Penne with shrimp and parmesan

PREPARATION:

1. Cook penne al dente in salted boiling water in a large saucepan. Before draining all the water, pour about 100 ml of water into a glass. The high content of starch in this water will then make the sauce thicker and silky. Return pasta to the saucepan.
2. Melt the butter in a large frying pan. Add finely chopped garlic and fry until fragrant for 2 minutes. Add red chili pepper flakes and shrimp, season with salt and pepper. Cook until shrimp turn pink, 2 minutes each side. Add parsley and stir. Set the shrimp aside on a plate.
3. Add spinach to the skillet and salt. Cook for 2 minutes over medium heat, stir, then add finely diced tomatoes, heavy cream, ¼ cup of pasta water, Parmesan, and cook for 5 minutes.
4. Add shrimp and boiled penne to the pan and stir until smooth.
5. Sprinkle Parmesan and finely chopped parsley on top and serve. Buon appetito!
