Instructions
Step 1: Make the PotatoesPlace the peeled and cubed potatoes in a large pot and cover with cold water and a sprinkle of salt. Bring to a boil and cook for 15–20 minutes, or until fork tender. Drain well, then mash with the butter, milk, salt, and pepper until smooth and creamy. Set aside while you make the filling.
Step 2: Soften the VegetablesPreheat your oven to 400°F. In a large oven-safe skillet or heavy pan, melt the butter over medium heat. Add the onion and carrots and cook for 5–6 minutes, until softened. Stir in the garlic and cook for about 30 seconds, just until fragrant.
Step 3: Cook the MeatAdd the ground lamb and cook until browned, breaking it up as it cooks. If there is a lot of grease, carefully drain off the excess. Stir in the tomato paste, Worcestershire sauce, thyme, salt, and pepper. Sprinkle the flour over the meat mixture and stir for about 1 minute.
Step 4: Add the BrothSlowly pour in the broth, stirring well so everything combines smoothly. Let the mixture simmer for 3–5 minutes, until slightly thickened, then stir in the peas.
Step 4: Assemble Spread the mashed potatoes evenly over the lamb filling, smoothing the top with a wooden spoon or spatula. Use a fork to create a few ridges across the top - this helps the potatoes brown nicely in the oven. Sprinkle with cheddar cheese if using.
Step 5: BakeBake for 20–25 minutes, until bubbling around the edges and golden on top. Let the shepherd’s pie rest for about 10 minutes before serving so it holds together better when scooped.
Notes
Use a Heavy Pan
A cast-iron skillet works especially well because it holds heat beautifully and gives better browning.
Don’t Skip the Fork Marks
Those little ridges help the potatoes crisp and brown instead of staying flat and pale.
