Recipe FAQ

How do I ensure the chicken stays tender?

Partially cooking the chicken cubes in a skillet before baking helps maintain moisture and tenderness throughout the dish.

Can I use frozen broccoli instead of fresh?

Yes, just thaw and drain frozen broccoli florets before mixing to avoid excess moisture in the casserole.

What gives the topping its crispy texture?

Combining melted butter with breadcrumbs and a sprinkling of cheddar creates a golden, crunchy crust during baking.

Are there alternatives to sour cream in the sauce?

Greek yogurt can be substituted for sour cream to add a lighter, tangy creaminess without changing the flavor profile much.

Which herbs complement this dish well?

Dried thyme is used for an aromatic note, but fresh thyme or a pinch of smoked paprika can enhance the flavor further.
