Layered Eggplant and Polenta Casserole

Look for precooked polenta logs in the refrigerated section of your grocery store. If using fresh plum tomatoes, peel them by scoring an X in the bottom with a paring knife and plunging them into boiling water for several seconds; transfer to an ice bath, and let cool. Slip off and discard peels and seeds.

  • 2 tablespoons extra-virgin olive oil
  • 1 yellow onion, cut into 1/4-inch pieces
  • 4 cloves garlic, minced
  • 2 pounds fresh or canned plum tomatoes, peeled and chopped
  • 1/4 teaspoon coarse salt
  • 1 tablespoon balsamic vinegar
  • 3/4 cup loosely packed basil leaves
  • Freshly ground pepper
  • 1 1/4 pounds medium eggplant, sliced into 1/4-inch rounds
  • 1 (16-ounce) log precooked polenta, sliced into 1/4-inch rounds


  1. Preheat oven to 400 degrees; with rack in upper third. In a medium saucepan, heat 1 tablespoon oil over medium heat. Add the onion and garlic, and cook, stirring, until soft and lightly golden, about 8 minutes. Add tomatoes and salt, and cook, stirring occasionally, until sauce has thickened, about 30 minutes. Stir in vinegar, oregano, and basil; season with pepper. Remove sauce from heat.

  2. Meanwhile, heat a large cast-iron skillet or grill pan over medium heat. Lightly brush eggplant slices with the remaining tablespoon oil. Working in batches, lay slices in skillet in a single layer; cook until browned and they begin to soften, 2 to 3 minutes per side. Transfer to a plate.

  3. Spoon about 1/2 cup tomato sauce into a 9-inch square baking dish, spreading to coat evenly. Arrange eggplant slices snugly in a single layer. Spoon about 1 cup tomato sauce over eggplant, and arrange polenta rounds in slightly overlapping slices on top. Repeat with sauce and another layer of eggplant. Finish by dotting with remaining tomato sauce.

  4. Cover with foil; bake until bubbling and juicy, about 30 minutes. Remove foil; continue baking until sauce is lightly caramelized and eggplant is tender, about 15 minutes more. Remove from oven; let cool slightly, and serve.

    Again, very easy with a high impact in deliciousness. My only criticism is that, for a one-dish-meal, it lacks the level of protein needed to really leave you with a full feeling. I added a little mozzarella to the layers. Next time I make this, I'll add a little more protein.

    Good recipe! I used a couple jars of organic muir glen pasta sauce to make things go faster.. Turned out great! Also added sun dried tomatoes to the sauce. I made two batches so i could freeze one for later.

    I agree with the ease and it surprisingly was delicious! I used fresh plum tomatoes instead of canned. I made the tomato sauce ahead of time which made it a breeze when layering for the casserole :)

    This was very easy to make and it was delicious. I added diced celery and carrot to the tomato mixture for a little extra flavor.
