Sweet Potato, Caramelised Onion, Feta Tart

This savoury tart is a delicious combination of roasted sweet potato, caramelised onion, and creamy feta, all nestled on a flaky puff pastry base. It’s simple to prepare yet delivers impressive flavours that make it a favourite for a light dinner, easy lunch, or special occasions.

As much as I love cooking, I’m a busy lady and I just don’t have time to spend hours in the kitchen each day. So I’m always trying to create cooking shortcuts, either by making more than I need (so I get more than one meal from the effort) or by cooking extra of one part of the meal and then reworking it into another meal.

This Sweet Potato, Caramelised Onion and Feta Tart is an example of the latter. When my kids were babies I would bake a heap of spiced sweet potato – so I wasn’t just cooking for them, I’d mash some of it for them and the rest was made into this tart or tossed into a salad or curry for dinner.

Health benefits

Sweet potatoes are rich in beta-carotene, which supports vision and immune health. Onions contain antioxidants and compounds that promote heart health, while feta cheese adds a boost of protein and calcium.

Ingredients

This recipe features roasted sweet potatoes seasoned with cinnamon, caramelised onions cooked with balsamic vinegar, crumbled feta cheese, and a buttery puff pastry base. Rocket leaves and a balsamic dressing add a fresh finish.

How to make this sweet potato caramalised onion feta tart

Begin by roasting sweet potato cubes seasoned with cinnamon until tender. While they roast, caramelise onions in butter or olive oil, adding a touch of rice malt syrup and balsamic vinegar for sweetness. Assemble the tart by layering caramelised onions, roasted sweet potato, and crumbled feta on puff pastry sheets, leaving a border for the crust. Bake until golden brown and top with dressed rocket leaves before serving.

Serving suggestions and how to store

Serve this delicious tart warm with a leafy green salad for a complete meal. Leftovers can be stored in an airtight container in the fridge for up to three days and reheated in the oven to maintain the pastry’s crispness.

Vary this sweet potato caramalised onion feta tart to suit

For a dairy-free version, opt for coconut oil and vegan cheese, and ensure the pastry is free of dairy. Vegans can use olive oil, vegan puff pastry, and cashew cheese. For a coconut-free variation, stick with butter or ghee as your cooking fat. Another option is to swap the sweet potato with roast pumpkin.
