From offal you can cook a lot of tasty and healthy dishes. One of them is a liver soufflé with mushrooms and onions, baked in the oven. This recipe is good for both a festive table and daily menu. Due to the fact that the soufflé contains kefir, the appetizer is especially tender and resembles a pate in consistency. In addition, the specific taste of the liver becomes less pronounced. Therefore, this soufflé will appeal to even those who are not a fan of liver dishes. Instead of mushrooms, you can use browned carrots, sweet peppers, pumpkin, or eggplants for the filling.
