Recipe FAQs

Whisk the flour and butter until smooth and gradually add milk and broth while whisking constantly to create a creamy, lump-free sauce.

What can I substitute for chicken broth?

Vegetable broth or water with a pinch of salt can be used as a substitute for a different flavor profile.

How can I add a spicy kick to this dish?

Include crushed red pepper flakes either in the breadcrumb topping or mixed into the sauce for subtle heat.
