 Time

  • Prep: 20 minutes
  • Bake: 50–60 minutes
  • Total: 1 hour 10–20 minutes
  • Servings: 6

 Ingredients

  • 2 medium beets, peeled and thinly sliced
  • 2 medium sweet potatoes, peeled and thinly sliced
  • 1 cup crumbled feta cheese
  • ½ cup chopped walnuts
  • 2 cloves garlic, minced
  • ½ cup vegetable broth
  • 2 tablespoons extra-virgin olive oil
  • 1 teaspoon dried oregano
  • ½ teaspoon dried thyme
  • ½ teaspoon paprika
  • Salt and black pepper, to taste
  • 2 tablespoons fresh parsley, chopped
  • 1 tablespoon fresh lemon juice

 Step-by-Step Instructions

  1. Preheat the oven: Set the oven to 375°F (190°C). Lightly grease a baking dish with olive oil.
  2. Prepare the vegetables: Peel the beets and sweet potatoes and slice both very thinly and evenly. A mandoline can make this easier.
  3. Make the seasoning: In a small bowl, combine olive oil, minced garlic, oregano, thyme, paprika, black pepper, and lemon juice.
  4. Start layering: Arrange a layer of sweet potato slices in the baking dish. Add a layer of beet slices and sprinkle with a little feta and walnuts.
  5. Repeat: Continue alternating the vegetables with feta and walnuts until everything is used.
  6. Add broth: Carefully pour the vegetable broth around the edges of the dish.
  7. Season: Drizzle the remaining olive-oil mixture over the top.
  8. Cover and bake: Cover tightly with foil and bake for 35–40 minutes.
  9. Finish uncovered: Remove the foil and bake for another 15–20 minutes, until the vegetables are tender and the top is lightly golden.
  10. Rest and garnish: Let the gratin rest for 5–10 minutes. Sprinkle with fresh parsley and a few extra walnuts before serving.

 Healthy Benefits

  • Beets: Provide fiber and naturally occurring plant compounds.
  • Sweet potatoes: Offer fiber and beta-carotene.
  • Walnuts: Add plant-based fats and some protein.
  • Feta: Provides protein and calcium.
  • Olive oil: A staple of Mediterranean-style eating and a source of unsaturated fat.
  • Herbs and garlic: Add plenty of flavor without needing heavy sauces.

Pro Tips

  • Slice the vegetables very thinly and evenly so they cook at the same rate.
  • Pat beets dry before layering to prevent the gratin from becoming watery.
  • For extra browning, place the dish under the broiler for 1–2 minutes at the end—watch carefully.
  • Toast the walnuts beforehand for deeper flavor.
  • Let the gratin rest before slicing; it will hold together better.

 Frequency

This is best enjoyed as part of a varied diet. It works especially well as a weekly vegetarian side dish or occasional meat-free main course.

 Q&A

Q: Can I make this ahead of time?
Yes. Assemble it several hours ahead and refrigerate until ready to bake.

Q: Can I use goat cheese instead of feta?
Absolutely. Goat cheese gives the gratin a softer, creamier texture.

Q: Can I make it vegan?
Yes. Replace feta with a plant-based feta alternative and use vegetable broth.

Q: Can I use pecans instead of walnuts?
Yes. Pecans, almonds, or hazelnuts are delicious alternatives.

Q: How do I store leftovers?
Refrigerate in an airtight container and enjoy within about 3–4 days.
