Your oven is not the same as mine. It’s a fickle, moody appliance that runs hot or cold depending on its mood (or maybe just the wiring). Always start checking at the minimum time, and don’t be afraid to add 10 minutes if it feels right. Your lasagna is like a teenager—it needs love, attention, and a little tough love in the form of patience.
So, the next time you ask, “How long do I cook my lasagna?” remember this: 45 to 50 minutes at 375°F, covered then uncovered, is your safe harbor. After that, trust your eyes, your knife, and that beautiful bubbling sound. And if all else fails? Invite someone who’s better at waiting than you. I’m sure they’ll appreciate the burnt cheese bits as “extra crispy.”
