Finnish Beetroot and Blue Cheese Gratin

This Finnish Beetroot and Blue Cheese Gratin is inspired by traditional Finnish oven-baked dishes, where earthy beetroot, cream, and simple seasoning come together in comforting layers. Grated beetroot, leek, and garlic are baked with blue cheese in a lightly sweetened cream sauce, creating a dish that feels both rustic and refined. Perfect as a vegetarian main or a side dish, this gratin reflects the heart of Finnish home cooking.

Equipment

  • Box grater or food processor with grating blade
  • Sharp knife
  • Cutting board
  • Two mixing bowls
  • Ovenproof baking dish
  • Measuring cups and spoons

Ingredients
  

  • 1 kg (2.2 lb) beetroot peeled and coarsely grated
  • 1 leek thinly sliced
  • 1 garlic clove finely grated or very finely chopped
  • 1-2 tsp black pepper coarsely ground
  • 2 tsp dried thyme
  • 2 tsp maple syrup
  • 150-170 g (5-6 oz) blue cheese (Finnish)
  • 1 tsp salt
  • 3 dl (1¼ cups) heavy cream
  • 2 dl (¾–1 cup) grated cheese for topping
  • 1 tbsp canola oil for creasing the oven dish

Instructions
 

Prepare the vegetables

  • Preheat the oven to 175°C / 350°F.
  • Peel and coarsely grate the beetroot. Thinly slice the leek and finely grate or chop the garlic.
  • Place all the vegetables in a large bowl and mix gently.

Prepare the cream mixture

  • In a separate bowl, combine the heavy cream, salt, black pepper, dried thyme, and maple syrup. Whisk thoroughly until well combined.

Assemble the gratin

  • Lightly oil an ovenproof baking dish.
  • Add a layer of the vegetable mixture, then sprinkle with some of the crumbled blue cheese. Continue layering the vegetables and blue cheese, finishing with a layer of vegetables on top.

Finish the dish

  • Pour the seasoned cream mixture evenly over the vegetables.
  • Sprinkle the grated cheese evenly over the top.

Bake

  • Bake uncovered for 1 hour to 1 hour 10 minutes, until the beetroot is fully tender and the gratin is bubbling.
  • If the top begins to brown too quickly, loosely cover the dish with foil or a lid for the remaining baking time.

Rest and serve

  • Let the gratin rest for about 10 minutes before serving to allow it to set slightly.

Notes

This gratin works well as a vegetarian main or a side dish with a crisp green salad.
A mild or medium blue cheese gives a balanced flavor, while a stronger blue cheese creates a bolder dish.
Covering the gratin during baking helps prevent over-browning while ensuring the beetroot cooks through evenly.
Leftovers keep well and reheat gently in the oven.
