Sauteed Zucchini Mushrooms and Onions: A Healthy and Flavorful Side Dish

Growing up, my mom had a way of turning the simplest ingredients into the most flavorful dishes. One of my favorite childhood memories is watching her sauté a big batch of zucchini, mushrooms, and onions on the stove. The aroma would fill the whole house, and I’d come running to the kitchen, eager to be the first one to dig in. There was just something so comforting and satisfying about that combination of tender zucchini, earthy mushrooms, and sweet onions, all simmered to perfection in a garlicky, herby sauce. To this day, sauteed zucchini mushrooms and onions remain one of my go-to side dishes, and I’ve even started making it as a main course on busy weeknights. It’s just so darn delicious and versatile!

Why This Sauteed Zucchini Mushrooms and Onions Recipe Will Become Your Go-To

The Secret Behind Perfect Sauteed Zucchini Mushrooms and Onions

The secret to making the best sauteed zucchini mushrooms and onions lies in a few simple techniques. First, you’ve got to make sure you cut everything into uniform, bite-sized pieces so they cook evenly. And instead of sautéing everything together at once, I like to cook the mushrooms and onions first to build up that delicious caramelized flavor before adding the zucchini. That way, the zucchini doesn’t get overcooked and watery. Finally, a splash of white wine or broth and a handful of fresh herbs at the end really takes this dish to the next level. Trust me, once you try this recipe, it’s going to be on regular rotation in your household!

Essential Ingredients You’ll Need

  • Zucchini – Look for firm, unblemished zucchini and slice it into half-moons about 1/2 inch thick.
  • Mushrooms – I prefer to use a mix of cremini and shiitake mushrooms, but any variety will work.
  • Onions – Yellow or white onions are best for this dish, diced into 1/2 inch pieces.
  • Garlic – Freshly minced garlic adds tons of flavor.
  • Olive oil – A good quality extra virgin olive oil is the perfect cooking fat.
  • White wine or broth – Just a splash provides moisture and brightens the flavors.
  • Herbs – Fresh thyme, oregano, or basil work wonderfully.
  • Salt and pepper – To taste.

Step-by-Step Sauteed Zucchini Mushrooms and Onions Instructions

Preparing Your Sauteed Zucchini Mushrooms and Onions

This sauteed zucchini mushrooms and onions recipe comes together quickly, in about 30 minutes from start to finish. You’ll need a large skillet or wok and a few basic kitchen tools. Let’s get started!

1- Begin by cleaning and prepping all your ingredients. Slice the zucchini into half-moons, dice the onions, and slice or quarter the mushrooms.
2- Heat a large skillet or wok over medium-high heat and add a few tablespoons of olive oil. Once the oil is shimmering, add the onions and mushrooms. Sauté for 5-7 minutes, stirring frequently, until the vegetables are starting to brown.
3- Add the minced garlic and continue cooking for 1-2 minutes, until fragrant.
4- Next, add the sliced zucchini to the pan. Sauté for 5-7 more minutes, or until the zucchini is tender-crisp. You’ll want to keep a close eye on it to prevent overcooking.
5- Deglaze the pan with a splash of white wine or broth, scraping up any browned bits from the bottom. This adds tons of flavor.
6- Finally, stir in the fresh herbs and season generously with salt and pepper. Serve your sauteed zucchini mushrooms and onions immediately, while hot and fresh!

Pro Tips for Success

The key to perfectly cooked sauteed zucchini mushrooms and onions is to avoid overcrowding the pan and not to overstir. You want the vegetables to have enough room to sear and caramelize. Also, be mindful of the cooking time on the zucchini – it can go from crisp-tender to mushy in a matter of minutes. And don’t be afraid to adjust the seasoning at the end to suit your personal taste preferences.
