Frequently Asked Questions

Can I use fresh broccoli instead of frozen?

Yes, fresh broccoli can be used! Just make sure to steam it lightly before mixing it into the casserole. This will help maintain its vibrant color and texture. Adjust the cooking time slightly if needed, as fresh broccoli might cook faster than frozen.

How can I make this dish gluten-free?

To make this casserole gluten-free, simply substitute regular bread crumbs with gluten-free bread crumbs. You can also crush gluten-free crackers or use ground almonds as a topping. This ensures everyone can enjoy the dish without compromising on taste or texture.

Can I prepare this casserole in advance?

Absolutely! You can prepare the casserole up to the point of baking, cover it tightly, and refrigerate it for up to 24 hours. When you're ready to bake, just add a few extra minutes to the cooking time to ensure it's heated through. This makes it convenient for meal prep or potlucks.
