Ingredients for america's test kitchen shepherd's pie
Sixteen ingredients transform into America's Test Kitchen's legendary crispy-topped shepherd's pie.
| Ingredient | Amount | Notes |
|---|---|---|
| Ground Beef 🥩 | 1 ½ lb | 80/20 fat ratio preferred |
| Yellow Onions 🧅 | 2 whole | Medium size, diced fine |
| Fresh Peas 🌽 | 1 cup | Frozen works perfectly |
| Russet Potatoes 🥔 | 3 lb | Starchy variety for best mash |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness |
| Whole Milk 🥛 | ¼ cup | Warmed for silky mash |
| Unsalted Butter 🧈 | ¼ cup | Cold, cubed for best flavor |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Worcestershire Sauce 🍶 | 1 tbsp | For umami depth |
| Fresh Thyme 🌿 | 1 tbsp | Leaves only, chopped |
| Garlic Cloves 🧄 | 3 cloves | Minced for filling |
| Olive Oil 🫒 | 1 tbsp | For meat browning |
| Beef Broth 💧 | 1 ½ cups | Low-sodium preferred |
The beef is your flavor foundation—80/20 fat ratio gives that deep, savory punch. Kroger's Select or Costco's Kirkland brands are my go-tos for consistent quality. Caramelize those onions until they're golden brown—30 minutes minimum—that sweetness balances the meat's richness. Fresh thyme makes all the difference here, but if you're using dried, reduce to 1 teaspoon. The potatoes? Russets are non-negotiable—their starchiness creates that perfect creamy-yet-crispy topping. Buy them a day ahead and let them sit out for even better texture.
No Worcestershire? Soy sauce plus a pinch of sugar mimics that umami-sweet combo. Swap frozen peas for fresh if you prefer, but don't overcook them—they should stay vibrant. Running short on butter? Olive oil works in a pinch, though it won't be quite as rich. The beef broth can be subbed with water plus 1/2 teaspoon beef bouillon, but you'll lose some depth. For the mash, if you're worried about lumps, add the potatoes directly to the cream and milk instead of boiling first. And trust me on the heavy cream—light cream won't give that same velvety texture.
This pie reheats like a dream—425°F for 20-25 minutes until the edges are golden. Leftovers keep 4-5 days in the fridge, but honestly, it's even better the next day as all the flavors meld. For make-ahead magic, assemble the pie day before, refrigerate uncovered for 1 hour to dry the top slightly, then cover and bake when ready. The topping will crisp up beautifully. Portion into individual ramekins for single servings—perfect for meal prep. And if you're feeling fancy, sprinkle crumbled bacon or fresh parsley on top before baking.
Why You'll Love This Recipe

Step-by-step instructions for america's Test Kitchen shepherd's pie
Here's the foolproof method for a restaurant-quality shepherd's pie with a golden crust that seals in all that savory goodness.
🍳 Step 1: Brown the Ground Beef Perfectly
Heat the 1 tablespoon olive oil in a large skillet over medium-high heat until shimmering. Add the 1.5 lb ground beef and break it apart with a wooden spoon, letting it brown in batches to avoid overcrowding. You want those pieces to develop a deep, rich color—this builds incredible flavor.
Once the beef is mostly browned, add the 2 whole yellow onions (finely diced) and cook for 5-6 minutes until softened. Stir in the 3 cloves garlic (minced) and the 1 tablespoon fresh thyme, cooking for another 30 seconds until fragrant. This aromatic base forms the flavor foundation for your filling.
🥘 Step 2: Build the Savory Filling
Pour in the 1 tablespoon Worcestershire sauce and let it bubble for 1 minute to deepen the umami. Add the 1.5 cups beef broth and scrape up all those delicious browned bits from the bottom of the pan—this is where all the flavor hides. Bring to a gentle simmer and cook for 8-10 minutes until the liquid reduces by about half.
Stir in the 1 cup fresh peas and season generously with 1.5 teaspoons salt and 0.5 teaspoon black pepper. The peas should be heated through but still vibrant. Remove from heat and let the mixture cool slightly—this prevents the mashed potato topping from getting soggy when you assemble it.
👨🍳 Step 3: Create Ultra-Smooth Mashed Potatoes
While the filling cools, peel and chop the 3 lb russet potatoes into even chunks. Place them in a large pot and cover with cold water by about 1 inch. Bring to a boil, then reduce to a simmer and cook for 15-20 minutes until fork-tender. Drain thoroughly and return to the pot.
Add the 0.25 cup unsalted butter (cold, cubed) and 0.5 cup heavy cream to the warm potatoes. Using a potato masher or ricer, work in the butter and cream until completely incorporated. Then stir in the 0.25 cup whole milk (warmed) until the mash is silky and smooth. Season with additional salt and pepper if needed—this should be rich and velvety.
🔥 Step 4: Assemble and Bake to Golden Perfection
Preheat your oven to 400°F. Spread the cooled beef mixture evenly in a 9x13-inch baking dish, creating a smooth surface. Spoon the mashed potatoes over the top, using the back of a spoon to create gentle swirls—this helps create that iconic rustic look.
Bake uncovered for 25-30 minutes until the top is deep golden brown and the edges are crispy. The key is to let it bake just until the crust forms—don't overbake or the top will dry out. Let it rest for 10 minutes before serving, allowing the filling to set slightly.
⏰ Step 5: Serve with Confidence
Use a sharp knife to cut through the crust and into the filling, creating clean slices that reveal the perfect golden-brown top and rich, savory beef mixture beneath. The crust should be crispy on top while staying creamy inside—this is where the magic happens. Serve immediately with a side of crusty bread to soak up any extra gravy.
