The water is heated in a saucepan with the milk, butter / oil and spices. The polenta is then sprinkled into this mixture. The polenta must be stirred until the mass is reasonably firm. The polenta mass is then spread in a buttered casserole dish.
The onion and garlic are chopped and fried in a pan. Cut the remaining vegetables and add them to the pan. Season with salt and pepper and cook for about 5 minutes. Then stir in the crème fraîche. Put the vegetables on the polenta, sprinkle the casserole with cheese. Bake the casserole in the oven at 180 ° hot air for about 20-25 minutes.
Tip:
If you like meat, you can theoretically also add ham / bacon.
