What a way to get your veggie fix!! Layers of roasted vegetables, spinach and ricotta, and a homemade tomato lasagna sauce, this Vegetarian Lasagna is one of those foods that is fantastic made fresh and reheats extremely well. It’s Meat Free for Carnivores!
This Vegetarian Lasagna recipe was originally published February 2018. Updated in June 2018 for housekeeping matters. Not change to recipe – I wouldn’t dare!
It is hard to top an epic, meat lasagna made with layers of slow cooker ragu, topped with 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.
This from a self confessed meat lover – that’s a big statement!!
But this is so much more than just the usual vegetable lasagna. It’s the roasted vegetables – hands down, roasting brings out better flavour in vegetables than any other method of cooking (except maybe char grilling). It’s that spinach and ricotta layer. I’m a sucker for spinach and ricotta anything, but woah when you have with those roasted veggies, that homemade lasagna sauce and layers of lasagna sheets…
It’s so good. SO GOOD. There are no words. (And regular readers know what a carnivore I am!)
VEGETABLES FOR VEGETARIAN LASAGNA
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.
Also, 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!
Vegetarian lasagna is made for serving 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

- 1/2 cup / 50 g grated parmesan (or 3/4 cup shredded cheese)
- 1 egg
- 1 garlic clove , minced
- 1/8 tsp grated nutmeg, optional (fresh or powder)
- 1/2 tsp each Salt and pepper
- 1 tbsp olive oil
- 1 garlic clove
- 1 small onion , finely chopped (any, I use brown)
- 700 g / 24 oz tomato passata (Note 3)
- 400 g / 14 oz crushed tomato
- 1/2 cup / 125 ml water
- 3/4 tsp each dried thyme and oregano (or basil, parsley)
- 1/2 tsp dried chilli flakes (can omit / adjust to taste)
- Salt and pepper
- 330g / 11 oz jar roasted red pepper strips, drained (Note 4)
- 375 g / 13 oz fresh lasagne sheets (Note 5)
- 300 g / 3 cups shredded mozzarella (or MORE!)
-
Preheat oven to 200C/390F.
-
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).
-
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.
-
Place ingredients in a bowl and mix until combined.
-
Preheat oven to 160C/320F.
-
Spread a ladle of tomato sauce on the base of a large baking dish (Note 5).
-
Cover with lasagna sheets, tearing as required to fit.
-
Top with roasted vegetables, scatter over red peppers. Spoon over 2 1/2 cups of Sauce, then sprinkle with half the cheese.
-
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.
-
Rest for 5 minutes before cutting and serving. Store leftovers per notes - brilliant reheated!
1. Veggies - feel free to use any vegetables you want, just cut them so they roast in around 20 to 25 minutes. Cauliflower, broccoli, carrots, squash are some I've used in the past.
Pumpkin: 600g/1.2lb unpeeled weight.
2. It's best to get ricotta over the counter at the deli, even at supermarkets, rather than buying in tubs unless it's a brand you know is good like Paesanella. Harris Farms brand ricotta is also good. I find ricotta in tubs at supermarkets is typically grainy and kind of powdery - even the "big" brands (like Perfect Italiano).
3. Tomato passata (called Tomato Puree in America) is pureed tomato, just plain tomato with no flavourings. It is so good for making sauces like this because it's smooth ie no tomato lumps. It comes in tall bottles and is the same price as canned tomato (by weight). Found in the pasta aisle of supermarkets in Australia - it's becoming increasingly popular. I like to use a combination of passata and crushed tomato for for texture and flavour.
If you can't find passata, use the same weight of crushed tomato.
AMERICA: A reader has told me that Tomato Puree is sold in the canned tomato section. What you call Tomato Sauce is a good substitute if you can't find passata. But remember to taste your sauce before adding salt into the sauce as Tomato Sauce already has a touch of seasoning.
4. I really love using roasted red peppers in this for sweetness and extra flavour dimension - the smokey flavour is so good! I use Always Fresh. You could just add chopped capsicum / bell peppers to the roasted vegetables.
5. LASAGNA SHEETS: I like using fresh lasagne sheets sold in the fridge section. If you can only get dried, prepare per packet directions. In Australia, some dried lasagna sheets do not need pre cooking before layering in the lasagna ("Instant Lasagna" or "No Cook").
