How to Cook Eggplant in the Oven

How to roast the whole eggplant in the oven?

This way of cooking eggplant is the least popular, so to speak. However, I find that you need to bake the vegetable whole to get a more fragrant eggplant deep, for example. So, let’s see how with several simple steps to follow, you can cook a whole eggplant in the oven:

  • Preheat oven at 200 °С/400 °F.
  • Take two medium-sized eggplants and nicely rinse them under cold running water. Pat them dry with paper towels.
  • Pierce skin of each eggplant in several places and on every side with a toothpick or a fork.
  • Line a baking tray with foil or a baking sheet to prevent it from sticking to the tray while cooking.
  • Keep cooking the vegetables for 35 to 45 minutes (depending on the size of the vegetable).
  • Take baked eggplants out of the oven and let them cool down a bit before using them in other dishes.

For a quick dip, add salt to your taste, pour a teaspoon of olive oil, and sprinkle a teaspoon of dry herbs mix (basil, thyme, and dill are among favorite options). Enjoy!

How to roast eggplant halves in the oven

How to roast eggplant halves in the oven

This roasted eggplant recipe is one of my favorite dishes to have. It is a huge lifesaver because you literally spend 5 minutes making a tasty vegetable dish to serve at your family dinner. Do not get rid of its skin after roasting, as it is high in antioxidants:

  • Preheat oven at 200 °С/400 °F.
  • Rinse eggplants under the running water and pat them with paper towels until dry. Cut the stem and the bottom of the vegetable off. Cut eggplants in half lengthwise and make several diagonal cut lines on the surface of the half.

This step is optional. There are several ways to prevent the eggplant from forming a bitter taste after cooking. The first option is to buy a young vegetable of a small size to roast in the oven. The second option is to sweat eggplants before roasting. However, you need to have spare 30 minutes before even turning on the oven. Cut eggplant in half and sprinkle a pinch of salt over every eggplant half. Leave eggplant to sit for 30 minutes until liquid droplets form on its surface. Get rid of it by gently squeezing the liquid, then rinsing the vegetable and patting it with paper towels.

  • Brush the surface with olive oil. I find that silicon brush is most helpful for this purpose.
  • Spread the baking sheet over the baking tray and place eggplant halves face down.
  • Roast the plant for 35 minutes. In the end, eggplant skin will collapse and gets wrinkled.
  • Season with salt and herbs while the eggplant is still hot. Let it cool down before serving.

When I first came across the recipe, it had rosemary added before placing it into the oven. Unfortunately, it got stuck to the surface of the baking paper, burned, and gave not have the aroma I was expecting from it.
