So, to recap: 50-60 minutes at 375°F, covered for 45 minutes, then uncovered. Sauce must be loose. Rest for 15 minutes. That’s it. You’ve graduated from Lasagna Novice to Lasagna Master.
Go forth and bake! And if you mess it up? Just call it “deconstructed lasagna” and eat it with a spoon. It’s still delicious, and the noodles are definitely cooked. You’re welcome.
