Garlic aioli:

  • 1 large clove garlic, finely grated
  • 125 ml high-quality French-style creamy mayonnaise
  • 1 Tbsp lemon juice
  • Pinch of sea salt

Zucchini chips:

  • 4 large zucchini / baby marrow
  • 3 Tbsp Parmesan cheese, finely grated
  • 1 tsp garlic powder

Portabello steaks:

  • 4 cloves garlic
  • 1 cup mixed fresh herbs (parsley, oregano, mint, basil, etc.)
  • 160 ml olive oil
  • 1 tsp lemon zest
  • 2 Tbsp fresh lemon juice
  • 1 tsp chilli flakes
  • Pinch of sea salt
  • 4 large portobello mushroom steaks


How to make garlic aioli:

  1. Combine all ingredients in a small bowl and whisk well.
  2. Season to taste and set aside in the fridge until serving.

How to make zucchini chips:

  1. Cut the zucchini into very thin rounds using a mandoline or very sharp knife.
  2. Toss in a bowl with a good pinch of salt.
  3. Spread the slices out in a single layer on a clean dishcloth for 5 minutes.
  4. Take another dishcloth, cover them, and press gently to extract as much water out of the zucchini as possible.
  5. Heat an air fryer to 180˚C.
  6. Coat the air fryer basket or tray with cooking/olive oil spray.
  7. Add enough zucchini slices to sit in a single layer.
  8. Sprinkle zucchini with about 1 Tbsp of the grated Parmesan cheese and a little garlic powder.
  9. Air-fry until golden-brown, 7 to 8 minutes.
  10. Check the chips halfway through. Small chips may brown and crisp before larger ones.
  11. Transfer the chips to a serving plate. Repeat air frying the remaining zucchini.

How to make portabello steaks:

  1. Preheat a grill on medium-high heat.
  2. Combine all the ingredients, except the mushrooms, in a small jug.
  3. Blitz with a stick blender.
  4. Place mushroom steaks on the grill and brush them liberally with the herby garlic oil.
  5. Grill until tender and lightly charred all over, basting while you cook.
  6. Serve mushrooms hot off the grill with a pile of zucchini chips, a good dollop of aioli, and some more herb oil on the side.
  7. Enjoy!
