In a medium sauce pot, add in your water and salt, then turn your stove to HIGH heat. Let water come to a boil.
Add in your pasta and let it cook as per the package instructions or desired softness.
While the pasta is cooking, in another medium sauce pot, turn your stove to MEDIUM heat, then add in your sausage.
Let the sausage cook and brown up for 5 minutes, then add in your garlic, chilli flakes, and tomato paste and stir until everything has been well combined.
Next, add in your pasta water and heavy cream and let everything come together. Turn the heat to low to simmer for about 5 minutes.
Once the sauce has thickened up, add in your pasta, basil, parmesan and fresh black pepper. Let the sauce coat the pasta for about 3-5 minutes.
Serve and enjoy!
