Tender zucchini halves filled with a flavorful mixture of tomatoes, green onions, breadcrumbs, and Parmesan cheese, baked to perfection. This fiber-rich, protein-packed dish is quick to prepare, oven-friendly, and perfect for a nutritious weeknight dinner or meal prep.
Preheat the Oven and Prepare Baking Dish: Begin by preheating your oven to 350°F (175°C) so it’s ready when the zucchini are prepared. Lightly grease a medium-sized baking dish (approximately 8×8 inches) with a little butter, olive oil, or cooking spray. This prevents sticking and ensures easy serving later. Set the dish aside while you prepare the zucchini.
Wash and Halve Zucchini: Rinse the zucchini thoroughly under cold running water to remove any dirt or residues. Pat dry with a clean towel. Slice each zucchini in half lengthwise, creating two long, even halves. These will serve as your “boats” for the stuffing.
Soften Zucchini (Microwave Step): To make scooping easier and avoid cracking, place the zucchini halves on a microwave-safe plate and microwave for 2-3 minutes. This gently softens the flesh while keeping the outer shell intact. Allow them to cool slightly before handling.
Scoop Out Zucchini Flesh: Using a sharp knife, carefully score about ¼ inch from the edge of the zucchini flesh to create a boundary for the stuffing. With a spoon, gently scoop out the interior flesh, leaving the outer shell intact. Place the removed zucchini flesh in a bowl for later use in the stuffing mixture.
Prepare Saute Base (Butter and Oil Step): Heat a medium to large skillet over medium-high heat. Add 1 tablespoon of butter and 1 tablespoon of olive oil. Let the butter melt completely and combine with the oil for a rich cooking base.
Saute Green Onions (Aromatic Foundation): Add the chopped green onions to the skillet and cook for 2-3 minutes, stirring occasionally. The onions should soften slightly and release their aromatic flavor, creating a flavorful foundation for the stuffing.
Combine Stuffing Ingredients (Mixing Step): To the skillet, add the reserved zucchini flesh, diced Roma tomatoes, ½ cup breadcrumbs, ½ cup Parmesan cheese, and a pinch of salt and black pepper. Stir gently but thoroughly, ensuring all ingredients are evenly incorporated into a cohesive stuffing mixture. Remove the skillet from heat.
Fill Zucchini Boats (Stuffing Step): Carefully spoon the prepared mixture into each zucchini half, pressing gently to ensure the filling is evenly distributed and slightly mounded. Place the stuffed zucchini into the prepared baking dish.
Add Topping and Drizzle (Finishing Touch): Sprinkle a little extra Parmesan cheese over the top of each stuffed zucchini for a golden, cheesy finish. Drizzle lightly with olive oil to enhance browning and flavor during baking.
Bake the Zucchini (Oven Cooking Step): Place the baking dish in the preheated oven and bake for approximately 20 minutes. The zucchini should be tender when pierced with a knife, and the top should turn lightly golden brown.
Check Doneness (Final Test): Test the zucchini by inserting a sharp knife into the center. If it slides in easily and the stuffing is heated through, your dish is ready. Remove from the oven and let cool for 2-3 minutes.
Serve and Enjoy (Serving Step): Transfer the baked stuffed zucchini to serving plates. Pair with a fresh salad, whole grains, or enjoy as a standalone dish. The cheesy, savory filling combined with tender zucchini makes each bite flavorful and satisfying.
Storage Tip (Optional Step): If you have leftovers, store them in an airtight container in the refrigerator for up to 2 days. Reheat gently in the microwave or oven to preserve the texture and flavor.
Notes
Choose medium-sized zucchini for the best balance between tender flesh and sturdy shells. Overly large zucchini may require longer baking and can become watery.
Microwaving the zucchini before scooping softens it, making it easier to hollow out while preventing the shells from cracking.
The stuffing can be adjusted according to taste: add finely chopped mushrooms, bell peppers, or cooked quinoa for extra flavor and nutrition.
Use freshly grated Parmesan cheese for a richer, nuttier flavor and better browning on top. Pre-grated cheese can work but may not melt as evenly.
Ensure the filling is well combined but not overly wet; excess moisture can make the zucchini soggy.
