Spicy Vegetable Turnovers
These turnovers are basically the perfect excuse to turn your leftover roasted vegetables into something that looks like you actually planned dinner instead of just staring into the fridge hoping for inspiration.

The moment you bite through that golden, flaky puff pastry and hit the spiced vegetable filling, you’ll understand why this recipe exists – it’s comfort food that happens to use up those random vegetables sitting in your fridge.

What makes these turnovers absolutely brilliant is how the garam masala and mustard seeds transform ordinary roasted vegetables into something that tastes like you’ve been perfecting this recipe for years.

The cooling cucumber raita provides the perfect creamy contrast to all that spicy warmth, making each bite a perfect balance of heat and refreshment.

This is the kind of recipe that makes you look like a culinary genius while secretly being one of the most practical ways to avoid food waste and create something genuinely delicious.

Warning: making these will result in people asking for the recipe, and you’ll have to decide whether to share your secret or just smile mysteriously and say “it’s all about the spice blend.”

Ingredients
For the turnovers
- 1 Tbsp. vegetable oil
- 1 small onion, finely sliced
- 2 garlic cloves, crushed
- 1 green finger chilli, finely chopped
- 2 tsp. brown mustard seeds
- 2 tsp. garam masala
- 1 tsp. turmeric
- 75 g frozen peas
- 250 g mixed roasted vegetables (potatoes, parsnips and carrots), cut into 1cm pieces
- Plain flour, to dust
- 500 g block puff pastry
- 1 medium egg, beaten
- 1 tsp. nigella seeds, to sprinkle
For the raita
- 1 /2 cucumber, peeled, halved lengthways and deseeded
- 200 g Greek-style yogurt
- 4 fat radishes, cut into matchsticks
- Small handful mint leaves, finely chopped
- 1 Tbsp. lemon juice
Instructions
Prepare the spiced vegetable filling
- 1 Heat oil in a large cast iron skillet or non-stick pan over medium heat, add onion with a pinch of salt and fry for 7-8 minutes, until softened and translucent. The onions should be golden and aromatic, not browned or crispy.
- 2 Add garlic and chilli, fry for 2 minutes until fragrant, then add the brown mustard seeds, garam masala, and turmeric. Stir constantly for 1 minute to toast the spices – you’ll hear the mustard seeds start to pop and the mixture will become incredibly aromatic.
- 3 Add frozen peas and cook for 2 minutes until tender and bright green, then remove from heat. Stir in the roasted vegetables and season generously with salt and pepper. Allow the mixture to cool completely – this prevents the puff pastry from becoming soggy.
Assemble the turnovers
- 4 Preheat oven to 220°C (200°C fan) mark 7 and line a large baking tray with parchment paper. On a lightly floured surface using a kitchen scale for precision, roll out pastry to a 33cm (13in) square, about 3mm (1⁄8in) thick. Use a bench scraper to trim any uneven edges, then cut into 4 even squares using a sharp knife.
- 5 Place 1⁄4 of the vegetable mixture on one diagonal half of each square, leaving a 1cm border around the edges. Using a silicone spatula, brush the edges with beaten egg – this creates the seal that prevents filling from leaking out during baking.
- 6 Fold the empty half of pastry over the vegetables, creating triangular parcels. Press edges firmly with a fork or your fingers to seal completely, ensuring no gaps remain.
Bake the turnovers
- 7 Transfer the turnovers to the prepared baking tray using a bench scraper, spacing them 2cm apart. Brush all surfaces with the remaining beaten egg for that beautiful golden finish.
- 8 Using a sharp knife, cut 2-3 small slashes into the top of each parcel to allow steam to escape, then scatter nigella seeds over the surface. Bake for 12-15 minutes until deep golden brown and the pastry sounds hollow when tapped.
Make the raita
- 9 Meanwhile, coarsely grate the cucumber using a microplane grater or box grater, then squeeze the flesh firmly in your hands over the sink to remove excess moisture – this prevents watery raita.
- 10 In a mixing bowl, combine the squeezed cucumber with Greek-style yogurt, radish matchsticks, finely chopped mint leaves, and lemon juice. Season with salt and pepper to taste. The raita can be made up to 1 hour ahead and chilled until serving.
Recommended Equipment and Kitchen Tools
Recommended Tools (for best results)
- Cast iron skillet or large non-stick pan – Essential for properly sautéing the aromatics and spices without burning. The even heat distribution ensures the mustard seeds pop evenly and the onions caramelize beautifully
- Kitchen scale – While not absolutely necessary, measuring the puff pastry and portioning the filling accurately creates evenly sized turnovers that bake uniformly
- Silicone spatula – Perfect for stirring the spice mixture without scratching your pan and for brushing egg wash precisely around the pastry edges
- Bench scraper – Makes rolling and cutting the puff pastry much easier, and helps transfer delicate assembled turnovers to the baking tray without breaking
Helpful Upgrades
- Parchment paper – Prevents sticking and makes cleanup effortless, plus you can slide the whole sheet from tray to cooling rack
- Microplane grater – Creates the perfect texture for cucumber in the raita, removing excess moisture more effectively than a box grater
- Instant-read thermometer – While not essential for this recipe, it’s helpful for checking that reheated turnovers reach 165°F (74°C) internal temperature
Nice-to-Have Options
- Food processor – Can quickly chop the vegetables if you’re starting from raw rather than using leftover roasted vegetables
- Mandoline slicer – Creates perfectly uniform onion slices and radish matchsticks for professional-looking results
Recipe Variations and Dietary Modifications
Gluten-Free Adaptation
- Replace puff pastry with gluten-free puff pastry (available from most major brands) using the same quantities and method
- Ensure your spice blends are certified gluten-free, as some commercial spice mixes contain wheat-based anti-caking agents
- The texture will be slightly less flaky but still deliciously crispy
- Add 1 extra minute to baking time as gluten-free pastries often need slightly longer
Vegan Modifications
- Substitute the egg wash with 2 Tbsp. plant milk mixed with 1 tsp. maple syrup for golden browning
- Replace Greek yogurt in raita with thick coconut yogurt or cashew cream for the same cooling effect
- Use aquafaba (chickpea liquid) instead of egg for sealing the pastry edges
- All other ingredients are naturally vegan-friendly
Protein-Packed Version
- Add 100g cooked lentils or crumbled firm tofu to the vegetable mixture for extra substance
- Include 2 Tbsp. chopped almonds or pine nuts for texture and healthy fats
- Stir in 2 Tbsp. nutritional yeast for a subtle cheesy flavor boost
Flavor Variations
- Mediterranean style: Replace garam masala with oregano and thyme, add sun-dried tomatoes and olives
- Mexican-inspired: Use cumin and smoked paprika instead of Indian spices, add black beans and corn
- Seasonal swaps: Use butternut squash and sweet potato in autumn, asparagus and peas in spring

