Recipe FAQs

Can I use frozen broccoli instead of fresh?

Yes, thaw and drain frozen broccoli before using to avoid excess moisture in the dish.

What other proteins can I substitute for chicken?

Rotisserie chicken is a great shortcut, or cooked turkey works well too for a similar texture.

How do I get a crispy topping?

Mix panko breadcrumbs with olive oil and sprinkle over the cheese topping before baking to achieve a golden, crunchy crust.

Can this dish be made spicier?

Adding crushed red pepper flakes to the breadcrumb topping adds a subtle kick if desired.

Is it okay to make this ahead of time?

Prepare the casserole up to step 8, cover, and refrigerate; bake when ready, adding extra time if chilled.
