Step‑by‑Step Instructions for Chicken and Spinach Casserole Step 1: Preheat the Oven Begin by preheating your oven to 350°F (175°C). This temperature ensures that the chicken and spinach casserole cooks evenly and develops a beautiful golden crust on top. While the oven heats up, gather your ingredients and prepare your baking dish for assembly. Step 2: Prepare the Baking Dish Lightly grease a 9×13-inch baking dish with cooking spray or a drizzle of olive oil. This prevents the casserole from sticking and makes for easier serving later. Lay the stale bread pieces evenly across the bottom of the dish, creating a solid base that will absorb all the flavors of the Chicken and Spinach Casserole. Step 3: Whisk the Egg Mixture In a large mixing bowl, whisk together the eggs and milk until well combined. Add in salt, pepper, and garlic powder to enhance the flavor of your casserole. The mixture should have a smooth consistency and appear light in color. This egg mixture will bind all the ingredients together and create a rich texture. Step 4: Combine with Spinach and Chicken Fold in the shredded chicken and fresh spinach to the egg mixture until everything is well incorporated. If you’re using frozen spinach, make sure it’s thoroughly thawed and drained to avoid excess moisture. The combination of chicken and spinach will ensure a deliciously nutritious filling for your casserole. Step 5: Pour and Soak Carefully pour the egg, chicken, and spinach mixture over the layer of bread in the baking dish. Press down gently to ensure the bread absorbs the liquid, allowing it to soak for 5-10 minutes. You should see the bread becoming slightly saturated, which contributes to a hearty and flavorful Chicken and Spinach Casserole. Step 6: Bake the Casserole Place the baking dish in the preheated oven and bake for approximately 25-30 minutes, or until the center is set and the top is golden brown. You’ll know it’s done when a toothpick inserted in the center comes out clean, indicating a perfectly cooked casserole that’s ready to serve. Step 7: Let Cool and Serve Once baked, remove the Chicken and Spinach Casserole from the oven and let it rest for about 5-10 minutes. This cooling period allows the casserole to firm up slightly, making it easier to slice. Serve warm, and enjoy the comforting flavors of this hearty dish that’s perfect for family meals or brunch gatherings!

Chicken and Spinach Casserole Recipe FAQs What type of bread should I use for the casserole? I recommend stale bread for the best results, as it absorbs moisture without getting soggy. If you don’t have stale bread, you can lightly toast fresh bread before using it. Gluten-free bread works well as a substitute if needed! How do I store leftover Chicken and Spinach Casserole? Store any leftover casserole covered in the fridge for up to 4 days. This keeps it fresh and allows for quick meals throughout the week. If you want to store it for longer, wrap it tightly and freeze it for up to 3 months. Can I freeze Chicken and Spinach Casserole? Absolutely! To freeze, make sure the casserole is completely cooled, then wrap it tightly in plastic wrap or place it in an airtight container. This helps to maintain its flavor and texture, preventing freezer burn. When ready to enjoy, thaw it in the fridge overnight before reheating. What should I do if my casserole is too watery? If the casserole turns out watery, it may be due to excess moisture from the spinach or not using stale bread. For next time, ensure any frozen spinach is well-drained and consider letting the casserole bake a bit longer to allow extra liquid to evaporate. If you find it mushy, it’s a sign to poke holes in the top during baking for steam to escape. Can I use other vegetables in this casserole? Yes, feel free to get creative! This Chicken and Spinach Casserole is highly customizable. Adding diced bell peppers, onions, or even mushrooms can elevate the flavor. Just make sure to pre-cook these veggies to reduce excess moisture and enhance their taste. Is this recipe suitable for pets? While ingredients like chicken and spinach are generally safe for pets, it’s important to avoid using excessive seasonings and cheese for them.
