Step 1

Heat olive oil in a medium pot over medium heat.

Step 2

Add the onion and sauté until soft, about 3 minutes.

Step 3

Add the garlic, a pinch of salt and red pepper flakes, then cook for 1-2 minutes longer until the garlic is fragrant.

Step 4

Add the canned tomatoes, then use a wooden spoon to smash and break them into pieces.

Step 5

Add a bay leaf and tomato paste (if using), along with about 1/2 - 1 cup of water, depending on the consistency of your tomatoes and how thick you want your sauce.

Step 6

Cover the pot and let it simmer for 20 minutes.

Step 7

Taste and season with more salt and pepper as needed. If the sauce is too acidic or tastes bitter, add a small pinch of sugar to balance the flavors.

Step 8

Add fresh basil or parsley (if using) right before serving to preserve their flavor.
