As a proponent of a sustainable lifestyle, I am always trying to make eco-conscious food choices. One easy way to improve your ecological footprint is by finding ways to enjoy more meatless meals.
Green tip: Industrial meat production has a huge impact on the environment, especially because of the amount of land it takes to sustain and its high amount of greenhouse gas emissions. Reducing your meat consumption is one great way to reduce your ecological footprint.
Meatless Lasagna Ingredients
Here’s everything you need:
- Lasagne. You’ll only need 9-12 whole noodles (depending on the brand). You can opt to get the oven-ready kind!
- Onion. Yellow is preferred but you can also use Vidalia, sweet onions, or red onions.
- Mushrooms. White button or baby bella. If you’re not a mushroom fan consider peppers or squash.
- Spinach. Or any other greens.
- Garlic. Fresh garlic is always best!
- Olive oil. To cook your vegetables in.
- Salt & pepper. To amp up the natural flavors.
- Marinara or spaghetti sauce. Use your favorite!
- Ricotta. Whole milk or part-skim both work.
- Italian blend. Shredded cheese that’s typically a blend of provolone, asiago, mozzarella, parmesan & romano.
- Grated parmesan. To finish off your lasagne with a crunchy, salt top.
Tested Substitutions
This meatless lasagna is a great opportunity for a clean-out-the-fridge meal! I’ve made this same lasagna with tons of different veggies that I need to use up before they go bad.
Some of my favorite alternatives to mushrooms in this dish are red and/or green peppers, yellow squash, zucchini, and eggplant. I’ve also switched up spinach for kale, arugula, and Swiss chard with great success.
If you want a lighter lasagna, you can opt for part-skim ricotta or even sub in cottage cheese. Fat-free shredded cheese also works here.
Green tip: Did you know that of the billions of pounds of food wasted annually, it is estimated that 50% of it happens in our homes? It’s always best to avoid food waste as much as you can!
Why No Egg?
Lasagna recipes often call for an egg to mix with the ricotta to stabilize it. While this does make more even, sturdy layers in your lasagna, I can confidently say that it brings little change to the actual taste.
I leave the egg out simply because I find it unnecessary. A rustic lasagna is still a very delicious lasagna!
Eggs have a higher associated environmental impact, so I love to save them for dishes like Smoked Salmon Eggs Benedict, or French Toast, where they have a higher impact.
Meatless Lasagna Tips and Tricks
Cook the Lasagne First
The first step is to cook the lasagna noodles al dente according to the directions on the box.
Alternatively, if you don’t want to boil your lasagne, you can soak it in hot water for about 30 minutes. You can also opt for the “oven-ready” noodles to save on time (and water!).
Green tip: Don’t waste your pasta water, use it to water your plants! So long as it’s not salty, the starchy water helps fertilize plants and help them grow.
Once I strain the pasta water, I like to spread my noodles out on a baking sheet in a single layer, so they cool quickly and don’t stick to one another.
Cook Down the Veggies
This step is vital to getting a meatless lasagna that is not too watery! Add the onion, mushroom, spinach, and garlic to a large saucepan and saute in the olive oil, salt, and pepper.
Cook the vegetables over high heat, stirring frequently, until the liquids release and evaporate (about 15 minutes).
Layer the Bottom with Sauce
Start by adding a very thin layer of marinara or spaghetti sauce to the bottom of your casserole dish. This will ensure that the noodles don’t overbake and get hard.
It will also make slicing and removing your lasagna from the casserole dish easier, creating a non-stick layer at the bottom.
Meatless Lasagna Assembly
After your thin layer of sauce, add a layer of cooked lasagne noodles. You should be able to fit 3-4 noodles easily in your dish (depending on the pasta brand).
Next, add roughly half of the ricotta cheese. Then, add half of your cooked vegetables. Lastly, another layer of sauce.
Repeat this exact pattern twice before moving on to your top layer. You should use up all of the ricotta and veggies in your two bottom layers.
Finish Off with Parmesan
After two packed layers, finish off with a third layer of pasta, then more sauce. Now it’s time to make your extra cheesy top coating.
Add the rest of the shredded cheese on top and then fill in the gaps with grated Parmesan until the top layer is completely covered with cheese.
Should You Have Leftovers
This is a hearty casserole that’s meant to feed a crowd, so you may find yourself with leftovers. The great news is, that this meatless lasagna will last 3-5 days in an airtight container in the refrigerator.
You can also opt to freeze the leftover lasagna for up to 3 months. Allow it to thaw overnight in the refrigerator before reheating.
To reheat, you can use the oven (preferred method) or the microwave.
The best way to reheat meatless lasagna is to preheat the oven to 350°F and cover with aluminum foil. Bake for about 30 minutes or until heated all the way through (time will vary depending on the amount).
You can also just microwave individual portions on high for about 2 minutes (make sure the very center is hot).

Pro Tips
- *The width of your lasagna noodles may vary slightly depending on the brand. Most brands will only require 9 noodles (three for each layer), but some are not as wide and may require 4 noodles per layer (12 total).
- I like to spread my noodles out on a baking sheet in a single layer, so they cool quickly and don’t stick to one another.

I’m so glad you enjoyed! Thank you so much for taking the time to leave your feedback 🙂
We love this lasagna recipe- very yummy! And we sometimes double the amount of veggies. But am I right I’m thinking that you only use 9 lasagna noodle because you have 3 layers- each layer using 3 noodles…?
Hi Samantha! So glad you love!! Yes, you are correct. 9-12 noodles depending on the brand of noodles you buy (some are slightly wider than others!) I’ll make a note to make sure that’s more clear 🙂 thank you so much for taking the time to leave your feedback 🙂
Oh, and one more thing I noticed since I made the recipe again today
You mentioned in step 9 doing a third layer of sauce, but doing a second layer is never noted in the instructions because for the second layer your have us repeat steps 4-7 but sauce is in step 3 ☺️- hope this makes sense
Thank you SO SO much!!! All fixed.
