Add the pasta to a large pot of salted boiling water. Cook per package directions for al dente. Reserve 1/4 cup of the water then drain pasta. Add a light drizzle of olive oil over the pasta so it doesn’t stick.
Heat the olive oil in a large skillet over medium to medium-high heat. Add pancetta, cook 7-9 minutes or until cirspy then remove from the skillet (leaving fat in the skillet).
Reduce heat to medium-low then add diced onion. Season with salt and pepper and cook 3-4 minutes until onions are tender.
Add minced garlic and crushed red pepper. Cook 1 minute stirring constantly so garlic doesn’t burn.
Pour in the vodka and cook 6-8 minutes over medium-low heat or until the vodka is reduced by about half.
Add crushed tomatoes. Simmer 10-12 minutes letting the sauce thicken.
Reduce heat to low, blend in heavy cream then slowly add parmesan cheese a little at a time until combined. Blend in parsley then season with salt and pepper to taste. Simmer 2-3 minutes letting the sauce come together.
Add the pasta stirring gently to blend well and completely coat the pasta. If the sauce is too thick add a splash of the reserved pasta water.
Serve right away topping with pancetta, extra parsley, fresh basil and parmesan cheese.
