In a pan pour vegetable oil, heat. In oil throw finely chopped garlic and chopped chili pepper. Fry a minute, add onions, roughly chopped, and a sprig of rosemary. Fry the onions until Golden brown. Add to the onions thawed mushrooms, fry until Golden brown, season with salt and pepper. At this time, while fried mushrooms, wash the potatoes and boil in their skins in salted water. Boiled potatoes peeled and cut into slices. For filling beat eggs, add cream, grated cheese (leave some cheese for topping), salt and pepper, mix it all together. All! Collect our casserole:

In a heatproof glass shape on the bottom put the fried mushrooms.

Mushrooms - sliced mozzarella.

On mozzarella put potatoes (don't forget a little salt and pepper).

For potatoes pour the egg-cream-cheese filling. Sprinkle the left cheese.

Bake in preheated to 180 degrees. oven for 25 minutes. To the hot casserole you can put a piece of butter.

Serve immediately, while hot. Frozen mushrooms I always defrost, so there was less water in the pan and they are fried until Golden brown better. Mozzarella for casseroles and pizza take "Russian", lump, in taste it is the same as that which is sold in brine, but for the price am pleased.))) Rosemary bought in a package, is not always used fully, before I dried it, now freeze, wrapped in foil, from fresh frozen differs only in colour (become slightly darker).
