Ingredients
- 2 large boneless skinless chicken breasts (about 1 1/2 lb), cooked and shredded (or 3 cups rotisserie chicken)
- 1 cup uncooked quinoa, rinsed well
- 2 cups broccoli florets (fresh or frozen, thawed and drained)
- 1 can (10.5 oz) reduced-sodium cream of chicken soup
- 1/2 cup plain Greek yogurt (2% or nonfat)
- 1/2 cup low-sodium chicken broth
- 1 cup shredded sharp cheddar cheese, divided
- 1 tablespoon olive oil
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon kosher salt, plus more to taste
- 1/4 teaspoon black pepper
- 1/2 cup panko breadcrumbs (optional, for crispy topping)
- 1 tablespoon melted butter or olive oil (optional, for topping)
Pro tip: Rinse quinoa under cold water until the water runs clear—this removes bitterness and helps grains stay fluffy after baking.
Equipment
- Medium saucepan for quinoa
- Steamer basket or microwave-safe bowl for broccoli
- 9×9-inch baking dish (or 2-quart casserole dish)
- Large mixing bowl
- Aluminum foil
Step-by-Step Instructions
Step 1: Cook the Quinoa (15 minutes)
Combine rinsed quinoa with 2 cups water in a medium saucepan. Bring to a boil, reduce heat to low, cover, and simmer 14–16 minutes until water is absorbed and quinoa is tender with a slight bite. Remove from heat, fluff with a fork, and leave covered 5 minutes.
Step 2: Steam the Broccoli (7 minutes)
While quinoa cooks, steam broccoli florets until bright green and fork-tender, about 5–7 minutes. If using frozen broccoli, microwave or steam per package directions and drain thoroughly—excess water makes the casserole soggy.
Step 3: Make the Creamy Sauce (3 minutes)
In a large bowl, whisk together cream of chicken soup, Greek yogurt, chicken broth, garlic powder, onion powder, salt, and pepper until smooth. Taste and adjust seasoning; add a pinch of cayenne if you want gentle heat.
Step 4: Assemble the Casserole (5 minutes)
Preheat oven to 375°F (190°C). Lightly grease a 9×9-inch baking dish with olive oil. Spread cooked quinoa evenly on the bottom. Top with shredded chicken, then broccoli. Pour the creamy sauce over everything and gently spread to coat. Sprinkle with 3/4 cup cheddar cheese.
Step 5: Bake Until Bubbly (25–35 minutes)
Cover tightly with foil and bake 20–25 minutes until the center is hot. Remove foil; if using breadcrumbs, toss panko with melted butter and scatter over the cheese. Bake uncovered 5–10 minutes more until cheese is golden and edges bubble. Rest 5 minutes before serving.
Step 6: Serve
Divide into six portions and serve warm. A simple side salad or roasted carrots round out the plate without adding another pot to wash.
Serving Suggestions
- Light lunch: Pair with cucumber tomato salad and lemon wedges.
- Comfort dinner: Add garlic bread and steamed green beans.
- Meal prep: Pack portions with a small container of hot sauce for variety through the week.
Tips for the Best Casserole
- Drain vegetables well: Wet broccoli dilutes the sauce and extends bake time.
- Do not skip the rest: Cutting immediately makes layers slide apart on the plate.
- Cheese layer: Reserve a little cheddar for the last 5 minutes for maximum melt.
- Rotisserie shortcut: Shredded store-bought chicken cuts prep time in half.
Storage, Reheating, and Freezing
Refrigerate cooled leftovers in airtight containers up to 4 days. Reheat single portions in the microwave covered, stirring halfway, or warm the whole dish at 350°F until heated through.
Freeze baked portions up to 2 months. Thaw overnight in the refrigerator and reheat with a splash of broth to restore creaminess.
Substitutions and Variations
- More veggies: Stir in diced carrots, spinach, or peas with the broccoli.
- Dairy-free: Use dairy-free yogurt, cheese shreds, and cream-style soup alternatives.
- Gluten-free: Choose a gluten-free cream soup and skip breadcrumbs or use GF panko.
- Spicier: Add diced jalapeño or a dash of hot sauce to the creamy mixture.

Frequently Asked Questions
Can I use pre-cooked quinoa?
Yes. You need about 3 cups cooked quinoa. Skip the stovetop step and layer it directly in the baking dish.
Is chicken quinoa broccoli casserole healthy?
It balances lean protein, whole-grain quinoa, and vegetables with a lighter creamy sauce thanks to Greek yogurt—lighter than traditional heavy-cream casseroles but still satisfying.
Why is my casserole watery?
Usually undrained broccoli or frozen vegetables that were not thawed and patted dry. Drain well and bake uncovered during the final minutes to evaporate extra moisture.
Can I assemble this casserole ahead of time?
Assemble unbaked, cover, and refrigerate up to 24 hours. Add 10–15 minutes to the covered bake time if the dish goes in cold from the fridge.
What can I use instead of cream of chicken soup?
Homemade béchamel with chicken broth, or a can of cream of mushroom soup for a different flavor profile. Adjust salt because canned soups vary.
Can I double the recipe?
Double all ingredients and use a 9×13-inch baking dish. Increase covered bake time by about 10 minutes and check that the center reaches 165°F if using raw chicken layers.
