Eggplant lasagna in baking dish

I love classic lasagna as much as the next person, but I'm all for a fun twist on old favorites–from lasagna soup to lasagna roll ups to this eggplant lasagna!

The gist: this vegetarian eggplant lasagna carries all the comforting Italian flavors we love--complete with layers of a flavor-packed cheese mixture with spinach and fresh herbs + red pasta sauce (you can use store-bought marinara for a shortcut, or try my homemade spaghetti sauce). But in place of the noodles, we have velvety tender roasted eggplant slices!

Admittedly, I've never met an eggplant casserole I didn't enjoy (moussaka anyone?) Actually, I'm a big fan of eggplant recipes in general, which you'll see by all the different ways I use it in my cooking!

But there is something extra tasty and comforting about this recipe! And I'm telling you, this low carb lasagna with roasted eggplant is as hearty and delicious as any good lasagna recipe should be.

If you watch my video below, you'll see how easy it is to make. And I've included some tips and make-ahead ideas, if you need them!

How do you slice eggplant for lasagna?

In this recipe, eggplant is low carb option that replaces the pasta sheets in this recipe. With that in mind, the best way to cut it is in long slices or planks that are ½-inch thick.

You'll see in my video below that I also trimmed the eggplant and did not use the very short sides.

And you do not have to peel the eggplant before making this eggplant lasagna recipe.

Prepare the eggplant

Before you assemble the lasagna casserole, you have two easy steps to prepare the eggplant:

  • Salt the eggplant (optional). The big debate, to salt or not to salt the eggplant before cooking. Most eggplant is really not that bitter, but I still like to salt my eggplant slices and let them "sweat" for a few minutes while I prepare the rest of the ingredients. This is a great way to infuse the eggplant with flavor, and the salt does break the spongy texture a bit. Just be sure to wipe off all the excess moisture and salt well before cooking.
  • Roast the eggplant. You do need to cook the eggplant planks a bit so that they become pliable enough to use in place of lasagna noodles.
    But unlike eggplant parmesan where we the eggplant is breaded and fried, for this low carb eggplant lasagna, we simply need to roast it. Roasting breaks eggplant's spongy texture and concentrates its flavor, turning it into something fragrant, delicate and almost addictive (this is why I make my roasted eggplant recipe often around here).

How to make eggplant lasagna: step-by-step

(print-friendly recipe with ingredient list and video below)

  • Slice and salt the eggplant. You want slices (or planks) that are about ½-inch thick. Salt the eggplant and leave it alone for 20 minutes or so (This is totally optional as I explained earlier). Wipe the eggplant well to dry and remove excess salt (you can also rinse it if you want, but you'll have to make sure and dry it well).
  • Roast the eggplant. Grab 1 or 2 large sheet pans and brush with a bit of extra virgin olive oil. Arrange the eggplant slices in one single layer. Roast in the oven at 400 degrees F for about 20 minutes or until the eggplant is soft and pliable

  • Make the filling. While the eggplant is roasting, put together the ricotta filling. In a mixing bowl, combine 1 beaten egg with the ricotta (I used part-skim), 1 cup shredded mozzarella, ¼ Parmesan, garlic, oregano, 10 ounces thawed spinach (make sure you get rid of all excess water), chopped parsley and basil. Season with a bit of kosher salt and black pepper. Mix really well to combine Add a small pinch of kosher salt and black pepper to your liking. Mix well to combine.

  • Assemble the eggplant lasagna. Grab a 9 x 13-inch baking dish. Pour a little bit of the pasta red sauce on the bottom (about ½ cup) and spread it. Arrange a few eggplant slices on the bottom of the baking dish (whatever will fit to cover the bottom of the dish; 4 to 6 slices).

    Spread a layer of the ricotta filling (about ½ of it), then spread a thin layer of the pasta sauce. Repeat the process in the same pattern until you're finished.

    Top with a final layer of sauce and follow with the remaining ½ cup mozzarella cheese and ¼ cup of Parmesan.

  • Bake! Cover the dish tightly with foil. Bake in the oven at 375 degrees F for 15 to 20 minutes, then carefully uncover and return to the oven to bake for another 10 to 20 minutes until the top layer of cheese is nice and melted and some edges of the vegetarian eggplant lasagna turn a nice golden brown.
  • Let rest 10 minutes before cutting it up! Allow the cheese and everything some time to settle, if you try to cut it while it's hot, it will be messy. Garnish with a bit of fresh parsley or basil, if you like.

