Pro Tips for the Perfect Brussels Sprouts Casserole:

  1. Even Sizing: Cut Brussels sprouts into uniform halves to ensure consistent cooking throughout the dish.
  2. Proper Draining: Remove excess moisture from the sprouts after cooking to prevent a watery casserole.
  3. Cheese Selection: Use freshly grated cheese rather than pre-shredded for superior melting and flavor.
  4. Temperature Control: Let the casserole rest for 5 minutes before serving to allow the sauce to thicken.
  5. Make-Ahead Option: Prepare the casserole up to 24 hours in advance and bake just before serving.
