Ingredients for america's test kitchen shepherd's pie

Sixteen ingredients transform into a restaurant-worthy shepherd's pie with perfect texture contrast.

The ground beef makes or breaks this dish. 80% lean gives you that ideal meat-to-fat ratio for juicy, flavorful crumbles. Costco or Kroger carry finely ground beef perfect for this—avoid the extra-lean varieties. For the veggies, medium carrots (about 3) work best; they're sweet enough without being stringy. The potatoes? Russet or Yukon Gold—both hold their shape beautifully. I always buy extra potatoes for this recipe since they're the base of the flaky topping. Organic potatoes from the grocery store's fresh produce section have the best texture.

No beef broth? Low-sodium chicken broth works in a pinch. Fresh thyme is ideal but dried at one-third the amount gets you close. For the topping, heavy cream and milk combo creates that perfect balance of richness and lightness. Want to cut calories? Half-and-half plus a splash of milk works just as well. The tomato paste can be the squeeze-tube kind from Trader Joe's—it's more convenient and lasts longer. And that Parmesan? Freshly grated from a wedge makes all the difference over pre-grated.

Potatoes keep best in a cool, dark place for up to 2 weeks—don't refrigerate them. The beef mixture can be prepped ahead and refrigerated for 2 days before baking. For the flakiest topping, don't overmix the mashed potatoes—just mash until smooth. Assemble the pie and refrigerate overnight if you're making it ahead—the flavors meld beautifully. Once baked, it reheats perfectly in the oven at 350°F for 20 minutes.

Step-by-step instructions for america's Test Kitchen shepherd's pie

Master the technique for a perfectly flaky crust over rich, savory filling.

Peel the 2.5 lb russet potatoes and cut them into even 1-inch chunks. Place them in a large pot and cover with cold water by about 2 inches. Add 1.5 tsp salt and bring to a boil over high heat. Once boiling, reduce to a gentle simmer and cook for 15-20 minutes until completely tender.

Drain the potatoes thoroughly, then return them to the pot. Add the 0.5 cup unsalted butter, 0.25 cup whole milk, 0.25 cup heavy cream, and 0.25 cup grated parmesan cheese. Using a potato masher or ricer, mash until completely smooth with no lumps. Season with an additional 0.5 tsp salt if needed. The texture should be velvety and thick enough to hold its shape when spread.

In a large skillet over medium-high heat, add the 1.5 lb ground beef and cook, breaking it apart with a wooden spoon, until no longer pink (8-10 minutes). Drain excess fat, leaving about 1 tablespoon in the pan. Add the 1 whole yellow onion and 3 medium carrots, cooking for 5-6 minutes until softened.

Stir in the 4 cloves minced garlic, 2 tbsp tomato paste, 1 tsp dried thyme, and 0.5 tsp black pepper. Cook for 1 minute until fragrant. Sprinkle the 2 tbsp all-purpose flour over the mixture and stir to coat evenly. Slowly pour in the 1.5 cups beef broth, scraping up any browned bits from the bottom of the pan. Simmer for 8-10 minutes until the sauce thickens slightly and the flavors meld together.

Preheat your oven to 400°F. Spread the mashed potato mixture evenly over the meat filling in a 9x13-inch baking dish, creating a smooth, even layer. Use a fork to create a textured surface for better browning. Bake uncovered for 25-30 minutes until the top is golden brown and the edges are crispy.

For extra flakiness, broil for 1-2 minutes at the end, watching closely to prevent burning. The filling should be bubbling hot and the crust should be firm to the touch. Let the shepherd's pie rest for 10 minutes before serving to allow the filling to set and the flavors to settle.

Cut into squares and serve immediately while the filling is hot and the crust is still crisp. The contrast between the flaky, golden potato topping and the rich, savory meat filling is what makes this dish exceptional. Each bite should deliver a perfect balance of textures and flavors.

For best results, serve with a side of steamed green beans or a simple salad to complement the hearty filling. The leftovers reheat beautifully, making this a great meal-prep option for busy weeks.

Dietary considerations for america's test kitchen shepherd's pie

Gluten-Free Adaptation

Replace the 2 tbsp all-purpose flour in the gravy with 2 tbsp cornstarch or gluten-free flour blend like Bob's Red Mill 1:1. The cornstarch works best for thickening since it's naturally gluten-free and creates a smooth sauce.

For extra richness, add 1 tbsp butter to the gravy while simmering—this helps compensate for any slight texture difference. 🥔

Dairy-Free Options

Swap the heavy cream and butter in the mashed potatoes for full-fat coconut milk (about ½ cup) and olive oil (about ¼ cup). For the topping, use unsweetened almond milk instead of regular milk.

The Parmesan can be replaced with nutritional yeast for a cheesy flavor without dairy. The texture will be slightly lighter but still delicious.

Vegetarian Version

Replace the ground beef with lentils (about 1.5 cups cooked) or mushrooms (about 1.5 lbs finely chopped cremini). For lentils, simmer them with 1 cup beef broth and 1 tsp soy sauce until tender.

For mushrooms, sauté them until deeply browned and add 1 tbsp tomato paste for depth. The gravy can stay the same, but add 1 tsp smoked paprika to enhance the savory flavor.

Lower-Carb Modifications

Reduce the potato topping by half (about 1.25 lb potatoes) and mix in ½ cup cauliflower rice to the mashed potatoes. For extra flavor, add 1 tsp garlic powder and ½ tsp onion powder to the filling.

This keeps the dish hearty while cutting carbs significantly. The texture will be slightly different but still satisfying.

Allergen-Friendly Tips

For nut allergies, ensure your gluten-free flour blend is nut-free (many contain almond flour). If dairy is a concern, use dairy-free butter (like Earth Balance) and soy-free coconut milk.

Always check labels on broths—some contain hidden gluten or dairy. For soy-free options, use coconut aminos instead of soy sauce in the vegetarian version.
