Season the meat with salt and pepper and fry it in a pan in a little oil.
Meanwhile, cut the large onion and the beefsteak tomatoes into approx. 1 cm thick slices. Mix the cream cheese and the grainy cream cheese with the broth and set aside.
First put the raw pasta in a baking dish. Spread the fried meat and fresh basil leaves on top. Everything with the tomato and onion slices, ideally placed alternately, cover and pour the cream cheese mixture over them. Season with salt and pepper and cover with gratin cheese if you like.
Place in the oven at 180 ° C for approx. 30 minutes.
