Cheesy Zucchini Casserole

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 it 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.

Are zucchini and summer squash the same thing?
Summer squash covers a large variety of squash. Zucchini is actually part of that family, as well as yellow squash. There are a few differences such as a thicker and waxier skin on yellow squash.

Wow— this looks so good. It looks creamy but also crunchy on top. I’m marking it to make later.

That looks so delicious! I love just about anything made with zucchini. Pinned.
Thank you!
Great recipe, great combo of flavors. If you want to use up leftover ham, add the same amount of chopped ham as zucchini, double the sauce & use a larger casserole dish. You probably will have to bake a bit longer (10-15 mins more) due to more volume.
Thanks so much for the info! That will be helpful and sounds delish!
I made this yesterday and it’s SOOOOO good! I did add a few things. I put a thin layer of tomato sauce on the bottom and then a layer of mushrooms. I didn’t have cream so I mixed whole milk with butter as a replacement. Everything else was the same. My husband LOVED it and said he will request it often.
I love to hear that! Did you just use plain tomato sauce from a can? We will have to try that. Thanks!
Made this filling the recipe exactly. Zucchini is raw. Not even a hint of being soft.
