Equipment

Ingredients
  

  • 2 lbs turnips (opt for medium to smaller sized turnips)
  • 4 tbsp unsalted butter diced and divided
  • 1 tsp pink salt
  • 1/2 tsp cracked black pepper
  • 1 tsp organic garlic powder
  • 8 ounces sharp white cheddar cheese shredded
  • 1 1/4 cup heavy cream
  • 1 tsp fresh thyme leaves

Instructions
 

  • Preheat oven to 375 degrees F.
  • Peel the turnips and slice them 1/8 inch thick with a sharp knife or a mandolin.
  • Grease the baking dish with 1 tablespoon of butter.
  • Combine the salt, pepper, and garlic powder in a small bowl.
  • Spread 1/3 of the turnips in the bottom of the dish.
  • Top with 1/3 each of the cream, cheese, salt mixture, butter, and thyme.
  • Repeat with the next 2 layers, finishing with the last 1/3 of the cheese.
  • Cover with foil and bake for 45 minutes.
  • Remove foil and continue to bake for an additional 20 minutes or until the turnips are tender and the cream is absorbed, and the top is turning golden brown.
  • If the top is not golden brown enough, you can place the gratin under the broiler for a minute or two. DO NOT walk away, it will happen quickly.
  • Allow the gratin to rest for 10 minutes before serving.
