Healthy Zucchini Casserole recipe is baked with herbs and spices and the perfect amount of shredded cheese! A low carb and gluten free summertime side dish.
Preheat oven to 375 degrees F and spray large 9 x 13 baking dish with cooking spray. Place chopped zucchini in a colander lined with kitchen towel and sprinkle with salt. Toss with your hands and let sit for 10 minutes.
In the meanwhile, in a large bowl whisk the eggs. Add onion, garlic, olive oil, basil, oregano, pepper, red pepper flakes and 1/2 amount of both cheeses. Whisk.
Squeeze zucchini in a towel over the sink for a few minutes. At first there won't seem much liquid but keep twisting at the top of the towel, turning and squeezing the ball.
Add squeezed zucchini to the bowl with mixture, stir to coat and transfer to previously prepared baking dish. Sprinkle with remaining 1/2 of both cheeses.
Bake uncovered for 25 minutes. Remove from the oven and serve warm or cold.
Notes
Store: Refrigerate covered for up to 3 days.
Make ahead: Refrigerate assembled and covered for up to 1 day, then bake as per recipe.
Do not freeze. Not before, not after baking.
Onion: I used an abundance of young onions this time.
Do not bake covered: Casserole will be extra watery and unappealing.
