You know I really like a recipe when I make it two days in a row. I first made this dish for dinner last night, and though I liked it and my husband thought it was “outstanding,” I still wanted to tinker with the recipe. It was good, but I thought it could be incredible. So this morning I got to work, making a couple of small changes, and boy am I glad I did. A good recipe got even better—and I got an amazing lunch!
Like Rustic Red Kale and White Bean Soup, this recipe is a devious attempt to get you to eat your leafy greens. Kale and portabella mushrooms are sautéed with garlic and then mixed with a creamy “cheese” sauce before being baked between two layers of polenta. (Fans of my Eggplant Parmesan will recognize the sauce from that recipe.) Despite the long list of ingredients, this dish is pretty easy to put together, especially if you use packaged polenta and jarred marinara sauce. You’ll probably spend the most time preparing the kale, but you can even cut out that task if you substitute bagged spinach instead.

(click for printer-friendly version)
If you use packaged polenta, slice it into 18 thin slices. If you make your own polenta, spread the cooked polenta out on a baking sheet and use a spoon or your moistened hands to spread it no thicker than 1/4 inch. When it has solidified, either cut it in half and use each half as one layer or cut it into an even number of pieces that you can fit together to fit your baking dish.
1 18-ounce package prepared polenta or 1 recipe of Quick Microwave Polenta
1/2 large onion, chopped
1 large portabella mushroom, cut into 1/4-inch pieces (about 2 cups, chopped)
4 cloves garlic, minced or pressed
1/2 bunch kale (about 8 ounces after trimming), center rib removed and chopped into bite-sized pieces (may substitute spinach or other greens)
1 teaspoon dried basil
salt and pepper to taste
Cheese sauce (below)
1 1/4 cups marinara sauce (homemade or in a jar)
1/4 cup pitted kalamata olives, chopped
vegan soy parmesan
“Cheese” sauce:
1/2 cup extra-firm silken tofu
1/2 cup unsweetened soy milk
1/2 cup vegetable broth
2 tbsp. cashew butter or tahini
1 tsp. onion powder
1 1/2 tbsp. nutritional yeast
1/2 tsp. salt (optional)
1/8 tsp. white pepper
2 tsp. corn starch
Preheat oven to 375° F. Spray the bottom and sides of a 8×8-inch baking dish with non-stick spray and set aside.
Place the cheese sauce ingredients into a blender or food processor and puree until completely smooth. Set aside.
Sauté the onions and portabellas in a non-stick skillet until the mushrooms begin to exude their juices. Add the garlic and sauté for one more minute.
Add the kale, basil, and 1/4 cup water. Sauté until the kale is wilted and tender and the water has evaporated. Add the cheese sauce and cook, stirring, until thickened. Check seasoning and add salt and pepper if needed. Remove from the heat.
Cut the polenta into 1/4-inch thick slices. Line the bottom of the baking dish with half of the slices, overlapping slightly if possible. Spread 1/2 cup of the marinara sauce over the polenta, and then spread the kale mixture over the sauce. Sprinkle the chopped olives over the kale and top with the remaining polenta. Spread the remaining marinara sauce over the top and sprinkle with soy parmesan.
Bake for 25 minutes. Remove from oven and allow to cool for 5 or 10 minutes before serving.

Amazing! I loved this, and I wasn't even a lasagna lover back in my omnivorous days. I too made some modifications: used quick microwave polenta, omitted the parmesan, opted for spinach -kale is quite difficult to find here in Spain- and made a cauliflower sauce instead of the "cheese" one.
The result was fantastic. I didn't eat the whole pan myself, but I definitely had more than one serving!
this was our second recipe to make from this website (made the refried black bean soup last night). LOVED both! the kids enjoyed the black bean soup, but my partner and i (both vegetarian) absolutely ADORED the polenta lasagna!! fantastic! couldn't get the kids to try the "circle" stuff (polenta), however.
Just tried this tonight – beyond delicious! I made my own polenta (first time) and your recipe made it quick and easy. The cheese sauce is really delicious (I 1/2 the tahini to reduce the fat I figured I wouldn't know the difference).
Thank you for yet another great recipe!!!!
I made this tonight and it was amazing. I love the cheese sauce! This is the first vegan cheese sauce I’ve made that doesn’t have a funny aftertaste. I used spinach instead of kale and extra tomato sauce. I will be making this regularly for sure. Thanks so much for this great recipe!!
I made this recipe last night as well as the oat bars! Oh my goodness! I’ve been talking about this lasagna all day!
I followed your instructions and I loved the cheese sauce it was also my first attempt at cheese sauce and polenta. My daughter even had seconds and she is definitely NOT into polenta
I had it after my Sunday leftovers ( hey I had to taste it, LOL) took it to work for lunch and had it again for dinner tonight! Yep, almost half the pan is gone! Thanks for such great recipes!!
Any ideas for substituting the tofu? I read about mashed white beans in another post but was looking for something creamier and I don’t usually eat soy. Thanks!
Mmm.. made this last night and it was delicious. Hubby liked it too! Looking forward to having it for lunch today. Made it all from scratch which made it a little more intensive than I was bargaining for. Used Alton Brown’s method of baking the polenta which worked wonderfully and made the marinara from Russell James’ Salsa Finta: http://therawchef.com/therawchefblog/salsa-finta-almond-polpetta. The marinara was amazing, especially once it baked into the lasagna.
Joy – if I had to substitute, I would use almond milk for the soy milk and soaked cashews for the tofu. Soaked/blended nuts are pretty creamy.
I’ve made this dish a couple of times and it’s always been a super-duper hit! Fabulous job Susan!
Question: I’m not particularly fond of olives…any recommended substitutes?
Glad you like it! The olives are just there to add flavor, and if you don’t like the flavor, I would just leave them out.
I just made this, well, I made the idea without listening at all, but it was awesome. http://chef.blogs.smugmug.com/2010/07/11/wrong-sized-food-is-fun/#ffv
Awesome recipe! This one is going to become a staple! Thanks!
Loved this lasagne! Made it with broccoli rabe instead of kale, made my own polenta (first time), used green olives (all I had on hand) and a little extra tomato sauce. The cheese sauce was great – one of my biggest challenges is eliminating cheese…thanks for the recipe.
