This is the Best Cheesy Zucchini Casserole
I make this all the time for a weeknight side dish, as well as for the holidays! You can easily double or triple this dish and make it for a holiday crowd or dinner party.
This is one of my favorite zucchini casserole recipes! Why? I love that it has sour cream and cheese, is super easy to make, and is keto and low carb friendly.
Who doesn't love the addition of cheese in this casserole? Any casserole with cheese is a favorite in my book - and my family's. Maybe this is because my husband is from Wisconsin? 🙂
Why You will Love This Cheesy Zucchini Squash Casserole
This is a quick and easy zucchini casserole to make. Simply saute the veggies until soft, mix in the remaining ingredients (sour cream, cheese, salt, pepper, and seasoning), then bake!
One Dish Casserole
You don't have to use a 1.5-quart casserole dish if you use an ovenproof skillet! Just saute your veggies until tender then mix in remaining ingredients, top with pork panko and send it straight to the oven!
I love to do this when I'm cooking for my family. If we have company over or, are serving for a holiday meal, I make in a casserole dish
Keto and Low Carb
I love that this zucchini casserole is keto and low carb friendly. Some people may be concerned about carrots. Even with carrots and onion this dish only has 7.4 g net carbs.
If you are concerned about eating carrots you can substitute zucchini in place of the carrots. I don't recommend replacing the onion as it will remove a lot of flavor from the zucchini casserole.
For anyone not following a keto or low carb diet, you can substitute seasoned breadcrumbs for the pork panko. You can also substitute a low-fat sour cream and reduce the butter by 1 tablespoon!

I wish this included an exact measurement for the amount of zucchini to use (i.e. how many cups or ounces?) I have a HUGE zucchini...no idea how to equate it to 4 medium.
Kori says
Hi, the equivalent is about 4 to 5 cups. The recipe is very forgiving. Hope you enjoy!
Ella says
This is 5-Stars the way I made it. Used 5 zucchini, 3 were large other 2 were smaller. Used more sour cream and cheese and used Italian breadcrumbs on top. Also boiled 1/2 the zucchini in pot for 5 minutes (couldn't fit all the zucchini to saute). I'd rather spend a few carbs on few breadcrumbs that carrots in this dish, just never been a fan of pork rinds on casseroles.
