Creamy Shrimp and Mushroom Pasta

There seems to be something missing from the recipe. The instructions mention adding more spices at the same time as the cheese and half-and-half, and the pictures definitely show at least something fresh and green added at that point, but the recipe only mentions the cheese and half-and-half, nothing else.

Ingredients :

2 tablespoons olive oil
1 pound fresh shrimp (10 big shrimp or 20 small shrimp) without shells, deveined
3 garlic cloves
dried basil
crushed red pepper flakes
paprika
8 oz mushrooms, thinly sliced
1 cup half and half
1/2 cup Parmesan cheese, shredded
3/4 cup Mozzarella cheese, shredded
cooked pasta water
8 oz fettuccine pasta (for gluten free version, use Tinkyada gluten free brown rice pasta)
