Equipment

  • large skillet
  • chef’s knife
  • cutting board
  • Spatula

Ingredients
  

  • 2 medium zucchinis, sliced into half-moons
  • 225 g mushrooms (button or cremini), sliced
  • 1 medium onion, thinly sliced
  • 2 tbsp olive oil
  • 2 garlic cloves, minced
  • salt, to taste
  • black pepper, to taste
  • 1 tsp dried thyme (optional)
  • fresh parsley, chopped (optional garnish)

Instructions
 

  • Wash and slice the zucchini into half-moons, slice the mushrooms, thinly slice the onion, and mince the garlic.
  • Heat a large skillet over medium heat. Add the olive oil and heat until shimmering.
  • Add the sliced onions and sauté for about 3 minutes until translucent and lightly caramelized.
  • Stir in the garlic and mushrooms. Cook for 3–4 minutes until mushrooms release moisture and begin to firm.
  • Add the zucchini slices. Season with salt, black pepper, and dried thyme if using. Sauté for 3–5 minutes until tender but not mushy.
  • Remove from heat, transfer to a serving dish, and garnish with fresh parsley if desired. Serve warm.

Notes

Pat vegetables dry before cooking to encourage caramelization. Cook over medium to medium-low heat to prevent sogginess. Let the dish rest briefly off heat so flavors can meld before serving.
