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.

Cream, brie, Italian seasonings, salt, pepper, and minced garlic in a saucepan.

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.

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

  3. That looks so delicious! I love just about anything made with zucchini. Pinned.

  4. 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.

    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.

    1. 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.
