  • 4 tbsp cheddar cheese (grated )
  • 1½ tbsp Parmesan cheese (grated )
  • Salt and pepper to taste

Instructions
 

Step 1: Prepare Potatoes

  • Peel potatoes and trim off any rough or bruised spots
  • Cut potatoes into thin slices (⅛ to ¼ inch thick)

Step 2: Arrange in Dish

  • Place sliced potatoes in a baking dish
  • Fan them slightly for even layering

Step 3: Season and Layer

  • Sprinkle with salt and pepper
  • Drizzle with melted butter

Step 4: Bake the Gratin

  • Bake at 425°F (220°C) for about 50 minutes

Step 5: Add Cheese and Finish Baking

  • Sprinkle top with cheddar and Parmesan
  • Bake for an additional 10–15 minutes, until cheese is melted and golden
  • Check doneness with a fork—potatoes should be tender

Tips

  • Add a splash of cream or milk between layers for a richer gratin.
  • Swap cheddar for Gruyère or Swiss for deeper flavor.
  • Add thin‐sliced onions between potato layers for sweetness.
  • Top with breadcrumbs for a crispier crust.
  • Mix in garlic powder or minced garlic for extra aroma.
