Grease a baking sheet or cover with baking paper. Cut the tomatoes into slices.
Place the steaks on the tray, cover generously with tomato slices, fried onions and cheese. Mix the sauces with the crème fraîche and the pressed garlic and spread over the meat.
Preheat the oven to 200 ° C (convection) and cook for about 30 - 40 minutes. Rice and baguette go well with it.
