Vegetable Lasagna is what you make when you want to load up on veggies with something that’s filling, comforting and so moreish, you don’t even think twice about it being Meat Free!
This incredible Vegetarian Lasagna is made with a creamy ricotta and spinach filling as well as layers of roasted vegetables and a homemade tomato lasagna sauce. It’s one of my favourite fridge clean out recipes because it can be made with just about any roastable veggies!

Why you’ll love this Vegetable Lasagna
It is hard to top an epic, meat lasagna made with layers of slow cooker ragu, béchamel sauce and oodles of cheese. But if there’s anything that can give it a run for its money, it’s this Vegetarian Lasagna. Here’s why you’ll love this so much:
Roasted Vegetables – Roasting trumps stove sautéing when it comes to bringing out flavour in vegetables;
Jar Roasted Red Peppers – with a touch of smokiness and sweetness, this is an optional extra that I love to add because it adds that extra special touch;
Customisable – use whatever roast-able veggies you please;
Spinach and Ricotta layer – It just takes this over the top! But it’s optional – you could easily just double up with another layer of roasted vegetables;
Simple homemade lasagna sauce – skip the jar, this homemade tomato sauce is simple and so good!
Cheese – goes without saying that melty cheese is all part of a great lasagna experience!

How to make Veggie Lasagna
There are a few components to putting together a Veggie Lasagna so we love that it makes a BIG batch and that it reheats 100% perfectly!
Roast vegetables;
Mix up ricotta and spinach;
Make the simple tomato lasagna sauce;
Layer the lasagna as follows:
Smear tomato on base (to stop lasagna sheets from sliding)
Top with lasagna sheets
Roasted vegetables
Some tomato pasta sauce plus cheese
Another layer of lasagna sheets
Spinach and ricotta filling for lasagna
Top with lasagna sheets and pasta sauce
Sprinkle with cheese. Ready to bake!

Vegetarian Lasagna ingredients – vegetables
Roasted Vegetables
I used pumpkin, zucchini and onion as my roasted veggies, but feel free to use whatever you have / want. Anything roastable is fine, just chop it so it cooks in the same time.
I cut mine pretty chunky because otherwise they cook too quickly in the oven – I like to roast veggies for at least 20 minutes minimum to get the maximum benefit of caramelisation.
Roasted Red Peppers
My “special ingredient” – Roasted Red Peppers! Basically, it’s capsicum / bell peppers that have been fire roasted so they have that gorgeous smokey flavour.
It’s sweet, soft and slippery and it adds an awesome extra dimension to this lasagna. Yep, I take the easy route and buy it in a jar but if you’re a keen bean, make your own!

Vegetable lasagna is sensational served fresh out of the oven, but it’s also one of those dishes that are terrific the next day. The flavour of those roasted veggies and that spinach ricotta layer develop overnight, and just a quick reheat in the microwave is all that’s required to bring it back to the original molten state.
So, fellow Carnivores. Have I convinced you to give this a go??? 😜 – Nagi x

- Roast for 25 minutes, turning at 15 minutes, until tender and browned.
- Remove from oven, loosen from tray with spatula while warm (can stick when cools).
Sauce:
- Heat oil in a skillet over medium high heat. Add garlic and onion, cook for 3 minutes until golden.
- Add passata, crushed tomato, water, dried herbs, chilli, salt and pepper. Stir. Simmer on medium low heat for 20 minutes. Adjust salt at the end. *Add a teeny touch of sugar if it’s a bit sour, depends on quality of tomatoes used.*

