About the Onion black outline icon
A plump round bulb narrows to a single pointed tip at the top, and four curved lines run from that tip down to the base, marking the layered papery skin. No leaves or roots are shown, so the shape stays clean and readable. It works for grocery and produce categories, recipe and meal planning apps, restaurant menus, farm market signage and vegetarian or nutrition infographics.
The silhouette is nearly circular with mirrored inner curves, and the tapering skin lines give volume without shading, keeping the icon light on busy layouts. It pairs with garlic, tomato, carrot and potato icons from the same vegetable set. At small sizes, reduce to two inner lines so the bulb does not look striped.
This is the black outline version of the onion icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
