Ingredients

6
  • 2 lbs ground beef or lamb
  • 1 onion, diced
  • 2 carrots, diced
  • 2 cloves garlic, minced
  • 1 cup frozen peas
  • 2 tablespoons tomato paste
  • 1 tablespoon Worcestershire sauce
  • 1 cup beef broth
  • 2 lbs potatoes, peeled and cubed
  • 1/2 cup milk
  • 4 tablespoons butter
  • Salt and pepper to taste
  • 1 teaspoon dried thyme
  • 1 teaspoon dried rosemary

Instructions

1

Preheat your oven to 400°F (200°C).

2

In a large skillet, brown the ground meat over medium heat, breaking it apart as it cooks.

3

Add the diced onions, carrots, and garlic to the skillet. Cook until the vegetables are tender.

4

Stir in the tomato paste, Worcestershire sauce, thyme, rosemary, and beef broth. Simmer for about 5-10 minutes until thickened.

5

Meanwhile, boil the potatoes in salted water until tender, about 15 minutes. Drain and return to the pot.

6

Add milk and butter to the potatoes, and mash until smooth. Season with salt and pepper.

7

Spread the meat mixture in a casserole dish. Top with the mashed potatoes, smoothing it out.

8

Bake in the oven for 25-30 minutes, or until the top is lightly golden.

9

Let cool for a few minutes before serving.

Chef's Tips

For a creamier texture, add sour cream to the mashed potatoes.
Feel free to use leftover holiday ham in place of beef or lamb.
Let the casserole sit before serving to allow flavors to meld.

Troubleshooting

If the mashed potatoes are too dry, add more milk or butter.
Should the filling be too watery, let it simmer longer to reduce.

Recipe Variations

Top with cheese before baking for an extra layer of flavor.
Experiment by adding different vegetables such as corn or bell peppers.
Make a vegetarian version using lentils and mushrooms instead of meat.

Healthy Alternatives

Use ground turkey or chicken for a lighter option.
Replace traditional potatoes with cauliflower for a low-carb version.
Choose low-fat milk or a dairy-free alternative.

Serving Suggestions

Serve with a side of crusty bread.
Pair with a fresh green salad for balance.
Offer a pint of Irish stout to enhance the theme.
