Ingredients Notes

The magic of this Cheesy Zucchini Casserole comes from simple yet thoughtfully selected ingredients. Each one contributes to the creamy, flavorful, and slightly crunchy experience.

Zucchini forms the heart of this dish. You’ll want to select fresh, firm zucchinis for the best flavor and texture. Make sure to slice them evenly so they cook uniformly. If your zucchinis are particularly large, consider scooping out the seeds, as they can be a bit watery.

Cheese is what makes this casserole shine. A blend of shredded mozzarella and sharp cheddar provides the perfect balance of creaminess and a tangy bite. For a fancier version, feel free to add a bit of grated Parmesan to the mix.

Breadcrumbs create that irresistible golden-brown crust on top. I love using panko for a crunchier texture, but regular breadcrumbs work well too. For a gluten-free option, you can use crushed cornflakes or gluten-free breadcrumbs.

Garlic and onions add depth of flavor. Mince a few garlic cloves and finely chop an onion to sauté until fragrant. This simple step ensures your casserole is far from bland, infusing each bite with savory goodness.

You’ll need a few pantry staples, like olive oil, salt, and black pepper, to bring everything together. For extra zest, a sprinkle of Italian seasoning can work wonders. No special equipment is needed, just a trusty baking dish and a skillet!

How To Make This Cheesy Zucchini Casserole

Creating this cheesy, comforting casserole is easier than you might think. Let me walk you through the steps.

Start by preheating your oven to 375°F (190°C) and greasing a baking dish with olive oil or cooking spray. This helps ensure that the casserole won’t stick, making cleanup a breeze.

Next, prepare your zucchini by slicing it into even rounds, about ¼ inch thick. Place the slices on a kitchen towel and sprinkle them lightly with salt. Let them sit for 10-15 minutes to draw out excess moisture. Afterward, pat them dry to prevent a soggy casserole.

In a large skillet, heat a bit of olive oil over medium heat. Add the chopped onion and minced garlic, sautéing until they’re soft and fragrant. This step infuses the dish with amazing flavor and aroma, setting the foundation for your casserole.

In a mixing bowl, combine the sautéed onions and garlic with your shredded cheese, saving a bit for the top layer. Add the sliced zucchini and toss everything together. Season with black pepper and Italian seasoning if you’d like, mixing well to coat.

Layer the zucchini and cheese mixture into your greased baking dish, spreading it out evenly. Top with the reserved cheese and a generous handful of breadcrumbs. Drizzle a bit of olive oil over the top to help the crust crisp up beautifully.

Bake for 25-30 minutes or until the top is golden brown and bubbly. Let the casserole rest for 5 minutes before serving to allow the flavors to meld. It should be slightly firm yet tender, with cheese oozing over each layer. The total time is about 45 minutes from start to finish, and trust me, it's worth every second.

Storage Options

This Cheesy Zucchini Casserole stores beautifully, making it a great make-ahead option. If you have leftovers, let the casserole cool completely before transferring it to an airtight container. You can store it in the refrigerator for up to 3 days.

For longer storage, you can freeze individual portions. Wrap each portion tightly in plastic wrap and then place them in a freezer-safe container or zip-top bag. The casserole can be frozen for up to 2 months. When you’re ready to enjoy it, thaw overnight in the fridge before reheating.

To reheat, preheat your oven to 350°F (175°C) and bake until heated through. You can also use the microwave for quicker reheating, but the oven method will keep the topping nice and crispy.

Variations and Substitutions

The beauty of this recipe lies in its adaptability. Here are a few ways you can make it your own:

If you’d like to add more veggies, consider tossing in sliced mushrooms, diced bell peppers, or even thinly sliced potatoes. Just be mindful of the cooking time, as some vegetables may take longer to soften.

For an extra protein boost, you can mix in cooked chicken, ground beef, or turkey. This turns the casserole into a hearty main dish, perfect for feeding a hungry family.

Looking to experiment with different cheese varieties? Try a blend of Gruyère, Fontina, or even feta for a more pronounced flavor. A bit of blue cheese can also add a gourmet touch if you’re feeling adventurous.

To make a low-carb version, skip the breadcrumbs and sprinkle crushed pork rinds or finely chopped nuts on top. You’ll still get that satisfying crunch without adding extra carbs.

No matter how you customize it, this Cheesy Zucchini Casserole is a crowd-pleaser. Feel free to experiment and make it your own – cooking should always be a fun and delicious adventure!
