What Makes This Recipe So Good
Eggplant – Mild, yet still rich, with a creamy texture, eggplant is the perfect veggie substitute for noodles. Just make sure you remove as much moisture as possible! (I’ll tell you how down below!)
Marinara – An easy homemade marinara sauce gives the lasagna plenty of traditional Italian flavor.
Ricotta filling – The cheesy, creamy ricotta filling is loaded with spinach, mozzarella and parmesan, earthy basil, bright lemon zest, and garlic that takes your lasagna to the next level.
How To Make It
The full recipe & ingredients list are below, but here you’ll find a quick overview for making this recipe perfectly, along with useful tips and info!
Cut off the ends of the eggplant, then cut slices lengthwise. They should be about 1/8 of an inch thick.
Sprinkle the eggplant slices very liberally with sea salt on both sides, then let them sit for about 10 minutes. Pat the slices very, very dry with some paper towels. (The salt draws the moisture out of the eggplant slices, making the lasagna less watery, so you’ll want to remove as much moisture as you can!)
Stir together the marinara ingredients in a bowl.
In a separate bowl, beat the egg. Add the rest of the ricotta filling ingredients and mix well to combine.
In a baking dish, add enough sauce to cover the bottom and spread it evenly. Add a layer of eggplant slices on top, covering the bottom of the dish completely. It’s okay if the slices overlap a little! Spread a layer of the ricotta filling over the eggplant slices and then repeat everything.
Top off your lasagna with a layer of sauce, then sprinkle the rest of the mozzarella and parmesan on top.
Bake the lasagna until the cheese is fully melted, then turn on the broiler and let the cheese gets brown and bubbly.
Remove the lasagna from the oven and let it sit for a few minutes before sprinkling the basil on top.
- If there is any excess moisture from the eggplant after baking, remove one square of lasagna and place a balled up paper towel in the empty square. This will help soak up any of that excess water.
- When picking your eggplant, look for a medium sized one. It’ll be large enough to cut into enough pieces for your lasagna, but also will not have the bitterness than large eggplants tend to have.

For the Marinara
For the Ricotta Filling
- 2 tablespoons basil leaves shredded
- 1 large egg
- 1 15-ounce container ricotta cheese
- 2 cloves garlic minced
- ½ teaspoon lemon zest
- 10 ounces frozen spinach thawed, liquid squeezed out
- 2 cups shredded mozzarella cheese divided
- 1 cup grated parmesan cheese divided
- Preheat the oven to 375° F. Cut off the ends of the eggplant, then cut lengthwise to make slices about ¼" (7mm) thick. Sprinkle the eggplant slices VERY liberally with sea salt on both sides. Let sit for 10 minutes to draw out the moisture, then pat VERY dry with paper towels to remove any excess water.
- Make the marinara: Stir together the crushed tomatoes with the garlic powder, Italian seasoning, red pepper flakes, and a pinch of salt.
- Make the ricotta filling: In a medium bowl, beat the egg. Add the ricotta, 1 ½ cups of mozzarella, ½ cup of parmesan, lemon zest, ½ teaspoon salt, and 1 tablespoon basil. Mix well to combine.
- Assemble the lasagna: In a 9×13-inch (23×33-cm) baking dish, add enough sauce to cover the bottom of the dish. Spread in an even layer. Add a layer of eggplant slices on top. It's okay if the slices overlap slightly.
- Add a layer of the ricotta filling and spread in a thin, even layer.
- Repeat with the remaining ingredients in the same order, finishing with a layer of sauce. Sprinkle the remaining mozzarella and parmesan on top. Bake for 45 minutes, until cheese is fully melted. Then turn on the broiler for 5 minutes, or until the cheese on top is browned and bubbly. Remove the lasagna from the oven. Let it rest for 15-20 minutes to allow lasagna to set. Garnish with fresh basil and cut into 12 even squares.
- Excess moisture after baking: Remove one square of lasagna and place a balled up paper towel in the empty square. This will help soak up any of that excess water.
- Picking the perfect eggplant: Look for medium sized one. It will be large enough for this recipe but will not be as bitter as large eggplants.
