This quick veggie tart is packed with flavour. Golden puff pastry topped with basil pesto, sweet caramelised onions and tangy feta really packs a punch. I love to serve my Courgette and Feta Tart with a yummy green salad to bulk it up for a light summer lunch or dinner.

Ingredient notes:

Two zucchinis, two sheets of puff pastry, feta cheese, grated cheese, two red onions, balsamic vinegar, brown sugar, pesto, and fresh basil on a countertop.

Pastry: This recipe calls for puff pastry. But you could also use short, unsweetened pastry or even gluten-free pastry if you prefer.
Courgette: This is a great recipe to use when courgettes (also referred to as zucchini) are in season, plentiful and affordable.
Onions: Red onions provide a lovely sweet flavour and colourful element to the tart. You can also use brown onions if thats what you have to hand.

Step by step instructions:

Preheat the oven to 180°C fan bake. Line a large oven tray with baking paper. Place a frying pan on a medium-low heat then heat the butter. Add the red onions and sauté for 5 minutes until they just start to brown. Add the balsamic vinegar, brown sugar and water. Cook on low for another 5 minutes or until the onions have caramelised. They will continue to cook in the oven too.

Place the pastry sheets on the oven tray, overlapping them by 1-2cm to create a long oblong. Score the overlap with a knife, use a little water and press with your fingers join them together. Then, score a border of 2cm around the outside edge. Don't cut all the way through.

Recipe FAQs:

Can I use a different cheese instead of feta?

Absolutely. Goat cheese, ricotta, or crumbled blue cheese are delicious alternatives, depending on your taste preference.

Can I prepare this tart ahead of time?

You can prepare the caramelised onions and even assemble the tart (without baking) a few hours in advance. Store it in the fridge and bake just before serving.

Storage:

Store any leftover Courgette Tart in the fridge in an airtight container. To reheat, use the oven. The microwave is quick but can make the pastry soggy. You can pop in a frying pan or air fryer to crisp up the pasty again.

Top tips:

To get ahead, you can make the caramelised onion in advance. Or, you can use store bought if you want to make it super quick and easy.
