Preheat the oven: Set your oven to 375°F (190°C) and line a loaf pan with parchment paper or lightly grease it.
Prepare the zucchini: Grate the zucchini using a box grater or food processor. Place the grated zucchini in a clean kitchen towel or paper towels and squeeze out as much moisture as possible.
Mix the ingredients: In a large mixing bowl, combine the ground turkey or beef, grated zucchini, breadcrumbs, Parmesan cheese, chopped onion, minced garlic, egg, milk, oregano, basil, salt, and pepper. Use your hands or a spoon to mix everything together until well combined.
Form the meatloaf: Transfer the mixture into the prepared loaf pan and press it down to evenly distribute.
Top with marinara sauce: Spoon the marinara sauce over the top of the meatloaf, spreading it evenly with a spoon.
Bake: Place the loaf pan in the preheated oven and bake for 45-55 minutes, or until the meatloaf is cooked through and the internal temperature reaches 160°F (71°C). If the top starts to brown too much, you can cover it with foil during the last 10 minutes of baking.
Let it rest: Once done, remove from the oven and let the meatloaf rest for about 10 minutes before slicing.
Serve: Slice and serve with your favorite sides like roasted vegetables or a fresh salad!
Enjoy your light and delicious zucchini meatloaf!
