Over high heat, bring the chicken stock to a boil in a 3 quart or more pot. Add the quinoa and stir. Allow the quinoa to boil for 5 minutes. Then, turn the heat off and cover the pot with a well-fitted lid.
Let the quinoa sit covered for 30 minutes until the chicken stock is fully absorbed— do not remove the lid.
Once cooked, remove the lid and fluff with a fork.
Notes
Make Ahead Instructions: Quinoa can be made in advance and refrigerated for up to 1 week. It can also be frozen for up to 3 months— make sure it's completely cooled before freezing. Thaw overnight in the refrigerator.
Quinoa: If the quinoa you buy doesn't say "rinsed" make sure you rinse it.
Chicken Stock: I find that stock (chicken, beef or vegetable) gives the best flavor, but you can use water as a substitute.
