- 1 can (425 g / 15 oz) chickpeas, drained and rinsed
- 1 large red bell pepper (approx. 200 g), diced into 2 cm (¾-inch) pieces
- 1 large red onion (approx. 200 g), cut into 8-12 wedges
- 450-500 g (3 cups) potatoes, such as Yukon Gold or Red Bliss, cut into 2 cm (¾-inch) cubes
- 45 ml (3 tablespoons) extra virgin olive oil
- 15 ml (1 tablespoon) paprika
- 10 ml (2 teaspoons) dried basil
- 15 ml (3 teaspoons) garlic powder
- 15 ml (3 teaspoons) dried oregano
- 5 ml (1 teaspoon) dried dill
- 5 ml (1 teaspoon) dried parsley
- 4 ml (¾ teaspoon) fine sea salt, optional (adjust to taste)
- 2.5 ml (½ teaspoon) freshly ground black pepper
- For the Tzatziki Sauce:
- ½ a large cucumber (approx. 150 g), grated with excess moisture removed
- 480 ml (2 cups) plain plant-based yogurt (or Greek yogurt for non-vegan option)
- 70 g (½ cup) raw cashews, soaked in hot water for 15 minutes and drained (optional, for extra creaminess)
- 225 g (1 cup) firm tofu, pressed (optional, for extra body and protein)
- 2 large garlic cloves, minced
- 30 ml (2 tablespoons) red wine vinegar
- 60 ml (¼ cup) fresh dill, finely chopped
- 5 ml (1 teaspoon) fine sea salt
- 2.5 ml (½ teaspoon) black pepper
- 5 ml (1 teaspoon) fresh lemon juice
Instructions
- Preheat your oven to 200°C (400°F). Ensuring the oven is fully preheated is crucial for achieving perfectly caramelized and tender roasted vegetables, preventing them from steaming.
- Prepare the vegetables. Thoroughly rinse and drain the canned chickpeas. On a sturdy cutting board, cut the potatoes into uniform 2 cm (¾-inch) cubes, dice the red bell pepper into similar-sized pieces, and cut the red onion into evenly sized wedges. Uniform cutting promotes even cooking.
- Create the aromatic spice blend. In a small bowl, combine the paprika, dried basil, garlic powder, dried oregano, dried dill, dried parsley, salt (if using), and freshly ground black pepper. Mix them well to ensure an even distribution of flavors.
- Season the vegetables. Transfer the cubed potatoes, diced bell pepper, onion wedges, and drained chickpeas to a large baking sheet. Drizzle with the 45 ml (3 tablespoons) of olive oil, then sprinkle the prepared spice blend generously over all the ingredients. Toss everything together thoroughly with your hands until every piece is evenly coated. Spread the seasoned vegetables in a single layer across the baking sheet. Avoid overcrowding the sheet, as this can lead to steaming instead of roasting.
- Roast the vegetables. Place the baking sheet in the preheated oven and roast for a total of 40 minutes. Halfway through the cooking time (after 20 minutes), carefully remove the sheet from the oven and stir the vegetables to ensure even browning. Continue roasting until the vegetables are golden brown, tender when pierced with a fork, and exhibit delicious caramelized edges.
- Blend the tzatziki sauce base. While the vegetables are roasting, prepare the tzatziki. In a high-speed blender, combine the plain plant-based yogurt, pre-soaked and drained cashews (if using), pressed firm tofu (if using), and minced garlic cloves. Blend until the mixture is completely smooth and creamy. The cashews and tofu contribute significantly to the sauce's rich texture and body.
- Finish the tzatziki sauce. Grate the half cucumber using a box grater, then firmly squeeze out as much excess water as possible. This step is essential to prevent a watery tzatziki. Transfer the blended yogurt mixture to a medium bowl and stir in the grated cucumber, finely chopped fresh dill, red wine vinegar, salt, black pepper, and fresh lemon juice. Mix well and taste, adjusting any seasonings as needed for your preference.
- Assemble and serve. Once the roasted vegetables are ready, spread a generous layer of the creamy tzatziki sauce onto individual bowls or plates. Pile the warm, roasted vegetables and chickpeas on top of the tzatziki. Serve immediately for the best flavor and texture, enjoying the contrast between the warm, savory vegetables and the cool, tangy sauce.

Tools You’ll Need
- Large baking sheet
- Large mixing bowls
- Sharp knife
- Cutting board
- High-speed blender or food processor
- Box grater
- Measuring cups and spoons
- Silicone spatula or spoon for stirring
Essential Success Tips
- Do not overcrowd the baking sheet when roasting the vegetables; use two sheets if necessary to ensure they roast and caramelize properly, rather than steam.
- Cut all vegetables to a similar size to promote even cooking. Inconsistent sizes can lead to some pieces being overcooked and others undercooked.
- Thoroughly squeeze out all excess moisture from the grated cucumber for the tzatziki. This is critical for achieving a thick, creamy sauce that won't become watery.
- Always taste and adjust the seasoning for both the roasted vegetables and the tzatziki sauce before serving. A little extra salt, pepper, or lemon juice can make a big difference.
- For the best texture and flavor, use a high-quality extra virgin olive oil for roasting your vegetables.
Professional Cooking Secrets
- To enhance the roasted vegetables' crispiness, consider flipping on the convection setting (if your oven has one) for the last 5-10 minutes of cooking. This intense, dry heat promotes extra browning.
- For a deeper, more complex spice profile, lightly toast whole cumin seeds or coriander seeds in a dry pan before grinding them with your other spices. This awakens their aromatic compounds.
- If time allows, marinate your cut vegetables with the olive oil and spice blend for at least 30 minutes (or up to a few hours in the refrigerator) before roasting. This allows the flavors to penetrate more deeply.

Notes
- Storage: Leftover roasted vegetables and tzatziki can be stored separately in airtight containers in the refrigerator for up to 3-4 days. Reheat vegetables in the oven or air fryer for best texture.
- Variations: Feel free to add other vegetables like zucchini, cherry tomatoes, eggplant, or asparagus to your roast. Serve the bowls with a side of fluffy quinoa, couscous, or warm pita bread for a more substantial meal.
- Advance Preparation: The vegan tzatziki sauce can be made a day in advance and stored in the refrigerator, allowing the flavors to meld further. Just give it a good stir before serving.
Frequently Asked Questions
Can I prepare parts of this dish ahead of time?
Absolutely! The tzatziki sauce can be made up to 24 hours in advance and stored in the refrigerator. You can also chop all your vegetables a day prior and store them in an airtight container, ready for roasting.
How can I make this dish spicier?
To add a kick, include a pinch of cayenne pepper or red chili flakes to your spice blend for the vegetables. You could also drizzle a little hot sauce over the finished dish for an extra layer of heat.
What if I don't have a high-speed blender for the tzatziki?
While a high-speed blender ensures the smoothest sauce, a regular blender or even a food processor will work. Just blend for a longer duration, pausing to scrape down the sides, until you achieve the creamiest consistency possible. Soaking the cashews is especially important if you don't have a high-powered blender.
