# Expert Tips:

01 -
  • The creamy sauce feels incredibly indulgent despite being low carb and keto friendly
  • Everything cooks in one pan then bakes in one dish meaning minimal cleanup
  • Leftovers reheat beautifully for lunch the next day if there are any
02 -
  • Do not overcook the chicken during the stovetop phase since it will continue cooking in the oven
  • The sauce will thicken as it bakes so it can seem slightly thin when you first combine everything
  • Let the casserole rest for 5 minutes after baking before serving to help it set
03 -
  • Rotisserie chicken works perfectly here and cuts prep time down to almost nothing
  • Swap broccoli for cauliflower spinach or asparagus based on what you have on hand
  • A pinch of smoked paprika in the sauce adds amazing depth without changing the carb count
