Ingredients (Serves 3–4)

3 medium zucchini, trimmed and halved lengthwise
24–26 ounce jar tomato basil marinara, divided
1 tablespoon olive oil
1 pound lean ground turkey or beef
⅓ cup diced onion
1 teaspoon minced garlic
⅓ cup chopped red bell pepper
½ cup chopped cremini (brown button) mushrooms
¼ cup chopped fresh Italian parsley
1 teaspoon Italian seasoning
½ teaspoon salt
Freshly ground black pepper, to taste
¼ teaspoon crushed red pepper flakes, optional
1 ½ cups shredded part-skim mozzarella cheese
¼ cup shaved or shredded Parmesan cheese
2 tablespoons Italian-style panko bread crumbs

Instructions

Prepare the Zucchini

Preheat oven to 375°F (190°C).
Trim zucchini ends and slice lengthwise. Scoop out the flesh with a spoon, chop it, and set aside.
Place the zucchini halves in a 13×9-inch baking dish, add about 1 inch of water, and cover with foil.
Bake for 20 minutes until just slightly fork-tender. Remove and set aside to cool slightly.

Cook the Filling

Heat olive oil in a 12-inch skillet over medium heat. Add ground turkey (or beef), onion, bell pepper, and garlic. Cook, breaking up the meat, until meat is fully cooked and vegetables are soft. Drain excess grease.
Stir in chopped zucchini flesh, mushrooms, remaining marinara sauce (reserve 1 cup), parsley, Italian seasoning, salt, black pepper, and crushed red pepper flakes.
Simmer over low heat for 15 minutes, stirring occasionally.

Assemble the Zucchini Boats

Remove water from the partially cooked zucchini in the baking dish. Pour reserved 1 cup marinara sauce into the dish.
Place zucchini halves on top of the sauce and fill each boat with the meat and vegetable mixture. Spoon any extra filling around the boats.
Cover with foil and bake for 20 minutes until zucchini is fork-tender.

Finish with Cheese

Preheat oven to broil. Remove foil and sprinkle zucchini boats with mozzarella, Parmesan, and panko bread crumbs.
Broil for 1–3 minutes, watching carefully, until cheese melts and crumbs turn golden brown.
