The beauty of a healthy quinoa casserole is its versatility. You can easily adjust the ingredients to fit your preferences or what you have on hand. The chicken and quinoa create a fantastic base, and the pesto is what brings all the flavors to life. When the casserole bakes, the cheese melts and forms a beautiful golden crust, while the tomatoes (if you choose to add them) burst with a sweet, tangy flavor that cuts through the richness.
👩🍳 Step-by-Step Instructions
Making this pesto chicken quinoa casserole is incredibly straightforward. The process is broken down into a few simple steps, ensuring a perfect result every time.
- Prep the Chicken and Veggies: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish. In a large skillet over medium-high heat, add the olive oil. Once hot, add the cubed chicken and cook until it’s browned on all sides. You don’t need to cook it all the way through, just get a nice sear. Remove the chicken from the skillet and set it aside.
- Sauté the Aromatics: In the same skillet, add the chopped onion and cook until it softens, about 5-7 minutes. Add the minced garlic and cook for another minute until it’s fragrant.
- Combine the Base: Add the rinsed quinoa and chicken broth to the skillet. Bring the mixture to a boil, then reduce the heat to a simmer, cover, and cook for about 15 minutes, until the quinoa has absorbed most of the liquid. It will finish cooking in the oven.
- Assemble the Casserole: Transfer the quinoa and onion mixture to the prepared baking dish. Stir in the cooked chicken and the basil pesto until everything is well combined. Season with salt and pepper to your taste. If you’re using cherry tomatoes, stir those in as well.
- Add the Cheese: Sprinkle the shredded mozzarella and grated Parmesan cheese evenly over the top of the casserole.
- Bake: Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the cheese is melted and bubbly and the casserole is heated through. The top should be a beautiful golden-brown color.
- Serve and Garnish: Carefully remove the casserole from the oven. Let it rest for a few minutes before serving. Garnish with fresh basil or a little extra Parmesan cheese.
The magic of this cheesy chicken and quinoa bake happens in the oven. The quinoa continues to absorb the flavors from the broth and pesto, becoming tender and perfectly cooked. The chicken stays juicy, and that cheese topping? It turns into a bubbly, irresistible crust that makes every bite feel like a treat. This is the kind of one-pot chicken meal that truly delivers on flavor and convenience.
🍽️ Serving Suggestions and Variations
This pesto chicken quinoa casserole is a complete meal on its own, but it’s always fun to get creative and see what other flavors you can add.
- Serving Suggestions: This dish pairs wonderfully with a crisp, green side salad dressed in a light vinaigrette. The freshness of the salad cuts through the richness of the casserole beautifully. A side of garlic bread would also be a fantastic addition to soak up all the delicious, savory flavors. For a drink pairing, a light-bodied white wine like a Sauvignon Blanc or a crisp Pinot Grigio would be a perfect match.
- Add More Veggies: Want to sneak in some more vegetables? You can easily add baby spinach, bell peppers, or zucchini to the skillet with the onions. They’ll wilt down as they cook, adding extra nutrients and color to the dish without changing the core flavor profile. Roasted red peppers from a jar also work well.
- Protein Swaps: Not a fan of chicken? No problem! You can easily swap the chicken for cooked turkey, shredded pork, or even chickpeas for a vegetarian version. If you go the vegetarian route, just make sure to use vegetable broth instead of chicken broth.
- Different Pesto, Different Vibe: The beauty of this recipe is that you can change the flavor just by swapping out the pesto. Try a sun-dried tomato pesto for a richer, sweeter flavor, or a cilantro-lime pesto for a zesty, fresh twist.
- Make it Creamier: For an extra creamy texture, you can stir in a half cup of Greek yogurt or a little cream cheese at the same time you add the pesto. This will make the quinoa casserole recipe even more indulgent.
This simple chicken casserole is incredibly forgiving and open to interpretation. It’s a great way to use up ingredients you have in the fridge and create something new and exciting every time.
🧐 Common Questions and Pro Tips
Why do I need to rinse the quinoa?
Rinsing quinoa is a super important step. Quinoa has a natural coating called saponin, which can give it a bitter, soapy taste if not washed off.1 A quick rinse under cold water in a fine-mesh sieve is all you need to do to get rid of it and ensure your casserole tastes delicious.
Can I use uncooked chicken?
For this recipe, it’s best to cook the chicken first. This ensures it’s cooked all the way through and gets a nice sear, which adds a lot of flavor. Plus, it makes sure you don’t end up with any raw chicken in your finished dish. If you’re using leftover cooked chicken, you can skip the searing step and just toss it in with the quinoa.
How do I store leftovers?
This easy casserole recipe is fantastic for leftovers! Simply store any remaining casserole in an airtight container in the refrigerator for up to 3-4 days. You can easily reheat a portion in the microwave or in a small baking dish in the oven until it’s warmed through. It’s a great option for healthy lunches throughout the week.
Can I freeze this casserole?
Yes! You can definitely freeze this casserole. After baking and cooling completely, you can wrap the entire dish tightly with plastic wrap and foil and freeze for up to 3 months. When you’re ready to eat it, let it thaw in the refrigerator overnight and then bake at 350°F (175°C) until it’s hot and bubbly. You can also freeze individual portions in separate containers, making it perfect for quick, single-serving meals.2
🌟 Pro Tips
- Don’t Overcook the Quinoa: Remember, the quinoa will continue to cook in the oven, so you don’t need to cook it all the way through on the stovetop. Just until most of the liquid is absorbed is perfect.
- Season as You Go: Add a pinch of salt and pepper when you cook the chicken and again when you combine all the ingredients. Building layers of seasoning is a simple way to boost the overall flavor of your dish.
- Get Creative with Toppings: Besides the cheese, you can top this casserole with toasted pine nuts, a drizzle of lemon juice, or even a sprinkle of red pepper flakes for a little heat.
- Use Good Broth: Using a high-quality chicken broth will give your casserole a richer, more robust flavor. It makes a bigger difference than you might think!
