Frequently Asked Questions

Can I use frozen turkey fillets for this recipe?

Yes, you can use frozen turkey fillets, but it's best to thaw them first. This ensures even cooking and helps the flavors meld properly. If using frozen, increase the cooking time slightly, monitoring the turkey to ensure it's fully cooked to 165°F.

What can I substitute for tomatoes if I don’t have canned ones?

If you don't have canned tomatoes, you can use fresh tomatoes, about 2-3 medium ones, chopped. Alternatively, tomato sauce can work, but reduce the liquid in the recipe slightly to maintain the desired consistency.

Is there a vegetarian option for this casserole?

Absolutely! You can replace the turkey with a plant-based protein like tofu, tempeh, or even chickpeas. Just make sure to adjust the cooking time accordingly, as plant-based proteins may require less time to cook through.
