- 2.Bake at 350°F for 25 minutes.
- 3.Uncover for the last 5 minutes to re-crisp the top.
- 4.Verify 165°F at the center — lasagna centers are notorious cold spots.

Pro tip: Day-two lasagna outranks day-one — the layers set and the flavors merge. Worth the 25 minutes.
🌡️ Food safety
Dense layered dishes hide cold centers — verify 165°F in the middle with a thermometer.
❄️ From frozen: extend to about 60 min and check the center is fully hot before eating.
