Ingredients

  • 5 cups peeled and diced sweet potatoes
  • 1 tablespoon avocado oil or high heat oil of choice, divided
  • 1 medium yellow onion finely diced
  • 1 red pepper diced
  • 1 tablespoon fresh thyme chopped
  • 1 tablespoon minced garlic
  • 1 cup quinoa rinsed
  • 1 ¾ cups vegetable broth
  • 1 ½ teaspoons sea salt
  • ½ teaspoon fresh ground black pepper
  • ¼ teaspoon cayenne pepper
  • 2 eggs beaten (optional)
  • ½ cup milk of choice
  • 6 ounces Gruyere cheese grated or vegan shreds

Instructions

  • Preheat oven to 400 degrees. Line a baking sheet with parchment paper.
  • In a medium bowl, toss together sweet potatoes and ½ tablespoon of oil. Season to taste with salt and pepper. Arrange in a single layer on the prepared baking sheet. Bake for 12 minutes.
  • Heat the remaining oil over medium heat. Add onion, red pepper and thyme and cook for 8 minutes, until the onion is tender. 
  • Add garlic, quinoa and sweet potatoes and stir for a minute.
  • Add broth, salt, black pepper and cayenne pepper. Bring to a simmer and then reduce the heat to low. 
  • Cover and cook on low for 25 minutes, or until most of the liquid is absorbed. Stir. Remove from heat and allow to sit covered for 5 minutes.
  • Transfer the quinoa mixture to an 8 x 8 baking dish. In a small bowl, whisk together eggs and milk. Pour over the quinoa. Top with cheese.
  • Bake at 350 degrees for 30 minutes. If desired, broil for two minutes to brown the top.

Notes

Tips for Making Quinoa and Sweet Potato Casserole

  • To make a vegan quinoa casserole, omit the eggs and use unsweetened almond milk and vegan cheese.

Variations for Sweet Potato Quinoa Casserole

  • For a more hearty meal, stir in 16 ounces of cooked shredded chicken prior to baking.
  • For additional vegetarian protein, add in 1 ½ cups (one can) of cooked, drained and rinsed black beans before baking.
  • Add 10 ounces of sautéed baby Bella mushrooms and 1 ½ cups cooked, drained and rinsed cannelloni beans prior to serving.
  • For a sweet twist, omit the cheese topping. Instead, meant ¼ cup butter in a small saucepan. Whisk in ¼ cup brown sugar until well combined. Remove from heat and sit in 1 cup oats, ⅔ cup toasted pecans, 1 tablespoon of gluten free flour and ½ teaspoon sea salt. Sprinkle over quinoa casserole and bake as directed.
