Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Boil 2 lbs peeled and quartered potatoes in salted water for 20 minutes until tender.
  2. Step 2: While potatoes cook, heat 1 tbsp olive oil in a large skillet over medium-high heat. Add 1 lb ground beef and cook for 5-6 minutes, breaking into crumbles until browned. Remove excess fat.
  3. Step 3: Add 1 diced medium onion and 1 diced medium carrot to the beef, sauté for 5 minutes until softened.
  4. Step 4: Stir in 2 tbsp tomato paste and 1 tbsp all-purpose flour, cooking for 1 minute to remove raw flour taste.
  5. Step 5: Pour in 1 cup beef broth and 1 tbsp Worcestershire sauce, simmer for 5 minutes until mixture thickens slightly. Fold in 1 cup frozen peas and season with 1 tsp salt and 1/2 tsp black pepper.
  6. Step 6: Drain potatoes and mash with 4 tbsp butter, 1/2 cup milk, and 3 minced garlic cloves until smooth and creamy.
  7. Step 7: Transfer beef mixture to a 9x9 inch baking dish and spread evenly. Top with mashed potatoes, smoothing the surface with a spatula.
  8. Step 8: Bake for 20 minutes at 400°F until the potato topping is golden around the edges and the filling bubbles.
  9. Step 9: Let rest for 5 minutes before serving to set flavors.

How do I store leftover Shepherd's Pie with Garlic Mashed Potato Topping?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep ground beef from drying out.

Can I substitute ingredients in Shepherd's Pie with Garlic Mashed Potato Topping?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Shepherd's Pie with Garlic Mashed Potato Topping for a different number of people?

The recipe is written for 6 servings. Multiply each ingredient by (your serving target / 6). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
