I love lasagna but we have a rule. Christmas day only. We call it Christmas Lasagna. However, I thought if I could replace some pasta with vegetables, we could eat it more frequently. Substituting layers of lasagna pasta are actually easier than you think. The trick I found, is to use the actual pasta on the top and bottom layer, but the middle layers can be lasagna noodle substitutes, and people will really not notice.
So the first thing I did before creating this vegetarian lasagna recipe with pasta substitutions was to look around at what was already out there. What I found when I searched for sweet potato lasagna recipes seemed more like a sweet potato casserole and less like lasagna. So I just read over a couple of options and then came up with my own pasta alternative, while still using some pasta for the top and bottom so that the lasagna really feels like it is real.
This was risky because it was for my daughter’s birthday, and I was winging a recipe I’d never made before. Her requirements are rather odd because she is 90% a vegetarian (prefers it, but sometimes eats meat for protein) and she tries to eat very healthily, which means low quantities of refined pasta.
What we ended up with is lasagna with top and bottom real pasta, and two layers in the middle where sweet potatoes are the pasta replacement. By lightly salting the sweet potatoes at each layer with a light amount of coarse salt, the layers ended up being sweet and salty, instead of just sweet.
If you do not want sweet potatoes, I am sure you can think of many other lasagna pasta substitutes. For example, zucchini would work, squash would work, eggplant, thinly sliced shiitake mushrooms, corn tortillas, and even regular potatoes (although more healthy???) are all possibilities as a lasagna noodle substitute.
Whichever pasta alternative you choose for your lasagna, the key is making every layer tasty and stacking it well. It will all bake together beautifully. And since we use real lasagna pasta on the top and bottom, there is a chance no one will even notice that the center is actually layers of vegetables.
The good news is, this being my daughter’s birthday dinner turned out great. She said it was the best lasagna she has ever had. I would not go that far, but I am more partial to it billed with meat sauce and mushrooms. However, for a more healthy lasagna with vegetable substitutes for more than half the pasta, it was surprisingly good and having a second piece was guilt-free.
Just a warning on the pictures, I am using stock photos because I did not take any during the first round of making this dish. Trust me, the layers looked great and the only time you really noticed the sweet potatoes is when you would eat one layer and they would be exposed below it. When you actually look from the side at a cut slice, it looks identical to lasagna full of pasta, and not some special pasta alternatives.
