Equipment You’ll Need

• Large pot or Dutch oven
• Cutting board
• Chef’s knife
• Vegetable peeler
• Wooden spoon or spatula
• Potato masher or fork
• Ladle

Ingredients

• 2 tablespoons achiote oil (or 2 tbsp neutral oil mixed with 1 tsp annatto powder)
• 1 large white onion, finely chopped
• 4 cloves garlic, minced
• 2 pounds (about 6 medium) Yukon Gold or other starchy potatoes, peeled and diced into 1-inch cubes
• 6 cups vegetable broth or water
• 1 cup whole milk or half-and-half
• 8 ounces queso fresco or mild feta, crumbled or cubed
• 1/2 cup chopped fresh cilantro
• Salt and freshly ground black pepper to taste
• For garnish: Sliced avocado, hard-boiled eggs (quartered), chopped scallions, and aji hot sauce

Instructions

1. Heat the achiote oil in a large pot or Dutch oven over medium heat. The oil should have a vibrant orange-red hue. Add the chopped white onion and cook until softened and translucent, about 5-7 minutes.
2. Stir in the minced garlic and cook for another minute until fragrant, being careful not to let it burn.
3. Add the diced potatoes and vegetable broth to the pot. Season generously with salt and pepper. Bring the mixture to a boil, then reduce the heat to a gentle simmer.
4. Cover the pot and let the soup simmer for 20-25 minutes, or until the potatoes are very tender and easily pierced with a fork.
5. Once the potatoes are cooked, use a potato masher or the back of a wooden spoon to gently mash about half of the potatoes directly in the pot. This is the key step to creating the soup’s signature creamy, thick consistency without using any flour or cornstarch.
6. Reduce the heat to low. Slowly stir in the milk, followed by the crumbled queso fresco and chopped cilantro. Continue to stir gently until the cheese is slightly melted and incorporated into the soup. Do not let the soup boil after adding the milk, as it can cause it to curdle.
7. Taste the soup and adjust the seasoning with more salt and pepper if needed.
8. Ladle the hot soup into bowls. Garnish generously with slices of fresh avocado, quartered hard-boiled eggs, a sprinkle of chopped scallions, and a drizzle of aji hot sauce, if desired. Serve immediately.

Expert Cooking Tips

• The Right Potato is Key: Use a starchy potato like Yukon Gold, Russet, or Papa Chola if you can find it. These varieties break down beautifully, creating the natural creamy base that is essential for authentic Locro de Papa.
• Don’t Skip the Achiote: Achiote (annatto) provides the soup’s characteristic golden color and a subtle, earthy, peppery flavor. If you can’t find achiote oil, you can make your own by gently heating neutral oil with annatto seeds and straining, or simply mix annatto powder into your cooking oil.
• Mash with Intention: The goal is not a perfectly smooth purée. You want a mix of textures—a creamy base with tender chunks of potato still intact. Mash gently and stop when you’ve reached a pleasing consistency.
• Low and Slow with Dairy: When adding the milk and cheese, keep the heat on low. Boiling the soup at this stage can cause the milk to curdle and the cheese to become tough and stringy. Gentle heat is your friend.

Substitutions and Variations

For the cheese, if queso fresco is unavailable, you can use Monterey Jack, a mild white cheddar, or even a mix of mozzarella and mild feta for a similar salty tang. For a dairy-free or vegan version, substitute the whole milk with an unsweetened, creamy plant-based milk like oat or cashew milk, and use a vegan cheese that melts well. For the achiote oil, a mix of 1/2 teaspoon of turmeric and 1/2 teaspoon of sweet paprika can be used to approximate the color, though the unique flavor will be missing.

Common Mistakes to Avoid

A common mistake is using waxy potatoes (like red potatoes), which hold their shape and won’t break down enough to thicken the soup naturally. Another pitfall is boiling the soup after adding the dairy, which can result in a curdled texture. Finally, don’t underestimate the importance of the garnishes. Serving Locro de Papa without avocado and aji is like serving a burger without the bun—the toppings are an integral part of the complete flavor experience.

Serving Suggestions

Serve Locro de Papa hot, ladled into deep bowls. The traditional garnishes are non-negotiable for the full experience: creamy sliced avocado, rich quartered hard-boiled eggs, and a sprinkle of fresh scallions or cilantro. A side of Ecuadorian aji criollo (hot sauce) adds a welcome spicy kick. For an even heartier meal, it’s often served with a side of toasted corn (cancha) or a piece of corn on the cob (choclo).

Storage and Reheating Tips

Store leftover Locro de Papa in an airtight container in the refrigerator for up to 4 days. The soup will thicken considerably as it cools. To reheat, gently warm it on the stovetop over low heat, adding a splash of milk or broth to thin it out to your desired consistency. Avoid boiling. Freezing is generally not recommended as the texture of the potatoes and the dairy can become grainy upon thawing.

Frequently Asked Questions

What is achiote and where can I find it?

Achiote, also known as annatto, comes from the seeds of the achiote tree. It has a mild, peppery, and slightly earthy flavor and imparts a beautiful golden-orange color to foods. You can find achiote seeds, paste, or infused oil in the international aisle of most large supermarkets or at any Latin American grocery store.

Can I make this soup vegan?

Yes, absolutely. To make a vegan version, use a creamy, unsweetened plant-based milk like full-fat oat milk or cashew milk instead of dairy milk. For the cheese, use your favorite brand of vegan feta or mozzarella shreds. Omit the hard-boiled egg garnish or replace it with roasted chickpeas for a protein boost.

My soup isn’t thick enough. What can I do?

If your soup isn’t as thick as you’d like, the easiest solution is to simply mash a few more of the cooked potatoes in the pot. You can also let it simmer gently (before adding the dairy) for a little longer with the lid off to allow some of the liquid to evaporate and concentrate the flavors.
