Ingredients (serves 1–2)
- 4–6 picorocos (Chilean barnacles)
- 100 g grated cheese (such as mozzarella or Parmesan)
- 1 clove garlic, finely chopped
- 2 tablespoons olive oil
- 1 teaspoon paprika
- Salt and pepper, to taste
- Fresh parsley, to garnish
Shopping for the ingredients
When you set out to make picorocos gratinados, look for freshly caught picorocos at a good fishmonger or at a weekly market. It is important to choose high-quality shellfish to guarantee the best possible flavour. The remaining ingredients, such as cheese and spices, are easy to find in any well-stocked supermarket. Be sure to use fresh herbs like parsley to give the dish that extra touch of refinement.
Preparing the dish
Begin by cleaning the picorocos carefully. Remove any loose bits of shell and rinse them thoroughly under running water so that no unwanted particles end up in the finished dish. Prepare the cheese and the spice mixture with care, cutting and measuring everything ahead of time to ensure an even coating when the barnacles are gratinated.
Step-by-step instructions
- Preheat the oven to 200°C.
- Heat the olive oil in a pan and add the chopped garlic, cooking until golden.
- Add the picorocos to the pan and sear briefly, then season with salt, pepper and paprika.
- Arrange the barnacles in an ovenproof dish and scatter the grated cheese over the top.
- Bake in the preheated oven for about 10–15 minutes, until the cheese is golden and bubbling.
- Garnish with fresh parsley and serve hot.
Gluten-free / lactose-free version
For a gluten-free and lactose-free version of picorocos gratinados, simply choose a suitable cheese. There are many delicious alternatives that contain no lactose yet still deliver plenty of flavour. Take care to check every spice and ingredient you use so as to avoid both gluten and lactose. That way, guests with food intolerances can enjoy this dish just as much as everyone else.
Tips for vegans and vegetarians
Although picorocos gratinados are traditionally made with seafood and cheese, vegans and vegetarians can create their own plant-based version. Replace the barnacles with pan-fried shallots or a medley of different vegetables. Instead of dairy cheese, use vegan cheese or nutritional yeast to mimic the savoury, cheesy note. This way, plant-based eaters can also enjoy this delicious combination of flavours.
More tips and tricks
To get the very best from your dish, pay close attention to the quality of the ingredients. Fresh picorocos make a clear difference to the taste. Play with the spices to create your own signature — perhaps a pinch of chilli powder for a little heat? The cooking time can also vary slightly depending on the size of the barnacles, so keep an eye on them while they are in the oven. A splash of the fresh, herby Pebre on the side is another lovely touch.
Adapting the recipe to your taste
A great recipe should adapt easily to your personal preferences. Feel free to experiment with additional herbs such as thyme or rosemary to add a new dimension to the dish. A scattering of toasted nuts can also provide an interesting crunch. The possibilities are endless, and a little experimentation makes cooking all the more enjoyable.
Ingredient substitutions
If you find yourself missing an ingredient, there is usually an excellent alternative to hand. Instead of mozzarella, you could use feta, which brings a more intense flavour. Likewise, olive oil can be swapped for sunflower or rapeseed oil. Be creative and use what you have to adjust the dish to your store cupboard — the same relaxed spirit that shines in Machas a la Parmesana, another beloved Chilean gratin.
Drink pairing ideas
Picorocos gratinados go beautifully with a refreshing white wine such as a Sauvignon Blanc, or a light beer. These drinks complement the salty aromas of the dish perfectly. A crisp rosé can be a wonderful choice too. For an alcohol-free option, try a sparkling mineral water with a squeeze of lemon, or round off the meal with a classic Pisco Sour.
Serving and presentation ideas
Presentation is an essential part of any successful dish. Serve the picorocos in their shells or in pretty individual gratin dishes to give the whole thing a rustic look. Garnish the barnacles with fresh herbs and perhaps a few slices of lemon for a splash of colour. An attractively arranged plate not only whets the appetite but also makes the cooking feel all the more rewarding.
A bit of history
Picorocos have their origins in the coastal regions of Chile, where they are harvested by local fishermen. In Chilean culture they are a symbol of the country’s abundant seafood cuisine. The preparation of picorocos gratinados goes back to old traditions in which fresh ingredients and local spices took centre stage. Today they are not only a much-loved dish but also a mark of Chile’s culinary heritage, celebrated across the wider world of Chilean cuisine.