Made this yesterday and it turned out so good! Thank you for sharing. Definitely will become a regular in our house
Woot! I’m so happy it was a hit Jemma ❤️
I made this months ago and absolutely loved it! We are having meat loving guests for dinner on Saturday. If I wanted to add some high quality hamburger, how much should I add or would it taste awful?! 🙂
Hi Nancy, I’m so glad you loved it! I’m not quite sure I understand the next request though!
I just pulled this out of the oven! Can’t wait to try it at work tomorrow! Strangely enough, I followed all your instructions to the letter, hunted around Woollies for my roasted capsicum, rather generously layered my things, and I have leftovers of all the layers! Not enough to make another whole one, unfortunately (I couldn’t stop mysef from picking at the veggies while they sat in their roasting tray), but enough to make me consider making wonky cannelloni with the bits and pieces with leftover pasta sheets. Thank you for yet another cracker of a recipe, Nagi! I’m slowly but surely working my way through as many as I can
I have the SAME problem every single time!!
Hi Nagi….. I am a huge fan of yours. I always get some raving comments on the food I make from your recipes. On this one…what can I substite the egg with? Thanks much x
Hi Kamini you could just leave it out if you wanted to – N x
I liked the sound and look of this recipe though didn’t think it would taste as good as it actually. My husband is Italian and a big critic on lasagna and he even approved. Will 100% make again.
Woah that’s a great thing to hear Sally!
I made this tonight for Friday dinner during Lent & we absolutely loved it! I will make again ❤️
Awesome Carolyn!
I have 2 questions for you. What is the difference between raw sugar and brown sugar and are they interchangeable in cooking? Secondly can you explain what you mean by broiling as opposed to baking or grilling. Thanks.
Hi Annie, Raw and brown sugar are very different. Raw sugar is unrefined whereas brown sugar has molasses added to it, so technically they aren’t interchangeable. Broiling is similar to grilling, it’s essentially putting something under a high heat. Whereas baking is a heat source that surrounds the item rather than directional heat ❤️
Hi Nagi, I have just made your meat lasagna (lovely) and have left over sheets. Can the vegetarian lasagna be frozen?
Hi Julie, yes it definitely can!
Thank you Nagi, I have made this recipe again and received very positive comments.
Simple and easy steps to follow with a very taste result.
That’s awesome Susan!
I made this tonight with butternut squash, zucchini, and sweet potatoes…it was yummy!
Yessss sounds fabulous Nisha!
Made this last night…it was very, very tasty. I used frozen cubed butternut squash, which when thawed was too wet and goopy to brown properly in the oven. Won’t use that again! For those of you unfamiliar with the metric system, a 2 cm cube (chopping directions) is about 0.8 inch.
I’m so glad you loved it anyway Janet!
Thanks for this great recipe! I’m going vegetarian for January and this was a delicious option which I made when some (non veggie) friends came for dinner. They loved it! I added some grated cheddar to the top (because hey, why not add a 4th cheese?!) The tomato sauce is brilliant – I’m gonna make that again on it’s own to go with spaghetti or whatever. And now I have left over lasagne for lunches in the office this week 🙂 I’m going to browse your site for more ideas… thanks!
You can never have enough cheese Victoria!!! I’m so glad it was a hit!
Hi I love red peppers in any dish as they give such a flavourful taste. unfortunately my son in law gets indigestion from red peppers.Is there any other veggie you would use as a substitute for recipes? Love your recipes
Thanks
Belinda
Hi Belinda, you can just leave it out ☺️
Hi Nagi, I haven’t tried this myself, but I’ve seen on another site (sorry!) the suggestion of cooking 1/2 cup of lentils to add to the sauce for a “meatier” texture. It sounded like a good idea so I thought I’d share it here.
I’m going to make your lasagna this weekend and give the lentils a try. Can’t hurt, right? ☺️
Oh great idea to “beef” it up a little! Let me know how it goes!
Adding the lentils worked! They didn’t add any flavor but gave the sauce a bit of chewiness associated with ground (minced) beef.
Great to know!!!
That redish (coral?) color works better than the greyscale. LOL. just my opinion tho.
Thanks got the feedback!
Thank you for adding subs. for some of the ingredients ,Seems I usually have all but one. Wish I could take Dozers place for a week, what a great life
😂
Hi Nagi, i’ll try your veggies lasagna and crusted salmon for the olds….and please can you post more of Dozer,! Love your dog too!
I was wondering what to serve to my mostly vegetarian family on Christmas. Your vegetable lasagne looks like a good choice. Thanks for coming to the rescue.
I am going to be brave and try making lasagna for Christmas. Your vegetarian lasagna recipe will be a good guide. Thanks!
Hi, I’m planning to serve this on December 25. How far ahead can I make this?
