Start by making the pasta according to package. Boil water, add in salt and cook pasta until it is cooked to your liking.
Next, in a large pot or dutch oven over medium heat, add in the EVOO.
Then, add in the diced yellow onion and freshly minced garlic. Mix well for about 5 minutes or until onion starts to slightly brown in color.
Then, add in the entire tube of tomato paste. Mix well for about 5-7 minutes, or until the tomato paste deepens in color and starts to brown at the bottom.
Add in the chili flakes, salt, pepper and italian seasoning.
Next, pour in the vodka to deglaze the bottom of the pan. Scrape the bottom of the pan and mix well. Reduce heat to low.
Using a heatproof glass measuring cup, scoop about ¼ cup boiling water from the pasta pot and add that to the sauce pot, then immediately add in the heavy cream. Mix well.
Using a strainer, grab the cooked pasta and whatever pasta water comes with it, and add it into the sauce. Coat well and add in the parmesan cheese. Mix until pasta is fully incorporated into the sauce.
Serve pasta with more parmesan cheese and fresh basil.
