If you often have the main dish planned but struggle with sides, this recipe is here to help. It’s quick, naturally gluten-free, and flexible — a great option when you want a straightforward vegetable side without fuss.
Sautéed mushrooms and zucchini are beginner-friendly and adapt well to different seasonings. The vegetables themselves are fairly mild, so a little garlic, kosher salt, and freshly ground black pepper are all you need to make them shine. One important tip: cook the mushrooms first to release their moisture before adding the zucchini. That keeps the zucchini from becoming mushy.

How to saute zucchini and mushrooms
- Warm the oil in a large nonstick pan over medium heat and add the garlic, stirring briefly to release its aroma.
- Add the sliced mushrooms and half the kosher salt. Stir to coat, then spread the mushrooms into a single layer and let them cook undisturbed for 6 minutes so they release moisture and brown.
- While the mushrooms cook, slice the zucchini into ¼-inch rounds and cut those rounds in half. Set aside.
- After the first 6 minutes, stir the mushrooms and flip the uncooked side down. Spread them out again and cook another 4 minutes without stirring.
- When the mushrooms have browned, add the zucchini, the remaining kosher salt, and the black pepper. Stir to combine.
- Cook for about 6 more minutes, stirring occasionally, until the zucchini is tender but not mushy. Serve immediately.
Storage and reheating tips
- Storing: Cool and transfer leftovers to an airtight container and refrigerate for 3 to 4 days.
- Reheating in a pan (recommended): Warm a small pan over medium-low heat and sauté the leftovers briefly until heated through; this helps evaporate excess moisture and refresh texture.
- Reheating in a microwave: Heat in 30-second increments until warm. Note: microwave reheating can make the vegetables softer and slightly soggy compared with stovetop reheating.
How do you keep zucchini from getting soggy?
To avoid soggy zucchini, cut it no thinner than ¼ inch and add it to the pan only after the mushrooms have released their moisture and started to brown. Zucchini cooks quickly and will become mushy if added too early.
What is a good size for zucchini?
Small to medium zucchini (about 5 to 6 ounces each) work best for even cooking. If you only have a large zucchini, slice to the same ¼-inch thickness and cut each round into quarters so pieces cook through evenly.
Recipe tips and substitutions
- When buying pre-sliced mushrooms, note thickness: thinner slices cook faster, thicker slices need more time.
- Baby bella mushrooms are used here, but white button, shiitake, oyster, or other common varieties all work.
- For heat, add cayenne or red pepper flakes with the zucchini.
- You can swap yellow summer squash for zucchini. Avoid hard-skinned winter squashes like butternut or acorn for this quick method.
- Add other quick-cooking vegetables such as sliced onion or bell pepper — add them after the first mushrooms’ cook time.
- Finish with fresh herbs, a squeeze of lemon, nutritional yeast, or grated Parmesan (if not following dairy-free or other restrictive diets).
Serving suggestions
This versatile side pairs well with a range of mains. Try it alongside grilled shrimp, a simply seasoned grilled chicken breast, meatloaf, or as part of a vegetable-forward plate with grains or eggs.

20 Minute Sautéed Zucchini & Mushrooms
Equipment
-
A large nonstick pan
-
Measuring spoons
-
A pair of tongs (or other utensil)
-
A sharp knife
-
A cutting board
Ingredients
- 8 oz sliced mushrooms
- 2 small/medium zucchini between ⅝ and ¾ lb
- 2 cloves garlic pressed or minced
- 1 tbsp olive oil
- ½ tsp kosher salt divided
- ⅛ tsp fresh ground black pepper or more if desired
Instructions
-
Place a large nonstick pan over medium heat. Add the oil and warm for a minute, then add the pressed garlic and stir.
-
Pour in the sliced mushrooms and use tongs to coat them with garlic and oil. Add ¼ tsp kosher salt and stir. Arrange the mushrooms in a single layer and cook for 6 minutes undisturbed.
-
While the mushrooms cook, wash and dry the zucchini. Trim the ends, slice into ¼-inch rounds, then cut rounds in half and set aside.
-
After 6 minutes, stir and flip the mushrooms so uncooked sides face down. Spread into a single layer and cook undisturbed for 4 more minutes.
-
Add the zucchini, black pepper, and remaining ¼ tsp kosher salt. Stir to combine, spread vegetables in the pan, and cook for about 6 minutes, stirring occasionally.
-
Remove from heat when vegetables are tender but still hold their shape. Serve immediately.
Notes
- Pre-sliced mushroom thickness varies; adjust cook time slightly if slices are very thin or thick.
- Use any common mushroom variety: baby bella, white button, shiitake, or oyster.
- For extra heat, add a pinch of cayenne or red pepper flakes with the zucchini.
- Yellow summer squash can be substituted for zucchini; avoid using firm winter squashes for this quick sauté.
