Essential Ingredients for Your Greek Chicken Casserole

For precise quantities and detailed step-by-step instructions, please refer to the recipe card below.
To embark on this delicious Greek culinary journey, gather the following key ingredients. Each plays a vital role in creating the casserole’s signature flavor and texture:
- Rotini Pasta: Approximately 8 ounces (about 3 cups) of rotini pasta forms the hearty base. Its corkscrew shape is perfect for capturing and holding onto the rich sauce and small bits of cheese and vegetables, ensuring every bite is bursting with flavor. Other ridged pasta shapes like fusilli or radiatore would also work beautifully.
- Cooked Chicken: About 3-4 cups of cooked chicken, either cubed or shredded. This is where the rotisserie chicken shines, offering both convenience and incredible flavor. If you don’t have rotisserie chicken, leftover roasted chicken, or even poached chicken breasts can be quickly prepared and shredded.
- Tomato Sauce: A large 29-ounce can of good quality tomato sauce provides the foundational rich, tangy flavor. Look for a brand with minimal added sugar for the purest taste.
- Diced Tomatoes: One 14-ounce can of diced tomatoes, thoroughly drained, adds texture and a fresh, bright tomato acidity to the sauce. Draining is key to prevent the casserole from becoming watery.
- Frozen Spinach: 10-12 ounces of frozen spinach, thawed and carefully squeezed dry. This step is crucial. Excess moisture from spinach can make your casserole soggy, so squeeze out as much liquid as possible for a perfectly textured dish.
- Kalamata Olives: Half a cup of sliced Kalamata olives. These Greek staples bring a distinct briny, slightly fruity, and savory depth that is essential to the Mediterranean profile of the dish.
- Red Onion: A quarter cup of thinly sliced red onion adds a subtle sharp, sweet bite, complementing the other robust flavors.
- Green Bell Pepper: A quarter cup of chopped green bell pepper provides a fresh, slightly bitter crunch and vibrant color.
- Dried Basil & Oregano: One teaspoon each of dried basil and dried oregano. These herbs are the aromatic heart of Greek and Mediterranean cuisine, infusing the casserole with their characteristic fragrant notes. Using good quality, fresh dried herbs will make a noticeable difference.
- Mozzarella Cheese: One cup of shredded mozzarella cheese for that classic gooey, melty top and mild creaminess throughout.
- Feta Cheese: Half a cup of crumbled feta cheese. This is the star cheese, offering its signature salty, tangy, and crumbly texture that truly defines the Greek essence of the casserole. Don’t skimp on good quality feta!
Effortless Preparation: How to Make this Greek Chicken Casserole
One of the greatest joys of preparing casseroles is that much of the groundwork, particularly cooking the components, can be done ahead of time. This inherent convenience makes meal preparation a truly effortless endeavor.
- Prepare Your Oven and Pan: Begin by preheating your oven to 400°F (200°C). As it warms, lightly spray a 13×9-inch baking pan with cooking spray. This crucial step prevents sticking and ensures easy serving.
-
Cook the Pasta: Cook your rotini pasta according to the package directions until it’s al dente – tender, but still firm to the bite. While rotini is my preferred choice for its excellent ability to hold sauce in its ridges, feel free to use any pasta with a similar texture-grabbing surface, such as fusilli or radiatore. Once cooked, drain the pasta thoroughly and set it aside.

- Prepare the Vegetables and Spices: While the pasta boils, efficiently prep the remaining ingredients. Dice your green bell pepper and thinly slice the red onion. If using frozen spinach, place it in a microwave-safe bowl and heat for a couple of minutes to thaw. Once thawed, and this is a critical step, squeeze out as much excess liquid as possible. Use a clean kitchen towel or paper towels to ensure the spinach is as dry as possible; this prevents a watery casserole. Measure out your dried basil and oregano.
-
Combine All Ingredients (Except Cheese): In a large mixing bowl, combine the cooked and drained pasta with the cooked chicken, tomato sauce, drained diced tomatoes, squeezed dry spinach, sliced Kalamata olives, sliced red onion, chopped green bell pepper, dried basil, and dried oregano. Stir everything gently but thoroughly until all components are evenly distributed and coated in the delicious tomato sauce.

- Assemble the Casserole: Transfer the vibrant casserole mixture into your prepared 13×9-inch baking pan, spreading it out evenly.
-
Add the Cheeses: Now for the crowning glory! Evenly sprinkle the crumbled feta cheese over the entire surface of the casserole. Its sharp, salty notes will perfectly complement the rich tomato base. Follow with a generous layer of shredded mozzarella cheese, which will melt into a beautiful, golden-brown crust.

