Ingredients
Method
- Cover the cubed potatoes with cold salted water and boil over high heat, then simmer for 15 to 18 minutes until fork-tender.
- Mix the ground beef with garlic powder, onion powder, salt, and pepper. Form into 4 thin patties and sear in hot vegetable oil over medium-high heat for 3 to 4 minutes per side until deeply browned. Set aside.
- In the same skillet over medium heat, melt the butter and cook the mushrooms and onions for 10 to 12 minutes until soft and golden.
- Stir in the flour for 1 minute, then add the beef broth and Worcestershire sauce. Simmer for 4 to 5 minutes until the gravy coats the back of a spoon. Return the patties to the skillet and simmer for 2 more minutes.
- Drain the potatoes and mash with butter, sour cream, warmed milk, and salt until smooth.
- Spoon mashed potatoes onto each plate, top with a patty, and ladle mushrooms, onions, and gravy over everything. Garnish with chopped chives.
Notes
The gravy will thicken as it sits, so if you're plating over a few minutes, keep it on the lowest heat setting and give it a stir. You can make the mash up to 30 minutes ahead and keep it covered over very low heat; just stir in a small splash of warm milk right before serving to freshen the texture.
