Oven-baked eggplant slices are easy to reheat and can be served warmed or at room temperature. We love it with our dairy-free basil pesto drizzled on top or dipping into this amazing San Marzano tomato sauce.
We have been on a roasting streak in the Peel house lately. Maybe it is colder weather. You can check out our most recent slow roasted tomatoes and our roasted garlic to see what I am talking about. Serious goodness! And now we have moved on to eggplant.

📖 Why This Recipe Works
Not sure how to make eggplant quickly? Does your eggplant ever turn out rubbery? What about an odd bitter flavor? Then this eggplant recipe is for you!
We struggled to make baked eggplant for years. Then I realized what I was doing wrong. I wasn't salting to draw out moisture and then when I finally learned that trick I followed conventional wisdom and did it for a full hour. Way too long!
I finally got the hang of it. 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.
Plus when selecting an eggplant you never exactly how bitter it might be. Better safe than sorry!
A few tips and tricks when it comes to properly baking sliced eggplant. A little pre-salt goes a long way, the thickness of the slices really matters and temperature is key. Let's get to it!
How to Select Eggplant
Most of us are used to Italian eggplant that 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.
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.
⏲️How to Make Eggplant Slices in the Oven
If you aren't an eggplant lover, I promise this cooking method will change your mind. It is my favorite roasted eggplant recipe and a delicious way to cook eggplant quickly.
Step 1-Cutting the Eggplant Rounds
Trim the ends and cut into rounds, between ⅓ – ½ inch thick. For longer thinner eggplants, slice lengthwise. Smaller eggplants may just need to be sliced in half.
Step 2-Brine the Eggplant
Lay eggplant on a wire rack, and generously sprinkle each side with salt. 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.
Step 3- Season and Bake
Preheat the oven to 400 F degrees. I prefer to line a baking sheet with parchment paper to prevent sticking. Alternately you can oil the baking sheet but I find parchment works better.
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.
Additional seasoning options include Italian seasoning, cajun seasoning, or just some simple garlic powder.
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. Top with fresh herbs and serve.
🥗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 our lives. Here are some of the ways we like to serve this recipe:
- Topped with San Marzano marinara sauce, mozzarella cheese, and fresh basil or parsley for a a simple side dish
- Enjoy with polenta cakes and fresh romesco sauce.
- As part of a chicken bowl, sprinkle with zaatar and add fresh tomatoes, olives, and parsley.
- As part of a veggie stack with vegan basil pesto, our roasted zucchini, portabella mushrooms, and red onions.
- Rolled with our roasted garlic cashew cream cheese stuffed inside and a fresh tomato sauce drizzled on top, the perfect vegan main course
- Serve as a side with a garlic butter sauce and sprinkled with microgreens and parmesan cheese
- Serve with pork tenderloin and carrot-ginger dressing
- In a roasted veggie sandwich

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