Ingredients
Scale
Miso Butter
- 100g softened butter
- 2 tbsp white miso
- 2 tbsp light soy sauce
- 1 large garlic clove, grated
Burger Components
- 4 large portobello mushrooms, stalks removed
- 1 large red onion, cut into 4 thick slices
- 250g block halloumi, cut into 8 thick slices
- 4 burger buns, split
- 2 tomatoes, sliced
- 4 handfuls of rocket or other peppery leaves
- Burger sauce of your choice, to serve
Instructions
- Make the miso butter: In a small bowl, beat together the softened butter, white miso, light soy sauce, and grated garlic until well combined. Set aside for later use.
- Prepare the barbecue: Light your barbecue and wait until the coals are covered with ash. Arrange the coals to create two heat zones—one hotter side for direct grilling and a cooler side to keep food warm.
- Grill mushrooms and onions: Brush the portobello mushrooms and red onion slices generously with some of the prepared miso butter. Place them over the hotter side of the grill and cook for about 10 minutes, turning and basting frequently. Use a spatula when flipping the onions to keep the slices intact. Once charred and softened, move them to the cooler side to keep warm, continuing to baste occasionally.
- Grill the halloumi: Place the halloumi slices directly on the grill over the hot zone. Grill until the cheese is browned and lightly charred on each side, 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 grill until golden and slightly crisp.
- Assemble the burgers: On the toasted buns, layer the grilled mushrooms, onions, charred halloumi, sliced tomatoes, and rocket leaves. Add burger sauce to taste, then top with the bun lids. Serve immediately and enjoy!
Notes
- You can substitute rocket with arugula or other leafy greens for a peppery bite.
- Adjust the amount of miso butter to taste or prepare extra for basting.
- Use a spatula carefully when flipping onions to prevent them from falling apart.
- For a gluten-free version, use gluten-free burger buns.
- Halloumi can be substituted with paneer or firm tofu if desired.
