If you’re drowning in zucchini, an easy zucchini gratin recipe is the perfect way to use up a good amount. This low carb cheesy zucchini casserole requires three medium zucchini in a 1 1/2 quart casserole dish, but you can easily double (or even triple!) the recipe to make more in a larger pan!
As we head into August, I know I’m not the only one with more zucchini than I know what to do with. Anyone with a garden will say that right now! I keep meaning to start a garden, but never have the time. One of these years I’ll take the plunge.
For now, despite no garden, I still have a zucchini problem. It’s my own fault, too. I just couldn’t resist buying way too much at the farmers’ market. It’s a good thing my family loves zucchini as much as I do. All the more reason to make zucchini au gratin, right?
Fortunately, it’s Zucchini Week here at Wholesome Yum, so I have lots of ways to use up all my zucchini! So far, I’ve made zucchini pizza bites, fried zucchini & squash, and zucchini noodle salad with bacon and tomatoes. I can’t even decide which one I like best.
Low carb zucchini gratin is yet another way I’m using zucchini this week. With a delicious creamy brie sauce, cheesy Swiss Gruyere topping, Italian seasoning, and summer zucchini (of course!), you can’t go wrong. It’s the ultimate comfort food.
Cheesy low carb casseroles like this one are my favorite kind. If you’re a fan of them too, you’ll want to check out my brussels sprouts casserole au gratin, pesto chicken bake and low carb cauliflower casserole. Can’t forget to add this cheesy zucchini casserole to the list!
You’ll love how easy it is to prepare this cheesy zucchini gratin bake. The active prep time is only then minutes!
The “hardest” part is impatiently waiting for the sliced zucchini to drain in the beginning. (Patience is not my strong suit.)
You don’t want to skip the draining step, though. It prevents the zucchini casserole from being too watery. While the zucchini drains over the sink, you can use the passive time to make your main dish. (Or, get out of the kitchen and spend some time outside!)
This low carb zucchini gratin recipe uses common ingredients that I often have around. I recommend using brie in the sauce as written, but feel free to swap any shredded cheese you like for the topping. I used a blend of Swiss and Gruyere for lots of depth and flavor. Cheddar would be delicious, too!