Prepare Ahead, Leftovers and Storage:

  • To prepare ahead: You can roast the eggplant and prepare the ricotta cheese filling 1 day in advance. Keep them refrigerated in separate containers. Assemble just before baking. When ready to bake, let the lasagna stand at room temperature while you preheat the oven.
  • Leftovers & Storage: Refrigerate leftovers for up to 4 days. Rewarm, covered, in a medium heated oven.
  • To reheat: Warm, covered in a 350 degrees heated-oven

Can you freeze it?

I'm not a fan of freezing this eggplant lasagna as eggplant can become too watery and mushy when frozen. And in the absence of sturdy noodles to hold the casserole together, it will be more challenging.

What do you serve with vegetarian eggplant lasagna?

To me, this dish can stand alone as dinner just add your favorite salad and call it good!

Italian Salad would be an easy choice, but if you're looking for another light and fresh salad, try my lazy tomato and cucumber salad or this lemony arugula salad. For something more hearty, try my fresh Mediterranean bean salad.

Eggplant lasagna in baking dish
All the tasty flavors and the comfort of lasagna without the noodles! Roasted eggplant slices, layered with a delicious cheese mixture with spinach and fresh herb, and of course a little red pasta sauce. This hearty vegetarian eggplant lasagna can stand alone as dinner (2 pieces per person) along with your favorite salad!
Prep – 30 minutes
Cook – 40 minutes
Cuisine:
Italian
Serves – 12 pieces
Course:
Dinner

Ingredients
  

  • 2 to 3 eggplants (about 1 ½ pounds), sliced lengthwise into ½-inch thick slices (about 12 slices)
  • Extra virgin olive oil
  • Kosher salt
  • 1 large egg
  • 1 15-oz tub part-skim ricotta cheese
  • 1 ½ cup park-skim mozzarella cheese divided
  • ½ cup grated Parmesan cheese divided
  • 3 garlic cloves minced
  • 1 teaspoon dried oregano
  • 10 oz frozen spinach, thawed and fully dried (wring out all the water)
  • 1 cup packed chopped fresh parsley
  • ½ cup packed chopped fresh basil ⅔ ounce
  • Black pepper to your liking
  • 2 cups prepared pasta sauce of choice (Homemade or store-bought)

Instructions
 

  • Season the eggplant slices on both sides with kosher salt and set aside for 20 to 30 minutes (if you don't have the time, this step can be optional).
  • Meanwhile, preheat the oven to 400 degrees F and position a rack in the middle.
  • Wipe the eggplant slices very well with a paper towel (you want to dry it well and remove any excess salt), then arrange on lightly oiled baking sheet (or two if needed). Brush the top of the eggplant with extra virgin olive oil. Roast in the heated oven until the eggplant softens and becomes pliable (about 15 to 20 minutes or so).
  • While the eggplant is roasting, prepare the ricotta filling. In a mixing bowl, beat the egg. Add the ricotta, 1 cup mozzarella, ¼ Parmesan, garlic, oregano, spinach and chopped herbs. Add a small pinch of kosher salt and black pepper to your liking. Mix well to combine.
  • Remove the eggplant from the oven. Lower the heat to 375 degrees F.
  • Prepare a 9 x 13-inch baking dish. Pour a bit of the pasta sauce (about ½ cup or so) and spread it out into one layer. Lay a few eggplant slices (anywhere from 4 to 6 and it’s fine if they overlap a bit). Spread ½ of the ricotta filling, then spread a thin layer of the sauce. Repeat the process in the same pattern. Spread the final layer of sauce and follow with the remaining ½ cup mozzarella cheese and ¼ cup of Parmesan.
  • Cover the dish tightly with foil. Bake in the heated oven for 15 to 20 minutes, then carefully uncover and return to the oven. Bake for another 10 to 20 minutes or until the cheese has melted and the edges of the lasagna turn a nice golden brown.
  • Let the lasagna rest for 10 minutes before cutting and serving.

Notes

  • Salting eggplant is optional but it does help the flavor and texture of it. Be sure to wipe the eggplant slices very well to remove any excess salt (you can also rinse it, but you'll need to make sure to dry the eggplant super well). 
  • Prepare Ahead Tips: You can roast the eggplant and prepare the ricotta cheese filling 1 day in advance. Keep them refrigerated in separate containers. Assemble before baking. When ready to bake, let the lasagna stand at room temperature while you preheat the oven.
  • Leftovers & Storage: Refrigerate leftovers for up to 4 days. Rewarm, covered, in a medium heated oven.
  • To reheat: Warm, covered in a 350 degrees heated-oven
  • Can this be Frozen? It is best not to freeze eggplant lasagna as eggplant can become too watery and mushy when frozen.

