Preheat your oven to 375°F (190°C).
Slice the zucchini lengthwise into thin strips using a mandoline or a sharp knife. Set aside.
In a skillet over medium heat, sauté the chopped onion and minced garlic until they are fragrant and translucent, about 2-3 minutes.
Add the lean ground turkey to the skillet. Cook until browned and fully cooked, breaking it up into small pieces. Season with salt and pepper.
Mix in half of the tomato sauce with the cooked turkey, allowing the flavors to meld for another 2 minutes. Remove the skillet from heat.
In a small bowl, combine the low-fat cottage cheese with a few torn basil leaves.
In a baking dish, spread a thin layer of the remaining tomato sauce on the bottom. Arrange a layer of zucchini slices over the sauce.
Spoon half of the turkey mixture over the zucchini, then dollop the cottage cheese mixture evenly. Sprinkle a light layer of low-fat mozzarella on top.
Repeat the layers with the remaining ingredients: zucchini slices, turkey-tomato mixture, cottage cheese, and finish with a topping of mozzarella and a few basil leaves.
Cover the dish with foil and bake for 25 minutes. Remove the foil and bake for an additional 10 minutes or until the cheese on top is slightly golden.
Allow the lasagna to rest for a few minutes before serving to let the flavors settle.
