Very simple yet very tasty lasagna made with oven ready lasagna noodles
Traditional baked ziti relies on loose tubular pasta shapes that trap sauce differently than flat sheets, but restructuring a multi-layer casserole requires careful proportioning when altering yields. Halving this recipe for a smaller household means shifting from a standard 9x13-inch pan down to an 8x8-inch baking dish while reducing the baking temperature slightly to prevent scorching the edges. When scaling down quantities that use eggs as a binder in the ricotta layer, whisk a single medium egg thoroughly and measure out approximately half by volume rather than guessing. Maintaining the correct ratio of moisture-rich tomato sauce to dry starch ensures the pasta hydrates properly during the initial baking phase without leaving standing liquid upon slicing.
Swapping jarred spaghetti sauce for fresh plum tomatoes or using handmade pasta sheets instead of commercially dried oven-ready noodles introduces drastically different water content into the assembly. Preserved jarred sauces have been reduced and thickened industrially, whereas fresh purées release significant liquid as cell walls break down under heat. Compensating for fresh components requires simmering them beforehand to drive off excess moisture or adding a tablespoon of semolina flour to the cheese mixture to absorb wandering water. Without these adjustments, high-moisture additions will dilute the binding capability of the eggs and cause the layers to slide apart when portioned.
Covering the pan tightly with a double layer of heavy-duty aluminum foil traps steam effectively, allowing the oven-ready noodles to soften fully at 425 degrees Fahrenheit over the course of sixty minutes. Removing the foil during the final ten minutes allows the top layer of mozzarella and parmesan cheeses to brown and bubble into a golden crust. Allowing the casserole to rest sealed in its foil for ten minutes after baking lets the internal temperatures stabilize and the melted dairy proteins firm up, making clean squares possible without structural collapse.
