Bring a large pot of salted water to a boil. Once boiling, add the spaghetti and cook as per the package instructions. Reserve a cup of the pasta water.
Meanwhile, add a large drizzle of olive oil to a frying pan and heat over medium. Add in the anchovies and sauté for a minute.
Add in the garlic and sauté for with the anchovies for one minute.
Add in the cherry tomatoes and hot pepper and sauté together over low heat for about five minutes, until the pasta is ready cooking.
Once the pasta is ready, scoop it directly into the frying pan. Mix the pasta together with the tomatoes and anchovies sauce.
Add a ladleful of the pasta water if it is not saucy enough and cook over medium to high heat for one minute.
Add in a few basil leaves, ripping them up by hand, and serve.
