To toast coconut in the microwave, spread the coconut evenly over a microwave-safe dish, and microwave on high for about four to eight minutes or until golden brown. Occasionally toss the coconut with a fork to reduce the risk of burning.
KingArthurFlour.com offers a recipe for toasting coconut in the microwave. This recipe recommends toasting the coconut on high in 30 second increments to ensure that the coconut browns evenly and does not burn. Place 1/2 a cup of shredded coconut on a microwave-safe plate, and microwave on high for 30 seconds at a time until it starts to brown. Continue cooking in 30 second bursts, stirring after each burst to evenly distribute the heat. Remove the coconut from the microwave when it reaches a consistent golden brown color.
