Did you make this from scratch or pull it from the freezer like a hero on a Tuesday night? That changes things. A fresh lasagna (straight from assembly) can handle that 375°F covered-for-40 routine like a champ.
But if it’s frozen? Oh, buddy. Pop it in straight from the freezer—no thawing. Bake it covered at 375°F for an hour. Yes, a full hour. Then uncover and give it another 15 minutes. Patience, grasshopper. It’s worth it.
The “I Forgot to Defrost” Loophole
If you’re like me and never remember to thaw anything, here’s a pro tip: use a lower temp for longer. Try 350°F for 75 minutes covered, then 10 minutes uncovered. It’s slower, but it saves your lasagna from being a frozen brick in a hot pool of sauce.

And for the love of all that is cheesy, use an instant-read thermometer. Stick it in the center. You want 165°F or higher. No cold spots allowed.
