Step‑by‑Step Instructions for Spinach and Artichoke Chicken Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This crucial first step ensures the casserole cooks evenly and achieves that golden, bubbly finish we all crave. Preheating also helps to maintain the creamy texture of the spinach and artichoke filling as it bakes.
Step 2: Prepare the Chicken
If desired, season the cubed boneless, skinless chicken breast generously with kosher salt. Let the chicken rest at room temperature for about 20 minutes. This optional step enhances the flavor and moisture of the chicken, setting a solid foundation for your Spinach and Artichoke Chicken Casserole.
Step 3: Chop the Artichokes
Drain the canned artichoke hearts and finely chop them after pressing out any excess liquid. This prevents sogginess in your casserole and allows the rich artichoke flavor to shine through. Set the chopped artichokes aside while you prepare the other components.
Step 4: Drain the Spinach
Take the frozen chopped spinach and thaw it completely. Once thawed, place the spinach in a clean kitchen towel and squeeze out as much excess water as possible. This is key to achieving a thick, satisfying casserole without too much moisture, making the spinach a perfect complement to the artichoke.
Step 5: Cook the Chicken
In a large skillet, heat a tablespoon of avocado oil over medium heat. Add the seasoned cubed chicken to the pan, cooking for about 4-6 minutes, or until the chicken is nearly cooked through but still slightly pink. This will ensure that your chicken remains tender once baked and fully incorporated into the Spinach and Artichoke Chicken Casserole.
Step 6: Blend the Cheese Mixture
In a food processor, combine the cottage cheese, minced garlic, kosher salt, black pepper, and onion powder. Blend until the mixture is smooth and creamy, about 30-60 seconds. This flavorful base will create the rich, cheesy sauce that brings your casserole together.
Step 7: Combine the Ingredients
In a large baking dish, mix the cooked chicken, squeezed spinach, chopped artichokes, and the blended cheese mixture together. Then, fold in two-thirds of the low-moisture mozzarella and grated Parmesan cheese. Stir until everything is well combined, ensuring every bite of the casserole is packed with flavor.
Step 8: Bake the Casserole
Cover the mixed casserole dish tightly with aluminum foil and transfer it to the preheated oven. Bake for 20 minutes, allowing the flavors to meld together. This step traps steam, making for a moist and delicious Spinach and Artichoke Chicken Casserole.
Step 9: Add the Final Touches
After the initial bake, carefully remove the foil and sprinkle the remaining mozzarella and Parmesan cheese evenly on top. This will create that desirable melty cheese layer. Return the casserole to the oven and bake uncovered for an additional 10 minutes, or until the cheese is bubbly and golden.
Step 10: Broil for a Golden Finish
If desired, switch your oven to broil and cook for an additional 2-3 minutes. Keep a close eye on it to prevent burning. This final touch adds that perfect golden crust to your Spinach and Artichoke Chicken Casserole, ensuring it’s as appealing as it is delicious.
