When it comes to comfort food that also supports a healthy lifestyle, this High Protein Spinach and Artichoke Chicken Casserole is one of my absolute favorites. Inspired by the classic spinach and artichoke dip, this recipe transforms those creamy, cheesy flavors into a satisfying, protein-rich main dish that is perfect for weeknight dinners or meal prep.
I love how this casserole strikes the perfect balance between indulgence and nutrition. The tender chicken provides a strong protein base, while spinach and artichokes add depth, texture, and essential nutrients. Combined with a creamy, cheesy sauce, this dish feels hearty and comforting without being overly heavy.

Ingredients
- 2 cups cooked chicken breast (shredded or diced)

- 2 cups fresh spinach (or 1 cup frozen, thawed and well-drained)
- 1 cup plain Greek yogurt
- 1/2 cup cream cheese (softened)
- 1/2 cup mozzarella cheese (grated)
- 1/4 cup Parmesan cheese (grated)
- 2 cloves garlic (minced)

- 1/2 teaspoon red chili flakes (optional)

Step-by-Step Instructions
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). This ensures even cooking from the start.
Lightly grease a medium baking dish with olive oil or butter. Make sure to coat the bottom and sides to prevent sticking and to help with easy serving later.
Step 2: Cook the Spinach
Place a pan over medium heat and add 1 tablespoon of olive oil. Once heated, add the minced garlic and sauté for about 30 seconds until fragrant.
Add the fresh spinach and cook for 2–3 minutes, stirring gently, until it wilts completely. If using frozen spinach, ensure it is fully thawed and squeezed dry before adding it to the pan.
Remove from heat and let it cool slightly.
Step 3: Prepare the Creamy Base
In a large mixing bowl, combine the Greek yogurt and softened cream cheese. Mix thoroughly until smooth and lump-free.
Add onion powder, salt, black pepper, and red chili flakes. Stir well so the seasoning is evenly incorporated into the mixture.
Step 4: Prepare Chicken and Artichokes
Shred or dice your cooked chicken into bite-sized pieces.
Drain the artichoke hearts thoroughly and chop them into smaller pieces. Proper draining is important to prevent excess moisture in the casserole.
Step 5: Combine All Ingredients
Add the cooked chicken, sautéed spinach, and chopped artichokes into the creamy mixture.
Mix gently but thoroughly until all ingredients are evenly coated. This step ensures every bite is full of flavor.
Step 6: Add Cheese to the Mixture
Add half of the mozzarella cheese and half of the Parmesan cheese into the mixture.
Stir until the cheese is well distributed. This helps create a creamy, cheesy interior texture.
Step 7: Assemble the Casserole
Transfer the mixture into your prepared baking dish. Spread it evenly using a spatula.
Sprinkle the remaining mozzarella and Parmesan cheese over the top. This will create a golden, bubbly crust during baking.
Step 8: Bake
Place the dish in the oven and bake for 25–30 minutes.
The casserole is ready when:
- The edges are bubbling
- The top is golden brown
- The center is fully heated
For a slightly crispy top, broil for an additional 2–3 minutes at the end.
Step 9: Rest Before Serving
Remove the casserole from the oven and allow it to rest for 5 minutes.
This helps the casserole firm up and makes it easier to serve while enhancing the overall texture.
Step 10: Serve
Serve warm as a main dish or alongside:
- Steamed vegetables
- Rice or cauliflower rice
- Fresh salad
