Spinach and Artichoke Chicken Casserole Ingredients
For the Casserole
- Cottage Cheese (16 oz) – Boosts protein content and adds creaminess; use 4% fat for the best texture.
- Garlic cloves (2) – Fresh garlic adds depth of flavor; it’s recommended for the best taste.
- Kosher salt (½ tsp) – Enhances overall flavors; feel free to adjust to your personal taste.
- Black pepper (¼ tsp) – Provides essential seasoning; freshly ground is always preferred.

- Avocado oil or olive oil (1 tsp) – Used for cooking the chicken and adding healthy fats; you can substitute coconut oil if preferred.

- Low-moisture, part-skim mozzarella cheese (½ cup) – Provides that gooey, cheesy texture; any melty cheese can work if you prefer something different.
- Finely grated parmesan cheese (⅔ cup) – Adds rich, nutty flavor; nutritional yeast can serve as a vegan substitute.
- Canned artichoke hearts (1 can, 16 oz) – They bring a tangy kick and essential flavor; opt for artichokes packed in water to control acidity.

Step‑by‑Step Instructions for Spinach and Artichoke Chicken Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). If you have time, optionally season the chicken breast pieces with kosher salt and let them sit for about 20 minutes to enhance flavor. This simple step elevates your High-Protein Spinach and Artichoke Chicken Casserole, creating a more flavorful base.
Step 2: Prep the Artichokes
While the chicken is brining, open the can of artichoke hearts, draining and squeezing out any excess liquid. Finely chop them and set aside. This will help integrate their tangy flavor into the casserole, making it rich and satisfying.
Step 3: Handle the Spinach
Next, take your frozen chopped spinach and place it in a clean kitchen towel to squeeze out excess moisture. This is crucial to avoid a watery casserole. Properly dried spinach will ensure that your Spinach and Artichoke Chicken Casserole achieves the perfect creamy consistency.
Step 4: Cook the Chicken
In a large skillet, heat 1 teaspoon of avocado or olive oil over medium heat. Add the bite-sized chicken pieces and season them with black pepper. Cook for about 5-6 minutes, stirring occasionally, until the chicken is nearly cooked through. Once ready, remove the chicken from the skillet and set aside.
Step 5: Blend the Base
In a food processor, combine the cottage cheese, garlic cloves, kosher salt, black pepper, and onion powder. Blend these ingredients until smooth and creamy. This mixture serves as the flavorful base of your casserole, ensuring each bite is rich and delicious.
Step 6: Mix the Casserole
In a large baking dish, combine the cooked chicken, squeezed spinach, chopped artichokes, and the creamy cottage cheese blend. Fold in ⅔ of the mozzarella and parmesan cheese, mixing well to ensure everything is evenly incorporated. This step is where your Spinach and Artichoke Chicken Casserole starts to take shape.
Step 7: Bake Covered
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 20 minutes, allowing the flavors to meld and the casserole to heat through. The aroma wafting through your kitchen is sure to be irresistible at this point.
Step 8: Add Toppings and Finish Baking
After 20 minutes, carefully uncover your casserole and sprinkle the remaining mozzarella and parmesan cheese evenly on top. Return it to the oven and bake for an additional 10 minutes, or until the top is golden and bubbly. If desired, broil for a minute or two to achieve that perfect crispy crust.
Step 9: Rest and Serve
Once out of the oven, let your Spinach and Artichoke Chicken Casserole rest for a few minutes to set before serving. This resting period helps the casserole maintain its shape when spooned onto plates, allowing for an appealing presentation at your family meal.
