Aubergine Gratin or Eggplant Gratin

I just love the name "Aubergine." It sounds fancier than "Eggplant." This eggplant gratin is highly nutritious, delicious, and super easy to make for the summer and fall months. The tender vegetable layered with sauce, cheese, and herbs is incredibly satisfying for those days you may want something hearty yet healthy. The dish can also be made vegan if the cheese is substituted for vegan versions.

Aubergines belong to the Solanaceae family and are known for their distinctive egg-like shape and vibrant colors, which can range from deep purple to white, green, or even variegated shades.

The flavor of aubergines is often described as mild and slightly earthy, with a somewhat creamy texture when cooked. They have a sponge-like quality that allows them to absorb flavors and sauces during cooking. Since marinara sauce is used to create this dish, the eggplant graciously soaks in the flavor of the sauce and herbs.

Homegrown Goodness

This season, I was able to obtain homegrown aurbergines (eggplants) from another gardening friend. Her eggplants were juicier with thicker skins, which added a unique texture to the gratin. However, thicker skins are not for everyone, so feel free to use whatever variety of eggplant is best suited for your taste.

According to The Spruce Eats, the most delicate and least bitter eggplant is the Rosa Bianca Eggplant. They are teardrop or pumpkin shaped with beautiful violet and white streaks. They also have fewer seeds if you are not a fan of them. Unfortunately, these are not readily available, so you may have to grow them yourself or check with your local farmer’s market. For this recipe, I used the standard, readily available Globe Eggplant.

When selecting aubergines for cooking, look for ones that are firm, glossy, and without blemishes or wrinkles. Prior to cooking, aubergines are often salted and allowed to sit to remove excess moisture and reduce bitterness.

I seasoned this dish with my homemade Fresh Italian Seasoning. Fresh Italian seasoning is strong in flavor with a wonderful herbaceous touch. I used hot and spicy oregano, barbeque rosemary, curly parsley, and lemon balm thyme to create this fresh seasoning blend. You can use any fresh variety of herbs you may have on hand such as Greek oregano, Tuscan blue rosemary, Italian parsley, or English Thyme.

If time permits, make some homemade Marinara Sauce in advance to deepen the flavor of the gratin.
