This delicious meal is based on a popular recipe, Eggplant Lasagna from the KetoDiet App. Following several requests from my readers, this one is meat-free. As some of you may have guessed, I used eggplant slices and thin egg omelettes to reduce the overall carb count per serving.

Good to know: If you want to get the best out of eggplants, don't peel the skin off. It contains phytochemicals and the eggplant itself is full of antioxidants. Both protect cells from the effect of free-radical damage, therefore eating eggplant regularly can have anti-aging effect. This rich-colored low carb vegetable is also packed with fiber. I love eggplants, they are low in carbs and high in micronutrients, especially potassium. Hope you like my recipe, don't forget to let me know by leaving a comment ;-)

Ingredients (makes 6 servings)

  • 2 medium eggplants / aubergines (750 g / 26.5 oz / 1.6 lb)
  • 1 cup Marinara sauce ( 240 g / 8.5 oz)
  • 300 g fresh spinach (10.6 oz) or g frozen spinach (330 g / 11.6 oz)
  • 1 1/3 cup feta cheese (200 g / 7.1 oz)
  • 1 cup mozzarella cheese, grated (110 g / 4 oz)
  • 1/2 cup parmesan cheese, grated (30 g / 1.1 oz)
  • 6 large eggs, free-range or organic
  • 1/4 cup + 2 tbsp ghee - you can make your own (85 g / 3 oz)
  • 1/2 tsp salt or more to taste (I like pink Himalayan)
  • Optional: fresh herbs such as basil and oregano for garnish

For "regular" Lasagna, instead of the spinach, use 500 g / 1.1 lb ground beef or turkey cooked on a tablespoon of ghee and flavoured with the marinara sauce. When looking for ingredients, try to get them in their most natural form (organic, without unnecessary additives).

Instructions

  1. Preheat the oven to 200 °C/ 400 °F. Slice the eggplant into 1/2 inch (~ 1 cm) slices and place on a baking tray. Grease with 1/4 of melted ghee, season with a pinch of salt and place in the oven. Cook for about 20 minutes. Vegetarian Keto Lasagna
  2. If you're using frozen spinach, let it defrost at room temperature for a couple of hours (or microwave). If you're using fresh spinach, you'll need to blanch it. Bring a pot of water to a boil over high heat. Fill a bowl with ice and water or simply with cold water. Place the spinach leaves into the boiling water and cook for 30-60 seconds. Transfer the leaves immediately into the iced water using tongs or a strainer. One it cools down, remove from the cold water. Drain the excess water by placing the spinach in a strainer and squeezing the excess fluids out. Vegetarian Keto Lasagna
  3. Meanwhile, prepare the Marinara sauce by following this recipe. Vegetarian Keto Lasagna
  4. When the eggplant is done, remove from the oven and set aside. Reduce the temperature to 180 °C/ 360 °F. Prepare the omelettes. Crack one egg at a time in a bowl, season with a pinch of salt and mix well. Vegetarian Keto Lasagna
  5. Pour on in a hot pan greased with ghee (use the remaining 2 tablespoons of ghee for greasing the pan as needed) and swirl around to create a very thin omelette. Cook for just about a minute or two, until the top is firm. Place on a plate and repeat for the remaining eggs. Make a total of 6 omelettes. Start assembling the lasagna by placing a layer of 2 omelettes on the bottom of a banking dish (I used a 9 x 12 inch / 23 x 30 cm baking dish).
    You can create less layers if you like - it's totally up to you. Just make sure you top the lasagna with some mozzarella and parmesan. Vegetarian Keto Lasagna
  6. Spread a third of the Marinara sauce on top of the omelettes. Add a third of the eggplant slices, ... Vegetarian Keto Lasagna
  7. ... a third of the grated mozzarella cheese, half of the spinach... Vegetarian Keto Lasagna
  8. ... and half of the crumbled feta cheese. Top with 2 more omelettes. Vegetarian Keto Lasagna
  9. Repeat layering the lasagna: Spread a third of the Marinara sauce on top, add a third of the eggplant slices and a third of grated mozzarella. Add the remaining spinach and feta cheese. For the last layer, add the remaining omelettes, marinara sauce, eggplant slices and mozzarella cheese. Top with all of the grated parmesan cheese and place in the oven. Bake for 25-30 minutes. When done, the top gets crispy and golden brown. Remove from the oven and set aside to cool down. Cut into 6 pieces / servings. Vegetarian Keto Lasagna Eat immediately or let it cool down and store in the fridge for up to 5 days. The lasagna can be served either warm or cold. Vegetarian Keto Lasagna

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Been on keto for almost three weeks now and my best friend is coming to visit me for one day. She's a vegetarian, I cannot wait to make this dish for her! Will definitely come back and let you know how it goes 😄

Hands down the best lasagna I’ve ever had! I’m down 8 pounds in a little over a week with these meals! 💖 I have a 8 year old and a 6month old and we are a dual military family so this lasagna is perfect as it doesn’t take long to make ! That’s icing on the cake!

