How to Make High-Protein Spinach and Artichoke Chicken Casserole Recipe
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This step ensures a perfectly hot oven so your casserole cooks evenly and the cheese melts just right, forming that irresistible golden crust.
Step 2: Prepare the Mixture
In a large mixing bowl, combine the shredded chicken, chopped artichoke hearts, thawed and drained spinach, Greek yogurt, cottage cheese, minced garlic, onion powder, salt, and pepper. Mix everything well so the flavors blend beautifully and every bite is packed with goodness.
Step 3: Assemble the Casserole
Grease a 9×13-inch baking dish to prevent sticking and make cleanup easier. Then, spread the prepared chicken mixture evenly over the bottom. This even layer will bake uniformly, ensuring every scoop delivers that perfect balance of ingredients.
Step 4: Add the Cheese Topping
Sprinkle shredded mozzarella and grated Parmesan evenly over the chicken mixture. These cheeses will melt beautifully, sealing in moisture while adding a rich, gooey texture and a gorgeous golden-brown finish.
Step 5: Bake to Perfection
Place your casserole in the preheated oven and bake for 25 to 30 minutes, until the edges are hot and bubbly and the cheese is melted and golden. This bakes the flavors together while giving the top that crave-worthy crust.
Step 6: Serve Warm and Enjoy
Once out of the oven, let your casserole rest for a few minutes. This helps it set and makes serving easier. For a fresh touch, sprinkle with chopped parsley before bringing it to the table.
How to Serve High-Protein Spinach and Artichoke Chicken Casserole Recipe

Garnishes
A handful of fresh parsley or a sprinkle of extra Parmesan right before serving adds a fresh, vibrant note that brightens the casserole beautifully. You can also add a few red pepper flakes if you like a slight kick.
Side Dishes
This dish pairs wonderfully with simple, crisp sides like a fresh garden salad or roasted vegetables to add contrasting textures. For a heartier meal, serve alongside quinoa or brown rice to soak up any extra cheesy goodness.
Creative Ways to Present
For a fun twist, serve the casserole in individual ramekins for a fancy presentation or spoon it over a bed of buttery mashed cauliflower to keep it low-carb and extra creamy. It’s versatile and ready to impress on any occasion.
Make Ahead and Storage
Storing Leftovers
Store any leftovers in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen overnight, making it a great next-day meal as well.
Freezing
If you want to prep in advance, this casserole freezes beautifully. Wrap tightly in foil or freeze in a sealed container for up to three months. Thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers in the oven at 350°F (175°C) until warmed through to retain that bubbly cheesy top. You can also microwave individual portions, though the texture is best when reheated gently in the oven.
FAQs
Can I use fresh spinach instead of frozen?
Absolutely! If you prefer fresh spinach, be sure to sauté it lightly and squeeze out excess moisture before adding to keep the casserole from becoming watery.
Is it possible to make this casserole dairy-free?
You can substitute the cheeses with your favorite dairy-free alternatives and use a dairy-free yogurt, but the texture will be slightly different. Experiment with flavors you love.
Can I substitute the chicken with turkey?
Yes, shredded cooked turkey works great in this recipe and offers a similar protein boost with a slightly different flavor profile.
How spicy is this casserole?
This recipe is mild and family-friendly, but you can easily add chili flakes or hot sauce to spice it up according to your preference.
Can I prepare this casserole ahead of time before baking?
Definitely! Assemble the casserole and cover it tightly with foil, then refrigerate for up to 24 hours before baking. Just add a few extra minutes to the cooking time if baking from cold.
