My fellow gardeners, does this happen to you too? Right around this time every year, I start drowning in the long green summer squash. Every year, I have one monster plant that produces and produces and produces. And beside it is a smaller plant that produces and produces and produces. Within the past 2 days, I have harvest 7 large zucchini and I am passing them out to strangers on the street. I am not kidding. Sometimes I leave a box of them on the street corner and by late afternoon, they are all gone.
Things grow big here in Oregon. It’s quite remarkable, really – coming from the east, where things grow rather grudgingly, it blows my mind to watch my garden explode here every year. And we have these gorgeous raised beds in a prime full sun position. The zucchini plants love it and they get so large, I get a little worried they are going to devour my house. I always tell my husband we should plant only one but we end up planting a few zucchini starts in the spring, just in case. And then my sweet, soft-hearted husband can’t bear to pull up a plant that’s doing well. So every year, like clockwork, we drown in zucchini.
Which means I need to up my low carb zucchini recipes game, friends. I have so much to use and not enough ideas to use it all.

How To Make Zucchini Casserole
- Cut the zucchini in half lengthwise, then each half again lengthwise. Chop the quartered zucchini into 1/2 inch slices.
- Lightly boil the zucchini before draining. This helps it release excess moisture so your casserole isn’t soupy. It also helps pre-cook it a bit so the casserole is tender.
- Drain the zucchini well. It still requires this step and I let mine drain in a colander in the sink for about 15 minutes.
- Don’t squeeze the zucchini out. It won’t need it after boiling and draining. You want the pieces of zucchini to hold their shape.
- Layer the zucchini in a greased baking pan and pour the eggs, cream, and cheese mixture over top. It will work its way down into the bottom of the pan and bind the casserole together.
- Sprinkle the top with more cheese and crushed pork rinds for a delicious cheesy crust. Bake at 350F until bubbly and browned.
I honestly can’t believe how good this is. When this zucchini casserole was baking, my mouth was watering from the delicious smells emanating from my kitchen. It was hard to wait until the rest of the family was home to dig in. To be honest, I didn’t. I snuck a few bites as I was getting photos. It was melt in your mouth delicious!
This recipe can easily be doubled for a crowd. Just use a 9×13 pan and enjoy!
