Tips & Variations

  • Make sure to squeeze out as much water as possible from the spinach to avoid a watery gratin.
  • For a richer flavor, add a handful of shredded cheese such as cheddar or Gruyère before baking.
  • Use fresh garlic for a stronger taste or garlic powder if preferred.
  • Swap fried onions with breadcrumbs for a different crunchy topping.

Storage

Store leftover spinach gratin in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through to maintain its creamy texture.
