Let us begin making marinara sauce recipe by blanching the tomatoes. Bring a pot full of water to vigorous boil. Add the whole tomatoes along with a teaspoon of sugar. Boil for 5-7 minutes. Drain and let cool for sometime. Peel and set aside.
Heat 2 tablespoon olive oil in a deep pa. Add minced garlic and saute in high flame for 3-4 minutes. Add chopped onions and saute until it turns soft. Add chopped carrots and saute until it turns soft.
Add the blanched and peeled tomatoes. No need to chop the tomatoes. Mix well and cook in medium flame. You can use masher to mash the tomatoes here and there. Add sugar and salt as required. You can a dash of pepper powder if needed.
After 10 minutes the tomatoes will thicken and reduce wee bit.
Add dried oregano and basil (if using fresh basil leaves, that should be added towards the end).
Simmer the sauce for 15 minutes until it thickens. You may simmer for more time if you prefer a very thick marinara sauce.
Add very finely mint leaves and mix well. Simmer for 5-7 more minutes and remove from flame. Allow the marinara sauce to cool thoroughly and store in a clean jar. Keep refrigerated.
