This ooey gooey Roasted Vegetable Lasagna is so packed full of healthy vegetables, you won’t even miss the meat. The secret is to roast the vegetables first which intensifies the flavours and reduces any liquid so you don’t end up with a watery bottom.
There are all kinds of vegetables that work well in a vegetarian lasagna. You might find lots of seasonal veggies if it’s the right time or year, or, choose what looks good while shopping and make use of what’s in your fridge. As long as you have about 8 cups in total, basically enough to fill a baking sheet, you’re good to go. It sounds like a lot but the veggies reduce quite a bit when roasted and once you have some caramelization, the flavour intensifies.

I like to use any combination of onions, shallots, mushrooms, sweet peppers, eggplant, zucchini, summer squash and of course tomatoes. You can use chopped tomatoes or halved cherry tomatoes or both. Cut everything into similar sized chunks. They don’t have to be too small because they shrink to about half their size. And toss in some unpeeled cloves of garlic too. The peels will protect the cloves from burning. Helpful tip – count how many cloves you add so you remember to remove them from the roasted vegetable mixture.
Scatter the veggies onto a large parchment lined baking sheet. Drizzle lots of olive oil over top and season with salt and pepper, dried basil and oregano. Be patient. It takes about 45 minutes for the veggies to be reduced and caramelized. Give the mixture a stir after about 20 minutes, then watch carefully for the liquid to evaporate and the veggies to be well roasted. Scrape everything, including any juices into a bowl and stir in some pasta sauce. Squeeze the soft garlic out of the cloves and mix that in too. Toss in a few handfuls of spinach while the mixture is warm.
In another bowl combine cottage cheese and an egg. You can use ricotta instead of cottage cheese if you like but cottage cheese is less expensive. The egg helps to bind the layer and also gives it a more fluffy texture so it’s not too heavy. Then grate your mozzarella and add half to the cottage cheese mixture, saving the rest for the top. Toss in some fresh chopped parsley and season with black pepper. Please don’t use low fat cheese. Ever. It doesn’t melt properly and the top of your lasagna ends up looking like melted plastic.
Bring a large pot of water to a boil and add a bit of salt. Lay a kitchen towel on the counter and cook 6 noodles at a time until al dente. By not crowding them in the pot you can ensure they all cook evenly and can remove them quickly before they overcook and start tearing. Cook the next batch while you’re assembling the first few layers.
Spoon a very thin layer of sauce in the bottom of a baking dish. Place 3 noodles side by side over the sauce. Spoon half of the vegetable mixture evenly over the noodles. Cover with 3 more noodles. Spread half of the cheese and egg mixture over top. Lay a third layer of noodles and spread the remaining vegetable mixture evenly over top. Then add 3 more noodles and spread the remaining cheese mixture evenly. Top with the last 3 noodles and spread about a cup of sauce over top. Cover with the rest of the shredded mozzarella. Yes, that’s 15 lasagna noodles.
Since this is a heavy multi layer lasagna, it needs a little more cooking time than a typical lasagna. Adding some foil to the pan for the first part of cooking will help keep the cheese soft while allowing enough time to fully cook the lasagna. You don’t want the cheese to stick to the foil so you can either rub or spray non stick coating on the foil or fold it in a tent shape and just attach the foil to the ends of the pan.
After about 45 minutes, remove the foil and continue to bake for another 40 to 45 minutes until its bubbling around the edges and the cheese is melted and browning. Make sure you rest the Roasted Vegetable Lasagna at least 15 minutes before serving. This helps hold the pieces together better.

Looks delicious!
Read this recipe before I rolled out of bed this morning….which led to French onion and leek soup, then olive and onion bread. They all look amazing! I will definitely be making all 3, at different times of course, when we have company. I’m making your Coq Au Vin at the end of July, preparing most of it prior to a round of golf with Rick and Val and then coming back for dinner, can’t wait!
Wow, I’m so glad to have inspired you!
I have had the pleasure of being invited to your table for vegetable lasagna and it was delicious! I’m going to make it at some point this summer. 🙂
