Ingredients
- 3pounds globe eggplant, cut into ¼-inch- to ½-inch-thick planks
- ⅓cup extra-virgin olive oil
- 1½teaspoons dried oregano
- Kosher salt and black pepper
- 1(10-ounce) package frozen chopped spinach, thawed
- 1½cups part-skim ricotta cheese
- ⅔cup grated Parmesan
- ⅓cup chopped fresh basil or parsley, plus more for serving
- 1large egg, lightly beaten
- 1½teaspoons finely grated lemon zest
- ¼teaspoon red-pepper flakes
- 1(24-ounce) jar marinara sauce or 2½ cups homemade
- 1½cups shredded low-moisture mozzarella cheese
Preparation
- Step 1
Heat oven to 425 degrees. Line 3 sheet pans with parchment paper and arrange the eggplant planks in an even layer. Brush all over with oil and sprinkle with oregano, 2 teaspoons salt and 1 teaspoon pepper. Roast for 20 to 25 minutes, flipping the eggplant and rotating the pans halfway through, until tender and lightly browned.
- Step 2
Meanwhile, make the ricotta filling: Squeeze the spinach over a strainer to remove as much moisture as you can, then place in a medium bowl. Add the ricotta, ⅓ cup Parmesan, the basil, egg, zest, red-pepper flakes, ½ teaspoon salt and ¼ teaspoon pepper; mix well.
- Step 3
Spread ½ cup marinara sauce in a 9-by-13-inch baking dish. Arrange one layer of eggplant on top, cutting pieces to fit any gaps if necessary. Dollop about half the ricotta mixture on top and use a spatula to spread it evenly over the eggplant. Top with ½ cup mozzarella cheese.
- Step 4
Spoon 1 cup marinara over the cheese, then top with another layer of eggplant slices. Dollop the remaining ricotta mixture on top, spreading it over the eggplant, then sprinkle on another ½ cup mozzarella.
- Step 5
Spread the remaining 1 cup marinara on top, then follow with a final layer of eggplant. Top with the remaining ⅓ cup Parmesan and the remaining ½ cup mozzarella.
- Step 6
Bake, uncovered, for 30 minutes, until the cheese is browned and the sauce is bubbling.
- Step 7
Cool for at least 10 minutes to allow the lasagna to set, then sprinkle with more basil. Use a sharp knife to cut the lasagna into squares and serve hot.

Rather than use frozen spinach, which I find tastes like iron, I chop fresh spinach and stir into the ricotta - no blanching or wilting needed. Works well, tastes great and no excess water.
I find frozen spinach to be bitter. So when making lasagna, I will pour the pasta water over fresh spinach to wilt. In this case, I would use the electric kettle to boil water to wilt the spinach in a colander. The spinach also has less water to squeeze out.
This is very similar to the way my beloved Italian grandma made her eggplant parmigiana. She did bread the eggplant before roasting it and there was no ricotta. But she layered it like a lasagna with very thin layers of eggplant. She passed away at 101 last year.
After baking the eggplant at 425 do you then also bake the constructed dis at 425? Seems pretty high temp. Plan to make soon, responses appreciated!
Not one for red pepper, I stirred in half of a sautéed red onion for a little more kick. And because I like my lasagna with noodles, I added two pre-cooked layers to the dish 😊
Breakthrough! After making this several times and turning it into eggplant casserole when trying to cut it, I cut it before I put it in the oven when the cheese was much more firm. I used a serrated, pointed knife, like a steak knife, and carefully sawed through the layers of eggplant. When it was done, the cut lines were still clear and it was easy to lift out the sections with a spatula. Your guests will all get the same size piece (I made 12 pieces), but it won't get destroyed when serving.