This is the moment you've been waiting for—the perfect balance of textures and flavors. The crispy potato crust locks in all that hearty beef filling, creating a dish that's as comforting as it is impressive. Enjoy every bite of this classic comfort food done right!
Pro Tips For Making America'S Test Kitchen Shepherd'S Pie
- Sear the Beef First: The ATK recipe calls for browning the ground beef, but I learned the hard way—actually searing it in batches makes a huge difference. Use a 12-inch skillet over medium-high heat, break the beef into ¼-inch crumbles, and let it sit undisturbed for 30 seconds before stirring. That crusty brown bit? That’s flavor you can’t replicate otherwise.
- Boil Potatoes Until Fork-Tender: The recipe says "boil until tender," but I used to pull them out too soon—resulting in a mushy topping. Test doneness by piercing with a fork; if it slides in like butter, they’re ready. Drain immediately and let them steam-dry in the colander for 2 minutes. Cold potatoes mash better and won’t turn gluey when baked.
- Don’t Skip the Cream Reduction: The ATK method adds heavy cream at the end, but I used to just dump it in and call it a day. Instead, simmer the cream with the thyme and Worcestershire sauce for 2–3 minutes until slightly thickened. This step actually changes the texture—it coats the filling instead of pooling, and the flavor deepens. (Yes, even if you’re impatient like me.)
- Press the Topping Flat: The recipe mentions shaping the potato topping, but I used to eyeball it—leading to uneven baking and a dry top. Use a fork to press the mashed potatoes into a ½-inch-thick layer, then score the top in a crosshatch pattern. This guarantees even browning and that coveted crispy crust. (Your future self will thank you.)
Perfect pairings for this america's test kitchen shepherd's pie
Crispy Bread Sides
Serve your shepherd's pie with a crusty baguette or sourdough bread to soak up the rich gravy. I love using a baguette from Trader Joe's—it's perfect for tearing into chunks and toasting in the oven for 5 minutes at 375°F.
The crust absorbs the savory juices beautifully, adding another layer of texture to your meal. 🥖
Fresh Green Salad
A simple arugula salad with lemon vinaigrette cuts through the richness of the pie. Toss 4 cups baby arugula with 2 tablespoons olive oil, 1 tablespoon lemon juice, 1 teaspoon Dijon mustard, and a pinch of salt.
Top with ¼ cup shaved Parmesan cheese for a bright, tangy contrast. 🥗
Roasted Vegetable Medley
For a heartier side, roast carrots, Brussels sprouts, and sweet potatoes at 400°F for 25 minutes with 1 tablespoon olive oil, 1 teaspoon smoked paprika, and a sprinkle of salt. The caramelized edges complement the pie's savory filling perfectly. 🥕
Cheesy Potato Wedges
Elevate your meal with cheesy potato wedges—toss 2 cups baby potatoes (halved) with 1 tablespoon olive oil, 2 tablespoons grated Gruyère cheese, and 1 teaspoon rosemary. Roast at 425°F for 25-30 minutes until crispy. The extra cheesy note ties into the mashed potato topping. 🧀
Classic Beer Pairings
A stout beer like Guinness or Samuel Smith's Nut Brown Ale pairs wonderfully with shepherd's pie. The malty sweetness balances the savory filling, while the creamy texture of the stout complements the mashed potato topping.
For a lighter option, try a pale ale like Fat Tire—its citrus notes brighten the dish. 🍺
Wine Recommendations
For wine lovers, a medium-bodied red like Pinot Noir or Merlot enhances the dish's richness. The acidity in these wines cleanses your palate between bites, while their fruitiness complements the caramelized onions and thyme. A Chardonnay with light oak also works beautifully, especially if you prefer white wine. 🍷

Frequently asked questions
Can I make this shepherd's pie ahead of time?
Assemble the pie 24 hours ahead and refrigerate uncovered for 1 hour to dry the top slightly. Cover and refrigerate until ready to bake—this actually improves the texture. Bake straight from the fridge for 35-40 minutes at 400°F to achieve that perfect golden crust. The flavors meld beautifully overnight, making it even more delicious.
What's the secret to a crispy potato topping?
The magic is in the butter-fat ratio and oven temperature. Use cold cubed butter mixed into warm potatoes, then bake at 400°F uncovered until deep golden brown. Spread the filling evenly first—this prevents steam from making the bottom soggy. For extra crispiness, broil for 1-2 minutes at the very end.
Can I substitute lamb for beef?
Yes, but adjust the cooking time slightly. Lamb browns faster than beef, so cook it for just 3-4 minutes until no longer pink. The flavor profile changes dramatically—lamb gives a more gamey, robust taste that works beautifully with the same seasonings. Use the same quantity (1.5 lb) and reduce the Worcestershire to 1 teaspoon to prevent overpowering.
Why did my topping get soggy?
Most likely, your filling was too hot when assembling or the oven wasn't hot enough. Always let the filling cool completely before adding the potato topping. Preheat your oven to 400°F and place a baking sheet on the lower rack to catch any drips. If using a glass dish, try a metal one next time—glass conducts heat differently and can cause uneven cooking.
What's the best way to reheat leftovers?
Reheat at 425°F for 20-25 minutes covered with foil, then uncover for the last 5 minutes to crisp the top. For individual portions, microwave for 1 minute covered, then 30 seconds uncovered to revive the crust. Leftovers keep 4-5 days in the fridge—this dish actually tastes better the second day as flavors meld!
