To prepare the arrabbiata pasta sauce, first, you need to peel the tomatoes, then mash them with a fork. In case you have tomato puree home, you can skip this step.
Put the oil and the garlic into a pot and start to heat it on low heat.
After 1-2 minutes, add the chili or spicy pepper (you can add both, if you prefer your food to be really spicy).
Add the tomatoes or the tomato sauce.
Mix it all together. Leave it to cook for about 12-15 minutes on low heat under a lid.
Put water to boil for the pasta. Add the pasta and cook it all dente. This will require about 7 to 8 minutes.
Once the sauce is ready, add the parsley and mix it well.
The last step of the pasta all arrabbiata recipe, drain the pasta and mix it into the arrabbiata sauce.
