the.com/lasagna al forno

means Baked lasagna layered with pasta sheets, sauce, cheese, and (usually) béchamel or ragù, then oven-finished until the top goes golden and bubbling — the ultimate Sunday-dinner slab.

from 'Lasagna' traces back to Latin 'lasanum' (a pot or chamber-pot vessel, borrowed from Greek 'lasanon' for a trivet or cooking stand) via Italian, where it came to mean the broad flat pasta sheet itself and then the dish built from it. 'Al forno' is simply Italian for 'from the oven' ('forno' coming from Latin 'furnus'), the phrase Italians add whenever a dish is finished baked rather than boiled or sauced on the stovetop — so the name literally just confirms: this is the pasta that went into the oven and came out a building.
