Boil pasta according to package directions. Drain and set aside. Set aside 1/4 cup of the pasta water to be used later.
In a large pot (you can use the same pot you boiled the pasta in), heat olive oil on medium heat. Once oil is warm, add in minced garlic, 1 tsp of red pepper flakes and half of the basil. Once all ingredients start to sizzle (1-2 minutes), add in 2 tbsps of tomato paste and using a whisk, whisk together to incorporate it with the oil. Next add in 1 cup of heavy cream and 1/4 cup of pasta water. Whisk together. Finally add in remaining 1/2 cup of heavy cream and 7 tbsps of tomato paste. Whisk together until a smooth pink sauce forms. Allow sauce to simmer and boil for 5 minutes on medium heat, allowing the flavors to come together. Add in 1 tsp of red pepper flakes and remaining basil.
Perform a taste test at this point to see which spices you want to add in.
Add in pasta a little at a time, making sure to fold pasta into the sauce. Alternatively you can keep the sauce and pasta separate and put together while eating it!
