Shepherd’s Pie

(from wetherstorms’s recipe box)

Serves 4 to 6
Don’t use ground beef that’s fattier than 93 percent or the dish will be greasy.

WHY THIS RECIPE WORKS:
The traditional version of this dish of meat and gravy topped with mashed potatoes is time-consuming to make, and the end product is a bit heavy for modern palates. We streamlined the process by building and serving the pie in one skillet and by using lean ground beef rather than braised chunks of meat. To keep the meat tender, we treated it with baking soda, which raised the pH and kept the proteins from bonding too tightly, and we simmered the meat in the gravy rather than seared it. To replace the browned meat flavors that usually form the basis of the sauce, we sautéed the onions, mushrooms, and tomato paste in the skillet until quite dark, and then we deglazed the pan with fortified wine.

Ingredients

  • 1 1/2 pounds 93 percent lean ground beef
  • 2 tablespoons plus 2 teaspoons water
  • Salt and pepper
  • 1/2 teaspoon baking soda
  • 2 1/2 pounds russet potatoes, peeled and cut into 1-inch chunks
  • 4 tablespoons unsalted butter, melted
  • 1/2 cup milk
  • 1 large egg yolk
  • 8 scallions, green parts only, sliced thin
  • 2 teaspoons vegetable oil
  • 1 onion, chopped
  • 4 ounces white mushrooms, trimmed and chopped
  • 1 tablespoon tomato paste
  • 2 garlic cloves, minced
  • 2 tablespoons Madeira or ruby port
  • 2 tablespoons all-purpose flour
  • 1 1/4 cups beef broth
  • 2 teaspoons Worcestershire sauce
  • 2 sprigs fresh thyme
  • 1 bay leaf
  • 2 carrots, peeled and chopped
  • 2 teaspoons cornstarch

Directions

  1. Toss beef with 2 tablespoons water, 1 teaspoon salt, 1/4 teaspoon pepper, and baking soda in bowl until thoroughly combined. Set aside for 20 minutes.

  2. Meanwhile, place potatoes in medium saucepan; add water to just cover and 1 tablespoon salt. Bring to boil over high heat. Reduce heat to medium-low and simmer until potatoes are soft and tip of paring knife inserted into potato meets no resistance, 8 to 10 minutes. Drain potatoes and return to saucepan. Return saucepan to low heat and cook, shaking pot occasionally, until any surface moisture on potatoes has evaporated, about 1 minute. Remove pan from heat and mash potatoes well. Stir in melted butter. Whisk together milk and egg yolk in small bowl, then stir into potatoes. Stir in scallion greens and season with salt and pepper to taste. Cover and set aside.

  3. Heat oil in broiler-safe 10-inch skillet over medium heat until shimmering. Add onion, mushrooms, 1/2 teaspoon salt, and 1/4 teaspoon pepper; cook, stirring occasionally, until vegetables are just starting to soften and dark bits form on bottom of skillet, 4 to 6 minutes. Stir in tomato paste and garlic; cook until bottom of skillet is dark brown, about 2 minutes. Add Madeira and cook, scraping up any browned bits, until evaporated, about 1 minute. Stir in flour and cook for 1 minute. Add broth, Worcestershire, thyme, bay leaf, and carrots; bring to boil, scraping up any browned bits. Reduce heat to medium-low, add beef in 2-inch chunks to broth, and bring to gentle simmer. Cover and cook until beef is cooked through, 10 to 12 minutes, stirring and breaking up meat chunks with 2 forks halfway through. Stir cornstarch and remaining 2 teaspoons water together in bowl. Stir cornstarch mixture into filling and continue to simmer for 30 seconds. Remove thyme and bay leaf. Season with salt and pepper to taste.

  4. Adjust oven rack 5 inches from broiler element and heat broiler. Place mashed potatoes in large zipper-lock bag and snip off 1 corner to create 1-inch opening. Pipe potatoes in even layer over filling, making sure to cover entire surface. Smooth potatoes with back of spoon, then use tines of fork to make ridges over surface. Place skillet on rimmed baking sheet and broil until potatoes are golden brown and crusty and filling is bubbly, 10 to 15 minutes. Let cool for 10 minutes before serving.

  5. TECHNIQUE – SHEPHERD’S PIE MAKEOVER: Between trimming, searing, and braising chunks of stew meat and then mashing and piping the potato topping, traditional shepherd’s pie is an all-afternoon project. Plus, it’s hefty fare. Here’s how we freshened up the concept and got dinner on the table in about an hour. SWAP GROUND BEEF FOR STEW MEAT: Ground meat cooks in less than half the time required by bigger chunks and needs no butchering. BROWN VEGETABLES, NOT MEAT: Browning ground beef turns it pebbly. Instead, we brown vegetables and tomato paste to create a rich fond. LIGHTEN UP THE MASHED POTATOES: Less butter, milk instead of half-and-half, and sliced scallions lighten up the spuds.
