How to choose eggplant
Like any vegetable, you want to make sure you’re getting the best eggplant. Look for beautiful purple eggplant with smooth, shiny skin and doesn’t have too many markings. The eggplant should be firm but not hard and heavy for its size. If you follow these tips, you’ll end up with perfectly ripe eggplant.

Eggplant Substitute
If you don’t care for eggplant, feel free to substitute 4-5 large zucchini. Slice them the same thickness as you would the eggplant, ½-inch thick, but skip the salting process the eggplant requires.
How to make Low Carb Eggplant Lasagna with Spinach & Feta
- Preheat the oven to 425 °F, 220 °C.
- Season the eggplant slices liberally with salt and place them all together in a colander for 20-30 minutes or while the filling is prepared.
Prepare the Filling:
- In a skillet heating over medium heat, add the onion and olive oil with a pinch of salt and cook until soft and golden –about 8 minutes.
- Add the garlic and warm through until fragrant.
- Then, add the spinach in 2-3 batches seasoning each batch with salt and pepper to taste.
- Remove the skillet from the heat and stir in the dill, red pepper flakes, and cream cheese.
- Then, stir in the crumbled feta and taste to adjust seasoning if needed.
- Set aside.
Prepare the Eggplant Slices:
- Rinse the eggplant slices using cold water and dry them using a kitchen towel or paper towels. Be sure to dry them well. Alternatively, skip the rinse and just blot them dry using paper towels.
- You may pan-fry the eggplant (my favorite way) or bake them.
To bake the slices:
- place the eggplant slices in 2-3 baking trays and brush the slices with olive oil.
- Season lightly with salt and roast in a preheated 425°F oven until tender –about 25-30 minutes.
To pan-fry the slices:
- heat a large cast-iron skillet over medium-high heat and add a layer of olive oil to the pan.
- Fry the slices for 2-3 minutes on each side or until they are tender and golden.
- Transfer the slices to a pan that has been lined with paper towels to absorb the excess oil.
Assemble the Lasagna:
- Stir together the marinara sauce with the Harissa sauce –for a smooth sauce, blend it in a food processor or blender until smooth.
- Spread half of the sauce in the bottom of a 9×13-inch baking pan.
- Place a layer of eggplant slices over the sauce.
- Dollop half of the spinach filling over the eggplant and spread it evenly.
- Top with another layer of eggplants and then the remaining filling.
- Add the remaining eggplant slices on top, and then pour the remaining sauce.
- Sprinkle the mozzarella cheese on top.
- Bake on the center rack of the oven for about 45 minutes.
- Allow the lasagna to set for 30 minutes, and then serve.

Make ahead and freeze
After assembling the lasagna, wrap it tightly in plastic wrap and store it in the freezer. It will stay fresh for up to 2 months. Thaw it overnight in the refrigerator before baking.
Serving
After the lasagna has come out of the oven and set, it should be easy to cut your servings. When you pull each slice out, you’ll see the layers have melded together perfectly. Toast some bread because you’ll want to sop up every bit of the spicy marinara sauce. Trust me! Let me know if and what extra veggies you add to your low-carb Greek lasagna. Kali Orexi!

Great ingredients in the recipe. I’m thinking to substitute ricotta for cream cheese and grated parmigiana for the mozzarella. I’m looking to cut down on cholesterol in my cooking.
Thoughts?
Yes, those would be great substitutes!
We love this dish!!!! The first time I made it I followed the directions. Wasn’t happy with the large slices of egg plant, so this time I cubed the eggplant and used one and I added, celery, broccoli, cauliflower, and half the spinach. And in the middle, I put some thick spaghetti noodles after I had cooked them, al dente. So delish!!!!