Difference between fresh and dried lasagna sheets - I prefer fresh (or dried lasagna required to be cooked before layering) because it doesn't absorb liquid while cooking so the lasagna stays really nice and saucy. If using dried instant lasagne, add an extra 1/4 cup of water into your sauce (because the lasagne sheets absorb liquid while cooking). Also I find that lasagna made with dried instant lasagna sheets usually end up with a buckled surface, but doesn't affect flavour.
SUB: Believe it or not, tortillas make an excellent substitute for lasagna sheets!
6. My baking pan is 33 x 22 x 7 cm / 13 x 9 x 2.5".
7. STORAGE: This keeps so well in both the fridge and freezer. Cool before covering, then refrigerate or freeze. Defrost before warming. I just reheat in the microwave, but you can also reheat in the oven.
If making ahead to eat later, I would recommend not topping with cheese. Cover and bake for 25 minutes to bring the flavours together. Cool, then top with cheese, cover and refrigerate or freeze. Defrost if frozen, then cover and reheat in the oven for about 30 minutes at 160C/320F, then remove cover just to brown the cheese (it takes longer to reheat than cooking fresh because it's so dense, whereas making it fresh, the ingredients are warm / hot).
8. Nutrition per serving, assuming 10 servings. 
LIFE OF DOZER
“So, have you packed for Japan yet?”, my friend asked earlier this week.
“Nope,” I responded. “I never pack until the night before.” Because the sight of a suitcase reduces Dozer to this:
Just made this for the first time, so easy to follow the recipe. My whole family loved it, will be definitely making it again.
This is amazing!! One trick I did try with the ricotta sauce (because all I had was the store bought kind and took note of your comment about it being grainy) was that I put all the ingredients except the spinach for the spinach ricotta mixture into my Vitamix and blended it until a very smooth, velvety consistency. OMG, was that good. Then just mixed the spinach in. Packed with flavor.
That’s terrific to hear Karen! Glad you enjoyed this! N x
Just wanted to thank you for this recipe – my group of vegetarian university student friends really loved this dish and now think I’m an amazing chef!! Only alteration I made was pan frying the veg instead using red peppers, courgette, and mushrooms.
Hey – take ALL the credit! 😂
I really want to try this recipe for my family. Personally I love eggplant with pasta. Would eggplant work in this?
Thanks for lots of great recipes!
Oooh YES!
Nagi, this lasagne was divine you have out done yourself! Thank you again I have loved all your recipes so far thank you!
Glad to hear you enjoyed this Paula!! Thanks for letting me know 🙂 N x ❤️
Would adding bechamel sauce in be too much?
Never! 🙂 It would be extra tasty! N x
Nagi, I’m pleasantly surprised how good this dish was!!!! I made this for my Vegetarian friend yesterday. She loved it and I loved it too! I was one of those people who thought lasagna without meat was “ridiculous”… But you proved me wrong…. I will definitely be making this again!!!!! Oh and I added mushrooms to the mix, soooo good. Thank you once again!
Oh I hear you Angie! 🙂 I’m glad this met your carnivore standards – I LOVE that! N x
For the sauce, am I reading it right that it is one whole garlic going in, or is it just supposed to be a clove?
1 clove 🙂 Thanks for that, will fix!
Hi there I really want to make this today then cook
It for a dinner party tomorrow – so rest overnight uncooked in the fridge. I’m in Australia so tend to use the no cook dried lasagne sheets. I’m thinking this should be fine to make ahead so long as it’s fully covered in the fridge and then just add slightly to the cooking time to account for the fridge effect?
Sorry I missed this message, I wasn’t working this weekend. With the dry sheets, I don’t recommend making ahead without cooking, the dry sheets will suck up all the liquid. I would cook it then reheat, it reheats great!
Hi Nagi
I am making my this tonight for a group of 10.
Would it be alright to make late afternoon and then cook later? I’m concerned it may lose its consistency (dry up) if I let it sit for a couple hours before cooking.

Hi Dana! You’re right to be concerned, the lasagna sheets will soak up liquid while it’s sitting around 🙂 Just add an extra 1/2 cup of water into the sauce so there’s slightly more, that way you’re giving the sheets something to absorb while leaving enough for the lasagna itself. Also, be sure to assemble white the veggies are fresh out of the oven because then they’ll steam inside the lasagne while it’s waiting to be cooked. 🙂 And cover straight away after assembling! N x
Yum, yum and YUM! This was soooo good, i actually ate it 4 days in a row. Thank you!
