Equipment Needed
You don’t need fancy kitchen gadgets for this recipe. Here’s what you’ll need:
- Baking Dish: A 9×13-inch dish works best for this casserole.
- Knife: For slicing the zucchini evenly.
- Mixing Bowls: To toss the zucchini and prepare the breadcrumb mixture.
- Cheese Grater: If you’re grating fresh Parmesan or mozzarella.
- Oven Mitts: Safety first when handling that hot dish!
If you don’t have a baking dish, you can use a cast-iron skillet or any oven-safe pan as an alternative. Just make sure it’s large enough to hold everything.
Preparation Method
- Preheat the oven: Set your oven to 400°F (200°C). Lightly grease your baking dish with olive oil or nonstick spray.
- Prepare the zucchini: Slice the zucchini into 1/4-inch rounds. Toss them in a large bowl with olive oil, garlic powder, salt, and black pepper.
- Layer the zucchini: Arrange the zucchini slices in a single layer in the baking dish, slightly overlapping them.
- Add the cheese: Sprinkle half of the mozzarella and Parmesan evenly over the zucchini layer.
- Prepare the breadcrumb topping: In a small bowl, mix the breadcrumbs, Italian seasoning, and melted butter until combined.
- Add the topping: Sprinkle the breadcrumb mixture evenly over the cheese layer. Follow with the remaining mozzarella and Parmesan.
- Bake: Place the casserole in the oven and bake for 25-30 minutes, or until the cheese is bubbly and the breadcrumbs are golden brown.
- Cool slightly: Let the casserole rest for 5 minutes before serving to allow the layers to settle.
Your kitchen will smell absolutely amazing while this bakes—it’s the kind of dish that makes everyone linger near the oven!
Cooking Tips & Techniques
- Don’t skip salting the zucchini: This helps draw out excess moisture to prevent a watery casserole.
- Use fresh cheese: Pre-shredded cheese is convenient but often contains anti-caking agents that affect melting. Grating your own mozzarella and Parmesan makes a huge difference.
- Watch the breadcrumbs: If they’re browning too quickly, cover the casserole loosely with aluminum foil for the last 10 minutes.
- Test the zucchini: The zucchini should be tender but not mushy. Overbaking can make it lose its texture.
- Multitask: While the casserole bakes, prep a quick side salad or garlic bread to round out the meal.
Variations & Adaptations
- Low-Carb Option: Skip the breadcrumbs and top with crushed pork rinds or almond flour for a keto-friendly version.
- Add Protein: Layer cooked chicken breast or crumbled Italian sausage between the zucchini and cheese layers for a heartier dish.
- Seasonal Swap: Replace zucchini with yellow squash or eggplant, depending on what’s in season.
- Dairy-Free: Use vegan mozzarella and Parmesan alternatives to make the dish dairy-free.
- Spicy Twist: Add a pinch of red pepper flakes to the breadcrumb mixture for a bit of heat.
One variation I tried recently was adding a layer of marinara sauce under the zucchini for a lasagna-like vibe. It was an instant hit!
Serving & Storage Suggestions
This casserole is best served warm from the oven. Pair it with a crisp green salad, garlic bread, or steamed veggies for a complete meal. For beverages, a light white wine or sparkling water with lemon complements the flavors beautifully.
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply pop individual portions in the microwave for 1-2 minutes or warm the entire dish in the oven at 350°F (175°C) until heated through. You can also freeze it for up to a month—just wrap tightly with plastic wrap and foil before freezing.
