12 Must Try Recipes Made With Zoodles

Substituting veggies for white carbs in traditional dishes is becoming all the rage, and with good reason. Picture this. You could put together a lasagna the traditional way, with white pasta and its simple carbs that offer limited nutrition. Or you could substitute those noodles for one of your favorite veggies. Chances are, this veggie will add flavor, texture, and nutrients no processed carb can! Our Zucchini Lasagna is a perfect veggie lasagna that demonstrates just how healthy you can make dinner when you get creative with veggie substitutions.

Take your zucchini and slice it into long, thin slices. We like to use a mandoline for perfectly thin strips of veggies, but if you don’t have a mandoline in your kitchen, make sure to choose your sharpest knife, and slice away, with your fingers out of the way! Then, begin to layer your lasagna, just as you would with a traditional lasagna. Spread a layer of marinara sauce to the bottom of your pan, and layer the zucchini “noodles” on top. Then, spread another layer of sauce, and add your mixture of cottage cheese, egg, parmesan, mozzarella, and herbs. Keep layering until you have what looks like a classic lasagna, and then bake.

Serve this to family on a weeknight, or to guests at dinner on the weekends. Sure, some of your diners might object to the idea of zucchini used as noodles, but when they bite into this lasagna, the texture of zucchini paired with ooey gooey cheese with have them singing a different tune.

  • Combine in a mixing bowl the cottage cheese, parmesan, egg, and mozzarella.

  1. I made this last night, and it was incredibly watery. I baked this on the middle rack, but cooked it for another 20 or so minutes uncovered on the top rack. I wonder if I should have used the bottom rack for the main baking. I also only used 2 zucchini, sliced thin on my mandoline – I can't imagine how much more watery it would have been had I used thicker slices or 3 full zucchini. The flavor was great , but it was just mush. I'm going to heat some up tonight – maybe sitting in the fridge overnight will help it to thicken up.

    1. Beth, I've got the perfect solution. Salt your zucchini on both sides before adding to the casserole. This should prevent it from making the lasagna watery. No need to bake on the bottom rack, in fact, it
      might burn or overcook. Let us know if this helps. I'll also make a note in the recipe. Thanks! 🙂

  2. I just made this and it was yummy even though there was a little soupy water at the bottom. I added a layer of ground elk in the middle. I also accidentally skipped the roasting of the zucs before layering but it didn’t seem to affect the end result. Will definelty make again. Good recipe! My fave part was the cheese mixture.

  3. This was a delicious zucchini lasagna soup! It was super wet but we put ours in bowls and ate with a spoon 🙂

  4. If you don’t want to use meat you can also try the Tofu crumbles that looks like meat, I buy it at the Publix Supermarket it comes in original or hot. When I make my spaghetti or lasagna sause instead of meat I use the tofu.
    I’m hispanic so I make it flavorful, (I use garlic, cilantro, onions, oregano, peppers then you sauté everything and the sause and wala magnific!

  5. I made this for a party last night as the hosts are eating a keto diet. It was a hit with everyone! I loved it. I made some slight mods in that I did not slice the zucchini, I used my pampered chef simple slicer and made circles, and no cottage cheese as I can’t get it where I live so I just used more of the other cheeses. Super good though. Will make again for sure. Next time, I’m adding some red pepper flakes to give it a little more kick!

  6. I made this last night and loved it! I followed the recipe, used a 9×13 dish, and didn’t cover it because I was out of foil! I let it sit about 1/2 hr before eating and it was not watery at all! Thank you!

  7. Just made this. I didn’t see the size of baking dish listed. I read that someone used a 9×13, and the photo shows an 8×8. I compromised with a 9×9. This recipe barely made the two layers. In fact, I had to make another recipe of the cheese mix and that barely covered. Next time I will double recipe and use an 8×8 pan. It’s in the oven baking now – can’t wait to try it.
