Frequently Asked Questions
Can I use frozen flounder fillets for this recipe?
Yes, you can use frozen flounder fillets. Just ensure they are fully thawed and patted dry before adding them to the casserole to avoid excess moisture in the dish. This will help maintain the right texture.
What can I substitute for the dill weed?
If you don't have dill weed, you can use dried thyme or parsley as a substitute. Both herbs offer a different flavor but will still complement the fish nicely. Fresh herbs can also be used for a more vibrant taste.
How can I make this recipe spicier?
To add some heat, consider incorporating a pinch of cayenne pepper or red pepper flakes into the sauce. You can also serve the casserole with a side of hot sauce for those who enjoy an extra kick.
