Rinse quinoa in a fine-mesh strainer under cool running water for at least 30 seconds, then drain well. Skipping this removes saponin, which causes a bitter, soapy taste. Use a 1:2 ratio of dry quinoa to liquid. Water works fine; broth adds deeper flavor. Optional: toast rinsed, dried quinoa in a dry skillet with a little olive oil or butter over medium heat, stirring frequently for 1 to 2 minutes until fragrant and lightly golden, then transfer to the cooker. Lightly grease the rice cooker bowl with butter or cooking spray. Add measured quinoa and liquid to the rice cooker and you are ready to cook.

Add rinsed quinoa and measured liquid to the greased rice cooker bowl and close the lid. Set to the white rice or standard cook cycle. Total cook time is 18 to 25 minutes depending on your model and quantity. Do not open the lid during cooking, as releasing steam disrupts absorption and leads to uneven grains. The quinoa is done when the grains look fluffy and the small spiral tails, called endosperms, visibly curl away from each seed. When the cooker switches to warm, resist opening the lid. Let the quinoa rest on the warm setting, lid closed, for 5 to 10 minutes. This rest finishes the grains evenly and produces a fluffier result. Skipping it often leads to dense or gummy texture.

Open the lid and fluff the quinoa with a fork using light lifting motions, not stirring. Properly cooked quinoa is light, fluffy, and slightly firm with a gentle bite. Each grain should show a small curled tail pulled away from the seed body. If liquid remains at the bottom, close the lid and let it sit on warm a few more minutes before fluffing again. If it seems dry or undercooked, add a small splash of water, close the lid, and steam a few more minutes. One cup dry yields about 3 cups cooked. Cool slightly before adding to cold dishes, or serve warm as a side or grain bowl base. Store leftovers in an airtight container in the fridge.
