Ingredients

2 cups cooked quinoa
2 cups cooked chicken
3 cups steamed broccoli
1 egg
1/2 cup chicken stock
2 cups shredded cheese, divided
1/2 teaspoon dried basil
1/2 teaspoon dried oregano
1/4 teaspoon salt
1/4 teaspoon pepper

Instructions

Step 1: Cook the quinoa according to package directions using your preferred method such as stovetop, rice cooker, or Instant Pot.
Step 2: Steam the broccoli by heating ½ inch of water in a pan or pot. Add the broccoli florets, cover, and steam for 3–5 minutes until the broccoli is bright green and tender in the middle.
Step 3: Preheat your oven to 350°F. Lightly oil a deep 9 x 9 inch baking dish and set aside.
Step 4: In a large bowl, combine the cooked quinoa, cooked chicken, steamed broccoli, egg, chicken stock, half of the shredded cheese, dried basil, dried oregano, salt, and pepper. Mix well.
Step 5: Press the mixture evenly into the prepared baking dish. Sprinkle the remaining cheese evenly on top.
Step 6: Cover the baking dish and bake for 40 minutes. Then remove the cover and bake uncovered for an additional 5–10 minutes until the cheese is melted and lightly browned.
Step 7: Let the casserole cool slightly before serving. Portion into bowls and enjoy your hearty meal!

Tips & Variations

Use leftover roasted chicken or rotisserie chicken for a quick prep.
For extra creaminess, add a splash of cream or a dollop of sour cream to the mixture before baking.
Try swapping the broccoli for cauliflower or green beans for a different vegetable option.
Use a sharp cheddar or a blend of cheeses to enhance the flavor.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or warm the casserole in the oven at 350°F until heated through, about 15–20 minutes.
