Take your toastie game to a new level. Sweet caramelised onions and perfectly melted cheese meet the rich flavour of Abbott's Bakery Sourdough Rye for a French Onion Toastie worth savouring.
Serves 2
Ingredients
4 slices Abbott's Bakery Sourdough Rye
30g unsalted butter
3 brown onions, thinly sliced
2 sprigs thyme, leaves picked
80ml beef stock
Black pepper
1 tbsp Dijon mustard
100g gruyère, grated
15g unsalted butter, softened
Mixed salad leaves, to serve
Method
Melt the butter in a large frying pan over medium-low heat. Add the onions and thyme. Cook, stirring occasionally, for 40–45 minutes until deeply golden, soft and jammy.
Add the beef stock and cook for a further 5 minutes until reduced and glossy. Season with black pepper.
Spread the Dijon mustard over one side of each slice of bread.
Divide half the gruyère between two slices of bread. Top with the caramelised onions and remaining gruyère, then sandwich with the remaining slices.
Butter the outside of each sandwich.
Cook in a frying pan over medium-low heat for 3–4 minutes per side until deeply golden and crisp and the cheese has melted.
Slice in half and serve immediately with the mixed salad leaves.
