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!

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

Roasted Vegetables:

- Place vegetables on the tray, drizzle with oil, sprinkle with garlic, salt and pepper. Toss.
- 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.*
- Remove from stove and let cool for 5 minutes before using.

Lasagna:

- Cover with lasagna sheets. Spread over Ricotta mixture.
- Cover with lasagna sheets. Pour over remaining sauce and sprinkle with remaining cheese.
- Bake for 25 - 30 minutes or until the cheese is golden. If using dried lasagna sheets, stick a knife in the middle to ensure it's cooked - if it needs longer, cover and stick it back in the oven.

Hi Nagi,
I tried this recipe tonight for my husband and I. It was absolutely brilliant. I have struggled to make a good lasagne for a while . I am glad I came across your recipe! You are the only food blogger I follow! I hope you and your family have been well.
Thanks,
Denita
This was a fantastic recipe Nagi! Thank you for giving me a fun afternoon of cooking in lockdown. The jar roasted peppers were a great flavourful touch. Have already shared the recipe around 🙂
The veggie lasagna was delicious. I used butternut squash instead of pumpkin. I will definitely make it again.
thanks Nagi!
Loved this! Took my pasta a la fridge to a new level. I bought ricotta when it was on special and didn’t know what I’d make with it. I had everything at home already, other than passata (just used two tins of crushed tomatoes and scaled recipe to feed four), and it was super easy to make off the cuff. I normally use your slow cooker bolognese to make a meat lasagne and my partner said he couldn’t pick a favourite. Leftovers for him tomorrow and a little sauce left to make parmas for dinner during the week. Haven’t made anything from your site that we haven’t loved! Thank you, thank you, thank you!
Hi Nagi. I made this lasagna but there was so much liquid in the bottom of pan. I’m not sure what I did wrong. I roasted my veggies and made homemade marinara. Still delicious but I m perplexed
Can mozzarella be substituted with other cheeses (pepper jack or cheddar)?
Yes 100% Marie! N x
Hi Nagi, I made this Lasagna for Easter Sunday, as well as a meat lasagna, it was a great hit with my family. I will be keeping this recipe in my favourites. Thank you
I discovered your site 2 weeks ago and have tried 5 recipes so far. All of them were so delicious. Nagi, I love your dishes – so glad to have found you! The vegetarian lasagne was just lovely :-)!!
That’s great to hear Tanja, thanks so much for the amazing feedback!! N x
I made this for dinner last night – including the spinach ricotta layer. It was far and away the BEST veggie lasagne I’ve tasted. The family all raved too & there’s plenty left over the next day – Thanks Nagi!!
I don’t know why I doubted this would be anything but delicious. I subbed the ricotta for cottage cheese and used grated Gouda instead of Parmesan. Couldn’t get a hold of roasted red pepper strips so just roasted some red capsicum as suggested in the notes. It was quite wet at the bottom of the baking dish but delicious nonetheless. Will definitely make this again!
Another winner. It’s soooo tasty. I made this a week ago along with lots of other meals I was preparing, portioned it up and froze it for easy lunches/dinners. Had some for lunch today and loved ever bite. Definitely a staple of mine now.
Was amazing and my fiancé enjoyed it and he is a meat eater
My kids love your beef lasagna with a white sauce but now I have a vegetarian in the house. We’ve made your veggie lasagna lots of times but the girls aren’t struck on ricotta. What do you think of replacing the ricotta layer with a white sauce?
You could definitely do that instead Roshelle! N x
How would this go with adding tinned lentil in with the veggies? Or should I look for a different recipe?
Hi, I have made this recipe many times and always add tinned lentils (or brown lentils soaked overnight) and it is absolutely delicious.
I was wondering hone many days in advance I could make this? If I were to assemble on a Friday, and put in the oven on lunch Sunday, would it still be ok?
