Step-by-Step Zucchini with Mushrooms and Onions
1. Wash and slice the zucchini, mushrooms, and onion.
Begin by rinsing your 2 medium zucchini, 8 ounces of mushrooms, and 1 medium onion under cool water. Slice them into even pieces to ensure uniform cooking.
2. Heat olive oil in a skillet over medium heat.
Pour 2 tablespoons of olive oil into a large skillet. Allow it to warm for about a minute until it shimmers, creating a perfect base for sautéing.
3. Add the sliced onions and sauté for 3-4 minutes until translucent.
Toss in the sliced onion and stir occasionally. Watch for the color change; they should turn soft and translucent, filling your kitchen with a lovely aroma.
4. Add the sliced mushrooms and cook for another 5 minutes until they start to brown.
Mix in the sliced mushrooms, stirring gently. Cook for about 5 minutes until they begin to brown beautifully, enhancing their rich flavor.
5. Stir in the zucchini and garlic, cooking for an additional 5-7 minutes until the zucchini is tender.
Now add those fresh zucchini slices along with 1 teaspoon of minced garlic. Sauté everything together for 5-7 minutes until the zucchini softens but still retains a slight bite.

What if my mushrooms start to release too much water while cooking?
Don’t worry! If your mushrooms release excess moisture, simply continue cooking them over medium-high heat. This helps evaporate the liquid, allowing them to brown nicely without becoming soggy. Aim for that golden-brown color after about 5 minutes of cooking.
