1-First Step: Prep and mise en place Preheat the oven to 400 degrees F. Coat a large rectangular baking dish with cooking spray. Trim the stem ends off 4 medium zucchini and cut each zucchini in half lengthwise so you have 8 halves. Use a spoon to scoop out the flesh carefully, leaving about a 1/4-inch wall so the boats hold their shape while baking. Reserve the scooped flesh if you want to stir it into the meat filling later to reduce waste and boost moisture. Place the hollowed zucchini shells cut-side up in the prepared baking dish. Sprinkle 1/2 teaspoon dried Italian seasoning plus salt and pepper to taste over the zucchinis so they start to pick up flavor while the filling is made.

2-Second Step: Make the meat filling Heat 2 teaspoons olive oil in a large pan over medium-high heat. Add 1 pound mild Italian sausage with casings removed and cook for 4 to 5 minutes, breaking it up with a spatula into small pieces. When the meat has lost most of its pink, add 1/2 cup finely diced onion and cook an additional 4 minutes until the onion softens. Stir in 1 teaspoon minced garlic and cook for 30 seconds until fragrant. Season with a pinch of salt and pepper. Pour in 2 cups marinara sauce and bring the mixture to a simmer. Let it cook for about 5 minutes so the flavors marry and the sauce reduces slightly. If you reserved the scooped zucchini flesh, chop it and add it to the pan now, stirring until incorporated.

3-Third Step: Assemble the boats * Spoon the meat and sauce mixture evenly into each zucchini shell so each boat is generously filled but not overflowing. * Top each filled zucchini with a generous sprinkle of 3/4 cup shredded mozzarella cheese, distributing it evenly so each boat gets a nice melt. * If you like a crispier topping, add a light sprinkle of breadcrumbs or grated Parmesan before baking.

4-Fourth Step: Bake and finish Place the baking dish in the preheated 400 degrees F oven and bake for 25 minutes, or until zucchini is tender and cheese is melted and golden brown. Larger zucchini may need a few extra minutes; check at around 20 minutes to avoid overcooking. Remove from the oven and let the boats rest for 3 to 5 minutes. Sprinkle 1 tablespoon chopped parsley over the top for color and a fresh herb note.

5-Final Step: Serve and enjoy Serve warm, straight from the baking dish. These zucchini boats pair beautifully with a simple side salad or a grain like garlic butter rice for a heartier meal. Try pairing with a quick rice side such as garlic butter rice with kale for an easy family dinner.
