Boneless, skinless chicken breasts are my top choice for this recipe because they provide lean protein and cook evenly when cut into cubes.

The creamy element comes from a combination of Greek yogurt and light cream cheese, which provides protein while keeping the dish lighter than traditional heavy cream versions.

Add your cubed chicken and cook for 5-7 minutes, stirring occasionally, until the pieces are lightly golden on most sides they don’t need to be fully cooked at this stage. Stir in the spinach and artichoke hearts, cooking for 2-3 minutes until the spinach is wilted and any excess moisture has evaporated.

While the chicken cooks, whisk together the Greek yogurt, cream cheese, garlic powder, onion powder, salt, and pepper in a large mixing bowl until smooth and well combined. Remove the skillet from heat and fold the chicken mixture into the creamy sauce until everything is evenly coated.

FAQs About High-Protein Spinach Artichoke Chicken Casserole

Can I use frozen chicken for this High-Protein Spinach Artichoke Chicken Casserole?

Yes, but make sure to thaw it completely first and pat it very dry before cutting and cooking. Frozen chicken releases more water during cooking, which can make your casserole watery if not properly managed. Allow extra time for the initial browning step to ensure any excess moisture evaporates.

How do I fix an overcooked High-Protein Spinach Artichoke Chicken Casserole?

If your chicken becomes dry, try stirring in a little chicken broth, cream, or even additional Greek yogurt while the casserole is still warm. The residual heat will help incorporate the added moisture throughout the dish. For future batches, reduce cooking time by 5 minutes and check for doneness earlier.

Is this High-Protein Spinach Artichoke Chicken Casserole safe during pregnancy?

Yes, this recipe is perfectly safe for pregnant women when the chicken reaches the proper internal temperature of 165°F (74°C). The dairy products used are pasteurized, and all vegetables are cooked thoroughly. Always use a meat thermometer to ensure the chicken is fully cooked throughout.

Can I make this High-Protein Spinach Artichoke Chicken Casserole ahead of time?

Absolutely! Assemble the entire casserole up to 24 hours in advance, cover tightly with plastic wrap, and refrigerate. When ready to bake, remove from the refrigerator 30 minutes before cooking to take the chill off, then bake as directed, adding an extra 5-10 minutes if needed.

What’s the best way to reheat leftover High-Protein Spinach Artichoke Chicken Casserole?

For best results, reheat individual portions in the microwave with a splash of broth or milk to restore creaminess. For larger portions, cover with foil and reheat in a 325°F oven until warmed through, about 15-20 minutes. Avoid high heat, which can cause the dairy to separate.
