My first trip to Paris was for my 40th birthday. I remember buying a baguette sandwich from Paul’s Boulangerie and sitting on the lawn at Sacré-Cœur, overlooking the city. It’s still one of my favourite food memories. And now this baguette sandwich recipe is a go-to for lunchboxes or picnics alongside, my Homemade Sausage Rolls, Chicken Sandwiches and zesty Lemon Slice.

How To Make A French Baguette Sandwich

- Step 1: Cut the baguette in half and separate. Spread mayonnaise and Dijon mustard on the top half. Spread caramelized onion jam on the bottom half.

- Step 2: Arrange the rocket along the bottom half.

- Step 3: Cut slices of Brie and arrange them on an angle, on top of the rocket.

- Step 4: Peel off your prosciutto or jamon, twirl it into a loose rosette, then place on top of the Brie.

- Step 3: Place the top half onto the bottom half to sandwich, then cut into portions (I find 3 portions works well).

- Step 4: Eat straight away, or wrap in sandwich paper for later.
Hint: Use a serrated knife to cut the baguette cleanly without crushing it - it makes for better layering and tidier slices.
