👩🍳 Instructions
1️⃣ Preheat & Prepare
Preheat oven to 375°F (190°C).
Lightly grease a 9×9-inch baking dish.
2️⃣ Slice the Vegetables
Slice beets and sweet potatoes thinly (about ⅛ inch thick). A mandoline works best for even slices.

4️⃣ Layer the Gratin
Arrange a layer of sweet potatoes in the dish.
Add a layer of beets.
Spoon some of the feta mixture over the top.
Repeat layers until ingredients are used, finishing with feta mixture on top.
Season lightly with salt and pepper between layers.
5️⃣ Add Topping
Sprinkle walnuts and Parmesan on top. Drizzle with olive oil.
6️⃣ Bake
Cover with foil and bake for 35 minutes.
Remove foil and bake another 15–25 minutes, until vegetables are tender and top is golden.
7️⃣ Rest & Serve
Let rest for 10 minutes before slicing. Garnish with extra parsley if desired.
