The Ultimate Classic Shepherd's Pie - also known as Shepherd's Pie or Cottage Pie. Features ground beef (or lamb) and vegetables in a savory gravy, crowned with cheesy mashed potatoes and baked to perfection.
Heat the olive oil in a large skillet over medium-high heat for about 2 minutes. Add the chopped onions and cook for about 5 minutes, stirring occasionally, until softened.
Place the cubed potatoes in a large pot and cover with water. Bring the water to a boil, then reduce to a simmer. Cook until the potatoes are tender and easily pierced with a fork, about 10-15 minutes.
Spread the meat mixture evenly in a 9x9 (or 7x11) inch baking dish. Layer the mashed potatoes on top, smoothing them out to cover the meat evenly.
