There’s something deeply comforting about pulling a golden, buttery tart out of the oven — the kind that fills the whole kitchen with a soft, savoury scent. This cheesy leek and thyme tarte is one of my absolute favourites. It’s simple, seasonal, and packed with flavour.

The best part? The pastry is made without egg yolk — it’s beautifully short, crumbly, and easy to work with. Perfect for anyone who prefers an egg-free pastry or just wants that classic melt-in-the-mouth texture.

Ingredients

For the Pastry (Egg-Free Shortcrust)

• 250g plain flour

• 125g cold unsalted butter, cubed

• Pinch of salt

• 3–4 tbsp cold water

  
  

For the Filling

• 2 large leeks, finely sliced

• 25g butter

• 1 tbsp olive oil

• 1 tsp fresh thyme leaves (or ½ tsp dried)

• 150g grated mature cheddar (or a mix of cheddar and gruyère for extra depth)

• 4 Large eggs

• Salt and black pepper to taste

  
  

Method

Step 1: Make the Pastry

1. In a large bowl, rub the butter into the flour and salt with your fingertips until the mixture resembles breadcrumbs.

2. Add the cold water a tablespoon at a time, pulling the breadcrumbs together until the dough just comes together.

3. Bring it into a ball, wrap in clingfilm, and chill for at least 30 minutes.

(Tip: Don’t overwork the dough — that’s the secret to a tender pastry!)

Step 2: Roll & Blind Bake

1. Preheat your oven to 180°C (fan).

2. Roll out the chilled pastry on a lightly floured surface and line a 23cm tart tin.

3. Prick the base with a fork, line with baking paper, and fill with baking beans.

4. Bake for 15 minutes, remove the paper and beans, then bake for another 5 minutes until pale golden.

Step 3: Cook the Leeks

1. Meanwhile, melt the butter with the olive oil in a frying pan.

2. Add the sliced leeks and thyme, season with salt and pepper, and cook gently for about 10 minutes until soft and sweet but not browned.

3. Allow to cool slightly.

Step 4: Assemble the Filling

1. In a jug, beat the eggs, then stir in most of the cheese (saving a little for the top).

2. Spread the cooked leeks evenly over the pastry base, then pour over the egg mixture.

3. Sprinkle the remaining cheese on top.

Step 5: Bake to Perfection

1. Bake for 25–30 minutes, until the filling is just set and the top is beautifully golden.

2. Allow to cool for at least 10 minutes before slicing.

🌿 Serving Suggestions

• Serve warm with a crisp green salad and a chilled glass of white wine.

• For a rustic supper, pair with new potatoes tossed in butter and herbs.

• It also tastes delicious cold — perfect for picnics or lunchboxes.

✨ Tips & Variations

• Swap cheddar for a punchy blue cheese if you like stronger flavours.

• Add caramelised onions for extra sweetness.

• For a gluten-free version, use a shortcrust alternative and keep the filling the same.

🏡 A Little Note from My Kitchen

I love making this tarte for breakfast — the gentle bubbling of leeks on the hob, thyme filling the kitchen, pastry cooling on the counter. It’s slow, simple cooking at its best. And the result is a dish that looks beautiful and tastes even better.
