❓ FAQs
Can I use imitation crab in seafood lasagna?
Yes, imitation crab is a budget-friendly alternative that works well, though real lump crab adds better texture and flavor.

Medium to large shrimp (31/40 count) work best. Choose wild-caught if possible for better taste. Learn more about shrimp types for added insight.

Absolutely. Assemble the lasagna, cover tightly, and refrigerate for up to 24 hours before baking. Or freeze it for up to 2 months.
