Garden Vegetable Lasagna

Heat the oven according to the complete lasagna recipe directions.

Prepare the mushroom-heavy vegetable filling and tomato sauce.

Cook the regular lasagna noodles according to the package directions and drain them well.

Prepare the béchamel by cooking the flour in the fat before slowly whisking in the milk.

Season the vegetable filling, tomato sauce, and béchamel separately before assembling.

Layer the noodles, vegetable filling, tomato sauce, béchamel, and cheese in a 9-by-13-inch baking dish.

Cover and bake until the lasagna is hot throughout.

Uncover near the end of baking so the top can brown.

Rest for at least 15 minutes before slicing.
