  • Yield: 5 minutes before serving 1x

Description

A rich and creamy cheesy root vegetable gratin featuring layers of tender potatoes, carrots, and parsnips baked in a luxurious cream sauce with sharp cheddar and Gruyère cheese.


Ingredients

Scale
  • 2 cups potatoes, thinly sliced
  • 1 cup carrots, thinly sliced
  • 1 cup parsnips, thinly sliced
  • 1 cup heavy cream
  • 1 cup sharp cheddar cheese, shredded
  • 1 cup Gruyère cheese, shredded
  • 3 cloves garlic, minced
  • 2 tbsp unsalted butter
  • Salt and pepper to taste

Instructions

  • Prep and Preheat: Preheat oven to 375°F (190°C) and grease baking dish with butter thoroughly
  • Slice Vegetables: Peel and slice root vegetables into 1/8-inch thick rounds using sharp knife or mandoline
  • Prepare Cream Base: Warm heavy cream with minced garlic in saucepan over low heat; season with salt and pepper
  • First Layer: Layer half the root vegetables in baking dish, pour half cream mixture, sprinkle half cheese blend
  • Second Layer: Repeat layering with remaining vegetables, cream mixture, and cheese for complete coverage
  • Initial Bake: Cover with foil and bake 45 minutes until vegetables are fork-tender
  • Final Browning: Remove foil and bake additional 15-20 minutes until bubbly and golden brown on top
  • Rest and Serve: Cool for 5 minutes before serving to allow layers to set properly

Notes

  • Use a mandoline slicer for perfectly uniform vegetable thickness, ensuring even cooking throughout all layers
  • Pat vegetables dry with paper towels after slicing to prevent excess moisture from making the gratin watery
  • Mix the two cheeses together before layering for more even distribution and better melting consistency
  • Test doneness by inserting a knife through center – it should slide through easily without resistance
