Transport your guests to Spain with this deliciously savory spin on “Higadillos Salteados” served as a tapa atop slices of baguette.

Spain is famous for serving tapas at many establishments, from Sevilla to Barcelona. What constitutes Spanish tapas varies from region to region, but generally, it refers to a small portion of food.

Furthermore, Spaniards are well known for their ability to work with animal organs and transform them into something absolutely crave-worthy. From the thighs and breasts to the neck and organs, they celebrate all animal parts utilizing various cooking techniques, herbs, and spices. “Higadillos Salteados” is a traditional dish cooked in Spain, composed of chicken livers sauteéd in sherry and olive oil. Typically smoked paprika and crisped pancetta are also features of this dish.

Our variation is intentionally simplified in ingredients to celebrate the beauty of the liver. The liver is rich in taste, texture, and nutrients. Instead of masking it, we highlight it with the addition of caramelized onions and jammy peppers. Spoon this mixture over slices of baguette and garnish with ground pepper, flat-leaf parsley, and a drizzle of olive oil.


Julienning the Vegetables

The onions and peppers must be cut into julienne strips. Julienne strips are approximately 1/8 of an inch or 3 millimeters in width. Julienning the vegetables is important, as it allows them to caramelize and cook evenly. Still not sure how to achieve it? Check out this video.

Caramelizing the Onions - Slow and Low

For this dish, you will need to lightly caramelize the onions before adding the peppers. Caramelization occurs when the onions are cooked at a very low temperature and the natural sugars in the onions slowly draw out.

The key to caramelization is “slow and low.” In other words, cook the onions at a very low temperature over time. If you use a cast-iron skillet, it may only take 30-40 minutes at a low temperature to achieve a light caramelization. However, if you use a non-stick pan, the time may increase to 50-60 minutes.

If it takes longer to cook, do not increase the temperature; just wait. Keep the temperature of the stovetop at medium-low heat. Time is the key to achieve ideal caramelization. If you increase the heat, the moisture in the onions may draw out too quickly, causing them to burn before they develop that sweet onion jam flavor. Patience is key.

What Does Cooked Liver Look Like?

According to the United States Department of Agriculture, the internal temperature of all chicken parts should be 165 degrees Fahrenheit or 73 degrees Celsius. However, the appearance of doneness differs between chicken livers and other chicken parts.

When fully cooked, chicken thighs and breasts must appear white throughout while the juices run clear. Chicken livers, on the other hand, should not appear bloody or raw but may appear slightly pink in the center when fully cooked.

Overcooked chicken livers can be rubbery and texturally displeasing, so it is important not to overcook them.

Reheating and Storage

Once you have finished making the dish, the leftovers may be refrigerated and consumed for up to 3 to 4 days. When reheating, spoon the mixture into a saucepan on the stovetop at medium-low heat. Warning: do not use the microwave. If you use the microwave, you will end up with exploding liver pieces decorating your microwave walls.
