What you need for No Noodle Vegetarian Zucchini Lasagna
This No Noodle Vegetarian Zucchini Lasagna uses just a few simple ingredients!
- Zucchini: To get the best thin slices, I recommend cutting the zucchini with a mandolin. I love this one. (affiliate link)
- Mushrooms: Hearty portobello mushrooms add a meaty texture and rich flavor that you don't find from other mushrooms.
- Ricotta: Thick and creamy ricotta cheese works perfectly for this lasagna. You can use fat-free or full fat depending on your diet.
- Cheese: You'll need shredded cheese. You can pick either mozzarella or an Italian cheese blend. I also included some parmesan in this recipe. Depending on how much time you have, you can shred your own. It melts better that way but pre-shredded also works!
- Egg: An egg helps keep the ricotta mixture together and makes it fluffy.
- Favorite Pasta Sauce: Use your personal favorite pasta sauce or make your own. Here is my Slow Cooker Marinara recipe.
- Spices: I added basic Italian seasoning to my ricotta mixture. If you don't have that use any combination of basil, oregano, or parsley.
How to make No Noodle Zucchini Lasagna...
Curious how to make vegetable lasagna without noodles? This recipe for Vegetable Lasagna No Noodles is quite a few steps, but it is worth it!
- Cut zucchini "noodles" with a mandolin. Be careful not to cut your hands. I use these gloves when I use my mandolin because I'm kind of clumsy. 🙂
- Get the water out of the zucchini by sprinkling the zucchini slices with salt. Allow the zucchini to sit and then blot it off as much as possible.
- Roast zucchini in the oven at 400 degrees to help get more water out of it and turn it into "noodles." When they are done cooking dry the noodles off again. You can even leave the noodles sitting on paper towels while you prep the rest of the lasagna. This might seem tedious, but it really helps keep the lasagna from turning into just water.
- Cook the mushrooms by sauteing them over medium heat for 5-8 minutes.
- In a bowl, mix ricotta, eggs, and Italian seasoning.
- Layer Lasagna by adding the marinara sauce, then the zucchini noodles, ricotta mixture, mushrooms, and then cheese! Repeat for a second layer and finish with a last zuchini noodle layer and shreded cheese.
- Bake the No Noodle Zucchini Lasagna until bubbly.
Variations & Pro Tips
- To keep this lasagna vegetarian, use your favorite meat crumbles substitute instead of the mushrooms.
- Add some red pepper flakes in your marinara to give the vegetarian zucchini lasagna without noodles a kick.
- Add some spinach or kale to your ricotta mixture for more nutrition.
- Use cottage cheese instead of ricotta for an even creamier no noodle vegetarian lasagna.
How do you get the water out of zucchini lasagna?
Zucchini is naturally VERY watery is it's super important to take a few steps to keep this zucchini lasagna from being too watery. The amount of water in individual zucchini can also vary so sometimes it's hard to get it all out.
- Slice the zucchini into thin slices (I.e. mandolin). Thinner slices mean less zucchini which results in less water content.
- Salt the zucchini slices and allow to sit for 15 minutes before assembling the lasagna. Adding salt helps to draw out the moisture. Blot the slices with a paper towel.
- Roast the zucchini to pull even more moisture out of it. Continue to blot the zucchini noodles and allow it to sit on paper towels to dry out while you get the rest of the lasagna ready.
- Remove the foil during the second half of the baking time to allow the dish to continue to dry out.
- If you STILL end up with some water in the dish just cut the first piece of lasagna out and let the water drain to one side of the pan. Use a paper towel to blot up the extra moisture. Even if you still have some water, it will still taste amazing.
What can I use if I don't have a mandolin?
A mandolin works best by far but if you don't have one you can use a large chef's knife or get smaller zucchini and use a sharp vegetable peeler.
Do you rinse zucchini after salting?
NO! If you try to rinse it you will just add the moisture BACK into the zucchini and our goal is to get all the moisture out. Most of the salt with come off when you blot it however a little salt makes it taste better.
Should you peel zucchini?
You don't need to peel the zucchini, just slice it and you're good to go!
What other veggies can you use?
The options are endless when it comes to this vegetable lasagna! Use your favorite veggies - onions, peppers, spinach, and even eggplant! Just saute the vegetables you want to add with your mushrooms until they are tender.
My No Noodle Vegetarian Zucchini Lasagna is a labor of love… but boy is it worth it! The finished product is filling and delicious AND it is totally enough to handle any carb-y cravings you might have in a low carb, no pasta kind of way.
