This casserole was a hit with my family, especially after a chilly weekday when comfort food was needed most. It's fun to let kids sprinkle the cheesy topping before baking.

Serving Suggestions

Enjoy with a crisp Chardonnay or a light green salad to balance the rich flavors. Garlic bread makes a tasty side.

Recipe FAQs

Can I use frozen broccoli instead of fresh?

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

How can I make the topping extra crispy?

Toss panko breadcrumbs with olive oil before sprinkling on top to create a golden, crunchy crust when baked.

Is there a substitute for Dijon mustard in the sauce?

Yellow mustard or a small amount of prepared horseradish can be used, but Dijon provides a subtle tang that complements the cheddar.

Can I prepare this ahead of time?

You can assemble the casserole and refrigerate it for up to 24 hours before baking to save time on the day of serving.

What sides pair well with this dish?

A fresh green salad or steamed vegetables balance the richness nicely, and a light white wine complements the flavors.
