Tomato galette recipe
A comforting, hearty galette topped with fresh, in season tomatoes.
Ingredients
For the galette dough
- 200 grams plain flour (plus extra for dusting)
- ½ tsp salt
- 150 grams butter
- 80 grams sour cream
- 1½ tbsp white wine vinegar
- 60 ml ice water
- 1 beaten egg
For the topping
- 1 white onion
- 125 grams semi-hard or hard cheese (nutty, flavoursome cheeses like gruyere work well)
- 1 bunch fresh thyme
- 1 tsp butter
- 400 grams fresh cherry or heritage tomatoes
- Pinch salt and pepper
Steps
- Mix the plain flour and salt.
- Rub in the diced butter with your fingers until the mixture resembles breadcrumbs.
- Combine the sour cream, white wine vinegar and 50ml of the ice water. Add to the butter and flour mixture.
- Bring the dough together, adding the rest of the water if the mixture isn’t too wet. This is a sticky dough so you may need additional flour and opt to skip the extra water. Knead once or twice to bring into a smooth ball.
- Wrap and chill the dough for at least 1.5 hours.
- Meanwhile, slice the onion and fry with a heaped teaspoon of butter until soft.
- Slice each tomato in half if using cherry-sized tomatoes, or into slices if larger. Sprinkle with salt and leave to sit for at least ten minutes. Afterwards, mop up as much liquid as possible using a paper towel.
- Preheat the oven to 180℃ (fan).
- Flour the work surface and roll the dough out until it is around 30 cm in diameter. As the dough will get sticky again quickly, it can be easier to roll the dough out between two pieces of parchment. When rolled out to 30cm, lift the bottom sheet of parchment onto a baking tray.
- Combine the grated cheese, onions and fresh thyme. Season with pepper. Spread the mixture onto the rolled out dough, leaving a 5cm gap at the edges.
- Top with the tomatoes. Arrange cherry tomatoes cut-side up. Or arrange larger sliced tomatoes so they overlap slightly. Pat dry again.
- Now fold in the edges of the dough in rough pleats. This doesn't need to be perfect!
- Chill the galette in the fridge for at least 15 minutes or until the dough feels firm again.
- Remove from the fridge and brush the edges with beaten egg. Bake in the oven for 35-40 minutes until the edges are golden brown.
- Leave to cool for 5 minutes before serving.
Recipe Notes
- For the ice water: measure out 60ml of water and pour into a small freezable container. Place in the freezer for 15-20 minutes until almost beginning to freeze.
- This is a sticky dough, so you'll need to keep it as cold as possible and work quickly.
