Usually mackerel is not baked whole, but is divided into pieces and even more often salted or smoked. But this recipe will please all household members and maybe even children.
Housewives will be even more delighted, because they will no longer have to spend hours at the stove - 5 minutes is enough.
The fish needs to be cleaned, the head and fins removed, and the belly washed after removing the entrails.
You can divide it along the spine into two parts, remove the spine and rib bones, and then you will get a fillet.
Now we prepare the marinade. To do this, mix the ketchup and mayonnaise, mix the spices with vegetable oil, add lemon juice and mix together.
Next, place the fish in a baking dish, pour in the marinade, preheat the oven to 220 degrees and put the fish in the oven.
In exactly 5 minutes it will be ready and can be served with rice or vegetables.
Bon appetit!
