The Two Main Types of Eggplant
There are so many different varieties of eggplant out there, but there are two main kinds you’ll find in most grocery stores.
- American Eggplant (Recommended for this Recipe): American eggplant is the variety you are most likely familiar with. It’s most commonly used in eggplant parmesan and features a dark purple exterior and a soft, inner flesh.
- Chinese Eggplant (A Good Runner-Up): Chinese eggplant is the second most common eggplant found in conventional grocery stores. It’s long and skinny and features a dark purple exterior and firm inner flesh. You’ll find it served in a wide variety of Asian-style stir fry dishes.
Preparing this Easy Eggplant Sandwich Recipe
For as fancy as this recipe looks, it’s actually so simple to put together and only requires 8 ingredients. Here’s how to do it:
- Prepare the Eggplant: First, slice the eggplant into 1-inch thick rings and assemble them in a single layer on a rimmed baking sheet. Brush them with olive oil and sprinkle on some salt.
- Roast the Eggplant: Next, bake the eggplant at 415°F for about 15 minutes or until golden brown. Set the eggplant aside to cool at room temperature.
- Make the Garlicky Mayo: Press the garlic into the mayo and stir to combine.
- Assemble the Eggplant Sandwiches: Spread a thin layer of the mayo on top of each eggplant slice and top with tomato and mozzarella. Next, top each sandwich with another eggplant slice and a garnish of fresh basil leaves or a sprig of dill. Enjoy!
Hot Tip: Up-level the sandwiches with a drizzle of balsamic vinegar or a couple of cracks of black pepper.
Handy Tips & Tricks to Help You Along the Way
A couple simple tips and tricks will help you knock this eggplant sandwich recipe out of the park.
- Pat the eggplant dry of any excess moisture. After cleaning the eggplant under cool water, use a paper towel to pat it dry. This will help it get crispy in the oven!
- Grill eggplant slices for a smokier flavor profile. If you’d like, grill the eggplant instead of roasting it. You can also cook them on the stovetop in a grill pan.
- Use fresh mozzarella. You’ll want to opt for soft, fresh mozzarella over harder varieties. If the kind you’re using comes packed in water, make sure to pat it dry so it doesn’t make the sandwiches soggy.

Tops Tips for Make-Ahead & Storage

That said, you can always prepare the garlicky mayo a couple of days in advance and store it in an airtight container to let it really develop its flavors. When it comes to leftovers, you’ll want to play it by ear since these are best eaten fresh.
