Method

Mushroom Preparation

  1. 1

    Prepare the Mushrooms

    Clean the portobello mushrooms with a damp cloth to remove any debris. Remove the stems carefully.

  2. 2

    Marinate the Mushrooms

    In a bowl, mix olive oil, salt, and black pepper. Brush the mixture on the mushrooms, coating them evenly.

  3. 3

    Grill the Mushrooms

    Preheat a grill or grill pan over medium heat. Grill the mushrooms for 4-5 minutes on each side until tender and slightly charred.

Balsamic Caramelized Onions

  1. 4

    Slice the Onions

    Peel and thinly slice the yellow onions.

  2. 5

    Cook the Onions

    In a skillet over medium heat, combine butter and olive oil. Add the sliced onions, salt, and sugar. Cook for about 10 minutes, stirring occasionally until they become soft.

  3. 6

    Add Balsamic Vinegar

    Stir in the balsamic vinegar and continue cooking for another 10-15 minutes until the onions are deeply caramelized. Remove from heat.

Roasted Garlic Aioli

  1. 7

    Roast the Garlic

    Preheat the oven to 400°F (200°C). Wrap the garlic cloves in foil and roast for 20-25 minutes until soft.

    Prepare the Aioli

    Once the garlic is cool, squeeze the cloves into a bowl. Add mayonnaise, lemon juice, and salt, and mix until smooth.
