Ingredients
Method
- Rinse the zucchinis and mushrooms under cold water, then cut the zucchinis into half-moon shapes while slicing mushrooms and finely slicing the onion. Mince the garlic finely.
- Heat a large skillet on medium flame and pour in the olive oil, letting it warm up for about a minute.
- Toss in the sliced onion and cook, stirring occasionally, until it softens and turns translucent, around 3 minutes.
- Add the garlic and mushrooms to the pan, continue cooking for 3 to 4 minutes until mushrooms soften and release their juices, stirring now and then.
- Introduce the zucchini slices and season with salt, black pepper, and sprinkle thyme if using. Keep stirring frequently while cooking for another 3 to 5 minutes until the zucchini becomes tender yet maintains some firmness.
- Taste and adjust the seasoning with a pinch more salt or pepper as preferred.
- Remove the skillet from heat, transfer the vegetables onto a serving dish, sprinkle with fresh chopped parsley if desired, and serve immediately while warm.
