Vegetable lasagna using zucchini noodles (Nightshade free)

What is a nightshade? Tomatoes, potatoes, peppers, and eggplant are all in the nightshade family. Many people are sensitive to them, including me. So I wanted to develop a few recipes that we know and love that didn’t have them. My extended family is gluten-free, so I used zucchini noodles instead of pasta to make it gluten-free too.

With the allergies in my family, a meal that we can all enjoy that’s mixed in one pan is a rarity. This one might fit the bill!

Lasagna noodles substitute

Zucchini makes a great lasagna noodles substitute. They taste great, cook fast, and take on amazing flavors. Using zucchini noodles instead of pasta saves you a ton of time in this recipe. One of my daughter’s favorite vegetables in zucchini, so that makes it a win as well.

Baked zucchini noodles

Baking the zucchini noodles for a short amount of time like for a lasagna makes them turn out perfectly. If you precook the zucchini, it would be too soggy, but if you put the zucchini noodles in raw, they bake perfectly.

It’s simple to make the noodles. All you need is a zucchini and a potato peeler. You can make paper-thin strips this way. Or you can take the zucchini and cut it thinly with a knife but thicker than the shaved noodles. I like them thicker, about 1/8 inch thick. It gives them a little more sturdiness for cutting the lasagna and serving it.

Garlic parmesan zucchini noodles

If you want to make garlic parmesan zucchini noodles in a bowl instead of lasagna, you can either shave them with a potato peeler or spiralize them if you want a thicker texture. They cook up quickly and take on amazing flavors of garlic and parmesan. I big ole bowl of zucchini noodles is comforting and delicious.

Nomato sauce

If you can’t get past missing the tomato sauce, you can make a homemade nomato sauce or use a store bought one in a jar. This sauce uses a variety of vegetables to make a similar sauce to tomato sauce.

The basic ingredient to make the texture is pumpkin puree, but it combines multiple vegetables to make a well rounded imitation tomato sauce that is pleasing to eat. If you don’t think it sounds yummy, give it a try and you might change your mind.

Spinach parmesan zucchini noodles

I love the flavors of spinach, garlic, and parmesan for this zucchini lasagna. I never miss the pasta at all. I like to make meals without meat, but you could add seasoned ground beef or sauted chicken breast pieces to this lasagna if you need meat in every meal.

Zucchini has a lot of water in it and so does spinach. In order to make a zucchini spinach lasagna that’s not full of water, you need to prep the zucchini by drawing out the water with salt. And wilt the spinach in a skillet and then let it cool and squeeze the rest of the water out of it.
