Ingredients

For the Vegetables:

2 medium sweet potatoes, peeled and sliced into ¼-inch rounds
2 medium beets, peeled and thinly sliced
2 medium Yukon Gold potatoes, peeled and thinly sliced
1 large yellow potato, thinly sliced, optional
3 tablespoons extra-virgin olive oil
3 cloves garlic, minced
1 teaspoon dried thyme
½ teaspoon dried oregano
½ teaspoon smoked paprika
½ teaspoon black pepper
½ teaspoon salt, or to taste

For the Topping:

¾ cup crumbled feta cheese
¾ cup roughly chopped walnuts
1 tablespoon fresh thyme leaves
1 tablespoon extra-virgin olive oil, for drizzling

Optional Finishing Ingredients:

1 tablespoon fresh chopped parsley
1 teaspoon lemon juice
1 teaspoon balsamic glaze
A little extra crumbled feta

Instructions

Step 1: Prepare the Oven

Preheat your oven to 400°F (200°C). Lightly grease a rectangular baking dish with olive oil.

Choose a baking dish large enough to arrange the vegetable slices in overlapping rows. This helps the vegetables cook evenly and creates the beautiful layered appearance.

Step 2: Prepare the Vegetables

Wash and peel the sweet potatoes, beets, and regular potatoes.

Using a sharp knife or mandoline, carefully slice all the vegetables into approximately ¼-inch-thick rounds.

Try to keep the slices similar in thickness so they cook evenly. If the beets are particularly large, cut them in half before slicing.

Keep the beet slices separate while preparing the other vegetables to prevent their natural colour from staining everything.

Step 3: Prepare the Seasoning Mixture

In a small bowl, combine olive oil, minced garlic, dried thyme, oregano, smoked paprika, black pepper, and salt.

Whisk until everything is evenly combined.

This aromatic mixture will coat the vegetables and help them develop a delicious roasted flavour.

Step 4: Arrange the Vegetable Slices

Arrange the sweet potato, beet, and potato slices upright or slightly overlapping in alternating rows inside the prepared baking dish.

Continue layering until the dish is filled.

Alternating the different vegetables creates a beautiful colourful pattern and ensures that every serving includes a variety of flavours.

Step 5: Add the Olive Oil and Herbs

Drizzle the seasoned olive oil mixture evenly over the vegetables.

Use a pastry brush or your hands to make sure the seasoning reaches as many slices as possible.

Sprinkle a little additional thyme over the top.

Step 6: Begin Baking

Cover the baking dish loosely with aluminium foil and place it in the preheated oven.

Bake for approximately 25–30 minutes.

The foil helps trap moisture and steam, the vegetables slightly, allowing the thicker slices to begin softening without drying out.

Step 7: Add the Feta and Walnuts.

Carefully remove the baking dish from the oven.

Remove the foil and sprinkle the crumbled feta cheese and chopped walnuts evenly over the vegetables.

Add a little fresh thyme for extra fragrance.

Step 8: Finish Roasting

Return the uncovered baking dish to the oven.

Bake for another 15–20 minutes, or until the vegetables are fork-tender and the edges are lightly golden.

The feta should become warm and slightly softened, while the walnuts become fragrant and toasted.

Cooking time can vary depending on the thickness of the vegetable slices and your oven.

Step 9: Garnish and Serve

Remove the dish from the oven and allow it to rest for approximately 5 minutes.

Finish with fresh parsley, a light drizzle of olive oil, and a little lemon juice if desired.

For a slightly sweet and tangy finish, add a small drizzle of balsamic glaze.

Serve warm and enjoy!

Notes

Slice Evenly: Keeping the vegetables approximately the same thickness helps them cook at the same rate.
Choose Firm Vegetables: Fresh, firm sweet potatoes, beets, and potatoes provide the best texture.
Keep Beets Separate: Beets naturally release colour, so handle them separately during preparation if you want to preserve the different vegetable colours.
Use Fresh Feta: Crumbled feta provides a delicious salty contrast to the sweet roasted vegetables.
Watch the Walnuts: Add walnuts during the final baking stage to prevent them from burning.
Check for Doneness: Insert a fork into the thickest vegetable slice. It should slide through easily when the vegetables are ready.
Adjust the Seasoning: Feta is naturally salty, so taste before adding extra salt.
Vegetarian Option: Use a vegetarian-friendly feta cheese if needed.

Helpful Tips for the Best Roasted Vegetable Bake

Use a mandoline: A mandoline slicer makes it easier to achieve thin, uniform vegetable rounds. Always use its safety guard.
Don’t Overcrowd the Dish: Arrange the slices with a little space so heat can circulate.
Use Good-Quality Olive Oil: Extra-virgin olive oil adds wonderful flavour and complements the Mediterranean ingredients.
Roast Until Tender: Different vegetables may cook at slightly different speeds. If some slices need more time, continue roasting until everything is tender.
Add Cheese Near the End: Adding feta too early can cause it to dry out during longer baking.
Toast the Walnuts Carefully: If you prefer extra crunch, toast them separately in a dry skillet before adding them.
Add Fresh Herbs: Fresh thyme, rosemary, and parsley all work beautifully.
Finish with Lemon: A little lemon juice brightens the rich roasted flavours.
Make It Your Own: Add carrots, parsnips, or butternut squash for additional colour and flavour.
