Shepherd’s Pie Recipe with Savory Lamb and Mashed Potatoes

Key Ingredients You Will Need

• Potatoes – Russet or Yukon Gold produce light, fluffy mashed potatoes. Peel or leave the skins on, but wash well first.
• Butter – Adds richness and moisture to the mashed potatoes.
• Sour cream – Makes the potatoes extra creamy and gives them a subtle tang. Full-fat or light both work.
• Ground beef – Use lean ground beef (about 85/15) to avoid excess grease. Ground lamb is a good substitute for a true shepherd’s pie.
• Mixed frozen vegetables – A convenient mix of peas, carrots, corn, and green beans keeps the filling simple and colorful. Fresh vegetables may be used instead.
• Flour – A small amount helps thicken the beef filling so it isn’t runny.
• Beef broth – Provides a rich, savory base for the sauce. Chicken stock can be used if preferred.
• Worcestershire sauce – Adds depth and savory umami to the meat mixture.
• Shredded cheddar cheese – Sprinkled on top for a melted, golden finish. Any cheddar or cheddar blend works well.

How to Make Shepherd’s Pie With Beef

1. Prepare the mashed potatoes. Cut potatoes into even pieces, cover with cold water, add a pinch of salt, and boil until fork-tender. Drain, then mash with butter, sour cream, salt, garlic powder, and a splash of milk until smooth and creamy.
2. Cook the aromatics and beef. Heat olive oil in a large skillet over medium heat. Sauté chopped onion until translucent, add minced garlic, then brown the ground beef, seasoning with salt and pepper.
3. Thicken the filling. Stir frozen mixed vegetables into the beef, sprinkle with flour, then pour in beef broth, tomato paste, and Worcestershire sauce. Bring to a gentle boil and simmer for 2–3 minutes until the sauce thickens slightly.
4. Assemble the casserole. Preheat the oven to 400°F (200°C). Spread the beef mixture into a sprayed 9″ x 9″ (or similar) baking dish. Top with spoonfuls of mashed potatoes, smoothing or creating a textured surface as you like. Sprinkle shredded cheddar evenly over the potatoes.
5. Bake until golden. Bake about 20 minutes, until the filling bubbles and the cheese is melted and golden. Let the dish rest a few minutes before serving.

Recipe Tips

• Wash potatoes thoroughly and cut into similar-sized pieces so they cook evenly.
• Start potatoes in cold water, then bring to a boil to ensure uniform cooking.
• Salt the cooking water to season the potatoes as they boil.
• A hand masher gives a rustic texture; for silkier potatoes, use a ricer or mixer on low speed.
• Smaller potato pieces will boil faster and save time.

Frequently Asked Questions
