Ingredients

For the beef layer:

  • 1 lb ground beef
  • 1 small onion, diced
  • 2 cloves garlic, minced
  • 2 tbsp tomato paste or ketchup
  • 1 tbsp Worcestershire sauce
  • 1 cup frozen peas and carrots (or mixed vegetables)
  • Salt and pepper, to taste
  • 1 tbsp oil (for sautéing)

For the mashed potatoes:

  • 3 cups mashed potatoes (fresh or leftover)
  • 2 tbsp butter
  • 1/4 cup milk or cream (more as needed for texture)
  • Salt, to taste

For topping:

  • 1 cups shredded cheddar cheese
  • Fresh parsley, chopped (optional, for garnish)

Instructions

  1. Preheat oven to 375°F and grease a 9×13-inch baking dish.
  2. In a skillet over medium heat, sauté onion in oil until soft. Add garlic and cook for 1 minute.
  3. Add ground beef and cook until browned, breaking it up as it cooks. Drain excess grease.
  4. Stir in tomato paste, Worcestershire sauce, frozen veggies, salt, and pepper. Cook for 3–4 minutes.
  5. Spread the beef mixture evenly into the prepared baking dish.
  6. In a separate bowl, mix mashed potatoes with butter and milk until smooth and creamy.
  7. Spread mashed potatoes over the beef layer, smoothing with a spatula.
  8. Top with shredded cheddar cheese.
  9. Bake uncovered for 20–25 minutes, until cheese is melted and bubbly.
  10. Let rest for a few minutes, then garnish with chopped parsley before serving.

Notes

  • Swap ground beef with ground turkey, chicken, or a beef-sausage blend.
  • Add diced jalapeños or pepper jack for a spicy twist.
  • Mix cream cheese into the potatoes for added richness.
  • Use sweet potatoes for a creative variation.
  • To achieve golden peaks, use a fork to create texture in the mashed potatoes before baking.
