Ingredients
Scale
Meat and Vegetables
- 1 lb ground lamb (or ground beef)
- 3 cups mirepoix (onion, carrot, celery), diced
- Fresh herbs (rosemary and thyme), chopped, about 1 tablespoon each
- Salt and pepper, to taste
- 1 clove garlic, minced
- ¾ cup peas
Potatoes and Dairy
- 2 lbs Yukon gold potatoes, peeled and chopped
- 4 ounces Irish cheddar cheese, shredded
- ¾ cup half and half
Other Seasonings and Sauces
- 1 tablespoon Worcestershire sauce
- 1 tablespoon tomato paste
- 1 cup beef or vegetable stock
Instructions
- Prepare the potatoes: Peel and chop the Yukon gold potatoes. Place them in a pot of salted water and bring to a boil. Cook until fork-tender, about 15-20 minutes. Drain thoroughly, then mash them with the shredded Irish cheddar cheese and half and half until creamy and smooth. Set aside.
- Brown the meat: In a large oven-safe pot or Dutch oven, heat over medium heat. Add the ground lamb or beef and cook, stirring and breaking apart, until browned and cooked through, about 8-10 minutes. Drain off excess fat.
- Sauté the mirepoix and garlic: Add the diced onion, carrot, and celery (mirepoix) to the browned meat. Sauté until vegetables are soft and translucent, about 5-7 minutes. Stir in minced garlic and cook for another 1 minute until fragrant.
- Add seasonings and simmer: Stir in tomato paste, Worcestershire sauce, fresh rosemary and thyme, and pour in the stock. Bring the mixture to a simmer and cook gently uncovered for 15 minutes to develop flavors and slightly reduce the liquid.
- Finish the filling: Stir in the peas and season the meat mixture with salt and pepper to taste. Spread the savory filling evenly in the pot or transfer to a baking dish if desired.
- Top with cheesy mashed potatoes: Evenly spoon and spread the cheesy mashed potatoes over the meat filling, smoothing the surface to cover completely.
- Bake and broil: Place the pot or baking dish in a preheated oven at 425°F (220°C). Bake for 15 minutes or until the pie is heated through and the top is bubbling. For a golden, slightly crisp finish, broil on high for 2-3 minutes while watching carefully to avoid burning.
Notes
- You can substitute ground beef for lamb if preferred for a milder flavor.
- Use a large oven-safe pot to finish cooking and baking in the same vessel for ease and less cleanup.
- If you want a thicker filling, reduce the stock slightly or add a tablespoon of flour before simmering.
- Broiling at the end is optional but recommended for a beautiful golden top.
- Fresh herbs can be adjusted according to taste; rosemary and thyme complement lamb well.
