Follow my recipe on my blog for "Homemade Marinara Sauce".
Boil water and salt in a large pot.
Add the pasta and let it boil for 10-12 minutes. To test if it's cooked, pasta should cut easily.
Remove from heat and strain it. Keep it aside.
Heat the same pot and add marinara sauce. Bring it to a boil. Now add pasta and mix well.
Remove from heat and transfer into a serving bowl. Garnish with Parmesan (optional). Enjoy!
