  • Place the peeled and quartered potatoes in a large pot covered with cold, salted water.
  • Bring to a boil and cook for about 15 minutes or until the potatoes are fork-tender. Drain well.
  • Return the potatoes to the pot, add the butter and milk or heavy cream, and mash them until soft and fluffy.
  • Add salt and pepper to taste. Set aside and cover to keep warm.

Onion Gravy:

  • In a cast-iron skillet, melt the butter over medium-low heat. Add the sliced onions and brown sugar and cook for about 30 minutes, stirring every few minutes.
  • Add the flour and stir to coat the onions, cook for a few minutes, stirring constantly.
  • Add the red wine and herbs and bring to a boil. Scrape along the bottom of the pan to remove any stuck, browned bits. Reduce the heat to a simmer and cook for about 5 minutes.
  • Add the beef broth, Worcestershire sauce, dijon mustard, salt, pepper, and balsamic vinegar, and bring to a boil. Reduce the heat to a low simmer and cover. Cook for about 10-15 minutes or until thickened, stirring occasionally.
  • To serve, place hot mashed potatoes on a plate, top with cooked sausages and pour onion gravy over the top.

Notes

  • Choose high-quality pork sausages: Bratwurst or British-style sausages like Cumberland or Lincolnshire are perfect for this recipe. Always opt for uncooked sausages.
