Reasons To Love This Vegetarian Lasagna

Veg Lasagna Ingredient Overview
I’ve used the vegetables that I think go best in a lasagna – red bell peppers, mushrooms and zucchini. The easiest and fastest way to prepare them is by pan roasting them in some oil with onions and garlic. But you can also roast them in the oven. We also have spinach in the recipe that goes in the spinach ricotta layer. So you really have a ton of veggies that go here!
How to Layer The Lasagna
This is a really simple process and there’s no right or wrong way to do it.
- Brush the base of the casserole with oil (this helps the lasagna from sticking to the bottom)
- Spread a little sauce
- Cover the base with lasagna sheets (this helps to form a base so that the lasagna doesn’t fall apart when you try serving)
- Spread the ricotta spinach mixture
- Place another layer of lasagna sheets
- Add a layer of the vegetables
- Spoon some sauce and cheese over this
- Layer with lasagna sheets, more sauce and cheese and then bake!
Frequently Asked Questions
There are three main layers in this lasagna – spinach ricotta which adds a layer of creaminess, pan roasted vegetables, cheese and sauce. You will need to make three main elements for this recipe, and these can be made ahead, so that all you finally have to do is assemble and bake.
I always buy the no cook lasagna sheets (I use Barilla’s lasagna sheets). The advantage with them is that you don’t need to pre-boil them before using them. They are much easier to handle and cook as the lasagna cooks. You can also use fresh lasagna sheets if you can get your hands on them.
Even though this vegetarian is quite wholesome as is, it tastes really nice with a side of salad or homemade garlic bread to make this an even more filling meal.
This lasagna once cooked, lasts in the refrigerator for up to 3 days and in the freezer for up to a month. You can assemble this lasagna and store it unbaked in the fridge for up to 2 days.

Richa’s Top Tips
- Even though this is a vegetarian recipe, you can easily add shredded chicken or any other protein of your choice to make it more wholesome
- After removing the lasagna from the oven, allow it to rest for about 10 minutes before serving. This will help the cheese settle down, and deliver a clean cut when serving.
This lasagna is all kinds of amazing. And it tastes great out of the oven when it’s warm and bubbly. But an even better thing with this lasagna is that it tastes even better the next day when the layers have had more time to sit together. And if you freeze it and reheat it a month later, it still tastes fantastic! So all I’m saying is, it’s time to make yourself a nice big batch of vegetarian lasagna…right away!

SPINACH RICOTTA FILLING:
- 100 g Spinach, blanched and chopped (Note 1)
- 200 g Ricotta
- 1/2 cup Parmesan, grated
- 1 tablespoon Fresh Cream, optional
- 1/2 teaspoon Salt and Pepper
LASAGNA:
- 12 no boil Lasagne sheets
- 300 g Mozzarella, shredded
Instructions
- Start the sauce so that it can simmer while you prep everything else. Heat oil in a saucepan and saute onions, garlic and carrots. Once the onions are soft, add tomatoes, tomato puree, water, thyme, oregano, sugar, salt and pepper and let this come to a boil. Then reduce the heat to a simmer and simmer for 20-25 minutes till the tomatoes break down and the sauce is thick.
- Heat olive oil in a pan and saute onions and garlic. Add salt and once the onions are translucent, add bell peppers, mushrooms and zucchini. Cook on high heat for 8-10 minutes till the vegetables are cooked and any residual water has evaporated. Season with more salt and pepper if required.
- In a bowl mix together blanched spinach, ricotta, parmesan and cream (is using). Refrigerate till ready to use.
Layering the Lasagna:
- Preheat oven to 180C/ 350F.
- Brush the base of a large baking dish (mine is 12.5 inch by 8 inch) with olive oil. Spoon a ladleful of the sauce at the base and spread it out. Cover the base with lasagna sheets overlapping/tearing as required.
- Add all the spinach ricotta mixture and spread it out. Cover with lasagna sheets.
- Add the roasted vegetables and spread them out. This will be the thickest layer. Add 2-3 ladles of sauce (approx 1.5 cups) and spread it over the veggies. Sprinkle a cup of cheese.
- Layer with lasagna sheets. Add 2 cups sauce on top and spread it out. Sprinkle with remaining cheese
- Bake for 30-40 minutes, until the lasagna is baked through (stick a knife in the middle to check – there should be no resistance) and the cheese is golden on top.
- This is an important step. Let the lasagna rest for 10 minutes before slicing and serving. This helps settle the layers and the lasagna won't fall apart when you serve.
Notes
- Spinach: You can also use frozen spinach. Make sure to thaw it fully and squeeze out all the water before using. Do the same with blanched spinach.
- Pasta: If you are using pasta that needs to be pre-cooked, boil according to package directions. Reduce the cooking time to 25 minutes and then check.
- Make Ahead: You can assemble the lasagna and refrigerate for a couple of hours and bake when required.
- Storing: The lasagna keeps well in the refrigerator for up to four days. Or you can freeze it for up to 2 months.
I’d like to make this recipe but do not like Ricotta cheese. Could I substitute cottage cheese instead?
Hey Carol, I have not tried with cottage cheese yet. Do leave a comment if you give it a try
Amazing recipe! We really enjoyed it:)
Thank you
Wow! You made this one too. Glad you liked it
In the video the last 2 layers show a cheese added that doesn’t look like Parmesan and it looks like there is mozzarella but can’t find it in the ingredients?
Also how long do I reheat the frozen defrosted lasagna for and at what temperature
Hey Laura, Mozzarella is mentioned under the sub heading – Lasagna. reheat in the oven at 180C/350F for 10-15 minutes till its heated well in the centre.
Thank you so much! Have you any suggestions on what i can replace the mushrooms with please?
Hi this lasagne looks amazing! I have read in your notes that this tastes even better the next day. As I’d like to make this for a dinner party, can i put the lasagne together the day before and store it in the fridge to bake the next day?
Yes absolutely! I do that all the time
This recipe was delicious came out so much nicer than expected..the ricotta layer was beautiful 🙂
