Spanish GARLIC Fish | One of Spain’s Most Iconic Fish Recipes
This Spanish garlic fish, known as bacalao al ajillo, is one of Spain’s most iconic dishes. It’s filled with flavors, easy to make, and all done in about 15 minutes using just one pan. Serve it as a tapas appetizer or even as a main course, next to some roasted potatoes and a garden salad.

To make this recipe, I used cod fillets I bought frozen and thawed out. You can also use fresh cod here, as well as any other type of firm white fish. Such as white seabass, tilapia, or even hake, which is known as merluza in Spain.

To make the garlic sauce, I used a mortar & pestle. If you don’t have one, you can also use a food processor or even a hand blender. Either way, make sure to make the garlic sauce before cooking the fish. As the olive oil will smooth out the strong flavors of the raw garlic in the meantime.

TIPS & TRICKS to Make this Recipe: It took me about 6 minutes (3 minutes per side) to fully cook the cod fillets. Of course every pan and fish fillet cooks differently. Just keep an eye on the fish to not overcook it.

this sounds delish, can’t wait to try. Do you know why the potassieum is high in this recipe? Cooking for someone on a low potassieum diet, Thanks, Tony Lyons
