Ingredients
Vegetable Layers
2 large sweet potatoes, peeled and thinly sliced
2 cups butternut squash, peeled and thinly sliced
2 large carrots, peeled and thinly sliced
2 tbsp olive oil
Salt and black pepper to taste
½ tsp dried thyme or rosemary (optional)
Filling & Toppings
1 to 1½ cups feta cheese, crumbled
½ cup walnuts, toasted and chopped
½ cup fresh herbs (parsley, spinach, or rosemary), optional
Honey Balsamic Glaze
2–3 tbsp honey
1–2 tbsp balsamic vinegar
¼ cup dried cranberries (optional but recommended for depth)
1–2 tbsp water (as needed to adjust consistency)
Instructions
Prepare the Vegetables
Preheat oven to 190°C (375°F). Thinly slice sweet potatoes, butternut squash, and carrots evenly so they cook at the same rate. Toss them in olive oil, salt, pepper, and thyme or rosemary.
Assemble the Gratin
Lightly grease a baking dish. Layer vegetables in a slightly overlapping pattern, alternating colors for visual appeal. Sprinkle crumbled feta between some layers and reserve the rest for topping.
Bake the Vegetables
Cover with foil and bake for 30 minutes. Remove foil and bake for another 15–25 minutes until vegetables are tender and slightly caramelized at the edges.
Make the Honey Balsamic Glaze
In a small saucepan, combine honey, balsamic vinegar, cranberries, and water. Simmer on low heat for 5–8 minutes until slightly thickened and glossy. Stir occasionally so cranberries soften and release flavor.
Add Toppings
Once the gratin is baked, sprinkle toasted walnuts and remaining feta on top. Drizzle generously with warm honey balsamic glaze.
Rest and Serve
Let it rest for 10 minutes before serving so it sets slightly and layers hold together better.
Tips
Slice vegetables evenly for consistent roasting.
Use a mandoline for thin, uniform layers.
Don’t skip toasting walnuts; it enhances their nutty flavor.
Slightly underbake, then rest the dish so it finishes cooking gently.
Use high-quality balsamic vinegar for a richer glaze.
Add feta in layers, not just on top, for deeper flavor.
Cover while baking first to keep vegetables soft and tender.
Uncover at the end to allow caramelization.
Let glaze cool slightly before drizzling so it thickens naturally.
Fresh herbs added at the end give brightness and freshness.

Extra Creamy Version: Add a light cream or béchamel layer between vegetables.
Vegan Version: Replace feta with vegan cheese or cashew cream.
Nut-Free Option: Skip walnuts and add roasted pumpkin seeds instead.
