Grate the cheese, chop the garlic and chop the spring onions and mushrooms into bite-sized pieces.
While the noodles are cooking, sauté the minced meat and season with salt and pepper.
Mix the cream with the gratin cheese and garlic. Then season to taste with salt, pepper and tomato paste.
With the exception of the already grated Gouda, the pasta, which has been cooked to the bite, is placed in a large baking dish with all the other ingredients and mixed well.
Finally, cover the casserole with the Gouda cheese and bake for about 30 minutes in an oven preheated to 200 ° C top / bottom heat until the desired degree of browning is achieved.
