Once it’s cold, wrap your pan tightly in two layers of plastic wrap. Then wrap it in a layer of heavy-duty aluminum foil. Smush it down so no air gets in. Air is the enemy of freezer food—it causes freezer burn, which tastes like disappointment.
Write the date on the foil with a Sharpie. Yes, you will forget. “Lasagna? That looks like ancient history.” Trust me, a label saves your sanity. It stays good for about three months. After that, it’s still safe, but the noodles get a little sad.
You can also assemble it in a smaller pan, or even in foil loaf pans for single servings. Mini lasagnas for mini victories.
