Southwestern Zucchini Casserole is easy, versatile, bombproof and especially nutritious – a family favorite
This Southwestern Zucchini Casserole is a versatile, bombproof recipe that’s also nutritious. You can basically throw it together and it will come out fine. It works fine with zucchini, yellow squash, or a combination. Likewise, proportions do not need to be exact.
I actually experimented with several variations. I also made it without the flour in order to make a keto, gluten-free version. This is also very good, and I’ll likely make it without flour a lot in the future. Without flour, the texture is slightly different – less firm and set; but I thought the taste was just as good. Note that you can also substitute quick oats for a fuller consistency without the gluten. If you like spicy Mexican just increase the green chiles and cumin; I might also add red pepper flakes or smoked paprika. It has plenty of flavor as-is, though.
Also it is good with less cheese or even without cheese; that way it’s a much lighter, lower calorie meal. It’s also good with or without the tomatoes on top. Feel free to vary this one – it’s hard to mess up.
You can also add meat (sausage, ground beef, shredded chicken) if you want to make this a complete meal in one dish for your carnivore family. I specifically wanted a vegetarian/egg dish, though, so I’ll most likely stick with vegetarian options. Mushrooms would be very good in this. I just made it, so we’ll be having it again over the next few days. I already know the leftovers will make a very satisfying meal. Hope you like this one!
