Ingredients Notes

The beauty of this Cheesy Zucchini Casserole lies in its uncomplicated ingredients. Each one plays a vital role in creating a delicious dish, so let’s walk through the key components.

First up, the star of the show: zucchini. You’ll want to use fresh, firm zucchini for the best flavor and texture. Slice it into even rounds or half-moons to ensure uniform cooking. If your zucchini is on the larger side, feel free to remove the seeds for a more balanced dish.

The cheese is where all the magic happens. A blend of shredded mozzarella and sharp cheddar creates the perfect combination of melty and tangy. You can experiment with your favorite cheese varieties, but this pairing gives the ideal melt and flavor.

To add creaminess, we’re using a base of sour cream mixed with a hint of mayonnaise. This duo keeps the casserole rich without being overly heavy. Greek yogurt can be used as a substitute for a lighter version, but the original blend gives the best result.

A sprinkle of breadcrumbs on top adds a delightful crunch. I prefer using panko for maximum crispiness, but any breadcrumbs you have on hand will work. Mix them with a touch of melted butter for a golden, toasty finish.

Lastly, don’t forget the seasonings! Garlic powder, onion powder, and a bit of dried Italian herbs elevate the flavors and complement the zucchini beautifully. These simple additions make all the difference.

How To Make This Cheesy Zucchini Casserole

Making this Cheesy Zucchini Casserole couldn’t be easier. Follow these simple steps for a side dish that’s sure to impress.

Start by preheating your oven to 375°F (190°C) and greasing a 9x13-inch baking dish. A light coating of olive oil or cooking spray will prevent sticking and make for easy cleanup later.

Next, prepare the zucchini. Wash and slice it into ¼-inch rounds or half-moons, depending on your preference. Lay the slices out on a clean kitchen towel or paper towels, and sprinkle with a bit of salt to draw out excess moisture. Let them sit for 10-15 minutes, then pat dry to keep the casserole from becoming too watery.

In a large mixing bowl, combine 2 cups of shredded mozzarella, 1 cup of shredded sharp cheddar, ¾ cup of sour cream, and ¼ cup of mayonnaise. Stir in 1 teaspoon of garlic powder, ½ teaspoon of onion powder, and 1 teaspoon of dried Italian herbs. Fold in the zucchini slices, making sure each one is well-coated in the creamy, cheesy mixture.

Transfer the zucchini mixture to your prepared baking dish, spreading it out in an even layer. For the topping, mix 1 cup of panko breadcrumbs with 2 tablespoons of melted butter. Sprinkle the breadcrumb mixture evenly over the top of the casserole.

Bake in the preheated oven for 25-30 minutes, or until the zucchini is tender and the top is golden brown. You’ll know it’s ready when the cheese is bubbly and the breadcrumbs are perfectly crisp. Let the casserole rest for a few minutes before serving to allow the flavors to meld.

Storage Options

Leftovers are rarely an issue with this Cheesy Zucchini Casserole, but if you find yourself with extra, don’t worry – it stores beautifully. Transfer any leftovers to an airtight container and refrigerate for up to 3-4 days. The flavors will only deepen as it sits.

To reheat, pop a portion into the oven at 350°F (175°C) for about 10-15 minutes, or until warmed through. If you’re in a hurry, the microwave works too, though the breadcrumbs may lose some of their crunch.

If you’d like to freeze this casserole, assemble it up to the point of baking, then cover tightly and freeze for up to 2 months. When ready to bake, thaw overnight in the fridge and bake as directed, adding a few extra minutes if needed.

Variations and Substitutions

This casserole is wonderfully versatile, and there are plenty of ways to make it your own. Here are some ideas to get you started.

For a more robust flavor, consider adding diced bell peppers or sliced mushrooms. They’ll add extra depth and pair beautifully with the creamy cheese sauce.

Want to add some protein? Cooked shredded chicken or ground turkey make excellent additions. Simply fold in the cooked protein before baking for a heartier meal.

If you’re looking to cut down on calories, swap out the sour cream for Greek yogurt. It will still be creamy and tangy, but with a healthier twist.

Craving extra heat? Sprinkle in some crushed red pepper flakes or use a spicy cheese like pepper jack for a little kick. It’s an easy way to add more excitement to the dish.

Feel free to get creative with the cheese blend, too. Gruyère or Parmesan would be lovely additions, lending a richer, more complex flavor. Mix and match to suit your taste buds!

Remember, this recipe is your canvas – don’t be afraid to experiment and make it your own. Happy cooking!
