My Personal Experience
- The chicken stays incredibly satisfying:
Bite-sized chicken pieces distribute throughout the creamy spinach and artichoke mixture.
Every serving feels substantial without needing pasta, rice, or bread underneath. - The Greek yogurt sauce makes a big difference:
It gives the casserole a creamy, tangy texture while adding useful protein.
Mixing it with the other ingredients before baking helps create an even coating. - Spinach blends beautifully into the casserole:
Chopped spinach softens during baking and becomes part of the creamy filling.
It adds color and nutrients without overpowering the chicken and artichoke flavors. - The browned cheese topping is my favorite part:
A light layer of mozzarella develops a bubbly, golden finish in the oven.
Letting the casserole rest afterward makes the creamy center easier to serve.

Common Mistakes to Avoid
- Using watery spinach: Excess moisture can make the casserole loose, so squeeze thawed frozen spinach very well or drain fresh spinach thoroughly.
- Adding too much artichoke liquid: Drain and gently press the artichokes before chopping to prevent a watery filling.
- Overcooking the chicken: Cook the chicken just until done before assembling to avoid dry pieces after baking.
- Using very high heat with Greek yogurt: Excessive heat can cause yogurt-based sauces to separate, so bake at the recommended moderate temperature.
Required Equipment
- Large skillet — allows the chicken and spinach to cook evenly before assembling.
- Large mixing bowl — provides enough space to combine the creamy filling without spilling.
- 9×13-inch baking dish — spreads the casserole evenly for consistent baking.
- Sharp chef’s knife — makes it easy to cut the chicken and artichokes into uniform pieces.
- Measuring cups and spoons — keep the creamy sauce and seasonings balanced.
- Wooden spoon or silicone spatula — gently combines the ingredients without damaging the spinach or artichokes.
Storage Instructions
Allow the casserole to cool slightly, then transfer leftovers into airtight glass or food-safe containers. Refrigerate for up to 3–4 days.
For longer storage, portion the completely cooled casserole into freezer-safe containers and freeze for up to 2–3 months. Individual portions are especially convenient for high-protein meal prep.
To reheat from the refrigerator, microwave a serving for 1–2 minutes, stirring or checking halfway through, or place it in a covered oven-safe dish at 325°F (165°C) until heated through. For frozen portions, thaw overnight in the refrigerator before reheating for the best texture.

📝 Ingredients
Chicken & Vegetables
- 1½ lb boneless, skinless chicken breasts, cut into bite-sized pieces
- 5 oz fresh baby spinach, roughly chopped
- 1 can (14 oz) artichoke hearts, drained and chopped
- ½ medium yellow onion, finely diced
- 2 cloves garlic, minced
- 1 tbsp olive oil
Creamy Protein Sauce
- 1 cup plain nonfat Greek yogurt
- 4 oz light cream cheese, softened
- ½ cup shredded mozzarella cheese
- ¼ cup grated Parmesan cheese
- 1 tsp Italian seasoning
- ½ tsp garlic powder
- ½ tsp onion powder
- ¼ tsp black pepper
- ¼ tsp salt
- 1 tbsp lemon juice
Topping
- ½ cup shredded part-skim mozzarella cheese
- 1 tbsp grated Parmesan cheese
- ¼ tsp paprika, optional
Ingredient note: Use plain Greek yogurt rather than sweetened yogurt. For a lower-carb version, choose artichoke hearts packed in water and check the label for added ingredients.
Directions
- Preheat the oven:
Heat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
Preheating ensures the casserole begins cooking evenly as soon as it goes into the oven. - Cook the chicken:
Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the chicken pieces and cook for about 5–7 minutes, stirring occasionally.
The chicken should be lightly browned on the outside and cooked through; avoid overcooking because it will continue cooking in the oven. - Cook the aromatics and spinach:
Reduce the heat to medium and add the diced onion and minced garlic. Cook for 2–3 minutes until softened and fragrant.
Add the chopped spinach and cook for another 1–2 minutes, just until wilted. - Prepare the protein-rich sauce:
In a large bowl, combine Greek yogurt, softened cream cheese, ½ cup mozzarella, Parmesan, Italian seasoning, garlic powder, onion powder, black pepper, salt, and lemon juice.
Stir until creamy and evenly combined. - Add the vegetables and artichokes:
Fold the cooked spinach mixture and drained chopped artichokes into the sauce.
The mixture should look thick and creamy rather than watery. - Combine with chicken:
Add the cooked chicken to the creamy mixture and gently fold everything together.
Avoid vigorous stirring so the chicken pieces remain intact. - Assemble the casserole:
Transfer the mixture to the prepared baking dish and spread it into an even layer.
Sprinkle the remaining ½ cup mozzarella and 1 tablespoon Parmesan over the top. - Bake:
Bake uncovered at 375°F (190°C) for 20–25 minutes.
The casserole is ready when the center is hot, the edges are bubbling, and the cheese is melted and lightly golden. - Optional browning:
For a more golden top, switch to broil on high for 1–2 minutes, watching closely.
Stop when the cheese is bubbly and lightly browned. - Rest and serve:
Remove the casserole from the oven and let it rest for 5–10 minutes before serving.
This allows the creamy filling to settle and makes portions easier to scoop.
High-protein cooking tip: Use a strained Greek yogurt with a high protein content and lean chicken breast to maximize protein without needing large amounts of cheese.
