Lightly pepper and salt the chicken breasts and place in an ovenproof dish.
Roast the onion and garlic in the olive oil, add the tomato paste and pour in water (approx. 500 ml), so that a rather thick sauce is formed. Simmer until the onions are tender.
Add the cream and season with salt, pepper, sugar, balsamic vinegar and paprika powder. Finally add the diced paprika and herbs.
Let the sauce cool and pour over the meat. Cut the mozzarella into slices and place on top. Cook in a preheated oven at 220 ° C for about 35 minutes.
We ate rice with it. But I can also imagine spaetzle, noodles or simply baguettes.
