Step-by-Step Instructions

Step 1: Prep the Vegetables

Wash and slice the zucchini and mushrooms. Mince the garlic and juice the lemon.

Tip: Don’t over-slice the zucchini—thicker pieces hold up better during cooking.

Step 2: Heat the Pan

Place a large skillet over medium-high heat and add the olive oil. Once hot, add the zucchini slices and cook for 3–4 minutes per side , until lightly browned and slightly tender. Remove from the pan and set aside.

Step 3: Sauté the Mushrooms

In the same skillet, add a bit more oil if needed. Add the sliced mushrooms and cook for 5–6 minutes , stirring occasionally, until they release their moisture and begin to brown.

Add the minced garlic and red pepper flakes (if using), and sauté for another 1–2 minutes until fragrant.

Step 4: Combine Everything

Return the cooked zucchini to the skillet with the mushrooms. Stir well to combine.

Cook together for an additional 2–3 minutes , allowing the flavors to meld.

Step 5: Finish with Lemon and Herbs

Squeeze in the fresh lemon juice and season with salt and pepper to taste.

Toss everything together and remove from heat.

Garnish with chopped fresh parsley or basil before serving.
