Easy Zucchini Lasagna Recipe (Not Soggy)

This vegan and gluten-free zucchini lasagna recipe is so delicious! With a vegan cheese sauce and zucchini noodles, this is a nourishing and impressive alternative to classic lasagna. It’s the perfect vegan lasagna recipe.

This Zucchini Lasagna is gluten-free, vegan and a much healthier version to the traditional, using thinly sliced zucchini for lasagna noodles.

I love this vegan zucchini lasagna because of its comforting warm flavours. But most of all, I come back to this recipe because it’s a much healthier version to traditional lasagna – swapping traditional noodles for zucchini – for a gluten-free zucchini lasagna! So I don’t have to feel guilty about indulging in this comforting dish over and over.

So, cozy up to a big dish of this healthy vegan zucchini lasagna. You’re going to love it!

Vegan Zucchini Lasagna Recipe:

I was planning to include this recipe in The Two Spoons Cookbook, but alas – it was a little more Italian than French and so here it is on the blog for you!

This zucchini lasagna follows pretty much the same preparation method as a traditional lasagna. By layering a casserole dish with vegan bolognese sauce, lasagna noodles (in this case zucchini), and homemade cheese sauce (in this case vegan). The only real noticeable difference is in preparing the zucchini noodles.

I will say, that a lasagna recipe requires time – it’s not one of those “recipe-in-20-minutes”, but unless you’re buying a ready-made lasagna, it’s pretty much the same time-requirement as traditional homemade lasagna.

Another easy vegan dinner recipe that’s similar to this is my Stuffed Zucchini Pizza Boats – so definitely give it a try if you’re looking for something fast! I also love my Vegan Baked Ziti which can easily be made gluten-free too.

All-in-all this is one of my favourite gluten-free recipes to make for date-night or a weekend of entertaining. It’s certainly a recipe worth sharing! Whether you’re vegan or not.

How to make zucchini noodles:

So, let’s get into how to make the zucchini noodles for this dish. Zucchinis in general have a high water content, and so the goal is to remove some of the excess water before baking your lasagna. Otherwise it will be too watery.

To do this you’ll want to thinly slice the zucchini using a mandoline, and layer between kitchen towels. Gently press the water out.

Now, we’re not quite done. The next step is to lay your zucchini noodles onto a baking tray and place in the oven on broil for 5 minutes. This will help to bring out more water from the zucchini. Let zucchini cool slightly, then gently pat out any excess moisture with the kitchen towel.

I promise this is the most cumbersome part of the recipe! And tbh – it’s really not too tricky.

How to make vegan bolognese:

Now this part is simple: the vegan bolognese. Made by combining garlic, tomato puree and green lentils. And simmering until thickened.

This simple vegan bolognese can also be used as an easy mid-week tomato sauce for quick pasta dishes.

How to make vegan cheese sauce:

Lucky for you, making this homemade vegan cheese sauce is also simple. The ingredients are:

• cashews (soaked)
• nutritional yeast
• garlic
• lemon juice
• water
• onion powder
• sea salt

Just add the ingredients to a blender until smooth and creamy. You won’t believe just how cheesy this vegan sauce is!

Vegan mozzarella to sprinkle:

To make this recipe less complex I’ve used a store-bought vegan mozzarella cheese in this recipe. However, it’s optional to use.

It’s not always easy to find vegan cheese, but your best bet is at an organic grocers. The brand I used for this recipe is Daiya Mozzarella Shredded Cheese, and I bought it at Wholefoods. I like this brand because it melts well for a stringy style cheese. And it’s similar in texture and taste to real mozzarella. I also like the ingredient list. As it’s minimal and easy to understand.

However, if you can’t find vegan mozzarella cheese at your grocers (or you don’t like the ingredients make-up) than you can can omit the mozzarella altogether and just use my homemade vegan cheese sauce.

Or, if you have a little extra time than I highly recommend layering it with my melty and stretchy vegan mozzarella cheese.

Assembling zucchini lasagna:

Now for the fun part! Assembling your zucchini lasagna.

It begins by lathering a layer of your vegan bolognese into a casserole dish. Next, layer the zucchini noodles on top, side-by-side to cover.

Then, pour a thin layer of homemade vegan cheese sauce, and sprinkle with a thin layer of vegan mozzarella cheese (optional).

Repeat the process until all your ingredients are used up (ending with the vegan mozzarella cheese or homemade vegan cheese sauce).

Now it’s time to bake!

Tips for zucchini lasagna:

How do you keep zucchini lasagna from being watery?

It’s important to follow the instructions below for removing excess water from your zucchini before baking this vegan zucchini lasagna. Otherwise, the outcome will be too wet.

My method for removing the water from zucchini is flawless, and requires no additional salt.

To do this you’ll want to thinly slice the zucchini using a mandoline, and layer between kitchen towels.Gently press the water out.

The next step is crucial: lay your zucchini strips onto a baking tray and place in the oven on broil for 3 minutes each side to steam. You won’t believe how much water steams out!! Let the zucchini cool slightly, then gently pat out any excess moisture with a kitchen towel.

Be sure to follow the detailed instructions in the recipe below, or see how to make zucchini noodles above for more details.

Is zucchini a 1-1 substitute for lasagna noodles?

Not quite… it depends on the size and thickness of your zucchinis. For this recipe I’ve used 3 zucchinis – enough to layer them like noodles.

I’ve sliced my zucchini into noodles using a mandoline. You can also do this by hand, but I find the mandoline is easiest. You can buy mandolines on Amazon. See Shop my Kitchen below for the one I use.

Should you salt zucchini after slicing?

I do not salt the zucchini after slicing, but instead use a different method to remove water content.

After thinly slicing the zucchini using a mandoline, layer them between kitchen towels. Then, gently press the water out. After that, I pop them in the oven on broil for 3 minutes to steam them out. You won’t believe how much steam releases in just a few minutes!

This is a great approach and requires no additional salt. See above on How do you keep zucchini lasagna from being watery above for more details.

Can you freeze zucchini lasagna?

Yes! You can freeze zucchini lasagna! Either slice the lasagna and store in individual peices in air-tight containers, or freeze the whole bake after it’s cooled.

This zucchini lasagna can be frozen for up to 6 months. Reheat in the microwave or in the oven, covered at 350F/180C until bubbling (30 minutes).

My recommendation is to freeze this lasagna after baking. But you could freeze before baking, thaw slightly, then bake fully when ready. 

Where do you buy vegan cheese?

To make this recipe less complex, I’ve used a store-bought vegan mozzarella cheese in this dish, but it’s optional.

Fortunately it’s getting easier to find vegan cheeses at generic grocery stores. The brand I used for this recipe is Daiya Mozzarella Shredded Cheese.

If you can’t find vegan mozzarella at your grocers, you can omit this step and just use the homemade vegan cheese sauce.
