It took me years (and I really do mean years) to find a vegetable that my daughter loved.
I mean, she ate vegetables because I forced her to have a few bites at every meal, and there were certainly a few that she’d eat without complaining about, but there were none that she’d request.
She got the grilled chicken that came with rice and grilled vegetables and the kid devoured her veggies and started stealing them from her daddy, who really is not a veggie fan. He was happy to get them off his plate. 😉
The zucchini was her favorite and she regularly asks for zucchini at home which is how this cheesy zucchini casserole came to be.
How to make zucchini casserole:
I wanted to keep this zucchini casserole simple and kid-friendly, so I obviously went the cheese route. Who doesn’t love cheese?!
You’ll want to slice up some zucchini and toss that into a hot skillet with some onion and cook for a few minutes until the veggies are tender crisp. Stir in some garlic and let cook until it smells divine in your kitchen.
Add that mixture to a colander to drain for about 10 minutes. The cooking will help the zucchini release some of it’s water and you can drain it away rather than have a soggy casserole.
Toss all that in a mixing bowl with some cheese, eggs, salt, and pepper. Stir well and then transfer the mixture to an 8×8 baking dish.
I like to sprinkle just a bit of extra cheese on top. Who doesn’t love cheese after all?
Pop it in a hot oven and bake for about 30 minutes.
Sprinkle with some fresh herbs and serve! I used parsley, but whatever you have on hand would probably work well . Chives, a little dill, some basil – it’s all good.
How many carbs are in zucchini:
Zucchini is a great option for a low carb diet!
One medium zucchini contains 6 grams of carbs and 2 grams of fiber, making for just 4 net carbs per zucchini.
Zucchini also packs in over 500mg of potassium and over half your daily vitamin C!