    1. I make eggplant lasagne using all the required ingredients mentioned, but I also put ground beef in it. That way I get my protein also. It's yummy n my family enjoyed it.

  1. I prefer the parmesan garlic sauce over the tomato sauce using fresh vegetables like celery carrots bell peppers basil and spinach mushrooms adding a touch of feta cheese to individual plates always a good dish .

    this has become one of my favorite dishes. Can I do more than 2 layers, or will it not set as well?
    Thanks

    I made this for my iftar dinner for vegetarian night. It was faaaabulous! Bursting with flavors and the eggplant was cooked to perfection. I don’t know if I’m ever going to go back to regular lasagna after this recipe!

    1. Sure! I have never tried it myself, but I just did a little quick research, and it looks like 10 oz. frozen spinach is equivalent to approximately 1 lb. of fresh spinach, so I would start there. Also, with fresh spinach, I would blanch it first, and then be sure to squeeze all the water out.

    Hi Suzy! I think I've tried your recipes at least 7-8 days in a row now. 🙂 So far I have made Baked White Fish Mediterranean Style, Greek Salmon Salad, Grilled Shrimp with roasted garlic-cilantro sauce, Greek Pastistio, Chicken Cacciatore, Egyptian Hawawshi, Chicken Schnitzel, Easy-Greek Style Eggplant and today I made the Eggplant Lasagna. Not once have I or my teenagers been disappointed. Not only does everything taste delicious, I have lost some weight as well. Can't wait to eat my way through your recipes (cooking is kind of meditative for me). Keep 'em coming! 🙂

    1. Wow! You are on a roll with the recipes! I'm so glad you and your family are enjoying them. Can't wait to hear what yes you try!!

    Since this recipe was added in October 2020, we have made this a number of times as it is delicious the time it comes out of the oven as well as it is perfect for left overs (makes for a great day #2 lunch!). It also helps us increase the amount of veggies that we are consuming. Love the tip about making both the cheese filling & roasting the eggplant the day before. Tried that tip this past week & it made it easier for a busy schedule! If making just for two people, can definitely cut the recipe in half & it turns out just as good.

    Wonderful! My husband doesn't think he likes eggplant but I have now made a few things with eggplant including this dish and he loved it. Great way to get eggplant in the dish and make it all taste amazing.

  7. 5 stars
    This was absolutely delicious! I followed the recipe exactly as it was written and opted for the homemade sauce. Two of my children were afraid to try it because they thought eggplant would be yucky. They ended up going back for seconds. My husband didn't even realize there was no pasta in the recipe...he said it's hard to get lasagna just right, and this one hit the spot. Thank you so much.

    We look forward to trying all of your vegetarian recipes! Looking forward to a cookbook.

  8. What a gorgeous dish! Thank you so much for sharing it. It worked out perfectly. A few comments: the skin is super nutritious so I didn't discard any of it. Also, would it ever be possible to include metric measurements? Thank you!!

    Hello sister Suzy, I am honored to present to our FB Group the "Women In God's Heart ❤" your recipe. Thank you for sharing these recipes to all the moms and friends. If you don't mind, please allow me to share your Great Recipes to our group on a weekly basis. Thank you and more power! God bless ❤🙏

  10. Does the 1.5 lb indicated for the eggplants mean 1.5 lb each or l.5 lb total between all 2-3? Thanks! Really looking to trying out this recipe.

  11. The 20 minutes of prep time is SUPER misleading. There is no way you can slice, salt, blot, and roast the eggplant inside of 20 minutes or even close, not to mention gathering, measuring ingredients for the filling, thawing and squeezing spinach, grating various cheeses, finely chopping large quantities of herbs etc. Please tell me how all the prep steps can be completed in 20 minutes. Very frustrating. We’ll be eating our special dinner after 8 pm due to the misleading time estimate.

    1. Hi Gayle, thank you for sharing. If you'll notice, the eggplant roasting time is a separate calculation outside of prep (it is added in the cooking time. 15 minutes to roast the eggplant, then another 25 minutes or so for cooking the casserole for a total of 40 minutes cooking time). One thing that usually helps with prep is to get the eggplant salted first, then while it is sitting, work on the rest of the ingredients. This is good feedback that we appreciate as we all work in the kitchen differently and things like this will vary. The prep time was adjusted per your feedback.
