Swiss Mushroom Burgers
Description
This recipe uses mushrooms at least 20% larger than the bun, brushed with a flavorful garlic butter mixture, and roasted at high temperature until tender and juicy. After roasting, a slice of Swiss cheese melts atop the mushrooms. Meanwhile, onions are cut into rings and sautéed with olive oil, salt, and pepper until softened and flavorful. A pink sauce made from mayonnaise mixed with ketchup and sriracha adds a tangy, mildly spicy element. The buns are lightly toasted to add texture. Assembly involves layering pink sauce, fresh lettuce leaves, sliced tomato, the cheesy mushroom, and onions. This creates a vegetarian burger that offers rich umami flavors from the mushrooms combined with creamy, spicy, and fresh textures.
The recipe notes suggest adaptations for smaller mushrooms by slicing and cooking in batches. Additional burger toppings like avocado, bacon, fried egg, or beetroot can be added as preferred. Leftover garlic butter and juices can be mopped up with the bun for added taste.

Instructions
- Preheat oven to 220°C/450°F (200°F fan).
- Garlic butter: Place butter, garlic, salt and pepper in a heatproof jug. Microwave to melt butter, then stir.
- Brush with butter: Brush the mushroom cap with butter (smooth side), then place on a tray gills side up (ie stalk facing up). Brush remaining butter onto the rims and gills, being sure to scrape up all the garlic in the jug.
- Olive oil: Drizzle with olive oil.
- Roast 25 minutes, then flip mushrooms. Brush with tay juices, roast a further 10 minutes or until the centre of the mushrooms are tender. {Meanwhile, cook onion, mix Sauce)
- Top with cheese: Place a slice of cheese on each mushroom, return to oven for 3 minutes just to melt the cheese.
- Toast buns: Place split buns in the oven at the same time - to lightly toast.
Assemble burgers
- Spread base of bun with a dollop of Pink Sauce. Top with lettuce, then tomato, then mushroom, then onion. Spread lid with a lesser smear of Pink Sauce, then place on burger. Devour!
Pink Sauce
- Mix together, use per recipe.
Onion
- Heat oil in a large skillet over high heat. Cook onion for 5 to 7 minutes until tinged with gold and floppy. Season with a pinch of salt and pepper.
Notes
- Choose mushrooms about 15% larger than the bun; or use multiple mushrooms per burger if smaller.
- If smaller mushrooms are used (button or cremini), slice and cook in batches with butter and garlic before assembling.
- Additional toppings like avocado, beetroot, fried egg, bacon, or BBQ vegetables can enhance the burger.
- Some garlic butter remains on the tray after roasting; use the bun to soak up these flavorful juices.
