Quick Answer

Mushy grilled vegetables happen from overcooking, slicing too thin, or using vegetables that don't hold up on the grill. Slice thick: 1.5-2cm for most vegetables.

Why This Happens

Mushy grilled vegetables happen from overcooking, slicing too thin, or using vegetables that don't hold up on the grill. Excess moisture (not patting dry) also causes steaming instead of grilling.

How to Fix It

  1. Slice thick: 1.5-2cm for most vegetables
  2. Pat dry with paper towel before oiling — surface moisture steams
  3. Use high heat for a quick char — don't let them sit on the grill too long
  4. Choose sturdy vegetables: capsicum, zucchini, eggplant, corn, mushrooms, sweet potato
  5. Use a grill basket for small or delicate pieces
  6. Don't crowd the grate — space between items prevents steaming
  7. Oil the vegetables, not the grate
