Making sugar free tomato pasta sauce is simple, with minimal ingredients and big flavor. The magic lies in the technique to make the sauce and using high quality tomatoes.
In this recipe I'm using San Marzano DOP tomatoes. These tomatoes grow in a specific southern Italian region (Agro Sarnese-Nocerino) where the soil is rich in volcanic minerals producing the sweetest, highest quality tomatoes.
I received a complimentary package of San Marzano tomatoes to try with this recipe and I will only buy authentic San Marzano tomatoes going forward because they make a huge difference in the recipe.

This sauce is vegan friendly and uses natural ingredients that are probably already in your pantry.
The list of ingredients is short, so using high quality and fresh ingredients is a must. The main ingredients that should be high quality are your tomatoes and your olive oil.
- San Marzano Tomatoes: These tomatoes are grown and canned in only 41 towns in Italy that are protected under the DOP, meaning that if the tomatoes are not from those regions, they can't use the San Marzano name. These tomatoes are exquisitely balanced with the right sweetness and tart flavors.
- Olive Oil: use a high quality extra virgin olive oil. Olive oil adds flavor and aroma and it's the base for a sweet sauce without the added sugars.
- Sweet Yellow Onion: We are using the natural sweet flavors in our ingredients to create a naturally sweet sauce. White onion will work too but yellow onions are my first choice in this recipe.
- Garlic: Fresh garlic is a must. Stir tear from garlic paste or pre crushed garlic for this recipe.
- Basil: Fresh basil leaves are the final touch for this recipe.
How to cook the sauce
The technique is the most important thing in this recipe. You need to have enough time to cook the sauce so the flavors develop.
Cooking the onions low and slow over 30 minutes, will develop the sweet flavor that we want in our sauce without adding white sugar to cut the acidity in the tomatoes.
In this recipe we are using high quality San Marzano tomatoes which are naturally sweet, will enhance the natural sweet taste of this sauce.
