Least Processed Pasta Sauces
Each product is ranked by its own Processing Score, lowest first. To keep the list from being one company's catalog, it shows at most two products from any one brand.

How are products scored?
Every product is evaluated using two independent scores. The Processing Score (lower is better) measures the degree of industrial processing based on ingredient analysis, including the presence of artificial additives, preservatives, and highly modified ingredients. The Nutrition Score (higher is better) rates overall nutritional quality, rewarding protein and fiber while penalizing excess sodium, added sugars, and saturated fat.
Products are assigned to one of four processing levels: Minimal (score ≤ 2.5), Processed (2.6 to 5.0), Highly Processed (5.1 to 8.0), and Ultra-Processed (above 8.0). Each product in the ranking is placed by its own Processing Score, not by its brand. Based on our analysis of 445K+ curated products from the USDA FoodData Central database.

Frequently Asked Questions
Is jarred pasta sauce ultra-processed?
Simple jarred sauces with tomatoes, olive oil, garlic, and herbs score low. Sauces that add sugar, soybean oil, and modified starches score much higher.
What is the healthiest pasta sauce?
In our analysis, the least processed pasta sauce options list whole tomatoes or crushed tomatoes as the first ingredient, use olive oil instead of soybean oil, and skip added sugar entirely. The sauces ranked here have the lowest processing scores in the category, spaghetti sauce and marinara included.
Why do some pasta sauces add sugar?
Sugar masks the acidity of lower-quality tomatoes. Sauces made from high-quality San Marzano or vine-ripened tomatoes have natural sweetness and do not need added sugar.
Is homemade sauce better than jarred?
Only if the jarred version contains additives. A high-quality jarred sauce with tomatoes, olive oil, garlic, salt, and basil is nutritionally equivalent to homemade.
