Soak dried porcini for about 20 minutes in 400 ml of lukewarm water. Peel and finely dice the shallots. Drain porcini, collect the liquid and measure 150 ml.
Heat olive oil in a pot. Sauté the diced shallots in it until translucent, turning them over. Add rice and sauté briefly. Gradually add porcini stock, broth and wine, stirring from time to time.
Always add the next portion of liquid only after the rice has absorbed the liquid. Cook for a total of 30-35 minutes.
Cut toast into small cubes. Peel onion and garlic and dice finely. Knead minced meat, egg, toast, onion, garlic, tomato paste, 50 g parmesan, salt and pepper. Form about 16 meatballs.
Heat oil in a frying pan, fry balls in it for about 10 minutes while turning and take them out.
Cut the tomatoes into large pieces. Fold crème fraîche, 50 g parmesan, porcini mushrooms and tomatoes into the risotto. Wash thyme, shake dry and pluck leaves from the stalks. Arrange risotto and meatballs on plates.
Garnish with thyme.
