Mushroom Polenta Lasagna

This name is a lie. There is not a stitch of pasta in this recipe, so I don’t want to lead you astray. Instead, you layer the ingredients like a lasagna. Yes? We’re on the same page? Yay! Cause it’s SO tasty.

This recipe is brought to you by Food Network magazine and feeding guests, which I LURVE.


I was a dummy and took a picture of this BEFORE it baked, which is a shame, because it looks lovely when cooked– the cheese gets melty and browned and the whole dish is bubbly.

  • Note: This recipe fed four of us, and provided at least 1 leftover serving for each of us. So, let’s just acknowledge, this makes A LOT OF FOOD.

For the sauce:

  • 1 ½-ounce package dried porcini mushrooms, rinsed (I had just a dried wild mushroom mix. These are worth buying, because you can use dried mushrooms for mushroom risotto and other recipes as well.)
  • 3 tablespoons unsalted butter
  • 3 tablespoons extra-virgin olive oil
  • 1 pound button mushrooms, trimmed and quartered (I prefer cremini)
  • 1 pound shiitake mushrooms, stems removed, caps quartered (If shiitake are too expensive, just reduce the amount of shiitake and up the regular mushrooms, but don’t leave out the shiitake altogether because they really make the recipe.)
  • Kosher salt
  • 1 small onion, chopped
  • 2 cloves garlic, minced
  • ¼ teaspoon red pepper flakes
  • 3 tablespoons tomato paste
  • 1 15-ounce can whole San Marzano tomatoes, crushed by hand (or whatever means you like, I use an immersion blender or a fork)
  • ½ cup chopped fresh parsley, plus more for topping (optional)

For the lasagna:

  • 2 ½ cups instant polenta
  • Kosher salt
  • 1 cup grated parmesan cheese (about 4 ounces)
  • 2 large eggs, lightly beaten
  • ¼ teaspoon grated nutmeg
  • Extra-virgin olive oil, for the baking dish
  • 3 cups grated part-skim mozzarella cheese

Make the sauce: Soak the dried porcini in 3 cups hot water, 30 minutes. Drain, reserving 2 cups of the soaking liquid. Roughly chop the porcini.

Heat 1 tablespoon each butter and olive oil in a large pot or Dutch oven over medium-high heat. Add half of the button and shiitake mushrooms and cook, undisturbed, until slightly browned on the bottom, about 2 minutes. Continue to cook, stirring, until soft, 2 to 3 more minutes; transfer to a bowl. Repeat with another 1 tablespoon each butter and olive oil and the remaining button and shiitake mushrooms. Transfer to the bowl and add ½ teaspoon salt.

Reduce the heat to medium and add the remaining 1 tablespoon each butter and olive oil to the skillet. Add the onion and porcini and cook, stirring, until the onion is soft, about 4 minutes. Stir in the garlic and red pepper flakes. Add the tomato paste and cook, stirring, until darkened, 1 to 2 minutes. Add the reserved 2 cups porcini liquid, the crushed tomatoes, button and shiitake mushrooms and ½ teaspoon salt. Bring to a simmer and cook, stirring occasionally, until thickened, about 30 minutes. Remove from the heat and stir in the parsley; season with salt.

Prepare the lasagna: Bring 7 cups water to a boil in a large saucepan; transfer to a large heatproof bowl. Meanwhile, bring 3 cups water to a boil in a separate large saucepan. Gradually whisk the polenta and 1 ½ teaspoons salt into the bowl of hot water. Cover the bowl tightly with foil and set over the saucepan of boiling water. Reduce the heat so the water is simmering; cook the polenta until the liquid is absorbed, about 15 minutes. Remove from the heat, uncover and vigorously whisk in the parmesan, eggs and nutmeg. (I just cooked polenta like I normally do. Two cups of water to each cup of polenta. Or, 1 cup milk, 1 cup polenta, for richer, creamier polenta.Then, added parm, eggs, and ground nutmeg.)

Preheat the oven to 350 degrees F. Lightly brush a 3-quart baking dish with olive oil (or just spray with cooking spray). Spread one-third of the polenta in the dish and top with half of the mushroom sauce. Sprinkle with 1 cup mozzarella. Repeat the layers (polenta, sauce, mozzarella), then top with the remaining polenta. (If the polenta gets too thick, whisk in a little hot water.)

Loosely cover the dish with foil and bake until bubbly, 50 minutes to 1 hour. Turn on the broiler. Uncover the lasagna and top with the remaining 1 cup mozzarella; broil until melted, 2 to 3 minutes. Sprinkle with parsley. Let stand 15 minutes before serving.
