There’s something wonderful about settling into the rhythm of making a baked casserole on a chilly evening.
As the sauce thickens on the stove and the quinoa begins to swell in the oven, the whole kitchen fills with the comforting aroma of chicken, herbs, and real, simple ingredients coming together.
Your kitchen feels warm, the air smells cozy, and you know a satisfying meal is on its way.
It’s the kind of dish that feels both grounding and generous—hearty enough for the end of a long day, yet wholesome enough to enjoy all week long.
Lately, this creamy chicken, quinoa, and broccoli bake has been a steady favorite.
It’s creamy without being heavy, made completely from scratch, and packed with protein, veggies, and that just-right texture that makes casseroles so comforting.
Assemble it in one dish, slide it into the oven, and let the warmth do the rest.
Dinner becomes easy, nourishing, and wonderfully comforting—exactly the kind of meal that makes weeknights feel a little softer.
For the Casserole Base
- Chicken Broth – Forms the foundation of the creamy sauce while keeping sodium in check since it’s reduced-sodium.
- Milk (2%) – Adds richness and helps create the smooth, velvety texture in the sauce.
- Poultry Seasoning – Brings savory, herby depth that pairs perfectly with chicken.
- Flour – Thickens the sauce to make it creamy without relying on canned soups.
- Water – Used in stages to cook the quinoa and adjust consistency at the end.
- Quinoa (uncooked, rinsed) – The wholesome grain that cooks directly in the casserole, absorbing all the flavors.
For the Chicken Layer
- Boneless Skinless Chicken Breasts – Sliced thin so they cook evenly on top of the casserole.
- Seasoning Blend – A simple all-purpose seasoning (like Emeril’s Essence) adds flavor and color to the chicken.
For the Veggies & Topping
- Fresh Broccoli Florets – Blanched briefly for vibrant color and ideal texture before mixing into the finished bake.
- Shredded Gruyere Cheese – Melts beautifully over the top; any good melting cheese works here.

Ingredients
-
2 cups reduced-sodium chicken broth
-
1 cup 2% milk
-
1 teaspoon poultry seasoning
-
1/2 cup flour
-
2 cups water, divided
-
1 cup uncooked quinoa, rinsed
-
1 pound boneless skinless chicken breasts
-
2 teaspoons seasoning (such as Emeril’s Essence or any general-purpose blend)
-
1/4 cup shredded Gruyere cheese (any melting cheese works)
-
3 cups fresh broccoli florets
-
Preheat your oven to 400°F and generously grease a 9×13-inch baking dish.
-
In a saucepan, heat 2 cups chicken broth and 1/2 cup milk until just starting to simmer.
-
In a separate bowl, whisk together the remaining 1/2 cup milk, 1/2 cup flour, and 1 tsp poultry seasoning until smooth.
- Slowly pour this mixture into the simmering broth while whisking constantly. Cook until the sauce thickens and is creamy.
-
In a large bowl, combine the cream sauce, 1 cup water, and rinsed quinoa.
-
Pour the mixture into the prepared baking dish.
-
Slice 1 lb chicken breasts thinly and lay them evenly over the quinoa mixture.
-
Sprinkle the chicken with 2 tsp seasoning.
- Bake uncovered for 30 minutes.
-
While the casserole bakes, bring a pot of water to a boil.
-
Blanch 3 cups broccoli florets for 1 minute, until bright green.
-
Drain and run the broccoli under cold water to stop cooking. Set aside.
- Finish Baking
-
Take the casserole out of the oven and give it a stir. If it’s still too liquidy, bake uncovered for another 10–15 minutes.
-
Stir in the broccoli and add up to 1 cup water if needed to loosen the mixture and make it creamy.
- Sprinkle 1/4 cup shredded Gruyere cheese on top and bake for 5 more minutes, until the cheese melts.
- Do I need to pre-cook the quinoa or chicken?
Nope! The quinoa cooks right in the casserole and the chicken strips bake on top. Just slice the chicken thin so it cooks evenly. Easy-peasy.
- Why is my casserole watery after baking?
This happens sometimes. Make sure you’re using a 9×13 pan — anything bigger will spread the liquid too thin. After the first 30 minutes, give it a stir and if it’s still loose, bake uncovered for another 10–15 minutes. That extra time lets the sauce thicken perfectly.
- Can I swap chicken breasts for thighs or use cooked chicken?
Absolutely. Thighs work just as well, and pre-cooked chicken is fine too — just reduce the bake time slightly and make sure it’s seasoned.
- How do I get the sauce creamy without it splitting or curdling?
Whisk the flour and milk together before adding to the hot broth — this keeps it smooth. Once the quinoa and chicken are cooked, stir in the broccoli and add just enough water (up to 1 cup) to make it creamy. Top with cheese and bake just until melted. No grainy sauce here!
- Can I make this ahead or store leftovers?
Yes! This casserole is perfect for meal prep. Store in the fridge for a few days, or freeze for longer. Reheat in the microwave or gently in a covered skillet with a splash of water so it doesn’t dry out.
