Commonly asked questions

Is it okay to eat eggplant that is brown inside?

If you slice and eggplant and it is brown on the inside then we suggest you throw it out. Good eggplant shoulnt be brown and it should be more on the white side. Darker colored seeds are fine. Sometimes eggplants that are frozen and thawed will have a slight yellowish tone to it which is fine.

Do you soak eggplant before cooking?

For this recipe it is not necessary to soak the eggplant. Once the eggplant is sliced, you may set then on a flat surface, sprinkle a bit of salt over them, and allow moisture to sweat out of the eggplant. Same goes for the zucchini. Dab the excess moisture with a paper towl. This step is not necessary but optional.

Do you leave the skin on eggplant when you bake it?

The skin of an eggplant is edible. Especially if the eggplants are small or medium in size. Once cooked they will be soft enough to eat. If the eggplant is quite large, chances are the skin will be tough. We did not peel the egglants or rhe zucchini for this baked egglant and zucchini dish.

    Great recipe! Switched Italian seasoning for Greek seasoning and the Parm for crumbled feta on top was to die for!

    I made this for family dinner and it was a crowd favorite. So easy to make and delicious.

    I used red peppers instead of tomatoes and it was delicious.

    So tasty! I altered it a bit as I only had grape tomatoes and the eggplant and squash were very different widths. I’m by n means a cook and this was so easy and good. Thank you for sharing it.
