-
1/4 cup breadcrumbs (optional, for topping)
-
1 tablespoon olive oil or melted butter (optional, for topping)
This recipe is highly flexible, making it great for customizing based on what you have on hand.
Kitchen Equipment You’ll Need
To whip this up with ease, make sure you have the following on hand:
-
Medium saucepan
-
Large mixing bowl
-
Measuring cups and spoons
-
9×13-inch casserole dish
-
Fork (for fluffing quinoa)
-
Spoon or spatula (for mixing)
-
Aluminum foil (optional, to cover while baking if needed)
Step-by-Step Directions
-
Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish with butter or nonstick spray.
-
Cook the quinoa: In a medium saucepan, bring the rinsed quinoa and water (or broth) to a boil. Reduce heat, cover, and simmer for about 15 minutes, or until the liquid is fully absorbed. Fluff with a fork.
-
Steam the broccoli: While the quinoa is cooking, steam the broccoli lightly. You can do this in the microwave or over the stove. Just make sure it’s vibrant green and tender but not mushy.
-
Mix everything together: In a large mixing bowl, combine the cooked quinoa, chicken, steamed broccoli, cheddar cheese, Parmesan, Greek yogurt, milk, garlic powder, onion powder, salt, and pepper. Stir until evenly combined.
-
Transfer to casserole dish: Pour the mixture into your greased casserole dish and spread evenly.
-
Add topping (optional): If you’re using the breadcrumb topping, mix the breadcrumbs with olive oil or melted butter, then sprinkle over the top.
-
Bake: Bake uncovered for 25–30 minutes, or until the casserole is heated through and the top is golden and bubbly.
-
Let it rest: Remove from oven and let rest for about 5 minutes before serving. This helps the casserole set slightly and makes it easier to scoop.
Recipe Notes and Tips
-
Shortcut alert: Use rotisserie chicken to save time on prep.
-
Flavor boost: Sub water for low-sodium chicken broth when cooking the quinoa to add extra depth.
-
Make it gluten-free: Omit the breadcrumbs or use gluten-free breadcrumbs.
-
Lighter option: Use reduced-fat cheeses and Greek yogurt to lighten it up.
-
Make ahead: You can assemble the entire casserole ahead of time and refrigerate until ready to bake (up to 2 days in advance).
Storage and Leftovers
This casserole stores beautifully. Here’s how to make it last:
-
Fridge: Store in an airtight container for up to 4 days. Reheat in the microwave or oven until warmed through.
-
Freezer: Freeze individual portions or the entire casserole (before or after baking) for up to 3 months. If frozen before baking, thaw overnight in the fridge before baking as directed.
-
Reheat tip: Add a splash of milk before microwaving to restore creaminess.
Delicious Variations
-
Spicy kick: Add a pinch of red pepper flakes or diced jalapeños for heat.
-
Veggie boost: Toss in some diced bell peppers, mushrooms, or peas.
-
Different cheeses: Try gouda, mozzarella, or pepper jack for a twist.
-
Swap the protein: Sub cooked turkey, ham, or even tofu for the chicken.
What to Serve with This Casserole
Although this dish is a meal on its own, here are a few simple pairings that complement it beautifully:
-
Crisp green salad with a light vinaigrette
-
Garlic bread or crusty whole grain rolls
-
Sparkling water with lemon, or a light white wine like Sauvignon Blanc
Frequently Asked Questions
Can I make this casserole vegetarian?
Absolutely! Just skip the chicken and replace it with extra broccoli, chickpeas, or sautéed mushrooms for a protein-rich vegetarian version.
Can I use rice instead of quinoa?
Yes. Cooked brown or white rice will work well. You’ll need about 2 1/2 cups of cooked rice to substitute for the quinoa.
Can I double the recipe?
Yes, but use two 9×13-inch dishes or a large roasting pan. You may need to adjust baking time slightly.
Is this kid-friendly?
Definitely. The cheesy, creamy texture is super appealing to kids—just chop the broccoli finely if your little ones are veggie-averse.
How can I add more fiber or nutrients?
Add flaxseed, chia seeds, or a handful of spinach into the mix before baking.
