How to Tell It's Done

until the cheese is bubbling and golden

Tips

Put things in the oven only once it's reached temperature, after the heating light has gone off: an oven that hasn't reached temperature changes baking times, and the bake burns outside or stays underbaked.
Spread cooled sauce on pizza: hot sauce softens the dough even before baking.

Common Mistakes

A gentle simmer, not a boil: a hard boil dries the food out and clouds it, a slow simmer cooks it evenly.
Check by the cue (until…), not just the clock: every oven bakes a little differently.

More Ways

Store-bought lasagna sheets don't need precooking: layer sheets, meat sauce and béchamel or cheese, repeat the layers and finish with béchamel and mozzarella on top.
In the egg version: in a greased pan, layers of meat with sauce (placed on matzo), beaten eggs poured over the last layer, baked at 180°C (355°F) for 35–40 minutes, until the bake is set and browned.
