Oven-baked eggplant slices are easy to reheat and can be served warmed or at room temperature. I love it with my dairy-free basil pesto drizzled on top or dipping into a San Marzano tomato sauce.
📖Why My Recipe Works
- Brine Method- While many cooking websites say that salting, or brining the eggplant, isn't necessary because modern eggplants are less bitter I just don't agree. I find the salt improves both the flavor and texture.
- Quick and Easy- There are so many delicious ways to make eggplant, but cutting them into slices is perfect for a variety of applications and is much faster than cubes or whole eggplant.
🧾Ingredient Notes
The base recipe uses just oil (any type but olive oil is recommended) and salt and pepper. Additional seasoning options include fresh herbs like thyme or rosemary, Italian seasoning, cajun seasoning, or harissa seasoning for a spicy kick.
How to Select Eggplant
Look for eggplant with firm, unblemished skin. The eggplant should feel heavy for its size and be free of soft spots. You can check by giving it a gentle squeeze it should feel firm, not spongy or too hard.
Most of us are used to Italian eggplant, which is found in most supermarkets. However, smaller eggplants like the Thai and Japanese eggplant varieties are becoming more readily available, especially from your local farmer's markets.
Any of these varieties work well when roasted - just make sure you're picking a good eggplant from the start and that you slice it appropriately for its shape and size, long ways vs crossway.
⏲️How to Roast Eggplant Slices

Slice
Cut into rounds, between ⅓ - ½ inch thick. For longer thinner eggplants, slice lengthwise. Smaller eggplants may just need to be sliced in half.

Salt Brine
. Allow the eggplant to sit for 10-30 minutes while the salt pulls out excess moisture. Gently rinse the eggplant and use a towel to lightly push out the excess water.

Bake
Spread out the eggplant in a single layer on the baking sheet and lightly brush oil on both sides. Sprinkle with black pepper. Do not add additional salt, the initial salting has seeped in and you can always salt to taste later.
Roast for 15 to 20 minutes. Flip the eggplant slices halfway through for even caramelization. The eggplant is done when both sides are golden brown.
🥗How to Serve Baked Eggplant Slices
I used to avoid eggplant. I just wasn't really sure how to use it outside eggplant parmesan. But now it is a staple in my kitchen.
Enjoy with polenta cakes and fresh romesco sauce or in a roasted veggie sandwich as a main course.
As part of a veggie stack with roasted zucchini, roasted portobello mushrooms, and roasted red onions. Or serve as a side with a garlic butter sauce and sprinkled with micro greens and parmesan cheese

👩🏻🍳 Expert Tips
- Experiment with different varieties of eggplant. Each type will add its own unique flavor to this delicious recipe.
- I prefer to line a baking sheet with parchment paper to prevent sticking. Alternatively, you can oil the baking sheet but I find parchment works better.
- Don't cut the slices too thin, they will fall apart when baked.
💬 Why is my eggplant mushy?
Three things cause mushy eggplant. First, using too much oil. Second, not cooking at high enough heat, or not allowing the oven to fully preheat. Not absorbing excess moisture with a towel before cooking.

Notes
- Parchment paper is optional but will prevent sticking.
- Roasted eggplant slices are best served immediately. However, leftovers can be stored in the fridge in an airtight container for up to 3 days. It will become watery so drain before reheating in the oven at 300 F degrees.
- I do not recommend freezing sliced eggplant.

Eggplant tastes great when roasted, or deep-fried. Roasting is easier, so most of the time, they end up roasted in my house. 🙂

Have you ever frozen this after preparation?

Is rinsing with water necessary after salting & sitting for 15 minutes?

I typically don't rinse unless I went heavy on the salt.
