Prepare the ingredients, they are the simplest: salt, pepper, red paprika and vegetable oil, and of course the liver.
Wash the liver well, cut off all the veins.
Add 1 teaspoon of salt, 1 teaspoon of black pepper and 2 teaspoons of red paprika to the vegetable oil.
Add the marinade to the liver and refrigerate for half an hour.
We lubricate the form with vegetable oil, I carefully scooped out the oil from the liver with a spoon and poured it over the form.
Distribute the liver in the form. It is better to cook in a large form, so that the liver does not lie on top of each other. Send to the preheated oven at 180 degrees with convection for 20 - 22 minutes. I checked after 20 minutes and left it for another 2 minutes. Be guided by your oven, but you do not need to keep it for more than 25 minutes, otherwise the liver will turn out dry.
Remove from the oven and serve immediately hot. I served it with mashed potatoes and fried onions.
The liver is very tender!
