The Hidden Sweetness in Your Spaghetti Sauce
For many, a jar of pre-made spaghetti sauce is a convenient weeknight staple. However, most consumers are unaware of the wide variation in sugar content among different brands and products. While tomatoes naturally contain some sugar, a significant portion in many sauces comes from added sweeteners. These added sugars are used by manufacturers to balance the acidity of tomatoes and appeal to a sweeter palate, often at the expense of a well-balanced flavor profile. The total sugar count can be startlingly high, making it essential to scrutinize labels, especially if you are managing blood sugar levels or simply trying to reduce your overall sugar intake.
Why Sauces Can Be So Sugary
Several factors contribute to the high sugar levels found in some store-bought sauces. Understanding these reasons can help you shop more mindfully.
- Balancing Acidity: Tomatoes are naturally acidic, and manufacturers often add sugar to counteract this tartness, creating a smoother, more palatable flavor profile that appeals to a wider audience. This is a common shortcut to avoid longer, more expensive cooking processes that would naturally mellow the acidity.
- Ingredient Quality: Cheaper sauces may use lower-quality, less-ripe tomatoes, which require more added sugar to compensate for a lack of natural sweetness. Higher-end brands often rely on premium, vine-ripened tomatoes that provide ample natural sweetness, requiring little to no added sugar.
- Flavor Profile: Some sauces are simply formulated to be sweeter. For example, brands like Prego are known for a sweeter flavor that appeals to American tastes, with some versions containing significant amounts of added sugar.
- Thickening Agents: Some brands use tomato paste as a base, which can concentrate both natural and added sugars. Others might add high-fructose corn syrup, a cheap and potent sweetener, to achieve a desired sweetness and texture.
High-Sugar Spaghetti Sauces
When analyzing store-bought options, it becomes clear that some brands stand out for their particularly high sugar content. Based on recent nutritional reviews, here are some examples of sauces with high reported sugar levels (note that product formulations can change over time):
- Prego Farmers' Market Classic Marinara: This sauce was identified in a 2025 review as a top contender for the most sugar, with a reported 14 grams per ½-cup serving.
- Victoria Marinara Sauce: Another brand cited in the same review, this sauce came in with 13 grams of sugar per serving, a surprising figure for a premium brand.
- Ragu Old World Style Traditional: A popular and affordable choice, this sauce has been reported to contain up to 12 grams of sugar per serving.
- Bertolli Tomato & Basil Sauce: While a familiar favorite, some versions of this sauce contain high levels of sugar, with some reports noting as much as 11-12 grams per serving.
- Prego Traditional Italian Sauce: A mainstay in many homes, this traditional sauce has been reported to have 10 grams of sugar per serving, contributing to its sweet flavor.
Lower-Sugar and No-Added-Sugar Alternatives
For those seeking a healthier, less sugary option, several brands offer sauces with little to no added sugar. When selecting a healthier sauce, prioritize brands that use high-quality, naturally sweet tomatoes and avoid unnecessary additives.
- Rao's Homemade Marinara: Often praised by chefs and dietitians, Rao's sauces are known for their high-quality ingredients and have zero added sugar. The natural sweetness comes entirely from the tomatoes and onions. This makes it a popular choice for keto and low-carb diets.
- Barilla Marinara: Some versions of Barilla's marinara sauces contain no added sugar, making it a reliable and widely available option for those watching their sugar intake.

How to Choose a Healthy Sauce
Making a healthy spaghetti sauce choice doesn't have to be complicated. By following a few key steps, you can avoid unnecessary sugar and focus on more nutritious options.
- Read the "Added Sugars" Line: The nutrition facts panel is your most important tool. Look at the "Includes Added Sugars" line under "Total Sugars." The goal is to find a sauce with 0 grams of added sugar.
- Check the Ingredients List: Ingredients are listed in descending order by weight. If sugar or high fructose corn syrup is high on the list, the sauce will be high in added sugar. A good quality sauce should have tomatoes, olive oil, vegetables, and seasonings listed first.
- Choose Organic: Organic sauces, such as those from Muir Glen, often prioritize high-quality ingredients and avoid added sugars.
- Opt for Premium Brands: Brands like Rao's often have a higher price point but reflect the cost of using better quality ingredients and traditional cooking methods that don't rely on sugar to mask flavors.
- Make It at Home: For complete control, the best option is to make your own sauce from scratch. It's often simpler than you think and guarantees no hidden ingredients. You can use quality canned tomatoes and add herbs and spices to taste. A pinch of sugar is sometimes used to balance acidity, but you can control the amount or skip it entirely.
Conclusion
For those on a nutrition diet, the seemingly harmless spaghetti sauce can be a major source of hidden sugars. Brands like Prego Farmers' Market and Victoria have been flagged for their high sugar content, while options from Rao's, Barilla, and Newman's Own offer better alternatives with little to no added sugar. By learning to read food labels for the "added sugar" line and ingredient list, you can make informed decisions that support your health goals. Whether you choose a premium store-bought sauce or opt for a simple homemade version, taking control of your ingredients is key to a healthier meal.
