This dish features tender zucchini, earthy mushrooms, and sweet onions, all sautéed to perfection! It’s colorful, healthy, and super easy to make.
It’s great as a side or over rice for a simple meal. I love how the flavors blend together, it’s like a veggie party in my pan! 🎉
Key Ingredients & Substitutions
Zucchini: Fresh, firm zucchini is perfect for this dish. It adds a nice crunch! If zucchini isn’t available, yellow squash is a great substitute with a similar texture and flavor.
Mushrooms: I love using cremini for their deeper flavor, but button mushrooms work just as well. If you want to get fancy, try shiitake or portobello for a different taste.
Onion: Yellow onions are perfect for sautéing. They’re sweet and mellow but you can replace them with red onions for a sharper flavor or shallots for a subtle sweetness.
Olive Oil vs Butter: Olive oil gives a fruity flavor, while butter adds richness. You can combine both for the best of both worlds! For dairy-free eaters, stick with olive oil.
Garlic: While optional, I find garlic really boosts the flavor profile. If you’re not a garlic fan, you can skip it or use garlic powder.
How Can I Get Perfectly Sautéed Veggies?
Sautéing veggies can be tricky, but a few tips will help you achieve that delicious, tender-crisp texture.
- Make sure your skillet is hot before adding oil. This keeps veggies from steaming instead of sautéing.
- Don’t overcrowd the pan. Cook in batches if needed, so each veggie gets enough heat.
- Stir gently but frequently. This allows everything to cook evenly and prevents burning.
- Season as you go! A little salt enhances the veggies’ natural flavors beautifully.

Step-by-Step Instructions:
1. Heating Your Pan:
Start by heating the olive oil or butter in a large skillet over medium heat. Make sure the pan is hot enough before adding the vegetables—this helps them sauté and not steam!
2. Sautéing the Onions:
Once the oil is heated, add the sliced onions to the pan. Sauté them for about 3-4 minutes, stirring occasionally, until they become soft and start to look translucent. This is where the flavors start to develop!
3. Adding the Mushrooms:
Next, add the sliced mushrooms to the skillet. Stir occasionally and cook for around 5 minutes until the mushrooms release their moisture and begin to brown. The aroma will be amazing!
4. Mixing in the Garlic:
If you’re using garlic, now’s the time to stir it in! Cook for about 30 seconds, just until it becomes fragrant. Be careful not to burn it!
5. Adding the Zucchini:
Now it’s time to add the sliced zucchini to the skillet. Season everything with salt and pepper to taste. Sauté for an additional 5-7 minutes, stirring occasionally, until the zucchini is tender but still has a slight crunch—just perfect!
6. Final Touches:
Give everything a taste and adjust the seasoning if needed. If you love fresh herbs, now’s a great time to add a bit more for flavor!
7. Garnishing and Serving:
Remove the skillet from heat and sprinkle the sautéed veggies with fresh chives. This adds a wonderful burst of color and flavor. Serve warm as a delicious side dish or spoon it over a bed of grains for a light meal.
Enjoy your colorful and tasty sautéed zucchini, mushrooms, and onions! 😊
