Cook the spaghetti in salted water as usual until al dente.
Put the tuna in a colander and drain. Mix the creme fraiche and the tuna in a cream. Season to taste with salt, pepper or paprika powder, depending on your taste. If you like, you can also add onion and garlic.
Add the cooked and drained pasta to the mixture and mix everything together well. Sprinkle cheese on top.
Place in the preheated oven at 180 ° C until the cheese has melted and browned.
Tip: Instead of the normal creme fraiche, the one with herbs and garlic can also be used.
If someone likes vegetables, they can have a bunch of fresh broccoli. Clean this, bring to the boil in salted water and cut into small pieces. Then also add to the creme fraiche / cream mixture.
