Ingredients
Chicken
1 lb boneless, skinless chicken breasts, cut into 1-inch cubes (or whole chicken breasts)
Spinach
2 cups fresh spinach, chopped (packed)
Dairy
1/2 cup sour cream
1/2 cup mayonnaise (or plain Greek yogurt)
3/4 cup grated Parmesan cheese
Aromatics & Oil
1 tbsp olive oil
4 cloves garlic, minced
Seasonings
1 tsp garlic powder
1 tsp salt
1/4 tsp black pepper
1/2 tsp paprika
Instructions
Preheat the oven
Preheat your oven to 375°F (190°C) and lightly grease a medium baking dish with olive oil or nonstick spray.
Prepare the chicken
Pat the chicken dry with paper towels. If using whole breasts, place them evenly in the baking dish. If using cubed chicken, spread the pieces in a single layer.
Sauté the garlic
Heat 1 tablespoon olive oil in a small pan over medium heat. Add the minced garlic and cook for about 30–45 seconds until fragrant. Remove from heat.
Make the creamy mixture
In a mixing bowl, combine sour cream, mayonnaise (or Greek yogurt), grated Parmesan cheese, garlic powder, salt, black pepper, and paprika.
Add garlic and spinach
Stir the sautéed garlic and chopped spinach into the creamy mixture until well combined.
Assemble the dish
Spread the creamy spinach mixture evenly over the chicken in the baking dish, covering all pieces.
Add extra Parmesan (optional)
For a richer flavor, sprinkle an additional 2–3 tablespoons of Parmesan cheese over the top.
Bake the chicken
Place the dish in the preheated oven and bake for 30–35 minutes, or until the chicken is cooked through and the top is lightly golden.
Check doneness
Ensure the internal temperature of the chicken reaches 165°F (74°C).
Rest and serve
Let the dish rest for 5 minutes before serving. Garnish with fresh parsley if desired and serve warm.
Tips
Use room-temperature ingredients so the creamy mixture blends smoothly.
Avoid overcooking the garlic; burnt garlic can turn bitter.
Fresh spinach works best, but frozen spinach can be used if squeezed dry.
Cube the chicken evenly to ensure consistent cooking.
Use freshly grated Parmesan for the best flavor and texture.
Let the dish rest after baking so the sauce thickens slightly.
Add a breadcrumb topping if you want a crisp crust.
Use a ceramic or glass baking dish for even heat distribution.
Marinate the chicken briefly with salt and garlic powder for extra flavor.
Broil for 2–3 minutes at the end if you want a golden top.
