What is Creamy Chicken Quinoa Broccoli Casserole?
At its core, creamy chicken quinoa broccoli casserole is a combination of lean protein, whole grains, and cruciferous vegetables, all wrapped up in a delightful creamy sauce. You get tender chicken, fluffy quinoa, and vibrant green broccoli mingling together in a dish that is hearty yet wholesome.
The magic happens in the oven when it turns into a bubbly, golden delight that feels like a warm hug on a plate.

How to Make Creamy Chicken Quinoa Broccoli Casserole?
Creating this casserole is straightforward, but it requires attention to detail. You’ll enjoy a satisfying cooking experience as you transform these ingredients into a culinary delight. Let’s break it down into easy-to-follow steps.
Step-by-Step Instructions
Step 1: Preheat the Oven
First things first, let’s get that oven preheated to 375°F (190°C). This is crucial for ensuring your casserole cooks evenly and turns golden brown on top.
Step 2: Cook the Chicken
Next, season the boneless chicken breasts with the spice blend. In a large skillet over medium heat, sauté the chicken until it’s cooked through, about 6-7 minutes per side. Chicken should reach an internal temperature of 165°F (74°C). Then, remove the chicken, let it cool, and dice it into bite-sized pieces.
Step 3: Prepare the Quinoa
In the same skillet, add 1 cup of quinoa along with 2 cups of water. Bring it to a boil, then reduce the heat, cover, and let it simmer for about 15 minutes until all the water has been absorbed. Fluff it with a fork before setting it aside.
Step 4: Make the Sauce
For the creamy part, take a saucepan, whisk together 1/2 cup of flour and 1 cup of milk over medium heat. Gradually add in 2 cups of chicken stock, stirring continuously until the mixture thickens (about 5 minutes). Add garlic powder, smoked paprika, and the poultry spice blend.
Step 5: Combine Ingredients
In a large mixing bowl, combine the cooked chicken, quinoa, broccoli florets, and the creamy sauce. If you’re using crispy bacon, toss that in too. The cornucopia of flavors and textures will start to come together, forming a cohesive mix.
Step 6: Bake It Up
Transfer this mixture into a greased casserole dish. Sprinkle the 1/4 cup of shredded Gruyère cheese evenly on top. Cover with aluminum foil and pop it in the oven for 30 minutes. After that, remove the foil and bake for another 10-15 minutes until the top is golden and bubbly. Let it cool slightly before serving.
Tips
- Use Rotisserie Chicken: For a quicker prep, grab a rotisserie chicken from the deli. Shred it and mix it into your casserole for a shortcut.
- Blanch the Broccoli: For vibrant color and crisp-tender perfection, blanch your broccoli for a couple of minutes before mixing it in.
- Make It Ahead: Assemble the casserole a day ahead, cover it, and store it in the fridge. This helps the flavors meld together beautifully.
- Extra Cheese: If you love cheese, don’t hold back! Feel free to mix in some cheese throughout the casserole for an added richness.
- Add Other Veggies: Don’t hesitate to throw in other veggies like bell peppers or spinach. They’ll boost the nutrition and color of your dish.
How to Store Leftovers?
After indulging, store any leftovers in an airtight container in the fridge for up to 4 days. This casserole can be reheated easily in the microwave or the oven, just add a splash of milk to keep it creamy.
