1-First Step: Prepare the Meat Filling: Begin by heating 2 tablespoons olive oil in a large skillet over medium-high heat. Add 1 cup chopped yellow onion and cook for 5 minutes, stirring occasionally, until the onions soften and turn translucent. This sets the base for a flavorful filling in your authentic shepherds pie recipe.

2-Second Step: Brown the Meat: Next, add 1 pound ground beef or lamb to the skillet, along with 2 teaspoons dried parsley, 1 teaspoon dried rosemary, 1 teaspoon dried thyme, 1/2 teaspoon salt, and 1/2 teaspoon ground black pepper. Break the meat apart and cook for 6-8 minutes until it’s fully browned and no pink remains, releasing those savory aromas.

3-Third Step: Add Sauces and Vegetables: Stir in 1 tablespoon Worcestershire sauce and 2 minced garlic cloves, cooking for 1 more minute to let the flavors meld. Then, add 2 tablespoons all-purpose flour and 2 tablespoons tomato paste, stirring well to combine and create a thick base for the gravy.

4-Fourth Step: Simmer the Mixture: Pour in 1 cup beef broth, 1 cup frozen mixed peas and carrots, and 1/2 cup frozen corn kernels, bringing it to a boil. Once boiling, reduce the heat and simmer for 5 minutes until the mixture thickens nicely, then set it aside to cool slightly for easier handling.

5-Fifth Step: Cook the Potatoes: Preheat your oven to 400°F while you prepare the topping. Boil 1 ½ to 2 pounds of peeled and cubed russet potatoes in a pot of water for 10-15 minutes until they’re fork-tender. Drain them, return to the pot for 1 minute to dry, then mash with 8 tablespoons butter, 1/3 cup half & half, 1/2 teaspoon garlic powder, 1/2 teaspoon salt, and 1/4 teaspoon ground black pepper. Finally, stir in 1/4 cup parmesan cheese for a cheesy finish.

6-Sixth Step: Assemble and Bake: Transfer the meat mixture to a 9×9 or 7×11-inch baking dish, spreading it evenly. Top with the mashed potatoes, smoothing them out to cover the filling completely. Place the dish on a rimmed baking sheet and bake for 25-30 minutes until it’s bubbling and the top is golden brown. Let it cool for 15 minutes before serving to allow the flavors to settle.
