This low carb eggplant parmesan casserole is easy to make and requires no breading. It's gluten free and the best keto eggplant recipe you'll eat. Once you try it, you'll want to make this eggplant recipe over and over again!
Eggplant parmesan has always been one of my favorites. I never have made it very often because I didn't like all the work involved. There was breading the eggplant, frying it, making the sauce, putting the casserole together then baking it. Forget all that! I have a new way of doing it which cuts calories and also saves plenty of time. This low carb eggplant parmesan is my lazy way of making a great keto eggplant recipe.
How is this Low Carb Eggplant Parmesan put together?
Don't get me wrong. I love breaded, fried eggplant. Or breaded, baked eggplant. But when you put it in a casserole with sauce and cheese, the breading tends to get a little soggy.
My new way of making eggplant parmesan is to slice the eggplant fairly thin and roast it on parchment paper for 20 minutes in the oven. Do not omit this step because you will have a watery casserole if you don't bake the eggplant first.
The casserole is put together with marinara sauce and cheese. I use my own homemade marinara sauce in this recipe and I always keep some in the freezer. My sauce takes only 25 minutes to make and it is always good to have a batch on hand. The eggplant casserole is baked in the oven for 35 more minutes before it's ready to eat.
Picking the best eggplant
I prefer smaller eggplants because I think they are more flavorful and less bitter. My favorite are graffiti eggplants (below photo) but I also buy Italian eggplants. Both are scaled down versions of the larger purple variety. They both have a finer flesh and skin making it more enjoyable to my palate. However, use whatever eggplant you like because everyone's tastes are different. Eggplant is a vegetable with lots of nutrition and a very tasty way to make dinner.
It is best to slice the eggplant and sprinkle it with salt to release the moisture and bitterness from it before cooking. It's easy to dry with paper towels. Just make sure you set some time to do this. There is a world of difference in the flavor of this baked eggplant parmesan recipe if you do just a little bit of prep work.
What can you serve this Keto Eggplant Recipe with?
If you want to keep your dinner low carb and/or keto friendly, serve this eggplant next to my crispy Air Fryer Chicken Legs or with an Avocado, Tomato and Arugula Salad. It works as a dinner entree or hearty side dish.
If you are not on a keto diet or counting carbs, this eggplant is great served next to pasta or on a hoagie roll.
What About Leftovers?
This recipe reheats nicely in the microwave. It can be kept in the fridge for 3 to 4 days in an airtight container and is also a really good recipe to also make in advance then reheat in the oven.
I don't recommend freezing the leftovers as the texture of the casserole can change and the eggplant can get a bit soggy.
