You can also use vegetable broth instead of chicken broth for a vegetarian version. For a gluten-free alternative, swap the flour and bread crumbs with gluten-free varieties.

Frequently Asked Questions
Can I prepare the casserole ahead of time?
Yes, you can prepare the casserole a day in advance. Simply assemble it, cover it tightly with plastic wrap, and refrigerate. When you're ready to bake, remove the wrap and bake as directed. You may need to increase the baking time slightly if baking straight from the fridge.
What if I don't have dry sherry?
If you don't have dry sherry, you can substitute it with white wine or even apple cider vinegar mixed with a little water. This will still provide a nice acidity and depth of flavor. Just ensure that whatever substitute you use is dry and not sweet.
Can I make this dish vegetarian?
Absolutely! To make it vegetarian, simply replace the chicken broth with vegetable broth. The rest of the ingredients are already vegetarian-friendly. This adjustment will keep the flavor profile intact while catering to vegetarian diets.
