Gluten-Free Toasted Sandwiches – the perfect lunch choice!
A decent gluten-free toasted sandwich is hard to come by, but these focaccia sandwiches really raise the game for are a very satisfying lunch or snack.
Of course, you first need to start off with either some store-bought or homemade gluten-free focaccia bread that can be sliced open to then top with your favourite fillings. I have video instructions to make gluten-free focaccia bread, which, by the way, is a very easy recipe!
Sandwich Fillings
Stuck on filling ideas? I have listed four suggested fillings in the recipe card, of which two are vegetarian fillings.
How are the sandwiches toasted?
I have given cooking instruction for three different methods:
- Panini maker (my 1st choice)
- Griddle pan
- Oven
Can these be made in advance?
Ready-assembled untoasted focaccia sandwiches are a make-ahead friendly snack to have ready in the fridge to toast when the time comes for a decent sandwich lunch or snack.
Make sure to wrap each sandwich tightly in plastic. This will keep them compact and moulded for toasting, even after one day or so.

Enjoy creating your own filling together with the family, especially with children who will take more interest in ingredients and hopefully more vegetables to add!

TOASTING THE FOCACCIA SANDWICH

- Add two assembled focaccia sandwiches at a time. Using a wide spatula, press down the tops of the focaccia often for 5 minutes.
- Carefully turn the focaccia sandwich over and repeat pressing down for another 5 minutes, until the focaccia bread looks toasted and the fillings have melted or softened.
Oven
- Preheat the oven to 180°C/350°F.
- Wrap each focaccia sandwich in foil and bake for 15 minutes directly on the oven rack.
- Remove the foil and return the focaccia sandwiches on a baking tray to bake a further 5 minutes, or until the focaccia bread looks toasted and the fillings have melted or softened.
Notes
- Assembled focaccia sandwiches keep for 2 days chilled
- Not suitable to freeze
