Nutrition Benefits Of Using Quinoa

We picked quinoa because it is easy to prepare, cooks quickly, and there are so many delicious ways to use it. While quinoa is technically a seed, it has a similar nutrient profile to whole-grains so it’s often considered a grain. Research indicates that consumption of whole grains is associated with reduced risk of diseases such as cardiovascular disease, diabetes, and cancer. 

Quinoa is high in fiber, protein, and minerals like magnesium and folate. Studies have shown that consumption of quinoa is associated with improved lipid profiles, weight loss, and improved glycemic control. Additionally, quinoa is a delicious gluten-free option for individuals who need to avoid gluten. The quinoa in this chicken quinoa casserole adds a great texture and flavor. 

Lightened Up Creamy Casserole

Creaminess often comes from butter, cream and other foods that are high in saturated fat. This cheddar chicken bake is made with low fat milk, greek yogurt, and a little cheddar cheese to keep the saturated fat content lower and instead boost the protein and calcium content. Using greek yogurt for dips and sauces is a great trick to create a thick, creamy texture without adding unhealthy fats. For this recipe, try using a low-fat, plain greek yogurt.

How To Make This Easy Chicken Quinoa Casserole

Wash and cut the broccoli into bite size pieces, then toss with oil and place on parchment paper on a baking sheet. Roast the broccoli for 15-20 minutes at 400°F. While the broccoli roasts, cook the quinoa in a pot according to the directions on the package. Heat a non-stick pan with oil. Toss the chicken with salt and pepper and then add to the skillet to saute until completely cooked. Lower the oven temperature to 350°F. In a bowl, combine the quinoa, milk, yogurt, half of the cheese, and red pepper flakes. Add in the chicken and broccoli. Mix well and then pour into a baking dish. Sprinkle with the rest of the cheddar cheese and breadcrumbs. Bake for 15-20 minutes. Enjoy!
