Colombian Cheese Soup with Potatoes and Cilantro

This Colombian-style sopa de queso is a comforting soup of tender potatoes, milk, fresh cheese, and cilantro, served hot as a light meal or a first course. Recipes vary by region and household; this version uses queso campesino when available and keeps the broth gently creamy rather than thick or heavy. It is different from changua, the Colombian milk-and-egg breakfast soup.

Ingredients

1½ lb (680 g) yellow potatoes, such as Yukon Gold, peeled if desired
1 tablespoon (15 g) unsalted butter
1 tablespoon (15 ml) neutral oil, such as sunflower or canola oil
½ cup (75 g) finely chopped white onion
1 cup (100 g) thinly sliced scallions, white and green parts separated
2 garlic cloves (6 g), finely chopped
4 cups (950 ml) low-sodium chicken or vegetable broth
½ teaspoon fine salt, plus more to taste
¼ teaspoon ground cumin, optional
¼ teaspoon freshly ground black pepper
2 cups (480 ml) whole milk, brought to room temperature if convenient
8 oz (225 g) queso campesino, crumbled or cut into small cubes
⅓ cup (10 g) chopped fresh cilantro, plus a little more for serving
1 tablespoon (15 ml) lime juice, optional, plus lime wedges for the table

Instructions

Prepare the ingredients, 18 minutes. Cut the potatoes into even ½-inch (1.25 cm) cubes so they cook at the same rate. Rinse them briefly if they are very starchy, then drain well. Chop the onion, scallions, and garlic, keeping the scallion greens apart from the whites. Crumble or cube the cheese and chop the cilantro. Having the cheese ready before you start makes it easier to add after the soup comes off the heat.
Soften the aromatics, 5 minutes. Set a heavy soup pot over medium heat and add the butter and oil. When the butter has melted, stir in the onion and the white parts of the scallions. Cook for about 3 minutes, stirring often, until softened but not browned. Add the garlic and optional cumin and stir for 30 seconds. If the garlic starts to color, lower the heat; browned garlic can make the broth taste bitter.
Simmer the potatoes, 17 minutes. Add the broth, diced potatoes, salt, and black pepper. Bring the liquid to a boil, then lower the heat to maintain a steady, gentle simmer. Partially cover the pot and cook for 15 to 17 minutes, stirring once or twice, until a knife slides into a potato cube easily. Avoid a hard boil, which can break the potatoes into ragged pieces and reduce the broth too quickly. If the cubes are not tender after 17 minutes, continue simmering for a few minutes and check again.
Make the broth creamy, 5 minutes. Use a potato masher to press a few cubes against the side of the pot, leaving most of the potatoes intact. This releases enough starch to give the soup a little body without needing flour or cream. Pour in the milk and bring the soup back to a gentle simmer over medium-low heat, stirring occasionally for about 5 minutes. Do not let it boil vigorously; milk can scorch on the bottom of the pot or separate at a rolling boil.
Add the cheese, 3 minutes. Turn off the heat and wait about 30 seconds, then stir in the queso campesino in two additions. Let the cheese sit in the hot soup for 2 to 3 minutes, stirring gently once or twice. Fresh queso campesino softens and becomes tender but may not melt into a completely smooth broth; that texture is normal. Taste before adding more salt, because the cheese and broth both contribute saltiness.
Finish and serve, 2 minutes. Stir in the scallion greens and cilantro. Add the optional lime juice a teaspoon at a time, tasting as you go; it should brighten the creamy broth, not make it sharply sour. Ladle into warm bowls and garnish with extra cilantro. Serve right away while the potatoes are tender and the cheese is soft.

Tips

Choose a fresh, mild cheese. Queso campesino is a Colombian fresh cheese with a mild, milky flavor and a texture that holds together in warm soup. It can be difficult to find outside Latin American groceries. Queso fresco is the most practical substitute and behaves similarly, though it may be saltier or softer. Taste the soup before seasoning further.
Keep the dairy below a boil. Once the milk is in the pot, use low or medium-low heat and stir across the bottom occasionally. A gentle simmer is enough to heat the soup through; boiling hard can cause a grainy texture or a scorched flavor.
Cut potatoes evenly and mash only a few. Small, similar-size cubes become tender together. Mashing a portion thickens the soup naturally, while leaving most of the cubes whole gives each bowl distinct pieces of potato. For a thinner soup, skip the mashing; for a thicker one, mash a few more cubes.
Season in stages. Low-sodium broth gives you more control, but queso campesino and queso fresco vary in salt. Start with the measured salt, then adjust after the cheese has softened. If the finished soup tastes rich or flat, a small squeeze of lime and fresh cilantro can bring the flavors into balance.

