A comforting and easy shepherd’s pie casserole with layers of seasoned ground meat, mixed vegetables, and fluffy mashed potatoes. Perfect for a hearty weeknight dinner.

Ingredients

  • 1 lb ground beef or ground lamb
  • 1 small onion, chopped
  • 2 cloves garlic, minced
  • 1 1/2 cups mixed frozen vegetables (peas, carrots, corn, green beans)
  • 2 tbsp tomato paste
  • 1 tbsp Worcestershire sauce
  • 1/4 cup beef broth
  • 2 cups mashed potatoes (fresh or leftover)
  • 1 tbsp olive oil or butter
  • Salt and pepper to taste
  • Optional: 1/2 cup shredded cheese for topping
  • Optional: fresh herbs like parsley or thyme

Instructions

  1. Preheat the oven to 400°F (200°C).
  2. In a skillet, cook the ground beef or lamb over medium heat until browned, then drain excess fat if needed.
  3. Add chopped onion and garlic, cooking until softened.
  4. Stir in tomato paste, Worcestershire sauce, and beef broth; simmer for a few minutes.
  5. Add the mixed vegetables and season with salt and pepper, then transfer the meat mixture to a greased casserole dish.
  6. Spread mashed potatoes evenly on top, smoothing or using a fork to create texture.
  7. Optional: sprinkle shredded cheese on top.
  8. Bake for 20–25 minutes, until the top is lightly browned and the casserole is heated through.
  9. Let cool slightly before serving.

Notes

  • Add cooked mushrooms to the meat for extra depth.
  • Use ground turkey or chicken for a lighter version.
  • For a dairy-free option, use olive oil in mashed potatoes and skip cheese.
  • For a low-carb version, use mashed cauliflower instead of potatoes.
  • Leftovers store in the fridge for up to 4 days and reheat in the microwave or oven.
  • Can be frozen unbaked and baked when ready.
