A layered beef and potato bake similar to shepherd's pie, seasoned with cumin, olives and hard-boiled egg.
Pastel de papa is Argentina's take on a layered meat and potato pie, similar in structure to shepherd's pie but distinctly seasoned with cumin, green olives and often a layer of sliced hard-boiled egg tucked into the beef filling, reflecting the same Spanish-influenced flavors found in empanadas and other Argentinian beef dishes. Ground beef is cooked down with onion, tomato and raisins in some versions, giving the filling a sweet-savory balance typical of Argentine picadillo-style fillings. The potato topping is mashed smooth with butter and milk, then spread over the beef filling and often finished under the broiler until the peaks turn golden and slightly crisp, similar to a French gratin. Some households pipe the mashed potato decoratively before broiling, though a simple spread with a fork-textured surface browns just as well and is far less fuss for a weeknight dinner. Served hot from the baking dish, pastel de papa is classic Argentine home cooking -- comforting, economical, and built to stretch a modest amount of ground beef into a filling family dinner using potatoes and pantry staples.
Serves 6
Boil potatoes in salted water until fork-tender, about 20 minutes. Drain and mash with butter, warm milk and 1 teaspoon salt until smooth.
Heat olive oil in a skillet over medium heat. Cook onion until soft, add garlic and cook 1 minute, then add ground beef and brown, breaking it up, about 8 minutes.
Stir in tomatoes, cumin, remaining salt and pepper. Simmer 8 to 10 minutes until the tomatoes break down and the mixture thickens.
Cook the filling until most of the liquid has evaporated -- a wet filling will make the potato layer slide around instead of setting into distinct layers.
Stir in chopped olives and raisins if using. Remove from heat.
Spread the beef filling in a greased baking dish, arrange sliced hard-boiled eggs over the top, then spread the mashed potato evenly over everything, sealing to the edges of the dish.
Bake at 400°F (200°C) for 20 minutes, then switch to broil for 3 to 5 minutes until the potato top turns golden brown in spots.
Let rest 5 minutes before serving hot, straight from the baking dish.
Cook the beef filling until most of the liquid has evaporated -- a watery filling makes it hard for the potato layer to hold its shape once cut.
Rough up the surface of the mashed potato with a fork before broiling; the ridges catch more color and crisp up nicely under the broiler.
Let the pie rest for a few minutes after baking so it firms up enough to cut clean, distinct slices.
Sweet potato version: use half sweet potato, half russet for the mash for a slightly sweeter, more colorful topping.
Vegetarian version: replace the beef with a mix of lentils and mushrooms, keeping the same cumin and olive seasoning.
Cheese-topped: sprinkle shredded cheese over the mashed potato before broiling for an extra golden, cheesy crust.
Refrigerate up to 4 days in an airtight container. Reheat individual portions in a 350°F oven or microwave until warmed through; the dish also freezes well, well wrapped, for up to 2 months.
Pastel de papa reflects Argentina's Spanish and Italian immigrant heritage, drawing on European shepherd's pie-style layering while incorporating distinctly Argentine touches like cumin, green olives and hard-boiled egg found across many of the country's savory pies and empanada fillings.
This usually means the beef filling was too wet -- simmer it longer until most of the liquid evaporates before layering on the mashed potato.
Yes, assemble the full pie a day ahead, cover and refrigerate, then bake straight from the fridge, adding about 10 extra minutes to the initial bake time.
Simply omit them -- the raisins add a traditional touch of sweetness found in many Argentine picadillo fillings, but the dish is just as good without them.