Serving Suggestions

Serve the soup in warmed bowls as a simple lunch or as the opening course of a larger meal. It pairs well with arepas, crusty bread, or plain rice for dipping and soaking up the broth. A small salad of tomato, avocado, and crisp lettuce gives the meal a fresh contrast; keep its dressing light so it does not compete with the cheese. Put lime wedges and extra cilantro on the table so everyone can adjust their own bowl.

For a more substantial spread, offer sliced avocado, grilled vegetables, or a plate of arepas alongside the soup. Add the arepas separately rather than stirring them into the pot: bread and corn cakes soften quickly in hot liquid, and keeping them on the side lets the soup retain its texture. The soup is filling enough to serve on its own, especially with a generous portion of potatoes and cheese.

Variations

Make it vegetarian. Use vegetable broth instead of chicken broth and check that the cheese is made with a vegetarian-friendly rennet if that matters to you. A mild vegetable broth keeps the potato and fresh-cheese flavors prominent; a strongly flavored broth can overwhelm them.

Use a different potato. Yellow or waxy potatoes hold their shape well and give the soup a creamy bite. Russet potatoes also work, but they break down more readily and make the broth thicker, especially if stirred often. If using russets, cut them evenly and mash only a small portion at the end.

Adjust the cheese texture. If queso campesino or queso fresco is unavailable, use a mild farmer cheese that is not heavily salted. A little low-moisture mozzarella can be added for a stretchier, more melted texture, but it is not a close flavor match and may form strings. Avoid adding a large amount of aged cheddar: its stronger flavor and oilier melt take the soup in a different direction.

Add a little heat or extra green flavor. Offer thinly sliced mild green chile or a pinch of red-pepper flakes at the table rather than cooking them into the whole pot. You can also add extra scallion greens or cilantro at the end. These are optional contemporary adjustments, not requirements for every Colombian version of sopa de queso.

Storage and Reheating

Cool the soup promptly and refrigerate it within 2 hours of cooking in a shallow, covered container. It keeps for 3 to 4 days in the refrigerator. The potatoes will absorb some liquid as the soup sits, and the cheese may firm up, so expect the texture to be thicker the next day. Stir in a splash of milk or broth while reheating if needed.

Warm individual portions in a saucepan over low to medium-low heat, stirring gently and frequently, or use a microwave-safe bowl in short intervals, stirring between each. Reheat leftovers to 165°F (74°C), the USDA FSIS safe temperature for leftovers; check the center with a food thermometer. Do not let the soup boil hard, even while reheating. Freezing is not ideal because the milk can separate and the potatoes can turn grainy after thawing. If you do freeze it, use an airtight freezer-safe container for up to 2 months and expect some texture change; thaw overnight in the refrigerator and stir well as it warms.

Frequently Asked Questions

What is Colombian cheese soup called?
It is commonly described as sopa de queso, or cheese soup. Recipes vary, and the name can refer to different regional or household preparations. This version combines potatoes, broth, milk, and fresh cheese. It is not the same dish as changua, which is typically a breakfast soup made with milk, water, eggs, and scallions.

Can I use queso fresco instead of queso campesino?
Yes. Crumble queso fresco or cut it into small cubes and stir it into the hot soup off the heat. The result will be very similar, although the cheese may be softer or saltier depending on the brand. Add extra salt only after tasting the finished broth.

Why did my cheese not melt smoothly?
Queso campesino and queso fresco are fresh cheeses that soften but generally keep some shape in hot liquid. Small crumbles distribute more evenly than large cubes, but a few visible soft pieces are expected. Forcing the soup to boil will not make this cheese melt smoothly and can damage the milk-based broth.

Can I make Colombian cheese soup ahead?
You can make it a day ahead, but the cheese and potatoes change the texture as they rest. For the best result, cook the potatoes in the broth, refrigerate the base promptly, and add the milk and cheese gently while reheating. If you have already added everything, warm it slowly and loosen it with a little extra broth or milk.

How can I make the soup thicker or thinner?
For a thicker bowl, mash more potato cubes against the side of the pot before adding the milk. For a thinner broth, leave the potatoes whole and stir in extra broth or milk a little at a time. Adjust salt and lime after changing the amount of liquid, since dilution can soften both flavors.
