Heat your oven to 400°F and get ready to create something delicious.
02 -
Heat a large non-stick pan over medium-high heat. Toss in the diced onion and ground turkey, seasoning generously with salt and pepper. Cook for about 8-10 minutes, using a wooden spoon to break up the meat as it browns beautifully.
03 -
Pour in the marinara sauce and stir everything together until the turkey is completely coated. Let it simmer for another 2-3 minutes to meld those flavors.
04 -
While your turkey mixture is cooking, slice each zucchini lengthwise down the middle. Using a spoon, carefully scoop out the seeds and flesh from the center, leaving about 1/4 inch of zucchini wall to create perfect boats.
05 -
Arrange your zucchini boats cut-side up in a 9x13 inch baking dish. Generously spoon the turkey mixture into each boat, then sprinkle with Parmesan cheese if you're using it.
06 -
Cover the dish with aluminum foil and bake for 20-30 minutes, until the zucchini is tender and heated through, and any cheese has melted into golden perfection. Serve immediately while hot.
