HOW TO MAKE AUTHENTIC ITALIAN MARINARA SAUCE RECIPE
STEP 1
One small onion, two cloves of garlic, and six fresh oregano leaves are chopped and placed away as we prepare the other ingredients. Dried oregano can be used if fresh oregano is not available.

STEP 2
Pour 30 cc of extra virgin olive oil into a saucepan, add the minced onion, and lightly sauté the garlic for a few minutes over medium heat.

STEP 3
Add 800 g of smashed natural tomato, 150 g of tomato paste, and the oregano after the onion is clear.

STEP 4
Cook the sauce for about an hour on low heat, stirring often to prevent sticking. We want a thick, flavor-focused sauce to be the result, therefore we want it to cook slowly and the water in the tomato to evaporate.

STEP 5
After the sauce has finished cooking, we add a bit of salt and, if necessary, a little sugar to regulate the sauce’s sweetness, though we haven’t done so in this instance. Fresh basil leaves should be chopped, then added to the sauce and thoroughly combined.

STEP 6
After another 10 minutes of cooking, the marinara sauce would be ready to use. For consumption within a few days, put it in an airtight container or bowl.
