Gluten-Free Jam Tarts: A Crisp, Buttery UK Recipe

Gluten-free jam tarts are a British teatime favourite: small pastry cases filled with jam and baked until the edges are lightly golden. This version uses a carefully chilled, buttery shortcrust that is easy to press into a tin and pairs well with raspberry, strawberry or another favourite jam.

Ingredients

1⅔ cups (200 g) gluten-free plain flour blend, preferably one containing xanthan gum
⅓ cup (40 g) ground almonds
⅓ cup (40 g) caster sugar
½ cup (115 g) cold unsalted butter, cut into small cubes
1 medium egg, beaten
1–2 tbsp (15–30 ml) cold water, as needed
½ cup (150 g) jam, such as raspberry, strawberry or apricot
A little gluten-free flour blend, for dusting

Instructions

Make the pastry. Put the gluten-free flour, ground almonds and sugar in a mixing bowl and stir to combine. Add the cold butter and rub it in with your fingertips until the mixture resembles fine breadcrumbs. You can also pulse the ingredients briefly in a food processor.
Bring the dough together. Add the beaten egg and mix with a fork. Add cold water a teaspoon at a time, just until the dough holds together when pressed; it should not feel wet or sticky. Shape it into a flat disc, wrap or cover it, and chill for 20 minutes. This helps the butter firm up and makes the dough easier to handle.
Prepare the tin and oven. Heat the oven to 350°F (180°C), or 320°F (160°C) for a fan oven. Lightly grease a 12-hole shallow bun or tart tin. Dust a work surface and rolling pin with a little gluten-free flour.
Cut the tart shells. Roll the dough to about ⅛ inch (3 mm) thick. Gluten-free pastry can crack, so work gently and press any cracks together with your fingertips. Cut 12 rounds about 3½ inches (9 cm) wide, re-rolling scraps as needed. Ease each round into a hole in the tin without stretching it. If the dough is too soft to lift, roll it between two sheets of baking parchment.
Fill with jam. Spoon about 2 teaspoons (12–13 g) of jam into each pastry case. Keep the filling below the rim; jam bubbles as it bakes and can spill over the sides. If your jam is very firm, stir it briefly to make it easier to portion.
Bake. Bake for 15–18 minutes, until the pastry edges are lightly golden and the jam is bubbling. The pastry may still look pale on the bottom, so check one tart carefully if you are unsure. Avoid baking until the jam darkens, as it can turn bitter and become very hot.
Cool before removing. Leave the tarts in the tin for 10 minutes so the pastry can firm up. Run a small blunt knife around the edges if needed, then transfer them to a wire rack to cool completely. Hot jam can cause burns, so do not taste the filling straight from the oven.

Tips

Check the flour blend. Use a plain gluten-free blend suitable for pastry. If it does not contain xanthan gum, add ¼ teaspoon to help the dough hold together. Check the blend and other packaged ingredients for gluten-free labelling, especially if you are cooking for someone with coeliac disease.
Keep the butter cold. Warm pastry is harder to roll and can shrink or crumble. If the dough softens while shaping, chill it for another 10 minutes before continuing.
Use a light hand with water. Flour blends absorb liquid differently. Add it gradually; too much water makes the pastry sticky and may leave it tough rather than tender.
Measure the jam modestly. Two teaspoons per tart is usually enough. Overfilling is the most common cause of jam bubbling onto the tin and sticking to the pastry edges.

Serving Suggestions

Serve the tarts fully cooled with tea or coffee for an afternoon treat, or arrange them on a plate for a party. For a simple dessert, add a spoonful of softly whipped cream or a scoop of vanilla ice cream alongside, rather than on top, so the pastry stays crisp. A few fresh berries make a colourful accompaniment.

Variations

Change the flavour by using different jams: blackcurrant gives a sharper filling, while apricot is mellow and strawberry is a familiar choice. For a mixed batch, divide the jam among several flavours and note which tart is which before baking. You can replace the ground almonds with the same weight of gluten-free flour, though the pastry will be a little less rich and tender; avoid this swap if serving someone with a nut allergy unless all ingredients and equipment are suitable.

For a dairy-free version, use a firm dairy-free baking block in place of butter and check that the jam is suitable. The pastry may have a slightly different texture, so chill it well before rolling. To make the recipe egg-free, use 2–3 tablespoons (30–45 ml) cold water instead of the egg, adding it gradually; the dough will be more delicate and may need extra chilling.

Storage and Reheating

Once completely cool, store the tarts in an airtight container at room temperature for up to 2 days, or refrigerate them for up to 4 days. Refrigerate within 2 hours if the room is warm or if you prefer chilled storage. The pastry softens gradually as it sits, so room-temperature storage gives the crispest texture. To refresh, warm the tarts on a baking sheet at 300°F (150°C) for 5–7 minutes, then let them cool briefly; the jam will be hot. Do not microwave them, as this can make the pastry soft and the filling unevenly hot. Freeze cooled tarts in a sealed container for up to 2 months and thaw at room temperature before serving.

Frequently Asked Questions

Can I make gluten-free jam tart pastry ahead?
Yes. Make and wrap the dough, then refrigerate it for up to 24 hours. Let it sit at room temperature for 5–10 minutes if it is too firm to roll, and handle it gently to prevent cracking.

Why did my pastry crumble?
Gluten-free pastry has less stretch than wheat pastry and can crack if it is too dry or warm. Add water gradually until it holds together when pressed, chill it before rolling, and patch small cracks with your fingers.

Do I need to blind bake the tart shells?
No. These shallow tart shells bake through in the same time as the jam filling. Blind baking can overcook the pastry before the filling has had a chance to heat.

Can I use a different tin?
A shallow 12-hole bun or tart tin gives the best balance of pastry and filling. A deeper muffin tin makes smaller, deeper cases that need more pastry and may take longer to bake, so check that the edges are golden and the bases look set.

How do I keep the jam from overflowing?
Fill each case with about 2 teaspoons and leave a little space below the pastry rim. If the jam is especially runny, use slightly less; it will bubble as it heats.

Can I make these without ground almonds?
Yes. Replace the ground almonds with ⅓ cup (40 g) gluten-free plain flour. The pastry will be a little less tender, but it will still work; do not use this substitution for someone with a nut allergy without checking the rest of the ingredients and avoiding cross-contact.
