Who makes Kirkland Signature Italian Sausage and Beef Lasagna, 3 lbs, 2-count?
As of July 5, 2026, evidence points to Request Foods, Inc. as the manufacturer of Kirkland Signature Italian Sausage and Beef Lasagna, 3 lbs, 2-count, but no tier 1–3 source names the link directly.
The common claim
What most answers say — and what the evidence supports
Food-media roundups widely name Zinetti Foods as the maker of Kirkland Signature frozen lasagna, but that answer describes the Canadian product: Zinetti Foods is a Surrey, British Columbia manufacturer that supplies Costco warehouses in Canada. For the US-sold Kirkland Signature Italian Sausage and Beef Lasagna, Costco's own product catalog points elsewhere — its manufacturer (mfName) field names Request Foods, Inc., a Holland, Michigan private-label frozen-entree co-packer whose core capabilities include lasagna. Because that catalog field can name a supplier-of-record rather than the physical plant, the attribution is graded probable; the two answers are market-specific rather than contradictory.
Evidence & sources
Every source is graded on the six-tier rubric and archived, so the citation holds even if the original moves or paywalls. The tier badge grades the source; the status grades our confidence in the maker.
Tier 4
Costco's product-detail page embeds catalog JSON whose manufacturer field, on the object titled 'Kirkland Signature Italian Sausage and Beef Lasagna, 3 lbs, 2-count', reads "mfName":"REQUEST FOODS INC" (verified in the 2025-10-23 Wayback capture; costco.com blocks automated fetch). This is the same catalog field class that correctly resolves Kirkland diapers (FIRST QUALITY) and batteries (DURACELL). Because mfName can name a supplier-of-record or brand-company intermediary rather than the physical plant, it grades probable, not confirmed.
Tier 4
Corroborates capability (not the Costco link): Request Foods' own site states 'Lasagna — One of our core strengths, making lasagna in any flavor or size you want, from single serve to party-size.' Request Foods, Inc. (Holland, MI) describes itself as a leading co-packer of private-label frozen prepared entrees for retail and club-store customers. Context for the mfName attribution; the page does not name Costco or Kirkland.
Tier 6
The prevailing food-media claim, addressed here as the Canadian answer: 'the company is the brand behind Kirkland's sought-after frozen lasagna: Zinetti Foods. Established in 1985, Zinetti Foods is a Canadian food manufacturer based in Surrey, British Columbia.' Documents Zinetti as a Canada-based Costco supplier — relevant to Costco Canada, whereas the US item's own Costco catalog names Request Foods. Tier 6 (food media).
