Ingredients

Scale
  • 1.5 lbs ground lamb (preferably grass-fed)
  • 1 large onion, finely chopped
  • 2 cloves garlic, minced
  • 2 medium carrots, diced
  • 1 cup frozen peas
  • 2 tbsp tomato paste
  • 1 cup Guinness beer (room temperature)
  • 1 cup beef or vegetable broth
  • 2 tsp Worcestershire sauce
  • 2 tbsp all-purpose flour (or gluten-free flour/cornstarch for GF version)
  • 1 tbsp olive oil or vegetable oil
  • Salt and freshly ground black pepper, to taste
  • 2 lbs Yukon Gold potatoes, peeled and cut into chunks
  • 4 tbsp unsalted butter, softened
  • 1/2 cup whole milk or cream (or dairy-free milk)
  • Salt and freshly ground black pepper

Instructions

  1. Preheat the oven to 400°F (200°C).
  2. Place peeled and chopped Yukon Gold potatoes in a large pot, cover with cold water, add a pinch of salt, and bring to a boil. Cook for 15-20 minutes or until fork-tender. Drain and set aside.
  3. Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add ground lamb and cook until browned, breaking it up with a wooden spoon, about 6-8 minutes. Remove excess fat if needed.
  4. Add chopped onion, garlic, and diced carrots to the skillet. Cook until softened, about 5 minutes, stirring occasionally.
  5. Sprinkle 2 tbsp flour over the meat and vegetables, stirring well to coat.
  6. Slowly add 1 cup Guinness and 1 cup broth, stirring constantly to avoid lumps. Add Worcestershire sauce, tomato paste, salt, and pepper.
  7. Reduce heat to medium-low and simmer for about 15 minutes until gravy thickens and flavors meld. Add frozen peas in the last 5 minutes of cooking.
  8. Mash the cooked potatoes with butter and milk until smooth and creamy. Season with salt and pepper to taste.
  9. Spoon the lamb and Guinness gravy mixture into an oven-safe baking dish. Spread mashed potatoes evenly over the top and create peaks with a fork to help browning.
  10. Bake in the preheated oven for 20-25 minutes or until the potato topping is golden brown and the filling is bubbling.
  11. Let the shepherd’s pie rest for 5-10 minutes before serving.

Notes

Use room temperature Guinness to prevent gravy from seizing. For gluten-free, substitute flour with cornstarch or gluten-free flour blend. Yukon Gold potatoes provide a naturally buttery flavor and mash smoothly. Let the pie rest before serving for easier portioning and better flavor melding. You can prepare filling and mashed potatoes a day ahead for convenience.
