Authentic Irish Shepherds Pie
Authentic Irish Shepherd’s Pie is a cozy bake of ground lamb simmered in a savory gravy with onions (often with carrots/peas), topped with fluffy mashed potatoes, then baked until bubbling with a golden top. The key “authentic” distinction is the meat: shepherd’s pie uses lamb, while cottage pie uses beef.
Dish type
Dish type: Savory casserole (meat-and-gravy base with mashed potato topping).

Cuisine: Irish/UK comfort food, often associated with Irish home cooking.
Cooking method: Simmer filling to thicken, top with mash, bake around 25–30 minutes at 400°F until browned and bubbling.

Ingredients

Step-by-Step Instructions
Cook the potatoes. Boil peeled, chopped potatoes until soft, then drain and mash with butter and milk/half-and-half, seasoning with salt and pepper. Tip: mash until smooth but don’t overwork or it can get gluey.
Brown the lamb and aromatics. Cook ground lamb with onion (and carrots if using) until browned and the vegetables soften. Tip: browning builds flavor that makes the gravy taste deeper.
Build a thick gravy. Stir in tomato paste (and flour if using), then add broth and simmer until the filling is thick and gravy-like. Tip: you want it thick enough that it won’t “soupy” the mashed potatoes on top.
Add peas and assemble. Stir peas into the filling, spread it in a baking dish, then top with mashed potatoes and rough up the surface with a fork for crisp ridges. Tip: those fork grooves brown beautifully.
Bake until golden. Bake in a 400°F oven about 25–30 minutes (or until bubbling and browned on top). Tip: if you want extra browning, finish with a quick broil, watching closely.
Rest briefly and serve. Let it sit a few minutes so slices hold together better. Tip: resting also prevents the filling from spilling out too fast.
Tips for Success
- Use lamb if you want “authentic” shepherd’s pie; beef makes it cottage pie.
- Simmer filling until thick, a watery base makes the topping sink and the pie feel loose.
- Rough up the mashed potato top with a fork for crisp edges and better browning.
Variations & Substitutions
- Cottage pie swap: substitute ground beef for lamb (still delicious, just technically cottage pie).
- Guinness-style gravy: some Irish-style versions simmer the lamb in stout for deeper flavor.
- Extra creamy topping: add parmesan or cheddar into the mash for a richer top.
What to Serve With It
- Simple green veg (peas, green beans, or cabbage) to balance the richness.
- Extra gravy on the side is a common serving style in some recipes.

Storage & Reheating
Reheat shepherd’s pie covered with foil at 350°F until heated through, about 30 minutes, to prevent the potatoes from over-browning. It also freezes well, but thawing overnight in the fridge helps it reheat more evenly.
Nutrition Facts
Nutrition depends on lamb fat percentage and how much butter/milk you use in the mash. If you tell me your lamb leanness and serving count, I can estimate calories and macros per portion.
Common Mistakes to Avoid
- Using beef and calling it shepherd’s pie (if you care about the traditional name).
- Not thickening the filling enough before baking, which can make the pie runny.
- Smoothing the mash too flat, which reduces browning, fork ridges help.
