Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Place 3 large peeled and quartered russet potatoes into a large pot of salted water and bring to a boil. Cook for 15-18 minutes until potatoes are fork-tender.
  2. Step 2: While potatoes cook, heat 1 tbsp olive oil in a large skillet over medium-high heat. Add 1 medium diced yellow onion and 2 diced medium carrots, sauté for 5 minutes until softened.
  3. Step 3: Add 1 lb ground beef to the skillet with the vegetables, breaking it up with a spatula. Cook for 6-8 minutes until browned and cooked through, then stir in 2 tbsp tomato paste, 1 cup beef broth, 1 tbsp Worcestershire sauce, 2 tbsp all-purpose flour, 1 tsp salt, and 1/2 tsp black pepper. Simmer for 5 minutes until sauce thickens and coats the meat.
  4. Step 4: Stir in 1 cup frozen peas and cook for an additional 2 minutes. Remove from heat.
  5. Step 5: Drain the cooked potatoes and return to the pot. Add 4 tbsp unsalted butter, 1/2 cup whole milk, and 3 minced garlic cloves. Mash until smooth and fluffy. Season with salt to taste.
  6. Step 6: Spread the beef mixture evenly in a 9x9-inch baking dish. Dollop the garlic mashed potatoes on top and spread evenly with a spatula. Use a fork to create shallow ridges on the surface for crisp edges.
  7. Step 7: Bake in the preheated oven for 20-25 minutes until the potato topping is lightly golden and edges are bubbling. Let cool for 5 minutes before serving.

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 Layered Shepherd's Pie with Garlic Mashed Potatoes?