Thank you for your lovely feedback, Stacy!

I have an allergy to egg.  What is a substitute for the omlette, please?

I have been thinking of trying these instead but haven't tried it yet 😊 Best Keto & Paleo Tortillas, Taco Shells & Nachos

Hi Kayla, calories per serving are listed as "kcal".

Hi what is a good substitute for the ghee?
Thank you

Reply

Hi Laura, you can use duck fat, lard or even olive oil.

Wow! I just made this and it is delicious. I didn’t use all the ghee making the little omelets but it was still very rich and filling. Thank you so much for this recipe!

This recipe looks amazing! Thank you so much for making this available - I will have to try asap.
One quick note if someone intends to make this dish for someone who is vegetarian - Parmesan is technically NOT Vegetarian friendly.
A lot of cheeses are, but not Parmesan as it is made from rennet - the following link sheds a bit of light on this:- https://www.vegsoc.org/cheese. Its a common misconception.
It's something I always have to clarify when I eat dishes I have not cooked, e.g. salads or even dishes that contain Pesto - as traditional Pesto has Parmesan.
Then again if someone is not vegetarian - jut looking for Keto friendly "non-meat" dishes that is not an issue 😊

Thank you, that is good to know! I suppose in this case other types of hard Italian-style cheese would work too.

We really enjoyed this recipe! Admittedly, we changed a couple of things. We made a smaller recipe for a 9×9 With only 4 eggs and one large eggplant seasoned with Himalaya pink salt and Italian seasoning, and we used vegan mozzarella. This is going in our family favorite recipe book!

Does the calories and ratios change if i use meat instead of spinach??

Reply

Yes it will change if you use meat. You will end up with more protein and also likely more fat per serving.

One of the best meals I ever cooked and ate in my life

Reply

Thank you! I'm glad you enjoyed!

I can't wait to make this. I don't have feta, but I have some delicious garlic herb soft goat cheese that will be lovely. I have truly been enjoying all the dishes I've made this week. This makes my fourth dish in a row from your blog and the app. 💗

Thank you for your kind words, Amanda!

Mmmmm! What a treat! This lasagna is so dang delicious. Thank you for the recipe! It lives up to the hype.

I was skeptical of this recipe. I can be a bit picky about veggie lasagnes, and I wasn't sure if I'd like the eggs. Omg. So good. This was seriously delicious. I think this will be a regular in the rotation!!!
Does it freeze well? I see that you said it can refrigerated for up to 5 days, so I'd like to keep the extra portions for later. Thanks!

Reply

Thank you for your kind words Anna! Yes, it can be frozen for up to 6 months 😊

Reply

So I can cook fully wrap in foil and freeze, then do I rebake it to eat or just defrost and heat in microwave. I was thinking about putting in portion containers and feezing so I pull out just what I need so it last longer!

Reply

I would let it defrost in the fridge overnight and then reheat in the oven so the cheese can melt and crisp up. But even reheating in a microwave oven will work 😊

My wife and I were blown away with how good this was. We've been experimenting with low carb veggie dishes, and we've found several we like, but this is far and away our favorite so far. Thanks for the recipe.

Thank you Ramon, I'm glad you both enjoyed it!

Thank you so much! This is the best lasagna I´ve ever had!!!

This is sooo good! It was a hit even with non vegan non ketonites.

Reply

Thank you Miles! 😊

Reply

Can you suggest a replacement for eggs.

Reply

You could use more eggplant slices or zucchini slices but it will result in more carbs per serving.

Reply

Could I use ricotta cheese instead of feta?

Reply

Yes, that will work too 😊

Can you recommend a substitution for eggplant? I'm allergic, unfortunately but I'd really like to try this recipe. Looks great!

Hi Alana, I guess you can try zucchini slices instead? 😊

OMG thank you so much for this! It took some time to put this together, but it's absolutely worth the effort. This was delicious reheated at lunch today, and I honestly could not tell the difference between your "egg" lasagne sheets and the traditional ones. This made my day 😊
