Ingredients You’ll Need

Ingredient and Method appear in their dedicated parts below.

• 1 ½ lbs ground lamb (or ground beef)
• 1 medium onion, finely chopped
• 2 medium carrots, diced
• ¾ cup peas (fresh or frozen)
• 3 cups mashed potatoes (prepared with butter and milk)
• 1 cup beef broth
• 1 tbsp Worcestershire sauce
• 1 tsp dried thyme
• 1 tsp salt
• ½ tsp black pepper

How to Make (Step-by-Step)

Preheat your oven to 400°F (200°C).

Set the rack in the middle and give the oven time to reach that steady heat. I like to start the mash while the oven warms up. A hot oven crisps those potato peaks nicely.

In a large skillet, heat oil over medium heat.

Add chopped onions and diced carrots and sauté for about five minutes until they soften. Stir frequently and keep the heat steady so they don’t brown too fast. The softened veggies build flavor and stop the meat from tasting one-note.

Add ground lamb or beef and dried thyme. Cook until browned (7-10 minutes), breaking apart the meat.

Brown the meat evenly and use a spoon to crumble it into small pieces. I keep the heat medium-high so the meat gets color without drying out. Season with a little salt and pepper at this stage to build layers of flavor.

Stir in beef broth and Worcestershire sauce; simmer on low for 10 minutes until thickened.

Let the liquid reduce slightly so the filling clings to the meat. Taste and adjust seasoning; add a pinch more salt or thyme if it needs a lift. Add peas in the last minute so they stay bright and just tender.

Meanwhile, mash boiled potatoes with butter, milk, salt, and pepper until creamy yet firm.

I aim for fluffy but spoonable mash that holds peaks. Use butter generously; it makes the top crisp and golden. If the mash gets runny, add a little more cooled mashed potato or reduce the milk.

In a baking dish, layer the meat mixture and top with mashed potatoes. Create peaks for crispiness.

Smooth the mash with a spatula or fork, then drag the tines to make little ridges. Those ridges brown slightly and taste amazing, so don’t be shy. Wipe the dish edges clean so the presentation looks neat.

Bake for 25-30 minutes until golden brown.

The top should crisp and the filling should bubble at the sides. If the peaks brown too quickly, tent foil loosely and finish roasting. Let it rest for ten minutes before serving so it sets and slices cleanly.

Pro Tips for the Best Results

• Use lamb for authenticity, but beef works if you prefer milder flavor.
• Drain excess fat after browning to prevent a watery filling.
• Add a splash of stock or cream to the mash for silkier texture.
• Season in layers: taste the meat, then taste the whole filling before baking.
• Make attractive peaks and brush with melted butter for extra browning.
• Rest before slicing to avoid a saucy mess on your plate.
• FYI: pre-boil potatoes while you prep veggies to save time.
• Use a wide skillet so the meat browns instead of steams.
• Freeze in portions for quick dinners later—just reheat gently.
• If unsure about seasoning, err on the side of slightly under-salted; you can always add at the table.

Fun Variations & Topping Ideas

Variations:

• Swap lamb for beef for a classic cottage pie twist.
• Stir in cooked mushrooms or a splash of stout for richer depth.
• Use sweet potato mash for a slightly sweeter, healthier option.
• Mix cooked barley or lentils with the meat to bulk it up and add texture.

Toppings:

• Sprinkle grated cheddar for an ultra-gooey lid.
• Crumble crispy bacon on top after baking for crunch.
• Mix Parmesan into mash for savory complexity.
• Brush melted butter and drizzle a tiny bit of olive oil to promote even browning.

Storing and Reheating

Cool the pie to room temperature before refrigerating in an airtight container. Refrigerate for up to three days; freeze for up to three months wrapped well. Reheat single slices in a skillet covered, or warm the whole dish at 350°F for 20–25 minutes. If reheating from frozen, thaw overnight then heat gently so the mash doesn’t separate.

Leftover ideas

• Turn slices into handheld pies by stuffing between puff pastry and baking until golden.
• Use leftovers as a filling for shepherd’s pie waffles if you enjoy experiments.
• Mix chunks into a soup for an instant meaty, comforting boost.
• Layer leftover pie into a breakfast hash with eggs for a morning treat.
• Blend cold leftovers with a splash of stock for a quick, rustic sauce over pasta.

Frequently Asked Questions (FAQ)

Can I make this vegetarian?

Yes—swap the meat for lentils and mushrooms and use vegetable broth. I often add cooked lentils for texture and umami. Season well and finish with the same creamy mash so you don’t lose that comforting mouthfeel.

Can I freeze the pie?

Absolutely. Cool completely, wrap tightly with foil and plastic, and freeze. Thaw overnight in the fridge, then reheat covered at 350°F until hot. The texture stays good if you avoid reheating at too high a temperature.

What side dishes pair well?

Keep it simple: a green salad, roasted root vegetables, or steamed greens work well. I like a sharp vinegar dressing to cut the richness. Soda bread or crusty rolls make the meal feel properly Irish.

Can I use instant mashed potatoes?

You can, but homemade mash tastes better and crisps nicer. If you use instant, add butter and a splash of milk, then beat until smooth. Don’t overwork it or it will go gluey.

How can I make the filling less runny?

Brown the meat properly and drain excess fat. Reduce the broth until the mixture thickly coats the back of a spoon. If needed, stir in a teaspoon of cornstarch mixed with cold water and simmer briefly.

Is shepherd’s pie actually Irish?

Yes, shepherd’s pie traces roots to the British Isles with regional names and tweaks. Shepherd’s pie traditionally uses lamb; “cottage pie” usually uses beef. IMO, the best part lies in the mashed potato crown, not the label.
