Eggplant Polenta Lasagna is a vegetarian lasagna dish made with polenta instead of noodles and eggplant and mushrooms for additional veggie goodness. 15 minutes of prep are all you need to make this delicious lasagna-like dish!
Do you ever impulse-buy something at the grocery store and then not have any idea what to do with it? I do that from time to time, and it always makes me laugh at myself.
That is what happened with this prepared polenta that I bought. I had served polenta before, but it came frozen from Trader Joe’s as part of a prepared side dish. All I had to do was microwave and serve!
So this tube of prepared polenta that I bought on impulse was a completely different animal. It sat in my pantry for a couple of months, because I didn’t have a plan.
One day I was working on a recipe for a lasagna with eggplant, and it hit me that the polenta would make a great addition to that dish! So I put it all together, and it was a huge hit with the family.
The polenta added a nice texture and mild corn flavor that perfectly complimented the eggplant and mushroom flavors and did not overpower the cheese and sauce.
My favorite part of the dish, however, was that I totally skipped the hassle of dealing with lasagna noodles!
Thing 2 is very sensitive to textures in his food, so I did roast the eggplant ahead of time to insure that it would be soft enough in the lasagna, and I also cooked the mushrooms a bit in the microwave for the same reason.
However, if you like your mushrooms to have a little more substance, you can probably skip that step altogether.

The way you wrote the instructions for the recipe is brilliant. I’ve never seen anyone include the amount of the ingredient into the instructions. Can’t wait to make this recipe, I’ve been looking for a while to make some thing that included ricotta. Probably going to roast the sliced eggplant and polenta before I put the dish together.
So glad you find the recipe format helpful! And I hope you enjoy this recipe. I actually have it planned for my family later this week too!
I'm living in Vietnam at the moment, with no access to pre-made polenta, but I do have a package of dry. Can I assume that the pre-made polenta is just that, someone else made and it's like "day old"? So therefor, I can just make some polenta and then the next day use it in your lasagna recipe? Thanks!
I think that is totally worth a shot! Good luck and let me know how it turns out. 🙂 Thanks for stopping by!
