Baked Eggplant Recipe ingredients

• Eggplant: it’s important to use fresh eggplants and to cut them as evenly as possible for even cooking.
• Tomatoes: for this recipe, I used cherry tomatoes. However, you can also use grape tomatoes.
• Onions – I recommend slicing a white onion, but you can also use a sweet onion if that’s what you have on hand.
• Basil: to get the incredible flavors from basil, you definitely want to use fresh basil. Dried basil won’t have the same flavors, so I don’t recommend using that as a substitute.
• Herbs & spices – these full flavor steaks call for: Montreal seasoning, paprika, garlic powder, and kosher salt.
• Balsamic: there is nothing better than the incredible flavor of balsamic vinegar with eggplant, tomatoes, and basil. This is definitely an ingredient you don’t want to skip out on!
• Sugar: for this recipe I used  light brown sugar. The light brown sugar adds a touch of sweetness and helps get the eggplants to caramelize in the oven.
• For cooking – olive oil and unsalted butter.

How to make Eggplant in Oven

What temperature to bake eggplant?

1. Preheat the oven. Preheat a griddled cast iron pan in the oven to 425° F.

2. Roast the tomatoes. Place the tomatoes in a 9X12 baking dish and season with salt and pepper. Toss with olive oil and balsamic.

Roast the tomatoes for 20-25 minutes, until they start to burst. When finished, remove from the oven and garnish with fresh basil.

3. Prepare the eggplant. Slice the eggplant into 1 inch thick rounds. Lay the eggplant rounds flat on a cutting board and sprinkle salt over top to draw out some of the moisture. After about 5 minutes, pat the eggplant dry with a paper towel.

How to Season Eggplant

4. Season the eggplant. Brush a thin layer of olive oil over one side of the eggplant and season with Montreal seasoning, paprika, garlic powder, and sugar.

How Long to Bake Eggplant?

5. Bake the eggplant. Carefully remove the griddled pan and arrange the eggplant in a single layer in the pan. If you have sliced eggplant that doesn’t fit in the pan, feel free to put the extras on a lightly greased baking sheet or another griddled pan. Bake the eggplant for 20-25 minutes.

6. Caramelize the onions. Meanwhile, heat a large non-stick skillet on medium heat with olive oil and butter. Add the onions, toss to coat, and cook, stirring occasionally for 15-20 minutes, until the onions have started to caramelize.

6. Serve. Transfer the eggplant to a serving dish and top with the roasted tomatoes and caramelized onions. Garnish with more fresh basil if desired.

Why Do You Salt Eggplant Before Baking?

It’s important to salt your eggplant slices and pat them dry before roasting. Doing so will absorb some of the water, relax the skin, and mute some of the bitterness; giving you a well-cooked eggplant making it the perfect side dish or healthy meal.

How long to salt eggplant?

I recommend salting before roasting as it pulls out some of the moisture before cooking. This technique is often called “sweating the eggplant” and will prevent the eggplant from getting soggy in the seating process.

In this recipe, you only need to salt the eggplant for about 5 minutes to draw out some of the moisture. Since they are baked in the oven, you’ll want to keep some of the moisture in the eggplant so they don’t dry out.

Eggplants are known for their bitter taste and salting them helps to remove some of the bitterness. They can be salted for anywhere from 30-60 minutes.

How to serve Baked Eggplant Steaks

I like to serve the eggplant steaks on a platter with the tomatoes and caramelized onions on top.

For sides, I usually go for something with a carb or a starch like this creamy goat cheese orzo pasta salad or these roasted garlic potatoes. If you’re looking for something with more protein to serve with them, give this air fryer tofu a try!

Oven Baked Eggplant storage

You can store your baked eggplant in an airtight container in the fridge for up to 4 days. To reheat them, just place it on a baking sheet in the oven at 375 F for 8-12 minutes, or until they are heated through.
