Picadillo in Costa Rica means something finely chopped and cooked down in a pan — not the meat-and-raisin dish the word describes elsewhere. In Nicoya it is usually vegetable-led: chayote most often, sometimes green papaya or potato, bulked with beans and eaten folded into a tortilla.
It is the least glamorous thing on this site and probably the most representative. Blue Zone eating is not a parade of signature dishes — it is the same cheap, plant-heavy pan of something, most days, for decades.
The Ingredients
- 3 chayote, peeled, seeded and cut into 5mm dice
- 400g cooked black beans, drained (see our bean method)
- 200g sweetcorn kernels, fresh or frozen
- 1 onion, finely diced · 1 red pepper, finely diced
- 4 garlic cloves, minced
- 1 tsp ground cumin · 1 tsp dried oregano · ½ tsp smoked paprika
- 2 tbsp olive oil
- 1 large bunch coriander, stalks and leaves separated, both chopped
- 1 lime · salt and black pepper
- Corn tortillas, to serve
How to Make It
The whole character of a picadillo is in the cut — 5mm, consistent, so everything cooks at the same rate and a spoonful carries all of it at once. Chayote is slippery once peeled; keep your knuckles back.
Olive oil over medium, then the onion and pepper with a good pinch of salt for 8 minutes until soft and sweet. Add the garlic, coriander stalks, cumin, oregano and paprika and cook 1 minute more until fragrant.
Add the chayote and 100ml water, cover, and cook 12–15 minutes, stirring once or twice. It releases a lot of its own liquid — you want it tender with a slight bite, not collapsed.
Fold in the black beans and sweetcorn and cook uncovered 5 minutes, letting the remaining liquid cook off. Beans added early break up; added here they stay whole.
Off the heat, stir through most of the coriander leaves and a good squeeze of lime, then taste and correct the salt — it will need more than you expect. Serve with warm tortillas and the rest of the coriander on top.
