RELATED ONOMATOPOEIA:

  • サクサク: lighter, crisper crunch (thin cookies, pastry); also means "smoothly" for work
  • ザクザク: heavier, coarser crunch (thick cuts, gravel, snow)

The voiced ザ vs unvoiced サ reflects the weight of the sound — ザクザク implies something rougher and heavier than サクサク.

USAGE:
Sense 1 is commonly used for chopping vegetables into rough chunks, walking on gravel or snow, and describing the texture of certain foods.

Sense 2 often appears in advertising and casual speech to emphasize abundance, especially with money or rewards.
