How to Make Layered Beet, Sweet Potato & Feta Gratin with Walnuts
Step 1: Prep the Vegetables
Begin by peeling the beets and sweet potatoes, then slicing them as thinly as you can—about 1/8 inch is ideal. Thin slices ensure that all the layers bake evenly and get tender. Don’t forget the onion; slice it into wispy half-moons. You’ll want consistency here, so the slices melt together during baking.
Step 2: Toss with Seasonings
Place your sliced beets, sweet potatoes, and onion into a large bowl. Drizzle with olive oil, sprinkle in dried thyme or rosemary, and season with a generous pinch of salt and black pepper. Toss everything together gently, making sure every vegetable slice is glistening and seasoned—it’s the key to building flavor in every layer.
Step 3: Layer in the Baking Dish
Lightly grease a medium baking dish (a casserole or an 8×8-inch dish works well). Now, let the artistry begin: arrange sweet potato and beet slices in neat overlapping rows, tucking in a few onion slices here and there. Sprinkle a handful of crumbled feta and walnuts between layers, building up shades of orange, magenta, and creamy white. Keep layering until you’ve used up all the veggies, cheese, and nuts.
Step 4: Add Cream (Optional) and Bake
If you want extra richness, drizzle the heavy cream or coconut cream evenly over the very top. Cover the dish snugly with foil and transfer to a preheated oven at 190°C (375°F). Bake for 35 to 40 minutes, until the vegetables start to soften. Uncover and return the dish to the oven for another 10 to 15 minutes, letting the top turn a tempting golden-brown and the walnuts toast up.
Step 5: Rest and Serve
Once the Layered Beet, Sweet Potato & Feta Gratin with Walnuts is bubbling and golden, remove it from the oven and let it rest for about five minutes. This step allows the juices to settle, making it easier to neatly slice and serve. Garnish with a sprinkle of fresh herbs or another flurry of chopped walnuts for a bit of flair.

Make Ahead and Storage
Storing Leftovers

To reheat, cover the gratin loosely with foil and warm in a 180°C (350°F) oven until heated through—usually about 15 minutes. If you’re in a hurry, microwave individual pieces, but be sure to cover the dish so nothing dries out.
