This meal... it’s the one that gives you the warm and fuzzies. It has all the elements of a traditionalShepherd's Pie recipe—ground beef, mashed potatoes, and veggies—but with a few delicious upgrades: roasted garlic and Parmesan cheese in the potatoes, a mix of dried herbs, and some Worcestershire sauce for that rich umami kick.
Rinse and scrub the potatoes to remove any visible dirt, then peel and cut them into roughly 1-inch chunks.
1 ½ pounds russet potatoes
Add the potatoes to a large Dutch oven or pot and cover with at least 1 inch of water. Sprinkle in a pinch or two of salt and bring the water to a boil over high heat. Once boiling, reduce the heat to medium-low and maintain a rapid simmer for 10 minutes, or until the potatoes are fork-tender.
Drain the potatoes in a colander in the sink, then return them to the pot. Add the milk, butter, Parmesan cheese, 1 teaspoon salt, 1⁄4 teaspoon black pepper, and roasted garlic. Using a potato masher, mash everything together until smooth and creamy with very few chunks remaining. Set aside until ready to use.
½ cup whole milk, 4 tablespoons salted butter, ¼ cup grated Parmesan cheese, 2 ¼ teaspoons salt, ¾ teaspoon black pepper, 4 roasted garlic cloves
Heat the avocado oil in a large skillet or saucepan over medium heat. Once shimmering, add the onion and celery, and cook for 3-4 minutes, or until the onion is translucent. Add the garlic and continue cooking for 30 seconds, or until fragrant.
Push the vegetables to one side of the skillet and add the ground beef. Cook, breaking apart, for 7-8 minutes, or until no longer pink. Add the tomato paste, flour, Worcestershire sauce, thyme, rosemary, parsley, 1 1⁄4 teaspoons salt, and 1⁄2 teaspoon black pepper. Mix everything together until well combined.
Stir in the beef broth, reduce the heat to low, and let the mixture simmer for about 8-10 minutes, or until it has thickened and is no longer runny. Stir in the mixed vegetables and continue cooking for 2-3 minutes.
1 ½ cups beef broth, 1 ½ cups frozen mixed vegetables
Spray a 7 x 11-inch baking dish with nonstick cooking spray. Add the ground meat filling, spreading it out to cover the bottom of the dish. Place evenly spaced dollops of the mashed potatoes on top. Use a spatula to spread the potatoes out to completely cover the ground meat layer. Use the side of the spatula to create little peaks in the potatoes.
Bake the shepherd’s pie for 25-30 minutes. Turn the oven to broil and broil for 2-3 minutes, or until the edges are browned and crispy. Let the pie rest at room temperature for 10 minutes before serving. Sprinkle with fresh parsley, if desired.
