French Mustard Tart Recipe

French Mustard Tart Recipe

This one is great for a quick lunch when you’ve not much left in your fridge but still want something damn tasty. My mam used to make this quite a lot and this tart remains very close to my heart. 


  • pastry base (short crust or puff will work great here),
  • dijon mustard,
  • 1 large tin of tuna
  • a small packet of grated cheese
  • ripe tomatoes.
  • 1 table spoon of herbes de provence. 


  • Pre-heat the oven to 180 C.
  • Roll out the pastry into the dish and prick all over the base with a fork.
  • Blind bake for 10 to 15 min. 
  • Take the pastry out of the oven and spread about 3 teaspoons of dijon mustard on the base of the pastry. 
  • Add the drained tuna and sprinkle it over the mustard. 
  • Add your grated cheese over the tuna.
  • Place your sliced tomatos atop and season them with the herbes de provence. 
  • It looked like this before the oven.

The finished product should look something like this:

This works best with a simple green salad on the side.
