Ingredients for america's test kitchen shepherd's pie

Sixteen ingredients transform simple comfort food into restaurant-worthy shepherd's pie.

The ground beef is where the flavor starts—85% lean gives you that perfect meaty richness without excess fat. Costco or Trader Joe's usually carry the finest grind for this dish. Look for bright red color and good marbling if buying whole cuts to grind yourself. The carrots and onions should be finely diced—no bigger than 1/4 inch—so they melt into the filling. Fresh thyme is ideal, but the dried works in a pinch at one-third the amount. For the potatoes, Russets or Yukon Golds are your best bet—they're starchy enough to hold their shape while still giving that creamy texture.

No beef broth? Low-sodium chicken broth works just as well. Fresh thyme unavailable? Dried works at one-third the amount. The tomato paste can be swapped for 1/2 cup crushed tomatoes if you prefer. For the topping, Panko breadcrumbs give the best crisp without burning, but regular breadcrumbs work too. The butter needs to be cold and cubed—don't melt it first. If you're watching calories, use half-and-half instead of whole milk in the mashed potatoes. The flour in the topping is non-negotiable—it's what creates that perfect crispy crust without drying out the potatoes underneath.

Potatoes keep best in a cool, dark place for up to 2 weeks—don't refrigerate them. The ground beef should be used within 2 days of purchase for best texture. Once assembled, this shepherd's pie reheats beautifully—350°F for 25-30 minutes until the topping is golden. Leftovers keep for 4-5 days in the fridge, or freeze for 3 months. I always make a double batch—one for dinner, one to freeze for lazy weeknights.

Step-by-step instructions for america's test kitchen shepherd's pie

Here's the method that guarantees a rich beef filling and velvety mashed potato topping that stays moist and flavorful.

Heat a large skillet over medium-high heat and add the 1.5 lb ground beef. Break it apart with a wooden spoon and cook until browned, breaking it into small pieces as it cooks. This takes about 5-6 minutes—don't rush it, as proper browning builds deep flavor.

Once the beef is browned, add the 1 whole yellow onion and 3 medium carrots (both finely diced) to the skillet. Cook for 8-10 minutes until the vegetables soften and the onion becomes translucent. Stir occasionally to prevent sticking. Here's where the magic happens—those caramelized onions will add sweetness to your filling.

After the vegetables soften, add the 4 cloves minced garlic and the 2 tbsp tomato paste. Stir well and cook for another 1-2 minutes until the garlic is fragrant. This step develops the base flavors that will carry through your entire dish.

Pour in the 1 cup beef broth and scrape up all the browned bits from the bottom of the pan with a wooden spoon. These bits are packed with flavor—don't miss this step! Add the 1 tsp dried thyme, 1.5 tsp salt, and 0.5 tsp ground black pepper, then bring the mixture to a simmer.

Reduce the heat to medium-low and let the filling cook uncovered for 10-12 minutes until it thickens slightly. You want the liquid to reduce but not completely evaporate—it should coat the back of a spoon. The filling should be moist but not soupy. If it's too thin, simmer for another 2-3 minutes to reach the right consistency.

While the filling simmers, peel the 2.5 lb russet potatoes and cut them into 1-inch chunks. Place them in a large pot and cover with cold water by about 1 inch. Bring to a boil over high heat, then reduce to a simmer and cook for 12-15 minutes until fork-tender.

Drain the potatoes thoroughly, then return them to the pot. Add the 0.5 cup unsalted butter (cold and cubed) and 0.5 cup whole milk. Mash until smooth and creamy—no lumps allowed. For extra-smooth potatoes, I like to press them through a ricer or use a potato masher before adding the butter and milk. Season with an additional pinch of salt if needed.

Preheat your oven to 400°F. Spread the beef filling evenly in a 9x13-inch baking dish, creating a base layer about ½-inch thick. Smooth the top with a spatula for an even surface. This even layer ensures the potatoes cook through without burning on top.

Spread the mashed potatoes over the filling, creating a smooth, even layer. For that perfect crispy topping, mix the 0.5 cup panko breadcrumbs with the 1 tbsp all-purpose flour and sprinkle evenly over the potatoes. Bake uncovered for 25-30 minutes until the topping is golden brown and the filling is bubbling around the edges.

Remove the shepherd's pie from the oven and let it rest for 10 minutes before serving. This resting time allows the filling to set slightly and the flavors to meld together. The potatoes will be hot but not scorched, and the topping will be crispy rather than gummy.

Cut into squares and serve immediately. Each bite should deliver tender, flavorful beef with creamy potatoes that stay moist and velvety. The crispy breadcrumb topping adds texture contrast, making every mouthful perfect. Leftovers reheat beautifully—just cover with foil and warm in the oven for 10-15 minutes at 350°F.

Wine and beer pairings for this dish

Classic Red Wine

A bold Cabernet Sauvignon from Napa Valley is my go-to pairing for this hearty shepherd's pie. Its rich dark fruit flavors and firm tannins stand up to the savory beef filling while complementing the creamy mashed potatoes.

Look for a 2018 or newer vintage with 14-15% alcohol—just enough body to match the dish's richness without overpowering it. 🍷

English-Style Ale

For beer lovers, a robust English-style brown ale like Fuller's ESB bridges the gap between hearty and approachable. The caramel and toasty malt notes harmonize with the caramelized onions in the filling, while the subtle hop bitterness cuts through the richness.

Serve slightly chilled (45-50°F) to enhance its malty profile without numbing your palate.

Malbec for Spice Lovers

If you prefer a touch of spice, an Argentinian Malbec with its dark plum and peppery finish makes an excellent match. The wine's natural acidity balances the dish's creaminess, while its velvety texture mirrors the mashed potato topping.

Try a Trapiche Malbec—it's widely available and consistently delivers 14% alcohol with vibrant fruit flavors.

Light White Wine

For those who prefer white wine, a crisp Chardonnay from Burgundy offers surprising harmony. Choose an unoaked version with bright citrus notes to contrast the dish's richness.

The wine's acidity refreshes your palate between bites, while its mineral finish complements the earthy flavors of the vegetables. Serve at 50-55°F for optimal balance.

Seasonal Adaptations

In warmer months, swap the red wine for a Pinot Noir—its lighter body and red fruit flavors won't feel as heavy. For beer, try a Belgian-style witbier like Hoegaarden during summer months; its citrusy notes provide a refreshing contrast to the savory filling.

The key is always matching the wine or beer's acidity and body to the dish's richness.

Non-Alcoholic Options

Don't overlook non-alcoholic pairings! A sparkling ginger beer like Feather's provides effervescence that cleanses your palate between bites. For a more traditional option, try a dry hard cider—the apple and pear notes complement the caramelized onions beautifully.

Both options should be served well-chilled (40-45°F) to enhance their refreshing qualities. ✨
