Equipment

  • Mixing bowl
  • Grill or barbecue
  • Spatula
  • Basting brush
  • Knife and cutting board
  • Plates for assembly

Ingredients
  

For the Miso Butter:

  • 3 tablespoons unsalted butter softened
  • 1 tablespoon white miso paste
  • 1 teaspoon soy sauce
  • 1/2 teaspoon sesame oil

For the Burgers:

  • 4 large portobello mushrooms cleaned and stems removed
  • 2 large onions sliced into thick rounds (keep slices intact)
  • 200 g 7oz halloumi, sliced
  • 4 burger buns halved
  • 2 large tomatoes sliced
  • A handful of rocket arugula
  • Burger sauce or your favorite condiment

Instructions
 

  • Prepare the Miso Butter: In a small bowl, beat together the butter, miso paste, soy sauce, and sesame oil until smooth. Set aside.
  • Prepare the Grill: Light the barbecue and allow the coals to turn ashen. Push more coals to one side to create two heat zones: a hot side for direct grilling and a cooler side for keeping cooked items warm.
  • Grill the Vegetables: Brush the mushrooms and onion slices generously with the miso butter. Position the Vegetables on the hot side of the grill. Cook for about 10 minutes, turning and basting occasionally with more miso butter. Use a spatula to carefully flip the onions to avoid them separating into rings. Once the vegetables are charred and softened, move them to the cooler side of the grill to keep warm. Continue basting occasionally.
  • Grill the Halloumi: Place the halloumi slices directly on the hot side of the grill. Cook until browned and lightly charred, about 2-3 minutes per side.
  • Toast the Buns: Brush the cut sides of the burger buns with the remaining miso butter. Toast them on the hot side of the grill until golden and slightly crisp.
  • Assemble the Burgers: Spread a layer of burger sauce or your favorite condiment on the bottom half of each bun. Layer with grilled mushrooms, onions, halloumi, tomato slices, and rocket. Add the other half of the bun on top.
  • Serve: Serve immediately while warm with additional sides like grilled corn, coleslaw, or fries if desired.
  • Enjoy this umami-packed burger 🍔 that’s bursting with smoky, savory, and creamy flavors! Let me know if you’d like pairing suggestions or additional customizations

Notes

  • Store leftover halloumi in an airtight container in the fridge for up to 3 days. For the best results, reheat it on a non-stick pan or grill to regain its texture and flavor.
  • Experiment with a variety of toppings to make this burger uniquely yours. Avocado slices can add creaminess, while caramelized onions bring a subtle sweetness. If you enjoy a bit of heat, consider spicy sauces like sriracha mayo or a zesty chili relish. The combination of these toppings can elevate the burger to suit your taste preferences.
  • To avoid sticking, always ensure the grill is well-oiled before cooking. Using a high-smoke point oil like vegetable or canola oil works best. For added convenience, you can also use grill mats or foil to keep the ingredients intact while still achieving that smoky grilled flavor.
