Portobello mushrooms are brilliant carriers for bold seasoning, which makes them a natural partner for Steak Spice. They turn juicy and deeply savoury on the grill while keeping a satisfying, substantial bite.

Roasted pepper adds sweetness and blue cheese adds tang, creating a vegetarian burger that feels like the main event rather than a compromise.

🧾 Ingredients

• 4 large portobello mushrooms
• 1½ tbsp Steak Spice
• 2 tbsp olive oil
• 2 roasted red peppers from a jar, drained
• 100g blue cheese, crumbled
• 4 seeded burger buns
• 2 handfuls rocket
• 4 tbsp natural yoghurt or mayonnaise
• 1 tsp lemon juice

🍴 Instructions

1. Remove the mushroom stalks and gently wipe the caps clean.
2. Mix the Steak Spice with the olive oil and brush over both sides of each mushroom.
3. Cook on a medium-hot barbecue or griddle, gill-side down first, for 4–5 minutes per side.
4. Add the blue cheese to the gill side for the final 2 minutes and cover briefly so it softens.
5. Mix the yoghurt or mayonnaise with the lemon juice. Lightly toast the buns.
6. Layer the rocket, mushrooms, roasted pepper and lemon dressing in the buns. Serve immediately.

💛 Why This Recipe Works

Portobello mushrooms absorb the seasoned oil and develop dark, savoury edges. Their gills also create a natural pocket for the melting blue cheese.
