What is a Vegetable Lasagna?
Our vegetable lasagna is packed with amazing flavors and textures.
Loaded with fresh vegetables, zucchini, onions, mushrooms, and fresh spinach, as vegetable lasagna, this one is very satisfying and filling.
For this recipe, we make our own tomato sauce from scratch, and prefer a fresh marinara sauce to give this lasagna its yummy fresh taste!
Plus, when you make it with no-boil lasagna noodles and have prepared marinara sauce on hand, this vegetable lasagna comes together in no time.
While it’s loaded with nutrient-dense veggies, cheese, and some cream, you’ll be surprised it has a very light texture to it, creating by far the best-tasting vegetarian lasagna we ever had!

COOK’S NOTES and TIPS for Best Vegetable Lasagna:
This recipe is a 2 step process. The first step is to cook the vegetables, causing them to fully caramelize for more flavor, and the other step is to assemble the lasagna together. You can prepare this lasagna one day before and refrigerate until you are ready to pop it into the oven.
Keep in mind, you will need a lot of prepared marinara sauce on hand. We always make a double batch of our Mom’s Quick Marinara Sauce and keep it in the fridge. You will need about 4 cups or more.
It’s best to rinse the fresh spinach, but do not spin the water out, since it needs the extra moisture while baking.
If you buy pre-washed and already chopped vegetables at the market, it will help save a lot of time in the prep work. Plus, using the no-boil noodles also helps cut the time in half.
You can adapt this recipe, and add some of your favorite vegetables with this lasagna. And make it more cheesy by adding in an extra layer of shredded cheese in between the layers with the vegetables.
Also, I prefer to bake the lasagna without the final layer of cheese on top. Then add the cheese on top for the remaining and final 5 minutes of baking time. This way the foil wrap does not pull off some of the melted cheese when you remove it, ruining the top layer of melted cheese.
This lasagna will feed a large family. And it reheats beautifully.
Best Vegetable Lasagna makes an easy and fabulous meal for the whole family to enjoy!
I made this the other night. This is such a delicious dish. Getting your family to eat more healthy greens like spinach is not always easy, but you can most certainly hide them in this lasagna. It always works for us.
