The thought of how to cut an eggplant can seem intimidating at first, but with a sharp knife and cutting board, you will have your favorite sliced and cubes eggplant ready for roasting in your favorite recipes.

Aubergines are rich in fiber and natural minerals that provide nutrients and vitamins to the body. We are huge fans of eggplant and like it in more ways than frying or roasting. Here are some ideas:

How to Choose Eggplant

Be sure to pick out an eggplant from the garden or store that is slightly firm but still soft to the touch. The color of the eggplant should be a deep hue of purple.

A ripe eggplant is much easier to cut into criss-cross strips, cubes, and rounds than a premature eggplant so are sure it is soft enough to cut through. If the eggplant is too soft, then avoid it as it will be too messy.

How to Cut an Eggplant

With three easy step-by-step methods of cutting and slicing an eggplant, you will learn the easiest way to roast your aubergine. We are going to cover everything you need to know about how to cut eggplant in three different ways.

Cutting the Eggplant into Circular Rounds

First, select a soft yet firm eggplant. Wash the eggplant with cool filtered water then dry it off.

Place the eggplant on a cutting board, then with a sharp knife, carefully slice the stem off the top of the eggplant. This will expose the white inside of the eggplant.

Next, with the eggplant lying on its side, carefully slice a half-inch round circle off of the eggplant as demonstrated below. Continue to slice the even rounds from the eggplant until you have cut through all of the eggplants.

Next, we will talk the eggplant into cubes. Eggplant cubes are great for frying or roasting the eggplant when you want to enjoy it by itself with a little sea salt and pepper.

How to cube an eggplant into Chunks

Start by slicing the stem off the top of the eggplant in addition to the bottom–be sure to slice about a half-inch off the bottom of the eggplant making the bottom flat.

Next, while the eggplant is standing up, carefully slice the eggplant into four long pieces. After that, place the eggplant down on the cutting board flat side down, and cut more slices crisscross against the lengthwise slices.

Continue to cut against the lengthwise slices until you have diced the eggplant into several diced pieces.

How to Slice an Eggplant into Lengthwise Slices

First, start by slicing the top and bottom off the eggplant creating a flat bottom. Next, slice the eggplant straight down the middle with a sharp knife.

Next, cut the eggplant into four pieces from the two halves. After cutting the eggplant into four pieces, slice the eggplant into four more even lengthwise pieces until you have cut all of the eggplant slices.

The results should be even slices that can be used for casseroles, lasagnas, parmesan bakes, and so much more.
