Fish with CREAMY Garlic Potatoes | One of Spain’s BEST-KEPT Recipes

This fish with creamy garlic potatoes, known as bacalao con patatas alioli, is one of Spain’s most underrated fish recipes. We’re talking a ton of flavors, simple everyday ingredients, and all done in about 30 minutes. Serve it next to a crunchy baguette and a bottle of Spanish white wine for a fabulous meal.

Fish with CREAMY Garlic Potatoes

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

For the potatoes, it’s important to use potatoes that are a bit more waxy than starchy. As they hold their shape better when being boiled. I used new potatoes, but you can also use yukon golds, red potatoes, or even golden delight.

TIPS & TRICKS to Make this Recipe: It took me about 4 minutes per side on a medium heat to fully cook the fish fillets. Of course every pan and stovetop heats differently. So it might take you less or more. Just keep an eye on the fish to not overcook it. The creamy garlic potatoes can be made ahead of time. They will hold for up to 3 to 4 days in the fridge.
