Description

A comforting casserole layered with savory beef and vegetables under creamy mashed potatoes, perfect for weeknight dinners.


Ingredients

  • 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 the oven to 400°F (200°C).
  2. Heat a large skillet over medium. Add the ground beef and cook, breaking it up, until browned. Drain any excess fat.
  3. Add the chopped onion and minced garlic to the skillet. Cook until the onion softens, about 3–4 minutes.
  4. Stir in the frozen mixed vegetables, tomato paste, beef broth, and Worcestershire sauce. Season with salt and pepper.
  5. Bring the mixture to a simmer. Let it cook for 5–7 minutes, stirring occasionally, until slightly thickened and flavors meld.
  6. Spoon the beef and vegetable mixture into a casserole dish and spread it into an even layer.
  7. Top the filling with the prepared mashed potatoes. Use a spatula to spread them to cover the filling completely.
  8. Dot the top of the mashed potatoes with butter. Sprinkle the shredded cheddar cheese over the potatoes if you’re using it.
  9. Bake in the preheated oven for 20–30 minutes, until the top is golden and the edges are bubbly.
  10. Remove from the oven and let the casserole rest for 5 minutes before serving.

Notes

For a lighter version, use ground turkey or chicken. Instant mashed potatoes can be used in a pinch. This dish reheats well, making it great for leftovers.
