One of Spain’s BEST-KEPT Fish Recipes | Bacalao Encebollado de Córdoba
This Spanish Cod in Onion Sauce, known as Bacalao Encebollado de Córdoba, is what Spanish regional food is all about. We’re talking a ton of great flavors, simple everyday ingredients, and all done in about 30 minutes. Serve it next to some roasted potatoes and a bottle of Spanish white wine for a complete meal.
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 halibut, white sea bass, or even hake, which is known as merluza in Spain.
To make the onion sauce, I used homemade vegetable broth. You can also use chicken broth or even fish broth if you prefer. I also added some wine for depth of flavor. If wine is not your thing, just substitute it for any broth of your choice with a squeeze of lemon juice.
TIPS & TRICKS to Make this Recipe: It took me about 4 minutes per side to fully cook the fish. Of course, every pan and stovetop heats differently. So it may take you less or more. Just keep an eye on the fish to not overcook it.
