Step 1

Preheat oven to 375 degrees. Spray a 12 by 8-inch baking dish with non-stick cooking spray.

Step 2

Heat a 12-inch non-stick skillet over medium-high heat. Crumble in beef and cook and break up beef until cooked through.

Step 3

Remove from heat and stir in marinara sauce and vegetable broth (I like to swish the vegetable broth around in the empty jar of marinara sauce to remove any excess, totally optional).

Step 4

To assemble lasagna, spread 1/3 of the marinara sauce (about 1 1/2 cups) into bottom of baking dish. Top with 3 uncooked lasagna noodles.

Step 5

Spread 1/2 of the ricotta over the noodles using the back of a spoon. Top evenly with 1/2 of the mozzarella (1 cup) and 1/2 of the parmesan (1/4 cup). Top with another 1/3 of the sauce.

Step 6

Add 3 more uncooked lasagna noodles then spread evenly with with remaining 1/2 of the ricotta. Pour and spread over last 1/3 of the sauce. Top with remaining 1/2 of the mozzarella and parmesan.

Step 7

Cover tightly with foil (you can grease first if the top of the lasagna will be touching the foil so cheese doesn't stick), bake 35 minutes.

Step 8

Remove foil then continue to bake uncovered 10 minutes, or until lasagna is just tender (not soggy. There will seem to be a little liquid on the sides still). Let rest 5 minutes before slicing. Garnish with fresh basil or parsley if desired.
