Sautéed Zucchini with Mushrooms and Onions Recipe

This Sautéed Zucchini recipe is a flavorful side dish that combines tender zucchini with savory mushrooms and onions, all seasoned with Italian spices. It’s simple to make and pairs wonderfully with a variety of main courses. Here’s how to prepare it:


  • 1 tablespoon olive oil
  • 2 tablespoons butter
  • 1 medium yellow onion, chopped
  • 8 ounces white button mushrooms, stems trimmed and quartered
  • 3 medium zucchini, cut into bite-size chunks
  • 2 cloves garlic, minced
  • 1 teaspoon Italian seasoning
  • ¼ teaspoon red pepper flakes (adjust to taste)
  • Kosher salt and fresh ground black pepper to taste


  1. Heat Oil and Butter:
    • In a large skillet over medium heat, heat the olive oil and butter until the butter is melted. This combination helps in browning and adds a rich flavor to the vegetables.
  2. Sauté Onions and Mushrooms:
    • Add the chopped onion to the skillet. Cook, stirring occasionally, until the onions begin to soften and become translucent, about 4-5 minutes.
    • Add the quartered mushrooms to the skillet. Continue to cook, stirring occasionally, until the mushrooms are browned and their moisture has evaporated, approximately 5-7 minutes.
  3. Add Zucchini:
    • Incorporate the zucchini chunks into the skillet. Stir to mix with the onions and mushrooms. Cook for about 7-10 minutes, or until the zucchini is tender but still holds its shape.
  4. Season the Vegetables:
    • Stir in the minced garlic, Italian seasoning, and red pepper flakes. Cook for another 1-2 minutes, until the garlic is fragrant.
    • Season with kosher salt and fresh ground black pepper to taste. Adjust the seasoning according to your preferences.
  5. Serve:
    • Once the vegetables are cooked and well-seasoned, remove from heat. Serve the sautéed zucchini immediately while it’s still hot and flavorful.


  • Variations: Feel free to add other vegetables like bell peppers or eggplant for more variety and color.
  • Serving Suggestions: This dish goes well with grilled chicken, fish, or steak. It can also be a great addition to pasta or served over a bed of rice or quinoa.
  • Make it Vegan: To make this recipe vegan, simply substitute the butter with additional olive oil or a plant-based butter alternative.
