Preheat the oven to 350°F (175°C).

Cook the whole wheat lasagna noodles according to package directions; drain and set aside.

In a large skillet over medium heat, warm the olive oil. Add ground beef, garlic powder, oregano, salt, and pepper. Cook until beef is browned, breaking it into crumbles as it cooks.

Stir in the marinara sauce and let it simmer for 5 minutes.

Spread a thin layer of meat sauce on the bottom of a 9×13-inch baking dish. Layer 3 noodles on top of the sauce.

Sprinkle ⅓ of the mozzarella and Parmesan over the noodles. Repeat layers twice more, ending with cheese on top.

Cover the dish with foil and bake for 30 minutes. Remove the foil and bake an additional 20 minutes, or until the cheese bubbles and turns golden.

Let the lasagna rest for 10 minutes before slicing.
