Lasagna

Why This Lasagna Works

During cooking, the noodles, sauce, and cheese all share moisture and sort of settle into one solid piece instead of sliding around. The lasagna noodles start out a little firm, but as they bake between the beef sauce and the ricotta, they soak up some of the liquid and soften all the way through. That keeps the layers from feeling watery and helps the slices hold together.

In the skillet, the ground beef browns and firms up, then the marinara and spices coat the meat and thicken a bit as they simmer. In the bowl, the egg mixed into the ricotta is important. Once it goes in the oven, that egg sets and turns the ricotta from loose and grainy into a smooth, spreadable layer that stays in place.

In the oven, the mozzarella and Parmesan melt down into the noodles and sauce. As the lasagna rests after baking, everything tightens up slightly. The cheese cools a bit, the sauce stops bubbling, and the layers stay stacked when sliced instead of spilling out.

Mistakes To Avoid

Boiling the noodles until they are very soft instead of just tender makes them tear when layered. Once baked with sauce, those overcooked noodles turn mushy and the layers slide around instead of cutting into neat squares.

Skipping the step of simmering the beef with the marinara sauce leaves the meat and sauce separate. In the oven, the liquid doesn’t thicken around the meat, so the lasagna can come out watery with loose meat pockets instead of a cohesive filling.

Putting the lasagna straight into the oven without a thin layer of sauce on the bottom of the dish causes the bottom noodles to dry out. Those first noodles then bake into a hard sheet that sticks to the pan and stays chewy even when the rest is cooked.

Cutting into the lasagna right out of the oven gives it no time to set. The hot cheese and sauce are still very loose, so the layers collapse and run out, and each piece ends up more like a pile than a slice.
