- ½ cup shredded mozzarella cheese: Melts to gooey perfection, creating that irresistible cheesy crust.
- ¼ tsp dried oregano: Infuses the top layer with a gentle aromatic earthiness.
- Fresh basil for garnish: Lends a pop of color and a burst of fresh, herbaceous flavor.

How to Make Lightly grease an 8×8 inch baking dish
Step 1: Preheat and Prepare
Start by preheating your oven to 375°F (190°C). This ensures it’s ready to create that perfect golden bake. Now, remember the all-important step to lightly grease an 8×8 inch baking dish. This simple action prevents your layers from sticking, making serving a breeze and preserving those crisp edges that everyone loves.
Step 2: Prepare the Zucchini
Slice your zucchinis lengthwise into thin, 1/4-inch slices. Brush each side with olive oil and season generously with salt and pepper. The oil helps them brown slightly and keeps the slices tender rather than drying out in the oven.
Step 3: Assemble the Layers
Now comes the fun part! Begin by placing half of your zucchini slices in the baking dish you’ve taken care to lightly grease an 8×8 inch baking dish. Spread half of the ricotta cheese evenly over the zucchini. Next, spoon half of the marinara sauce on top, followed by a generous sprinkle of half the shredded mozzarella. Repeat these layers with the remaining zucchini, ricotta, marinara, and mozzarella. This layering technique ensures every bite is bursting with balanced flavors.
Step 4: Final Touches and Baking
Sprinkle the dried oregano evenly over the top layer of cheese. Place the baking dish in your preheated oven and bake for 20 to 25 minutes, or until the zucchini is tender and the cheese is melted, bubbling, and beautifully golden.
How to Serve Lightly grease an 8×8 inch baking dish

Garnishes
Right after pulling this cheesy, savory masterpiece from the oven, garnish liberally with fresh basil leaves. This not only adds a gorgeous green pop of color but also offers a fresh, fragrant herbiness that brightens the rich layers. For a bit of heat, sprinkle a pinch of red pepper flakes on top — it’s a wonderful way to add an exciting contrast.
Side Dishes
This dish shines as a hearty main course but pairs beautifully with a crisp green salad dressed in a zesty vinaigrette to cut through the richness. Alternatively, roasted vegetables like asparagus or bell peppers complement the cheesy zucchini layers perfectly. Low-carb eaters might enjoy it alongside cauliflower rice or zucchini noodles, keeping the meal light yet satisfying.
Creative Ways to Present
Serving this dish straight from your lightly greased 8×8 inch baking dish gives it that homey, rustic charm. For a more elegant touch, try layering individual portions in small ramekins, garnished with a fresh basil leaf or a small sprig of thyme. You can even turn leftovers into zucchini ricotta melt sandwiches by adding the filling between toasted slices of crusty bread for a fun twist.
Make Ahead and Storage
Storing Leftovers
If you’re lucky enough to have leftovers, store them in an airtight container in the refrigerator for up to 3 days. The flavors actually meld even more overnight, making it an excellent next-day meal.
Freezing
This dish freezes well! After baking and cooling completely, cover your lightly greased 8×8 inch baking dish tightly with plastic wrap and foil, or transfer portions to freezer-safe containers and freeze for up to 2 months. Just thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers in the oven at 350°F (175°C) for about 15-20 minutes until warmed through and the cheese is once again bubbly. You can also microwave single servings, but the oven method helps maintain that signature melted cheese and tender zucchini texture.
FAQs
Can I use a different baking dish size?
While an 8×8 inch baking dish is perfect for this recipe’s proportions, you can use a slightly larger or smaller dish. Just remember to adjust layering thickness and baking time accordingly. The key is to always lightly grease an 8×8 inch baking dish or your chosen dish to prevent sticking.
Can I substitute ricotta cheese?
Ricotta is ideal here for its creamy yet light texture, but you could try cottage cheese blended until smooth or even mascarpone for a richer result. Each swap will change the flavor profile slightly, but it’s fun to experiment!
Is this dish suitable for low-carb diets?
Absolutely! Zucchini is a low-carb vegetable, and combined with ricotta and mozzarella, this dish is relatively low in carbohydrates, making it a great option for keto or low-carb eating plans.
Can I make this recipe vegan?
To make a vegan version, swap the cheeses for plant-based ricotta and mozzarella alternatives, and choose a marinara sauce free of animal products. The layering and baking process remains the same, including the step to lightly grease an 8×8 inch baking dish for perfect results.
Why is it important to lightly grease the baking dish?
Greasing your baking dish might seem like a small step, but it’s essential to prevent sticking and to keep the zucchini melts intact when serving. It also helps achieve nice browning on the edges, elevating the dish’s texture and appearance.
