The BEST-EVER Fried Fish Sandwich | Spanish Bocadillo de Bacalao y Pisto

This Spanish bocadillo de bacalao y pisto is possibly the best-ever fried fish sandwich. It’s filled with flavors, easy to make, and done in just 30 minutes. Serve it next to a handful of chips and a couple of ice-cold beers or some chilled club soda for the best moment in your day.

The BEST-EVER Fried Fish Sandwich

To make this recipe, I used cod fillets I bought frozen and thawed out. However, you can also use the fresh stuff here, as well as any other type of firm white fish. Such as halibut, white sea bass, or even hake, which is known as merluza in Spain.

For the bread, I used small baguettes. You can use whatever type of bread you like. Just make sure it has a hard shell to it. That way, once you add all the ingredients, it doesn’t get mushy and break apart.

TIPS & TRICKS to Make this Recipe: You can make the pisto (ratatouille) and mayo aioli ahead of time. They will both hold for up to 3 to 4 days in the fridge in an airtight container.

    I am always impressed by the thickness of the cod fillets you use. Here, in Souuthern Andalucia, the cod I ca find is much thinner – where do you source the ones you use. Mant thanks.
