Tips from the Betty Crocker Kitchens

  • tip 1
    Crimini or baby bella mushrooms have a rich mushroom flavor; if you want to dial back the mushrooms, use sliced button mushrooms instead.
  • tip 2
    This recipe uses thyme in the topping; you can use any fresh herb that you want. For instance, basil, tarragon or rosemary would also make good choices.
