  • 2 Tbsp. butter
  • 1 Tbsp. extra-virgin olive oil
  • 1/2 cup chopped yellow onion or shallots
  • 3 garlic cloves, minced
  • 3 Tbsp. all-purpose flour
  • 2 cups lower-sodium chicken broth
  • 1 cup whole milk
  • 1 tsp. poultry seasoning
  • 1 1/4 tsp. kosher salt, divided
  • 1 tsp. black pepper, divided
  • 1 cup shredded sharp cheddar cheese, divided
  • 1 cup dry (uncooked) quinoa
  • 1 lb. boneless skinless chicken breasts
  • 4 cups broccoli florets


  • Preheat oven to 375ºF.
    Heat butter and oil in a medium saucepan over medium heat. Add onion and garlic; cook 3 to 5 minutes, until soft. Stir in flour and cook 2 full minutes to remove raw flour taste.
    Slowly whisk in broth and milk; increase heat to bring mixture to a simmer. Simmer for 5 minutes, whisking often, until sauce thickens. Stir in poultry seasoning, 1 tsp. salt, 3/4 tsp. black pepper, and 1/2 cup of the shredded cheese. Remove from heat.
  • Cut chicken into small bite-sized pieces, and season with remaining 1/4 tsp. each of salt and black pepper.
    Grease a 4-quart casserole dish with cooking spray. Add quinoa, chicken, and broccoli to dish. Pour cheese sauce overtop and carefully stir, making sure all components are mostly submerged in sauce.
  • Bake for 40 minutes, stirring once halfway through, until the quinoa and chicken are cooked through.
    Remove from oven, stir again, and top with remaining 1/2 cup shredded cheese. Broil for 3 to 5 minutes, until the cheesy is bubbly and golden. Let sit for 5 to 10 minutes before serving.


  • To Store. Refrigerate in an airtight storage container for up to 4 days.
  • To Reheat. Rewarm leftovers in a small baking dish in the oven at 350ºF. Alternatively, you can rewarm individual portions in the microwave.
  • To Freeze. Freeze in an airtight freezer-safe storage container for up to 3 months. Let thaw overnight in the refrigerator before reheating.
    •  You can freeze either before or after baking it - just be sure your dish is freezer-safe.
