Easy Shepherd’s Pie Casserole

A comforting and easy-to-make shepherd’s pie casserole featuring a savory ground beef filling topped with creamy mashed potatoes, baked until golden and bubbly.

Ingredients

Scale
  • 1 pound ground beef
  • 1 medium onion, chopped
  • 2 cloves garlic, minced
  • 1 cup frozen mixed vegetables (peas, carrots, corn)
  • 2 tablespoons tomato paste
  • 1 cup beef broth
  • 1 teaspoon Worcestershire sauce
  • Salt and pepper to taste
  • 3 cups mashed potatoes (prepared from about 3 large potatoes)
  • 2 tablespoons butter
  • 1/4 cup shredded cheddar cheese (optional)

Instructions

  1. Preheat oven to 400°F (200°C).
  2. In a large skillet, cook ground beef over medium heat until browned; drain excess fat.
  3. Add chopped onion and minced garlic to the skillet; cook until softened, about 3-4 minutes.
  4. Stir in frozen mixed vegetables, tomato paste, beef broth, Worcestershire sauce, salt, and pepper.
  5. Simmer the mixture for 5-7 minutes until slightly thickened.
  6. Transfer the beef mixture to a casserole dish, spreading evenly.
  7. Top with prepared mashed potatoes, spreading to cover the filling completely.
  8. Dot the mashed potatoes with butter and sprinkle with shredded cheddar cheese if using.
  9. Bake in the preheated oven for 20-30 minutes until the top is golden and bubbly.
  10. Let cool for 5 minutes before serving.

Notes

For extra flavor, use homemade mashed potatoes with cream and butter. You can substitute ground lamb for beef to make a traditional shepherd’s pie. Leftovers reheat well and make great next-day meals.
