A Quick & Easy Veggie Side

Sometimes the best way to prepare fresh veggies is a simple sauté. I love doing this with zucchini, especially, because it cooks up quickly. In this dish, we’ll be adding diced onion and fresh whole mushrooms, too, for a savory veggie side that you HAVE TO try.

To finish off the flavors, I use a bit of veggie broth and herbs, adding the perfect ending touch to make this simply delicious vegetarian side dish.

This is a side you could serve any night of the week, but it’s also great to whip up for a special occasion. I think that onions and oregano are classic flavors for holiday meals, but also perfect for light summer dinners. Plus, it all comes together super easily in just one skillet!

What You’ll Need

This fresh and zesty side dish is easy to make. Plus, it’s full of natural, healthy ingredients!

  • Olive Oil: To sauté the veggies, you’ll need a tablespoon of olive oil or your other preferred high-heat oil.
  • Zucchini: Cut two zucchini into thin, half-moon slices.
  • Salt & Pepper: To taste.
  • Butter: Have on hand three tablespoons of butter, divided.
  • Onion: You’ll need ½ a cup of finely diced onion to sauté along with the mushrooms. White onions, yellow onions and sweet onions all work well in this dish!
  • Mushrooms: Gently clean a pound of small button mushrooms. You can also use your favorite sliced mushrooms, if you prefer, but just make sure the mushrooms are all cleaned well so to avoid that strong earthy/dirt taste, ya know what I mean? 😬
  • Broth: You can use veggie broth, chicken broth or beef broth.
  • Fresh or Dried Herbs: Earthy herbs taste great with zucchini and mushrooms.
  • Garlic: You’ll need three to four cloves of fresh garlic, minced. The garlicky-er, the better, if you ask me. 🧄 ❤️
  • Chopped Fresh Parsley: For garnish.

How to Make Skillet Zucchini and Mushrooms

  3. Return Zucchini & Finish Dish: Return the cooked zucchini to the skillet and sauté for 1 minute, or until heated through. Pour in the vegetable broth and cook for 2 minutes. Taste for salt and pepper and adjust as needed.

Tips for Making Sautéed Zucchini and Mushrooms

These handy tips will help you customize this recipe for your family. Enjoy!

  • Squash Substitution: If you’d like, you can swap yellow summer squash for some or all of the zucchini. They have an almost identical texture and flavor, with an attractive yellow color.
  • Onion Alternatives: This dish is also super tasty with leeks or scallions in place of the diced onion.
  • Au Gratin Option: Make this sauté into a tasty casserole by transferring the finished dish to a baking dish. Top with shredded cheddar and buttered breadcrumbs, and bake for 10 minutes or so at 350°F. It’s DELISH!

  2. Cassie H.

    Listen…if I could give this 10 stars I would. I forgot the onion…didn’t even see the herbs on the list so I only seasoned with salt, pepper and veggie broth…and yet this was so BOMB! My Gawd…absolutely delicious! Added bonus is how quick and easy it was. The grated parmesan was a nice touch. I truly don’t see how someone doesn’t like this recipe. I see me cooking this weekly…no lie! Pinterest is out here saving lives! Thanks for sharing!!!!!

  3. Karen Sternberg

    I’ve made this regularly for years. One of my favorites, can go w/ anything. Inside an Omelette, along side Scrambled Eggs even over pasta. I plan to try it next on sweet potatoes.

    Will try w/ those seasonings, they sound lovely, thanks.

  4. Sarah Doss

    A delicious way to eat zucchini! I followed the comments and cut the zucchini rather thick. I only used enough broth to heat up the vegetables right before we sat down to eat. My husband said, “Let’s make this a staple!” and he normally doesn’t like zucchini. The grated Parmesan is a nice touch.

  5. Kelly

    This was absolutely delish. The combination was perfect together. And it smelled so good before i even served it. I could hardly wait to eat it. Everyone loved it!

  6. Riverlites

    Very good. Practically a no brainer; when the ingredients are so right and the technique is smart (ie, quick with veggies), you can count on a good result. For once, I read comments first so i left zucchini slices a little thicker so I avoided some mushiness (next time, most of the broth goes out too). Flavor will depend mostly on herbs chosen: I had fresh thyme and rosemary but my oregano was in a tube; fresh would have been zingier. PS Don’t let your store sell you giant zucchinis; we want young ones.

  7. Dianne Bennett

    Can you use squash in place of zucchini?? Or even a combo of squash, zucchini and mushrooms usuing same recipe???

  8. Daryl

    Just started a plant based diet and was looking for ideas when I found this. Can not get enough of it. During zucchini season we often joked that you can always tell a person who does not have any friends. They are the ones in the store buying zucchini since the plants produce so much. Now I have to make my garden larger and figure out how to raise mushrooms.


    Delicious dish. I cut the veggies a bit thicker (saw someone mention that here) and they kept a nice firm texture and didn’t get mushy. I wouldn’t change a thing other than that. Served with boneless chicken thighs and a salad.

  10. Traci

    I hate to be a daisy downer but these were just ok. I followed the recipe exactly and they were so mushy I could eat them. I will try them again with some changes. No broth, it’s not necessary and makes them too soupy. Also I will cut the zucchini slices thicker because if they are too thin they get very mushy very quickly. I will also not cook the onions first. They almost disintegrate by the time you finish. Sorry☹️
