Success tips on making mushroom cheese toastie
Sauté onions until soft.
Sautéing onions until golden, soft, and translucent helps to build up the flavours in the toastie. They release natural sugars as they cook, adding a subtle sweetness that balances the umami of mushrooms and richness of cheese.
Taste and adjust.
When sautéing mushrooms and onions, be sure to do a taste test as you add in seasonings. Adjust the amounts to suit your taste preference.
Cook the toastie low and slow.
Toast the sandwich with some butter in the pan over medium-low heat to melt cheese fully without burning the bread. Use a spatula, a heavy pan, or sandwich press to press down lightly to toast the bread and melt the cheese faster.
Crispy, savoury, and satisfying, this mushroom cheese toastie is the ultimate comfort food to make that’s ready in minutes. The crunch through the golden, buttery bread gives way to an umami-packed centre with stretchy cheese clinging onto garlicky mushrooms and sweet caramelised onions. Whether it’s for breakfast, lunch, or mid-day snack, this toastie offers pure comfort in every bite.
