Step 1: Prepare the Vegetables
Wash, peel, and slice all vegetables into thin rounds so they cook evenly.
Try to keep the slices close to the same thickness for the best texture.
Step 2: Season Everything
Place the sliced vegetables into a large bowl.
Add:
- Olive oil
- Garlic powder
- Thyme
- Oregano
- Salt
- Black pepper
Toss everything well until the vegetables are fully coated.
Step 3: Arrange in the Baking Dish
Preheat your oven to 400°F (200°C).
Arrange the vegetable slices upright in rows inside a greased baking dish, alternating colors for a beautiful presentation.
Tuck the slices tightly together.
Step 4: First Bake
Cover the dish loosely with foil.
Bake for 35 minutes until the vegetables begin to soften.
Step 5: Add Walnuts and Cheese
Remove the foil carefully.
Sprinkle:
- Crumbled feta cheese
- Walnuts
across the top of the vegetables.
If you like a touch of sweetness, drizzle lightly with honey.
Step 6: Final Roast
Return the dish to the oven uncovered.
Bake another 20–25 minutes until:
- The edges are golden
- Walnuts are toasted
- Cheese becomes slightly creamy and browned
Step 7: Garnish and Serve
Remove from the oven and let it rest for 5 minutes.
Top with chopped fresh parsley before serving.
Serve warm as:
- A holiday side dish
- A healthy vegetarian meal
- A comforting family dinner
Tips for the Best Flavor
- Add goat cheese instead of feta for extra creaminess.
- Sprinkle chili flakes for a spicy kick.
- Use pecans instead of walnuts if preferred.
- Thin slices roast faster and caramelize beautifully.
Storage
Store leftovers covered in the refrigerator for up to 4 days.
