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 step is essential to create the perfect baking environment for the Spinach and Artichoke Chicken Casserole, ensuring it cooks evenly and thoroughly. While the oven warms up, you can prepare the chicken and other ingredients, keeping everything efficient for a smooth cooking experience.
Step 2: Season the Chicken
If desired, season the cubed boneless, skinless chicken breasts with kosher salt and let them rest at room temperature for about 20 minutes. This technique, known as dry-brining, enhances the flavor and moisture of the chicken. Once rested, the chicken will be ready to create a savory and satisfying foundation for your casserole.
Step 3: Prepare the Vegetables
Carefully squeeze excess moisture from the canned artichoke hearts and finely chop them. Set aside for later use. Next, take the thawed frozen chopped spinach and squeeze it thoroughly using a clean dish towel to remove any remaining moisture. This crucial step prevents your casserole from becoming watery, ensuring a rich and creamy texture.
Step 4: Cook the Chicken
In a large skillet, heat a tablespoon of avocado or olive oil over medium heat. Once hot, add the seasoned chicken pieces, cooking for 2-3 minutes on each side or until golden brown and cooked through. The chicken should be no longer pink in the center. Remove the cooked chicken from the pan and set it aside as you prepare the rest of the ingredients.
Step 5: Blend the Cheese Mixture
In a food processor, combine the cottage cheese, fresh garlic cloves, kosher salt, black pepper, and onion powder. Blend these ingredients until smooth and creamy. The creamy cottage cheese will not only enhance the flavor but will also add a satisfying richness to your Spinach and Artichoke Chicken Casserole, making it irresistibly delicious.
Step 6: Combine Ingredients
In a large baking dish, mix together the cooked chicken, chopped spinach, artichokes, and the blended cottage cheese mixture. Stir in about ⅔ of the shredded mozzarella and parmesan cheese, ensuring everything is evenly distributed. This harmonious blend of flavors will create a flavorful filling that’s sure to impress everyone at the dinner table.
Step 7: Bake the Casserole
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake the casserole for 20 minutes, allowing the flavors to meld and the dish to heat through. After 20 minutes, carefully uncover the dish, sprinkle the remaining mozzarella and parmesan cheese on top, and return it to the oven for an additional 10 minutes.
Step 8: Create the Golden Crust
To achieve a perfect golden crust on your Spinach and Artichoke Chicken Casserole, switch the oven to broil mode for 2-3 minutes. Keep a close eye on the dish during this time, as it can go from perfectly browned to burnt quickly. The bubbling, golden cheese will be a wonderful indication that your casserole is ready to be served!
Step 9: Let it Rest and Serve
Once broiling is complete, remove the casserole from the oven and let it rest for about 5 minutes. This will allow the flavors to settle and the casserole to firm up slightly. Serve warm, paired with a refreshing side salad or whole grains for a balanced meal that everyone will love!

Spinach and Artichoke Chicken Casserole Recipe FAQs
How do I choose ripe marinated artichoke hearts?
Absolutely! When selecting canned artichoke hearts, look for varieties that are firm and free from dark spots or excessive mushiness. Check the can for expiration dates and ensure they are well-drained before using to avoid adding excess moisture to your casserole.
What’s the best way to store leftovers?
Very! Store any leftover Spinach and Artichoke Chicken Casserole in an airtight container in the fridge for up to 3 days. When you’re ready to enjoy it again, reheat it until the cheese is melty and the casserole is heated through—this ensures that the flavors remain vibrant and delicious.
Can I freeze the casserole? If so, how?
You bet! To freeze your Spinach and Artichoke Chicken Casserole, let it cool completely after baking. Then, place it in an airtight container or wrap it tightly with plastic wrap and foil to prevent freezer burn. It can be stored for up to 2 months. For best results, thaw it overnight in the refrigerator before baking it at 350°F (175°C) for about 25–30 minutes, until heated throughout.
What should I do if my casserole becomes too watery?
Very common! If your casserole turns out watery, the likely culprit is excess moisture from the spinach or artichokes. To prevent this, make sure to squeeze out as much moisture as possible before adding them to the mix. If it happens, you can try adding breadcrumbs or starch (like cornstarch) to absorb excess liquid. Bake a little longer uncovered to help form a thicker consistency.
Is this casserole suitable for people with cheese allergies?
While this recipe does use cheese for its creamy texture, you can modify it to fit dietary considerations. Try switching to a dairy-free cheese alternative or even Greek yogurt for creaminess. Always check labels to ensure there’s no hidden dairy for those with allergies. Enjoying the flavors is possible without compromising health!
Can I use fresh spinach instead of frozen?
Absolutely! Fresh spinach can be a delightful substitute. If you go this route, wash and sauté it briefly to reduce moisture before adding it to the casserole. You’ll want to squeeze any excess liquid from the cooked spinach so that your casserole has that creamy consistency without being mushy.
