Ovens are liars, I swear. They say they’re 375°F but they’re actually 400°F or 350°F. Get an oven thermometer. They cost, like, five bucks. Stick it on the rack next to your lasagna. It’s the only way to know who’s telling the truth in that hot box.

If your oven runs hot, drop the temp to 350°F. If it runs cold, bump it to 385°F. You’re the boss. The oven just works for you.
