Ingredients

Scale

Vegetables

  • 34 white turnips (about 700 grams or 1 1/2 pounds)

Dairy & Cheese

  • 1 cup (240 g) heavy cream
  • 2 cups (266 g) Gruyere or other easy melt cheese, freshly grated (divided)
  • 3 tablespoons Parmesan cheese (divided)

Spices & Seasonings

  • ⅛ teaspoon freshly grated nutmeg
  • ½ to 1 teaspoon white pepper
  • 1 to 2 teaspoons garlic powder (or 2 finely minced garlic cloves)
  • ½ teaspoon thyme
  • ½ teaspoon salt

Instructions

  1. Preheat Oven: Preheat your oven to 190 °C (375 °F) to prepare for baking the scalloped turnips.
  2. Slice Turnips: Peel the turnips and slice them into 1/8- to 1/4-inch thin slices using a sharp knife or mandoline to achieve even cooking.
  3. Mix Cream and Seasonings: In a bowl, combine heavy cream, freshly grated nutmeg, white pepper, garlic powder or minced garlic, thyme, salt, and about 1 1/2 cups of the grated Gruyere plus 2 tablespoons of Parmesan cheese to form the creamy cheese sauce.
  4. Layer Ingredients: Spread one quarter of the sliced turnips into the baking dish, then spoon over one quarter of the cheese and cream mixture. Repeat this layering process three more times until all turnips and sauce are used.
  5. Add Topping: Evenly spread the remaining grated Gruyere and Parmesan cheese over the top layer of the sauce.
  6. Bake Covered: Cover the dish with a lid or aluminum foil and bake in the preheated oven for 1 hour and 15 minutes, or until the turnips are fork tender.
  7. Broil to Finish: Remove the cover and place the dish under the broiler for 5 to 10 minutes until the cheese topping is golden brown and bubbly, forming a delicious crust.

Notes

  • You can substitute Gruyere with other easy-melt cheeses like Gouda, Raclette, or even mozzarella. Using block cheese grated at home is recommended for better melting and texture.
  • A 9″x3″ deep ceramic baking dish works well, and the four layers fill it about halfway, allowing room for bubbling. If using a larger dish, make three layers instead of four and start checking doneness after 1 hour.
