Broccoli Quinoa Chicken Cheese

My neighbor stopped by one Tuesday evening just as I was pulling this casserole from the oven, and the aroma alone had her asking for the recipe before she even tasted it. There's something about the way broccoli caramelizes at the edges and cheese bubbles into golden pockets that makes a kitchen feel like home. This dish came together almost by accident when I had leftover rotisserie chicken, a container of quinoa, and broccoli that needed using before the weekend. It turned out to be exactly the kind of meal that works for lunch boxes, dinner tables, and freezer emergencies all at once.

I made this for a potluck at work once, and it traveled in the car perfectly—stayed warm the whole way, and people actually asked if I'd bought it from somewhere nice. The compliments felt even better because I knew it cost less than takeout and took barely more time than ordering delivery.

Ingredients

• Cooked quinoa (2 cups, about 3/4 cup dry): This grain adds a subtle nuttiness and fluffy texture that feels lighter than rice but just as satisfying; cook it according to package directions and let it cool slightly so it doesn't break apart when mixed.
• Cooked chicken (2 cups, shredded or diced): Rotisserie chicken from the store saves time and adds incredible flavor, but homemade works just as well; make sure it's cooled before adding to avoid cooking the egg prematurely.
• Large egg (1): This acts as a gentle binder that helps everything hold together without making the casserole dense or heavy.
• Broccoli florets (3 cups, steamed until just tender): The key is steaming just until bright green and crisp-tender; over-cooked broccoli turns soft and loses that fresh flavor that makes this dish special.
• Shredded cheese, divided (2 cups total, cheddar, mozzarella, or a blend): Using half in the mixture and half on top creates layers of flavor and gives you that irresistible melted golden crust.
• Chicken stock (1/2 cup, low sodium if preferred): This keeps everything moist as it bakes and adds savory depth without overpowering the other flavors.
• Dried basil (1/2 teaspoon): A whisper of herbaceous flavor that lifts the entire dish.
• Dried oregano (1/2 teaspoon): Adds an earthy warmth that ties all the ingredients together.
• Salt and black pepper (1/4 teaspoon each): Taste as you go; you might want a tiny pinch more depending on how salty your stock and cheese are.

Instructions

Set your stage:

Preheat the oven to 350°F (175°C) and lightly grease a 9 x 9-inch baking dish with oil or nonstick spray. Having everything ready before you start mixing makes the whole process feel smooth and calm.

Prepare your components:

If your quinoa isn't cooked yet, do that now and let it cool slightly while you work. Steam the broccoli florets in about 1/2 inch of water, covered, for 3 to 5 minutes until the florets are bright green and tender but still have a tiny bit of resistance when you bite them—drain it well so excess water doesn't water down the final dish.

Build the mixture:

In a large mixing bowl, combine the cooled quinoa, cooked chicken, steamed broccoli, egg, chicken stock, 1 cup of the shredded cheese, basil, oregano, salt, and pepper. Stir gently until everything is evenly distributed; you want the egg to act as a quiet binder, not scrambled bits, so mix with intention but not aggression.

Transfer and layer:

Pour the mixture into your prepared baking dish and press it down gently to create an even layer. Sprinkle the remaining 1 cup of cheese evenly over the top, making sure you get some coverage all the way to the edges so every bite has that golden cheesy goodness.

Bake covered, then uncover:

Cover the dish tightly with foil and bake for 30 minutes; this traps steam and keeps everything moist. Remove the foil and bake for another 5 to 10 minutes until the cheese is melted, bubbly, and starting to turn golden at the edges.

Rest and serve:

Let the casserole sit for 5 minutes before cutting—this gives the structure a chance to set so you get clean portions instead of a crumbly mess. Scoop it into bowls and serve while it's still steaming.

There was a moment when my teenager actually asked for seconds of a vegetable dish without any eye-rolling, and that's when I knew this recipe had truly crossed into something special. It's the kind of meal that proves eating well doesn't have to feel like sacrifice.

Make-Ahead Magic

One of the best features of this casserole is that you can assemble it the night before and just pop it in the oven when you get home. I love covering it tightly with plastic wrap and letting it sit in the fridge overnight; if anything, the flavors deepen as they mingle. Just add about 5 extra minutes to the baking time if it goes straight from cold fridge to hot oven.

Freezing for Future You

This is where the casserole really earns its place in my regular rotation. Assemble it unbaked in a metal baking dish (aluminum disposables work perfectly), wrap it super well with plastic wrap and then foil, and freeze for up to three months. When you're ready to bake, thaw it completely in the refrigerator overnight and follow the regular baking instructions as if it were freshly made.

Variations and Tweaks

The beauty of this casserole is how forgiving it is when life gets creative. I've made vegetarian versions by leaving out the chicken entirely and adding sautéed mushrooms or extra broccoli, and nobody at the table noticed anything was missing. You can lighten it up with part-skim cheese or reduce the total cheese amount if you're watching fat intake. For a different flavor profile, try swapping the Italian herbs for cumin and chili powder, or use sharp cheddar instead of mild for a more pronounced taste.

• Vegetarian version: omit chicken and add sautéed mushrooms, extra broccoli, or even diced sweet potato for substance.
• Make it lighter: use part-skim cheese or reduce cheese to 1.5 cups total and add an extra 1/4 cup stock for moisture.
• Storage tip: leftovers keep in the fridge for up to 4 days and reheat beautifully covered at 350°F (175°C) until hot throughout.
