This is a very easy tutorial but it’s still recommended that you start in pencil and make light lines that are easy to erase in case you make a mistake.

Step 1 – Draw the Shape of the Onion Bulb

Before you start drawing the onion bulb be sure to leave enough room at the top of the page for the leaves.

Start by drawing each each side of the onion bulb. They do not have to be perfectly symmetrical but try to get them as similar to one another as you can.

Step 2 – Add the Top & Bottom of the Bulb

Now close up the “gaps” on the top and bottom of the onion bulb. The top part where the onion transitions into the leaves usually tends to be fairly uneven. Draw that area as a set of random sized pointy clumps.

Close up the bottom gap where the the roots grow form with just a wobbly line.

Step 3 – Draw the Leaves

Growing from the top part of the bulb draw the leaves. Start by drawing the ones in front first and then draw the ones sticking out from behind them.

To make the onion look like try and make the leaves fan out fairly evenly in different directions.

Step 4 – Draw the Roots

Somewhat similar to the leaves draw the roots. Make these slightly more wobbly then the leaves where a few of the roots have wave like shapes bending in one direction and then another.

Again draw the roots in front first and then add the ones that are partially hidden behind them.

Step 5 – Finish the Line Drawing

To finish the line drawing add a few lines that curve along the onion bulb and give it that characteristic onion look. Afterwards go over it with either darker pencil lines, black pen or marker.

Step 6 – Color the Onion

To color the onion you can make the bulb a golden brown and the leaves a yellow/green. Leave one or two white spots on the bulb for the highlights (where the light is reflecting from it’s shiny surface).

If coloring with paints you can mix some orange, brown, and yellow to get the bulb color. If coloring with pencils you can do the same by simply going over your drawing with several layers of color. Also be sure not to press too hard on the pencils when coloring or the initial layer may become to dark to color mix with the rest.

Conclusion

An onion like the one in t his example is fairly quick an easy to draw. If you find it difficult to get both halves to be fairly symmetrical you can draw a straight line between them to see if they are relatively even and erase it after.
