Preheat your oven to 375°F.
Slice the zucchini lengthwise into thin strips using a mandoline or knife; set aside.
Dice the half medium onion and mince the garlic cloves.
In a skillet over medium heat, sauté the onion and garlic in a small amount of your preferred cooking spray or olive oil until translucent.
Add the lean ground turkey to the skillet and cook until browned, breaking it apart with a spatula.
Pour in the tomato sauce and stir to combine with the turkey. Allow the mixture to simmer for 5 minutes. Season with salt and pepper to taste.
Layer a baking dish with a few zucchini slices, then add a layer of the turkey tomato mixture, followed by dollops of low-fat ricotta cheese and a sprinkle of fresh basil.
Repeat the layering process until all components are used, finishing with a top layer of zucchini slices.
Sprinkle the grated Parmesan cheese on top.
Bake in the preheated oven for 20-25 minutes until the zucchini is tender and the lasagna is heated through.
Allow it to cool slightly before serving.
