Questions & Answers
Q: Can I use chicken thighs instead of breasts?
Yes! Chicken thighs work great and often stay more tender. Adjust cooking time slightly as thighs may take longer to cook through.
Q: How do I prevent the zucchini from getting mushy?
Cut zucchini into thicker rounds (about 1/4 inch) and salt them beforehand to draw out excess moisture. Also, avoid overcooking.
Q: Can I make this dish ahead of time?
You can prep all ingredients up to 24 hours in advance and store them separately in the refrigerator. Assemble and bake when ready to serve.
Q: Is this recipe keto-friendly?
Yes, if you omit the breadcrumbs. The dish is naturally low in carbs and high in protein.
Q: Can I add other vegetables?
Absolutely! Yellow squash, mushrooms, or eggplant work well. Just ensure they have similar cooking times or adjust accordingly.
