Is jarred pasta sauce as healthy as homemade? The question deserves an honest answer rather than a marketing one: it depends which jar and which homemade sauce you're comparing. Homemade has real advantages. Full control over sodium and added sugar, the ability to use good extra-virgin olive oil in the quantity that actually helps with lycopene absorption, and no preservatives are genuine points in its favor — when the cook has the time and inclination to do it well.
Jarred sauce has its own advantages that homemade can't easily match. Consistency from batch to batch, real time savings on a weeknight when a from-scratch sauce simply isn't happening, and — in the case of a purpose-built sauce like Sturdy Sauce — nutritional engineering that would be genuinely difficult to replicate at home, like a deliberately balanced three-protein blend most home kitchens aren't set up to formulate.
Sodium and added sugar are usually where the real difference shows up, and that cuts both ways. A rushed homemade sauce, salted heavily to compensate for underripe tomatoes and a short cook time, can lose to a well-formulated jar. A great homemade sauce, made with care and good ingredients, can beat almost anything on a shelf. For scale: many mainstream jarred sauces run 400 to 500-plus milligrams of sodium per half-cup serving, while a homemade sauce salted to taste, rather than salted for shelf stability and flavor consistency across a mass-produced batch, often lands meaningfully lower. That gap is real and worth checking on a label — but it's a gap between specific products, not a law of nature that separates all jars from all stovetops.
The honest framing: the choice between jarred and homemade is mostly a trade of time for a specific set of nutritional trade-offs — not a simple homemade-always-wins story, and not a jarred-is-just-as-good story either. It depends on the jar.
