Score the tomatoes and blanch them by boiling in a covered pan for 5 mins and remove the skin.
Also, remove the cores and transfer to a blending jar and blend. If you prefer a smooth sauce, process until smooth.
Into a sauce pan on medium heat, pour olive oil followed by finely minced onion and minced garlic. Cook until the raw smell disappears.
Mix in tomato paste. Fry for 2 minutes.
Pour the pureed tomatoes, salt, pepper, dried basil, oregano, parsley and combine.
Add ½ - ¾ cup hot water and chili flakes to taste. Cover and simmer on low flame for 15 - 20 mins.
Add 1 tsp or more sugar to balance the acidity of the tomatoes. Switch off the flame.
Add ¼ cup Parmesan cheese (optional) and mix.
Best ever Marinara sauce is ready to use on pasta, pizza or as a dip. Enjoy!!
