  1. The first step in this baked mackerel recipe is to grab the potatoes and onions, then clean, peel and cut them. Do the same with the red bell pepper, and remove the seeds. 
  1. Then, place them on a baking tray (with a dash of oil so they don’t stick), salt to taste, and cook in the oven at 180°C for 15 minutes. Stir once or twice so they cook evenly.
  1. Chop the garlic and the parsley. In a food processor, blender, or mixer put them together with the wine and the tablespoons of olive oil.
  1. Once the potatoes are almost cooked, take the tray out of the oven, place the mackerel fillets on top and add the mixture of garlic, parsley, and oil.

  1. For the final step, take the tray out of the oven, and the Spanish mackerel fillet is now ready to serve. As an optional step, you can put some fresh chopped parsley on top

Substitution of Ingredients

There are several changes you can make to the ingredients in this mackerel fish recipe. First, you can use other fish such as hake, tuna, barracuda, etc.

We also have listed some vegetables that are the accompaniment, but you can make your Spanish mackerel fillet without them.

You can skip the mix of garlic, parsley, oil, and wine, or just remove the wine (you should add a little more oil in that case).

But there are still more changes you can make, for example, there are different ways of cooking mackerel.

You can turn it into Spanish fried fish. In this case, take 2 eggs, beat them, and pass the fillets through there and then through breadcrumbs. 

Then you can fry them (for 7 minutes or until golden) and serve.

In that case, you would have a fried mackerel and you could avoid cooking the onions and potatoes (although they are the perfect accompaniment). 

You could use the garlic, parsley, and olive oil sauce as a seasoning (without the wine).