Smart Swaps and Ingredient Substitutions

Common Substitutions:
- Puff pastry → Phyllo dough (use 4 sheets per turnover, brush with oil between layers)
- Garam masala → Curry powder + 1/2 tsp cinnamon for similar warmth and complexity
- Brown mustard seeds → Yellow mustard seeds or 1 tsp Dijon mustard stirred into the mixture
- Greek yogurt → Thick natural yogurt strained through cheesecloth for 30 minutes
Budget-Friendly Swaps:
- Mixed roasted vegetables → Fresh diced potatoes, carrots, and onions sautéed until tender (add 10 minutes cooking time)
- Fresh mint → 1 tsp dried mint rehydrated in warm water for 5 minutes
- Nigella seeds → Black sesame seeds or poppy seeds for similar visual appeal
Pantry Emergency Substitutions:
- Green finger chilli → 1/4 tsp cayenne pepper or red pepper flakes to taste
- Fresh garlic → 1 tsp garlic powder (add with other spices to prevent burning)
- Radishes → Finely diced cucumber or thinly sliced red onion for crunch in the raita
Pro Tips for Substitutions:
- When using fresh vegetables instead of roasted, cook them until completely tender and drain excess moisture to prevent soggy pastry
- Store leftover spice blends in airtight containers for up to 6 months – they’re perfect for future batches
Make It Diabetes-Friendly

Pastry Modifications:
- Replace puff pastry with whole wheat tortillas or cauliflower wraps to reduce refined carbs by approximately 15-20g per serving
- Alternative option: Use almond flour pastry made with almond flour, egg, and a small amount of olive oil for a low-carb version
- Portion control: Make 6 smaller turnovers instead of 4 large ones to reduce carb content per serving
Vegetable Enhancements:
- Increase non-starchy vegetables: Add extra bell peppers, zucchini, or spinach to boost fiber and reduce carb density
- Add protein: Include 100g cooked chicken or 75g cooked lentils to help stabilize blood sugar response
- Boost healthy fats: Add 1 Tbsp chopped nuts or seeds to the filling for better glucose control
Raita Modifications:
- Use plain Greek yogurt (already included) for its lower carb content compared to regular yogurt
- Add extra cucumber and reduce radishes slightly to further decrease natural sugars
- Include herbs: Extra mint and cilantro add flavor without carbs
Serving Suggestions:
- Pair with protein: Serve alongside grilled chicken or a small portion of dal to create a more balanced plate
- Estimated carbs per modified serving: 20-25g (compared to original 30-35g)
