Quick answer
Amy's (Level 2-3) is meaningfully less processed than Stouffer's (Level 4). The gap is not subtle: Amy's lasagna has about 20 organic ingredients; Stouffer's has 40+ including modified food starch, autolyzed yeast extract, and soy protein concentrate. Amy's avoids the industrial additives that define ultra-processing. The tradeoff is price, Amy's costs roughly twice as much per serving.

Frequently asked questions
Is Amy's really less processed than Stouffer's?
Yes, significantly. Amy's (Level 2-3) uses organic whole food ingredients with shorter ingredient lists and no modified starches, autolyzed yeast, or soy protein concentrate. Stouffer's (Level 4) relies on these industrial ingredients to achieve taste, texture, and cost efficiency at scale. The processing gap is among the largest in the frozen meal category.
Why is Amy's more expensive?
Amy's uses organic ingredients, real cheese, and traditional cooking methods that cost more than Stouffer's industrial alternatives. Stouffer's replaces slow-simmered stocks with autolyzed yeast extract, real cheese with soy protein concentrate, and natural thickening with modified food starch. Each substitution reduces cost but increases processing level.
