Thick-sliced mushrooms browned hard in butter and garlic, piled onto toasted sourdough with melted cheese — an Australian café brunch staple.
The mushroom and garlic toastie is a fixture of Australian café brunch menus, especially in Melbourne and Sydney where the flat white and smashed-avo culture also gave rise to a strong toasted-sandwich tradition. Field or portobello mushrooms are sliced thick and cooked hard in a screaming-hot pan with butter and garlic until they release their liquid and then brown properly in the fat left behind — the difference between a soggy filling and a rich, savory one comes entirely down to not crowding the pan. The mushrooms go onto grilled sourdough with a layer of good melting cheese, usually a tasty cheddar or Swiss, and finished under the grill or in a sandwich press until the cheese pulls when you tear it apart. It's humble pub and café food, built on the same produce-forward, no-fuss approach that defines modern Australian brunch cooking. Home versions skip the fancy plating but keep the technique: brown the mushrooms properly, don't skimp on garlic, and toast the bread until it can hold its structure under a hot, oozing filling.
Serves 2
Heat 2 tbsp butter in a wide pan over high heat. Add mushrooms in a single layer without crowding and cook undisturbed for 3-4 minutes until deeply browned.
If the pan is crowded the mushrooms steam instead of browning — cook in two batches if needed.
Stir in garlic, thyme, salt and pepper and cook 1 more minute until fragrant. Remove from heat.
Butter the outside of each bread slice. Layer cheese and mushrooms between two slices of bread, cheese-side touching the bread for better melting.
Cook in a sandwich press or a pan over medium heat, pressing gently, for 3-4 minutes per side until the bread is golden and cheese is fully melted.
Cut in half, scatter with parsley, and serve immediately while the cheese is still pulling.
Use a well-seasoned cast-iron or heavy pan — it holds heat better and browns mushrooms faster than a thin non-stick.
Wipe mushrooms clean with a damp cloth instead of rinsing; they absorb water and steam rather than sear.
Butter the bread all the way to the edges so the crust toasts evenly under the press.
Add a fried egg on top for a heartier brunch version.
Swap cheddar for gruyère and add a thin layer of Dijon mustard.
Add baby spinach wilted in the same pan for extra greens.
Best eaten immediately — toasted sandwiches turn soggy on standing. If needed, keep the cooked mushroom mixture refrigerated up to 2 days and toast fresh bread to order.
The toasted sandwich is a well-established fixture of Australian café and pub food, growing out of a strong 20th-century sandwich-press culture in Australian home kitchens. The mushroom-and-garlic version rose alongside Australia's café brunch boom from the 1990s onward, when Melbourne in particular became known internationally for elevating simple produce-driven brunch dishes.
Portobello or large field mushrooms hold their texture and give the meatiest bite; button mushrooms work too but release more liquid, so cook them a little longer.
Yes — use a plant-based butter and a good melting vegan cheese; the mushroom technique stays exactly the same.
This usually means the mushrooms weren't cooked long enough to release and evaporate their liquid before assembling — brown them fully and let excess moisture cook off first.
