Instructions

Mushrooms and buns

  1. Step 1: Preheat the oven to 220°C/450°F (200°F fan).

  2. Step 2: Put the butter, garlic, salt and pepper in a heatproof jug. Microwave until the butter is melted, then stir.

  3. Step 3: Brush the smooth side of each mushroom cap with the garlic butter. Put the mushrooms on a tray, gill side up with the stalk facing up. Brush the remaining butter over the rims and gills, scraping all the garlic out of the jug.

    A collage shows garlic butter being mixed and brushed on mushrooms, then roasted mushrooms, melted cheese and assembled burgers.
  4. Step 4: Drizzle the mushrooms with olive oil.

  5. Step 5: Roast for 25 minutes, then flip the mushrooms. Baste them with the pan juices and roast for a further 10 minutes, or until the centres are tender. While they roast, prepare the onion and pink sauce.

    A roasted mushroom cap rests on a baking tray with its browned gills facing up.
  6. Step 6: Put a slice of cheese on each mushroom and return the tray to the oven for 3 minutes, just until the cheese melts.

  7. Step 7: Put the split buns in the oven at the same time to lightly toast.

Assemble the burgers

  1. Step 8: Spread a dollop of pink sauce on the base of each bun. Add lettuce, tomato, mushroom and onion. Spread a smaller amount of pink sauce on each bun top, place it on the burger and serve.

Pink sauce

  1. Step 9: Mix the mayonnaise, ketchup and Sriracha together, then use the sauce for the burgers.

Onion

  1. Step 10: Heat the oil in a large skillet over high heat. Cook the onion for 5 to 7 minutes, until tinged with gold and softened. Season with a pinch of salt and pepper.

Notes

Options

For smaller button or cremini mushrooms, the recipe notes suggest slicing 200 g per burger about 0.5 cm thick and cooking them in two batches in a large skillet with 60 g butter and 2 minced garlic cloves. Cook over high heat until golden, gather into a mound for each burger, top with cheese and melt under the grill or covered with a lid.

The recipe also lists avocado as an alternative to the pink sauce, and beetroot, a fried egg, bacon, pineapple or BBQ-marinated vegetables as burger additions. Other sauce options include ketchup, Sriracha or another chilli sauce, plain mayonnaise, aioli or mustard.
