Parmesan Zucchini Casserole can be enjoyed as a vegetarian meal or serve it alongside a Baked Chicken Breast as a side dish. You will find either option to be a hit with most everyone.
I usually make Zucchini Bread or Chocolate Chip Zucchini Muffins when I have zucchini on hand. My kiddos will typically eat both of those because of the added sweetness. Lately, they have become more adventures eaters and will eat savory zucchini recipes.
Since this is a cheesy and creamy casserole, it is best to prepare just before serving. I have never encountered leftovers to know if reheating the dish is an option. If you should decide to give reheating a try, you may need to add a splash of milk to help the cheese heat evenly.
I used a combination of green zucchini and yellow squash since I had both on hand. You can make this zucchini casserole with all green or with a combination of zucchini and summer squash.
How to pick good zucchini?
Choosing the best zucchini is always essential for a great casserole. Try to purchase small sized with shiny skins. Also, check for firmness. A more firm zucchini will bake and taste so much better. Stay clear of any blemished skins.

How to Make Baked Parmesan Zucchini Casserole
To make this zucchini casserole, I dice a small onion and slice both yellow and green zucchini. Feel free to use all green or all yellow zucchini if that is what you have on hand. The two colors make the casserole visually appealing. If you have picky eaters that are not fans of onion, you can omit or puree the onion. The onion adds some additional flavor.
Next, we add the onion, garlic, and the salt and pepper to a medium to large-sized skillet. Let this cook until the onions are translucent.
Grab a stick of butter to heavily coat the baking dish before adding the sliced zucchini.
For the next step, the heavy cream is added to the onion and garlic mixture. The cream will need to be heated to just about boiling.
Then, most of the parmesan cheese is mixed in until melted.
The mixture will be quite thick but spreadable at this point.
We add the mostly melted creamy mixture to the top of our zucchini slices. The foil will need to be tented to keep our vegetables from burning.
After the zucchini has baked, the final step is to add the remaining cheese. It’s then baked for a few minutes longer.
Be cautious of over baking this casserole. If zucchini is baked longer, you will have a very liquidy dish and the zucchini will become mushy.
