Step-by-Step Instructions – How to Make Easy Sautéed Zucchini, Mushrooms, and Onions
-
Heat the pan
First, place a large skillet over medium-high heat and add the olive oil. Allow it to warm until shimmering but not smoking. -
Sauté the onions
Next, add the sliced onions and cook for 3–4 minutes, stirring occasionally, until they soften and begin to turn lightly golden. This builds the sweet flavor base. -
Add mushrooms
Then, add the mushrooms to the pan. Spread them out evenly and allow them to cook undisturbed for 2 minutes so they release moisture and develop color. -
Deglaze gently
Meanwhile, stir the mushrooms and onions together. If the pan looks dry, add a splash of water or broth to loosen the browned bits. -
Incorporate zucchini
Next, add the zucchini slices along with garlic, salt, and black pepper. Toss gently to coat everything evenly. -
Sauté until tender
Cook for 4–5 minutes, stirring occasionally, until the zucchini is just tender but still holds its shape. -
Finish and adjust
Finally, add butter or a small splash of soy sauce if using. Taste and adjust seasoning, then remove from heat and garnish with fresh herbs.
