This casserole recipe came from my friend, Beth, who always has the best recipes.
She is great at cooking for a lot of people, and when I am in need of something good, she is the one I call.
I took a few things about the recipe and changed them. So, it’s a versatile recipe. You can add cheddar instead of mozzarella, or forgo the breadcrumbs.

Step-By-Step Instructions For Zucchini Casserole with Panko
Spray the bottom of a casserole dish with nonstick spray.

Start by slicing the zucchini. Add the sliced zucchini to the baking dish.
For this recipe, I used an 8″ x 8″ casserole baking dish.

Sprinkle half of the mozzarella cheese over the zucchini and set aside.

Add the heavy cream and minced garlic to a medium saucepan on medium heat.

Next, add the brie cheese, Italian seasonings, salt, and pepper. Cook until the ingredients are melted.
I cut the top and side off of the brie and scraped into the saucepan so I didn’t have any rind in there.
Rind won’t hurt you, but I don’t like the flavor as much, so I didn’t add it in.

Pour the heavy cream mixture over the zucchini mixture.

Top with the remainder of the mozzarella cheese, Panko breadcrumbs, and parmesan cheese.

Cover the dish with tin foil and bake for 20 minutes at 400-degrees.
After 20 minutes, remove the tin foil and bake for 10 more minutes or until the top is golden brown.
The zucchini casserole recipe ends up being the perfect addition to your dinner table and features a crunchy topping over a cheesy bed of vegetables.
