Notes

  • If you want a complete vegetarian version of gratin, skip the egg and add ¼ cup of milk. 
  • Roasting cauliflower and potato not only adds flavor but also keeps the gartin from getting watery. 
  • Instead of cauliflower, you can even use broccoli or combine the two for more flavor and color. 
  • Feel free to add vegetables like Brussels sprouts, spinach, and zucchini. 
  • Leftovers can be stored in a refrigerator in an airtight container for up to 4 days. 
  • Instead of goat cheese, you can even use cream cheese in the recipe. 
  • Potato cauliflower gratin can be made ahead of time and baked just before serving. 
  • Love a cheesy and creamy gratin; add an additional ½ cup of sharp cheddar cheese or mozzarella cheese and ½ cup of cream if desired. 
  • If you are a meat lover, then add diced ham, cooked bacon, or chicken to the recipe. 
  • A pinch of nutmeg and ½ teaspoon of dry mustard powder will enhance the flavor of the dish. 
  • You can top the gratin with breadcrumbs for the crispy topping.
