Frequently Asked Questions

Can I use frozen spinach instead of fresh?

While frozen spinach can be used, fresh spinach is recommended for the best texture and flavor. If using frozen, ensure it’s thoroughly drained to avoid a soggy mixture.

How do I know when the chicken is fully cooked?

The chicken is properly cooked when it reaches an internal temperature of 165°F (74°C). Using a meat thermometer inserted into the thickest part of the breast will provide an accurate reading.

Can this dish be prepared ahead of time?

Yes, you can prep the individual components ahead of time and assemble just before baking. The dish can be stored in the fridge for up to 12 hours after assembly; bake as directed when ready.

What can I substitute for Greek yogurt?

For a non-dairy alternative, coconut or almond-based yogurt works well. For a thicker texture without dairy, you can use sour cream.

Is it possible to make this recipe gluten-free?

Yes, just ensure all herbs and any pre-packaged items you use (like broth or seasoning) are gluten-free. Fresh ingredients and spices typically contain no gluten.
