What is eggplant lasagna?

In my opinion, eggplant lasagna is one of the most decadent dishes you can make for low-carb or keto diets. Like traditional lasagna, it’s a layered dish with sauce and cheese (and sometimes meat), but instead of noodles, you use thinly sliced eggplant.

A typical lasagna has the pasta as a binder to hold all of the sauce and cheese together. Eggplant acts in this same way, while also adding a hearty texture that you just can’t get from zucchini or squash.

Is eggplant low in carbs?

Yes! One cup of cubed eggplant has 4.82 grams of carbs. So, it’s great for keto dieters. Eggplant lasagna is low carb and keto-friendly!

How do you cut eggplant for lasagna?

Do you need to peel the eggplant?

You do not need to peel the eggplant for this low carb eggplant lasagna recipe. The peel of the eggplant is edible and gives a nice texture to the dish. However, if you’re using a very large eggplant, the skin may be a little tough. In that case, you can peel it if you’d like.

Do you really need to salt eggplant?

When it comes to eggplant lasagna, salting is key. Salting the eggplant before cooking it will draw out any excess moisture and help you avoid a watery lasagna. Salt both sides of the eggplant slices and let them sit for anywhere from 10 to 30 minutes. Longer is better, but 10 minutes will suffice if you’re in a pinch.
