We Graded Every Pasta Sauce A–F. Even Cult-Favorite Rao’s Only Tied.

Jarred sauce is already low-calorie and basically fat-free, so the grade comes down to two things you don’t see in the marketing: added sugar and sodium. We ran the most popular jars through the same 6-dimension Labelgrade, and the low-sugar sauces lead — but here’s the twist worth the hook. Cult-favorite Rao’s, the one the internet swears by, only ties at B- (71); its no-added-sugar reputation is real, but it didn’t translate into a runaway win, edged by Classico Tomato & Basil and Newman’s Own Organics Marinara. The sweeter jars — Prego, Bertolli — trail. And all jarred sauce runs sodium-heavy, which is exactly why even the best caps at B-.

The verdict

It’s a two-way tie at the top — Classico Tomato & Basil and Newman’s Own Organics Marinara, both B- (72) — nosing out cult-favorite Rao’s (71); Bertolli Tomato & Basil came last at C+ (67), separated on added sugar and sodium.

How we graded these

Each product is scored on six dimensions — protein density, ingredient quality, added sugar, sodium, fiber, and saturated fat — combined into a 0–100 score and a letter grade. Every number comes from the product’s own label, verified against USDA FoodData Central. The grade is absolute (relative to all packaged foods), which is why a whole category can land in the same band. See the full methodology. Last graded 2026-06-04.

Frequently Asked Questions

Which pasta sauce scored best?

Classico Tomato & Basil and Newman’s Own Organics Marinara tied for the top at B-, with Ragu Old World Traditional and the famous Rao’s Homemade Marinara a single point back at B- (71). The winners keep added sugar low without piling on sodium. See the ranked table above for the full order and each sauce’s weakest dimension.

Why did Bertolli Tomato & Basil score lowest?

The sweeter jars carry more added sugar, and added sugar is one of our six dimensions — so Bertolli and Prego trail the low-sugar sauces above them. At C+ it isn’t a fail; it’s just out-scored. And because all jarred sauce is sodium-heavy, even the leaders cap at B-. The grade reflects what’s actually in the jar, not the brand’s reputation.

Is jarred pasta sauce healthy?

Mostly, yes — it’s low-calorie and fat-free, so it’s a reasonable base for a meal. The two things to watch are added sugar and sodium, which is what separates the jars and why the whole category caps at B-. The no-added-sugar, lower-sodium sauces score best; the sweeter ones a few points lower. A B-to-C+ grade means "a solid pantry staple, just read the label."

How is the grade calculated?

Six dimensions — protein density, ingredient quality, added sugar, sodium, fiber, and saturated fat — into a 0–100 score and a letter grade, from each product’s own label, verified against USDA data. See our methodology page.
