Honey (Best Option)
3/4 cup honey per 1 cup brown sugarHoney works well as a substitute because it contains fructose and glucose, which provide sweetness and help with browning through the Maillard reaction. Its liquid form also helps dissolve other marinade ingredients evenly.
When using honey, reduce other liquids slightly to maintain marinade consistency and avoid overpowering the marinade with honeyβs distinct flavor. Use a mild-flavored honey to keep the original marinade profile.
The final result will be slightly more moist and may have a subtle floral note, but it will maintain the essential sweetness and caramelization effects of brown sugar.
