📝 About This Recipe

Hailing from the volcanic city of Arequipa, this Pastel de Papa is a masterpiece of Andean comfort food. Unlike a shepherd's pie, this version features layers of tender sliced potatoes bound together by a rich, savory custard and melted Queso Paria. It is the quintessential companion to Rocoto Relleno, offering a creamy, salty, and slightly anise-scented contrast that defines Southern Peruvian gastronomy.

🥗 Ingredients

The Potato Base

  • 1.5 kg Yukon Gold or Canchán potatoes (peeled and sliced into 1/4 inch rounds)
  • 1 tablespoon Fine sea salt (for boiling water)

The Cheese and Binding

  • 500 g Queso Paria or Muenster cheese (sliced or coarsely grated)
  • 50 g Unsalted butter (cold, cut into small cubes)
  • 1 teaspoon Anise seeds (toasted slightly to release aroma)

The Custard Royal

  • 1.5 cups Evaporated milk (essential for the authentic creamy texture)
  • 1/2 cup Whole milk
  • 3 pieces Large eggs (at room temperature)
  • 1 teaspoon Salt (adjust to taste)
  • 1/2 teaspoon Ground white pepper

👨‍🍳 Instructions

  1. 1

    Preheat your oven to 375°F (190°C). Generously grease a 9x13 inch ceramic or glass baking dish with butter.

  2. 2

    In a large pot of salted boiling water, parboil the potato slices for about 5-7 minutes. They should be slightly tender but still hold their shape firmly. Drain and let them air dry for a few minutes.

  3. 3

    In a medium mixing bowl, whisk together the evaporated milk, whole milk, eggs, salt, and white pepper until completely homogenous and slightly frothy.

  4. 4

    Begin layering by placing a single layer of parboiled potatoes at the bottom of the prepared baking dish, overlapping them slightly like shingles.

  5. 5

    Distribute a third of the cheese slices evenly over the potato layer. Sprinkle a pinch of the toasted anise seeds and dot with a few small cubes of butter.

  6. 6

    Repeat the layering process (potatoes, cheese, anise, butter) two more times until all ingredients are used, finishing with a generous layer of cheese on top.

  7. 7

    Slowly pour the milk and egg custard mixture over the assembled layers. Gently shake the dish or use a knife to poke small gaps so the liquid penetrates all the way to the bottom.

  8. 8

    Cover the dish tightly with aluminum foil. This allows the potatoes to steam and soften perfectly before the top browns.

  9. 9

    Bake in the center of the oven for 30 minutes.

  10. 10

    Remove the foil and continue baking for another 15-20 minutes, or until the top is deeply golden brown and the custard has set.

  11. 11

    Turn on the broiler for the last 2 minutes if you prefer a crispier, darker cheese crust.

  12. 12

    Crucial Step: Remove from the oven and let the Pastel de Papa rest for at least 15 minutes before slicing. This allows the layers to compress and the cheese to stabilize.

💡 Chef's Tips

Use starchy potatoes like Yukon Gold; they absorb the custard much better than waxy red potatoes. Do not skip the anise seeds; they provide the signature 'Arequipeño' flavor profile that distinguishes this dish. If you cannot find Peruvian Queso Paria, a mix of Muenster and a little Feta provides the right balance of melt and salt. Ensure the evaporated milk is used rather than just regular milk for a richer, more authentic 'crema'. Parboiling the potatoes ensures even cooking; skipping this often leads to crunchy centers in the middle of the cake.

🍽️ Serving Suggestions

Serve alongside a spicy Rocoto Relleno (stuffed pepper) for the ultimate Peruvian feast. Pair with a glass of Chicha Morada (purple corn drink) to balance the richness of the cheese. Accompany with a simple 'Sarsa Criolla' (marinated red onions) to add a bright acidity to the palate. Works beautifully as a side dish for roasted chicken or grilled alpaca steaks. Enjoy warm, though leftovers are surprisingly delicious when pan-fried the next morning.
