Ingredients

Scale

Vegetables

  • 2 medium beets, peeled and thinly sliced
  • 1 large sweet potato, peeled and thinly sliced
  • 1 small red onion, thinly sliced
  • 2 tbsp olive oil
  • ¾ tsp salt
  • ½ tsp black pepper
  • ½ tsp dried thyme or oregano

Cheese & Topping

  • ¾ cup crumbled feta cheese
  • ¼ cup walnuts, toasted and chopped
  • ¼ cup grated Parmesan cheese (optional for extra richness)
  • 1 clove garlic, minced

Instructions

  1. Preheat oven: Preheat your oven to 200°C (400°F) and lightly grease a baking dish to prevent sticking.
  2. Prepare the vegetables: In a large bowl, toss together the sliced beets, sweet potatoes, and red onion with olive oil, salt, black pepper, and your choice of dried thyme or oregano until all slices are well coated with the seasoning.
  3. Assemble the gratin: Arrange the vegetables in the greased dish, layering them by alternating beets, sweet potatoes, and onions. Between each layer, sprinkle minced garlic and crumbled feta cheese evenly. Continue layering until all ingredients are used, finishing with a vegetable layer on top. Finally, scatter the toasted chopped walnuts and optionally the grated Parmesan cheese evenly over the surface.
  4. Bake: Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes. Then remove the foil and continue baking for an additional 15 to 20 minutes, or until the vegetables are fully tender and the topping is golden brown.
  5. Serve: Allow the gratin to rest for 5 minutes before slicing. Serve warm as a savory side dish or a wholesome vegetarian main course.

Notes

  • For extra richness, sprinkle Parmesan cheese on top before baking.
  • Walnuts can be swapped with pine nuts or pecans based on preference.
  • Use dried oregano or thyme depending on your flavor preference.
  • Allow gratin to rest after baking to settle the layers and make slicing easier.
  • This dish pairs well with roasted meats or a fresh green salad for a balanced meal.
  • Optional drizzle of balsamic reduction or extra olive oil before serving adds a nice touch.
