Caramelized Onion Bread
Deeply savoury caramelised onion butter, whipped smooth and spread thick on toasted bread.
Ingredients
- 115g butter, softened to room temperature
- 2 small onions, any colour, very thinly sliced
- 1 tbsp vegetable oil
- 1/2 tsp fine salt or sea salt
- large pinch of MSG (optional)
- 4 thick slices of bread, of your choice
Instructions
- Take the butter out of the fridge and let it come to room temperature until it offers no resistance when poked.
- Slice the onions as thinly as you can.
- Heat the oil in a large pan over the lowest heat your stove will go.
- Add the onions and salt, and stir to coat the onions in the oil.
- Leave the onions to caramelise slowly for at least an hour without increasing the heat — turning the heat up will fry and crisp them instead of caramelising them.
- Once caramelised, scrape the onions out of the pan and let them cool.
- Blitz the cooled onions with the butter and MSG in a food processor or with an immersion blender until smooth, with just a few flecks of onion remaining.
- Lightly toast a slice of bread, spread generously with the onion butter, then return to the toaster oven, grill or air fryer until the onion flecks catch a little colour at the tips.
- Eat immediately.
