Bring a saucepan of water to the boil with a little salt. Cook your linguine pasta in it for 10 minutes (or for as long as the packet instructions say).
While the pasta is boiling, heat 1 tablespoon oil in a large frying pan on a medium heat.
Add the garlic and onion and sautée until soft.
Add in the mushrooms and cook until everything is nicely browned.
Either push the mushrooms onion and garlic to the sides of the frying pan, or transfer them to a separate plate while you cook the prawns.
Add the remaining tablespoon of olive oil to the pan and cook the prawns for a few minutes on each side.
Add the paprika and salt. Cook while occasionally stirring for a further few minutes.
Add the crème fraiche and milk. Bring to the boil and tip in the grated mozzarella cheese.
If you removed the mushrooms, onions and garlic then return them to the frying pan.
Add in the cooked linguine pasta as well.
Stir everything thoroughly for a further 2 minutes on low heat. Garnish with parsley and serve!
