Tips
Blanching broccoli briefly preserves color and texture; ice bath stops cooking immediately for vibrant green florets in the finished dish.
Stir mushroom sauce constantly after adding flour to prevent lumps; thickness should coat the back of a spoon.
Butter panko topping right before baking so crumbs stay separate and crisp rather than clumping.
Good to Know
Cover and refrigerate up to 3 days. Reheat covered at 325 F until warmed through, about 25 to 30 minutes.
Assemble casserole completely, cover, and refrigerate up to 12 hours before baking. Add 10 to 15 minutes to bake time if starting from cold.
Serve directly from casserole dish family-style. Pairs well with green salad dressed in vinaigrette or roasted Brussels sprouts.
Common Mistakes
Skip pre-blanching broccoli to avoid mushy florets in final dish.
Add flour without coating vegetables evenly to avoid lumpy sauce.
Don't stir panko butter mixture to avoid soggy clumpy topping.

FAQ
Can I make this ahead?

What if my sauce is too thick or thin?
Thick sauce: whisk in more broth 1 tablespoon at a time. Thin sauce: simmer uncovered 2 to 3 minutes longer, or whisk in 1/2 teaspoon cornstarch mixed with 1 tablespoon cold water.
Can I freeze this casserole?
Freeze unbaked casserole up to 1 month tightly wrapped. Thaw in refrigerator overnight, then bake at 325 F for 45 to 50 minutes covered, then 15 minutes uncovered.
