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

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

Life of Dozer
Whenever I go away, I never pack until the night before. Because the sight of a suitcase reduces Dozer to this:

HI, Nagi,
In the States, we call tomato passata tomato purée. It is found with all the other canned tomato products, and it is just plain tomato — no seasoning — so I think it is the same thing.
Can’t wait to try this one!

Thank you for the tip Donna! I will update the recipe notes 🙂 N x
Ohhhhhh!! That makes me tear up. Poor Dozer!! He knows. *sigh* And frankly, Miz Nagi, you are torturing me with that lasagna!! All that ooey, gooey cheese. YUM!! You’ve convinced this carnivore to indulge in your huge square of lasagna. When may I expect it??? I won’t eat anything until it gets here. I want to make sure I’m good and hungry. What wine would you recommend?? Sending Hugs!!
Tears you up?? NOOO! Dozer is spoilt rotten and you know it!!
Oh this looks good. I’m a take-it-or-leave-it meat gal, so this lasagna is very appealing to me. That dog!!!
He’s such a drama queen!!!
I just joined you yesterday.
Thank you very much for the 3 free cook books.
I know I will be making many of your recipes.
Your tastes and methods parallel mine.
I live in Illinois, USA, Half way around the world from you.
I started gardening 4 years age when my mother-in-law (then 97 years old) decided shee would give up gardening.
I told her not to worry, I would grow whatever she wanted….so here I am.
She passed away at age 101….but I am holding up her legacy (I am 72 years old, presently).
Gardening and cooking go hand-in-hand.
I am using Eliot Copleman’s 4 season methods. I have 6 hoop houses, as well as open soil crops.
I especially like asian greens, peppers, and tomatoes,
Keep up your good work, and Have a wonderful 2018,
