Equipment

  • Mandoline
  • 2-quart casserole dish
  • Baking Sheet

Ingredients
  

  • 1.25 pounds Russet Potatoes unpeeled and thinly sliced (about 3 medium-large)
  • 1.5 cups Heavy Cream
  • 0.25 cup Fresh Chives minced
  • 1 cup Blue Cheese crumbled (use a milder variety if preferred)
  • Pinch Kosher Salt
  • Pinch Ground Black Pepper

Instructions
 

  • Get Ready to Bake! Preheat your oven to 375°F (190°C).
  • Slice Your Spuds: Using a mandoline or a sharp knife, carefully slice your potatoes into thin ¼-inch rounds. You can leave the skin on for extra nutrients and ease, or peel them if you prefer.
  • Prepare the Dish: Lightly spray a 2-quart casserole dish with non-stick cooking spray, or butter it generously.
  • First Layer: Arrange one-third of the potato slices evenly at the bottom of the dish. Sprinkle lightly with salt and pepper, then scatter one-third of the minced chives and one-third of the crumbled blue cheese over the potatoes.
  • Second Layer: Repeat the process! Add another third of the potato slices, season with salt and pepper, and top with another third of the chives and blue cheese.
  • Final Layer & Cream: Place the last third of potato slices, season again with salt and pepper, and finish with the remaining blue cheese. Carefully pour the heavy cream evenly over everything, pressing down gently to make sure the potatoes are submerged.
  • Bake to Golden Perfection: Place your casserole dish on a baking sheet (lined with foil or parchment for easy cleanup). Bake for about 1 hour, or until the top is golden brown, bubbly, and the potatoes are wonderfully tender when pierced with a fork.
  • Garnish & Serve: Take the dish out of the oven. Sprinkle the last bit of fresh chives on top and serve this delicious gratin immediately!
