One of the first recipes I made when I became a vegetarian

This is one of the first vegetation recipes that I started making. I’ve been vegetarian for almost 30 years at this point. (Just about one month shy right now.) So, that’s a long time that this recipe has been around.

I’ve made a couple of changes to it over the years, but the recipe itself stands the test of time, and remains one of my favorites.

Freezer meal & leftovers

This veggie lasagna makes a great freezer meal as well. And, with lots of leftovers from the big casserole, you can package up individual portions, freeze them, and they are ready to go for another meal.

This is also the kind of dish I like to make for others who can’t cook for themselves. Like someone who just came home from the hospital. Or, a new mom. Just make this lasagna in one of those disposable aluminum pans, and they don’t even have to return the pan to you when they are done.

Lasagne vs. lasagna

In doing a little research for this post, I came across a reference to lasagne on Pinterest.

That made me a little curious. My mom used to use the word lasagne. And I wondered what it meant. Or, was it a variation on the same, or just an archaic spelling.

Turns out that the word lasagne is simply the Italian plural for lasagna. Well, that’s pretty easy.

What kind of onion should I use?

Feel free to use kind of onion in this recipe.

I prefer yellow onions, sweet yellow onions if I can get my hands on them. I like the sweet ones for how they caramelize and their overall flavor.

Red onions and white onions will work equally as well in this recipe.

So, don’t fret if you go to the fridge to find that you are out of yellow onions. Just use another kind.

How to chop zucchini

I thought I’d share how I chop the zucchini.

I cut them in half lengthwise, and then into quarters lengthwise. So I have 4 long strips. Then, chop those strips into thin slices.

They are easier to chop this way, and require less work than slicing them and then quartering the slices.

No boil lasagna noodles

I love using these no boil lasagna noodles. So easy.

You don’t have to precook them, just drop them into the layers of the casserole.

When I first started making this recipe all those years ago, no one carried no boil lasagna noodles. So, I made it with regular lasagna noodles.

Now, I will admit that regular lasagna noodles with their wavy edges are really pretty. Prettier than the no boil ones. But for convenience, I’ll go with no boil any day.

If you prefer the regular wavy lasagna noodles, you can use them in this recipe. It’ll still be nine noodles. I actually used to always cook a couple extra lasagna noodles, just in case they tore apart too badly during cooking and they were no longer usable in the lasagna.

Canned crushed tomatoes

One of the changes I’ve made to make the lasagna a little soupier (and allow the no boil noodles to cook properly), was to make a small swap in the tomatoes.

My original recipe called for a 28-ounce can of whole tomatoes that you drain and chop.

Well, besides being extra work to drain and chop them, my husband doesn’t care for chunks of tomatoes, so the crushed tomatoes in my updated recipe works so much better on so many levels.
