★ Why You’ll Love this Recipe ★

This layered vegetable lasagna is super easy to make!

This vegetable lasagna gets rave reviews every time yet it’s so easy to make.

With a few shortcuts, this white sauce lasagna comes together quickly.

Here are the two time-saving tricks:

  1. Jarred Alfredo sauce. You want to go with a quality Alfredo sauce that has added flavors like garlic and a blend of cheese. This adds layers of flavors in one step. My go-to Alfredo sauce is Parmesan Roasted Garlic Parmesan Alfredo sauce.
  2. Oven-ready noodles. This saves not only time, but also makes clean up much easier. No noodle pot or colander to clean. The noodles cook right in the lasagna, absorbing extra juices from the veggies which makes these extra flavorful too! Win-win.

★ Ingredients You’ll Need ★

You can use any vegetables in this veggie lasagna but my favorite blend is layers of

and thinly sliced zucchini.

I really enjoy Stouffer’s vegetable lasagna and this is the combination of vegetables that is in their recipe, so that’s what I like to use. You can experiment though and see what tastes best to you!

★ Tips & FAQs ★

What kind of Alfredo sauce is best with veggie lasagna?

I am always amazed at how blending vegetables with cheese can transform into something so delicious! This white-sauce lasagna incorporates jarred Alfredo sauce with extra flavoring, traditional ricotta cheese, a layer of mozzarella and a sprinkle of cheddar cheese.

As I mentioned, I like to use Roasted Garlic Parmesan Alfredo made by Ragu. This sauce has added garlic and Parmesan which really enhances the overall flavor of this dish.

However, you can choose your favorite Alfredo sauce. Just keep in mind, the sauce is key to how this dish will ultimately taste since the veggies themselves are mild in flavor.

White or black pepper — which one is best?

Both work in my opinion. I like the idea of white pepper when I make white sauces because it looks cleaner. But then sometimes I like the look that pepper ads. There’s a flavor difference too though.

The difference between the white and black pepper is that black pepper has its outer shell. Whereas, white pepper is just the inside seed of a peppercorn. Since black pepper contains for the seed and shell, it can add a slightly more complex flavor.

My advice is to go light if you’re using white pepper. Because it doesn’t have the the shell like black pepper does, you are working with just the powerful, peppery inside. So you actually need less of it.

Make two because yes, you can freeze this vegetable lasagna.

This recipe makes two 8″ x 8″ pans, so it’s great if you plan to share with friends and family. Think freezer meals for new moms or new neighbors. Yes, people still do this and certainly appreciate it. Be that person!

Or if you’re in a stage of life where you’re just struggling to get dinner on your own table, I get you! You could serve one lasagna for dinner that night and freeze the other one for a quick and easy weeknight meal another day.

My sister-in-law and I made this alfredo lasagna together and it was so easy that we actually made three others at the same time. We ate two (there was a lot of us!) and then I took two home and froze them, uncooked.

If you freeze yours, then when you’re ready to eat it, just put the lasagna dish into a cold oven to let it warm up as the oven warms. This will prevent the casserole dish from cracking. Still use caution, especially if using glass because glass can shatter if it changes temperature too quickly. It will need to cook for about an hour or until the center is nice and hot if you’re starting with it frozen.

Believe it or not, easy enough for a weeknight dinner!

Reviewers have been surprised exactly how easy this recipe is to make. See for yourself!

Need a casserole dish?

For this recipe, you will need a baking dish that is oven safe. I love the colorful Le Creuset baking pans. They are pricey but they are sturdy. They’re both oven and freezer safe. Pyrex is another good choice. Or use foil baking pans if you plan to give one (or more) away so the recipient doesn’t have to worry about returning your dish.

I used 1 lb well drained frozen spinach and combined with lightly sauteed carrots and onions, for the 3rd layer (raw zucchini and then a layer raw yellow squash as 1st and 2nd). Used no boil lasagna straight from the box. Made in 9x13 pan, baked covered 375 degrees for about 55 minutes, then let it rest before cutting. Make sure to salt and season the squash layers well. Was very easy and delicious, not soggy at all. Will absolutely make again! Thanks for the recipe!

This turned out good! You can make this in an Instant Pot Duo with a bake setting- just cut the noodles in half after boiling. I had layers of blanched asparagus, zucchini, and spinach.

Can you just put uncooked noodles in this instead of buying no cook noodles? I made a lasagna with meat sauce and a recipe just had my layer in regular uncooked lasagnas noodles and it came out perfect.

There are enough juices between the vegetables and the sauce to “boil” the noodles as it bakes, you probably will be fine, but I’ve never tried it.

What are your thoughts about adding some chopped onion to this recipe?

Angela G.

Friday 10th of September 2021

If onions sound yummy to you then I would go for it! I would just sauté the onions first since I’m not sure they would cook long enough in the lasagna if you added them raw. Sometimes I cheat and put chopped onions in a little cup of butter covered up with a wet paper towel so it sticks and put it in the microwave for a minute.

Do I cook the veggies first?

Sunday 18th of July 2021

Hi Chelsea! Nope, you don't need to cook the veggies first. They will cook in the alfredo sauce as the lasagna bakes in the oven.
