How to Make Zucchini Casserole

Step 1: Prep Your Zucchini

Start by washing and slicing your zucchini into thin, even rounds or half-moons. To avoid excess moisture making the casserole watery, sprinkle the slices lightly with salt and place them in a colander for about 15 minutes, then pat dry with paper towels.

Step 2: Sauté Aromatics

In a skillet, warm some olive oil and sauté finely chopped onions and minced garlic until softened and fragrant. This base layer infuses the entire casserole with rich flavor.

Step 3: Mix the Ingredients

In a large bowl, combine the sautéed garlic and onion, zucchini slices, beaten eggs, shredded cheese, fresh herbs, salt, and pepper. Toss gently to mix everything evenly, ensuring each bite delivers perfect balance.

Step 4: Assemble the Casserole

Transfer the zucchini mixture into a greased baking dish and smooth the top. Sprinkle breadcrumbs evenly over the surface to add a satisfying crunch after baking.

Step 5: Bake to Perfection

Place the dish in a preheated oven at 350°F (175°C) and bake for around 30-40 minutes, or until the top is golden brown and bubbly. Let it cool slightly before serving to let the flavors settle.

Pro Tips for Making Zucchini Casserole

Drain Excess Moisture: Salting and draining your zucchini slices prevents a soggy casserole.
Layer Flavors: Don’t skip sautéing the aromatics—they add depth to the final taste.
Use Fresh Herbs: Fresh herbs brighten the dish and enhance overall flavor more than dried versions.
Don’t Overbake: Bake just until the top is golden and bubbling to keep the veggies tender but not mushy.
Quality Cheese Matters: Choose good melting cheeses for that creamy texture everyone loves.

Creative Ways to Present

Make Ahead and Storage

Storing Leftovers

After cooling, cover your zucchini casserole tightly with plastic wrap or transfer to an airtight container and store it in the refrigerator for up to 3-4 days to enjoy later.

Cheddar, mozzarella, Monterey Jack, or a blend of these cheeses melt well and provide rich flavor and creaminess in the casserole.

Instructions

Prep Your Zucchini: Wash and slice the zucchinis into thin, even rounds or half-moons. Sprinkle them lightly with salt and place in a colander for about 15 minutes to draw out excess moisture. Afterward, pat dry with paper towels to prevent a watery casserole.
Sauté Aromatics: Heat olive oil in a skillet over medium heat. Add the finely chopped onion and minced garlic. Cook, stirring occasionally, until they soften and become fragrant, about 3-5 minutes. This step builds a rich flavor base for the casserole.

Assemble the Casserole: Grease a baking dish with a little olive oil or non-stick spray. Transfer the zucchini mixture into the dish and spread it out evenly, smoothing the top. Sprinkle the breadcrumbs evenly over the surface to create a crunchy topping.
Bake to Perfection: Preheat your oven to 350°F (175°C). Place the casserole in the oven and bake for 30-40 minutes, until the top is golden brown and bubbling. Remove from the oven and allow it to cool slightly before serving to let the flavors meld.

Use Fresh Herbs: Fresh parsley, basil, or thyme enhances flavor better than dried herbs.
Don’t Overbake: Remove when the top is golden and bubbling to keep veggies tender.
