Light jam tart: oil-based shortcrust

Ingredients (10 slices)

• 300 g all-purpose flour
• 120 g sugar
• 2 eggs
• 80 ml vegetable oil
• 8 g baking powder
• Zest of 1 lemon
• 1 pinch of salt
• 250 g jam or preserve

Quick method

1. In a bowl, mix eggs, sugar, oil, lemon zest, and salt.
2. Add flour and baking powder and knead quickly into a soft dough.
3. Press about 2/3 of the dough into a lined 24 cm tart pan.
4. Spread the jam evenly.
5. Use the remaining dough for strips and bake at 175 C for 30-35 minutes.

Why it works

Oil-based shortcrust is lighter but still crumbly. No long resting time and it comes together fast. The jam adds sweetness and aroma, making this tart perfect for breakfast or snacks.

Oil shortcrust: easy and fast

Oil makes the dough soft and easy to roll. No cold butter needed. I knead quickly to keep the dough tender so it bakes up crumbly.

Choosing the jam

Jam is the star. I often use apricot or mixed berries. For a milder taste, peach works well. For a brighter note, citrus marmalade is great. Just make sure the jam is thick so it does not run.

Stress-free rolling

Because the dough is soft, it can stick. Dust with flour or roll between parchment. I often press it with my hands directly into the pan for an even base.

Neat strips

Roll the dough into logs and slice into strips. A smooth pastry wheel works too. The rustic look is part of the charm, so it does not need to be perfect.

Variations I often make

• With whole wheat flour: replace 100 g of flour with whole wheat.
• With cocoa: add 2 tablespoons cocoa powder to the dough.
• With fruit: add thin apple slices on top of the jam.
• With hazelnut spread: replace part of the jam with hazelnut spread.

How I serve it

I serve it at room temperature with a light dusting of icing sugar. For a slow breakfast, I pair it with coffee or warm milk. It stays good the next day too.

Smart shopping

All ingredients are pantry staples, so the cost stays low. I choose jam based on what I already have open to avoid waste. It is a practical way to use half-empty jars.

Storage

Keep for 3-4 days under a cake dome or in a container. In hot weather, store in the fridge and bring to room temperature before serving. Oil-based crust stays tender longer.

Pan size and base

A 24 cm pan is ideal. Smaller pans make a taller tart and need a few extra minutes; larger pans make it thinner and faster to bake. I always line the base with parchment so it lifts out easily.

Short rest (optional)

Oil dough does not need a long rest, but 15 minutes in the fridge helps if your kitchen is warm. It firms up the dough and makes the strips neater.

Avoid a soggy base

Keep the base even and not too thick. If the jam is very loose, sprinkle a teaspoon of flour or breadcrumbs on the base before spreading it. It absorbs excess moisture without changing the flavor.

Adjusting sweetness

If you like a less sweet tart, reduce sugar to 100 g, especially if the jam is very sweet. I adjust depending on the jam: berries need less, apricot can take a bit more.

Cutting and serving

Slice the tart only when it is fully cool, so the crust stays clean. Dust with icing sugar right before serving so it stays visible and does not melt.

Why oil works well

Oil makes the crust tender and lighter than butter-based pastry. It also mixes faster and does not need cold butter. The result is a crumbly but light base, perfect for everyday baking.

Homemade jam

If you have homemade jam, this tart is the best way to use it. Homemade jams are often more aromatic and less sweet, so the final flavor feels balanced. I love using homemade citrus jam for a bold note.

Light glaze

For a more elegant finish, mix icing sugar with a few drops of lemon juice and drizzle lightly. Keep it thin so it does not overpower the jam. I use this when I bring the tart to friends.

Easy to transport

If you need to take it out, let it cool completely and wrap it in parchment or plastic wrap. Oil-based crust holds up well and does not crumble too easily. I often carry it to the office without issues.

Common mistakes I avoid

• Over-kneading: the crust becomes tough.
• Using runny jam: it leaks and burns.
• Overbaking: the base dries out.
• Not lining the pan: the base can break.

When I bake it

I often bake it on weekends so I have a ready breakfast for the week. It is also perfect for last-minute guests: in about an hour you have a homemade tart with no stress.

Mini guide for a crumbly crust

• Use neutral vegetable oil.
• Knead quickly without warming the dough.
• Do not add too much flour: the dough should stay soft.

My personal touch

Sometimes I add a pinch of cinnamon, especially with apple or apricot jam. It is subtle but makes the tart feel extra cozy. A tiny change that gives a new character.

Quick FAQ

Can I use olive oil? Yes, but the taste is stronger. I prefer vegetable oil for a neutral flavor.

Can I make it egg-free? Yes, use 80 ml plant milk instead of eggs, but texture changes.

Can I freeze it? Yes, slice and freeze. Thaw at room temperature.

The detail that makes the difference

The key detail is choosing a thick, fragrant jam. With 45 minutes total and Easy difficulty, this is a recipe I make often. Cost stays in the € range, especially if you use jam you already have.

Practical conclusion

This light jam tart is simple, wholesome, and always appreciated. Few ingredients, little time, and a reliable result. If you want a breakfast cake that feels like home, this is the perfect recipe.