-
Bake to Perfection: Place the uncovered dish into your preheated oven. Bake for approximately 25 minutes, or until the casserole is heated through, the cheese is beautifully melted and bubbly, and the edges are golden. The aroma filling your kitchen will be irresistible!

- Serve Immediately: Once baked, remove the casserole from the oven and let it rest for a few minutes to allow the flavors to meld and the cheese to set slightly. Then, it’s ready to be served and enjoyed!
Serving Suggestions to Complete Your Meal
This Greek Chicken Casserole is a robust and complete meal on its own, but pairing it with complementary sides can elevate the dining experience. For a truly satisfying accompaniment, serve it alongside fluffy rice or nutritious quinoa to soak up every last drop of the flavorful juices. Alternatively, a slice of warm, crusty garlic bread (vegan or traditional) is always a welcome addition, perfect for scooping up the rich sauce.
To add a refreshing contrast and lightness, consider a simple green salad with a bright vinaigrette. For an even more authentic Mediterranean touch, a traditional Greek salad featuring crisp cucumber, thinly sliced red onion, ripe tomatoes, and more crumbled feta cheese, dressed with olive oil and a squeeze of lemon, would beautifully complement the main dish. Steamed or roasted green vegetables like broccoli or asparagus also make excellent, healthy companions. Pair it with a crisp white wine or a refreshing iced tea for a complete meal.

Customizing Your Casserole: Substitutions and Variations
This recipe is wonderfully adaptable, allowing for various substitutions and creative variations to suit your taste preferences or whatever ingredients you have on hand.
- Chicken Alternatives: If you don’t have leftover rotisserie chicken, you can easily cook up some **ground chicken or turkey** with a dash of olive oil and seasonings before adding it to the casserole. Diced cooked chicken breast or thigh meat also works perfectly. For a richer flavor, consider using cooked dark meat chicken.
- Vegetarian Version: To transform this into a delightful vegetarian main, simply **omit the chicken** entirely. Boost the vegetable content with additions like sautéed zucchini, eggplant, mushrooms, or even a can of chickpeas for added protein and texture.
- Cheese Choices: While feta is undeniably key to the Greek flavor profile, if you’re out or prefer a different taste, you can substitute with creamy **ricotta cheese** for a milder profile or pungent **goat cheese** for a tangier kick. A blend of parmesan and provolone could also offer an interesting twist.
- Vegetable Additions: Don’t hesitate to incorporate other vegetables. Blanched kale, finely diced carrots, or sun-dried tomatoes can add extra nutrients and flavor. Just remember to pre-cook firmer vegetables to ensure they are tender by the time the casserole finishes baking.
- Spice Adjustments: Feel free to adjust the herbs and spices. A pinch of red pepper flakes can add a subtle heat, while a touch of fresh dill or parsley, added at the end, can brighten the flavors. A squeeze of lemon juice before serving can also enhance the Mediterranean zest.
- Pasta Type: Beyond rotini, fusilli, and radiatore, penne or ziti are also good options for this baked pasta. For a healthier alternative, consider using **whole wheat pasta**.
Storage and Meal Prepping Tips
This Greek Chicken Casserole recipe yields a generous amount, making it perfect for meal prepping or enjoying delicious leftovers.
- Refrigeration: Store any leftover casserole in an airtight container in the refrigerator for up to **3-4 days**. This ensures the flavors remain fresh and the dish stays safe to eat.
- Reheating: When ready to enjoy, simply reheat individual portions in the microwave until warmed through. For larger portions or to restore some of the crispy cheese topping, reheat in a preheated oven at 350°F (175°C) for 15-20 minutes, or until bubbling and hot.
- Freezing (Cooked): Yes, this casserole freezes beautifully! Allow the cooked casserole to cool completely. Divide it into individual portions or leave it whole in a freezer-safe dish. Wrap tightly with plastic wrap, then with aluminum foil to prevent freezer burn. It can be stored in the freezer for up to **3 months**. Thaw overnight in the refrigerator before reheating.
- Freezing (Uncooked): For a fantastic make-ahead meal, you can assemble the casserole (without baking) and freeze it. Wrap it just as you would the cooked version. To bake from frozen, remove the plastic wrap and foil, and bake in a preheated oven at 375°F (190°C) for 45-50 minutes, or until heated through and bubbly. You might want to cover it with foil for the first 30 minutes to prevent the top from browning too quickly, then uncover for the last 15-20 minutes to melt and brown the cheese.
