Skillet zucchini and mushrooms make a fresh and healthy side that comes together in one pan with a little butter and olive oil. This is my go-to recipe when I want a quick veggie dish that feels special but requires very little prep.
This dish became part of my regular rotation after a weekend when my garden zucchini seemed to double overnight I made it for friends and everyone asked for the recipe before they left
Ingredients
- Olive oil: One tablespoon helps start the sauté and adds fruity notes Look for a fragrant cold pressed oil
- Butter: Three tablespoons add richness and allow the veggies to caramelize Use high quality unsalted butter if you can
- Zucchini: Two small ones sliced into half moons Choose firm glossy zucchini free of blemishes
- Salt and black pepper: To taste Enhances all the flavors Fresh cracked pepper tastes best
- Yellow onion: One small diced Gives background sweetness Choose onions that feel heavy for their size
- Button mushrooms: One pound cleaned and dried Adds earthiness Small mushrooms have tender texture and mild flavor
- Garlic: Three to four cloves minced Brings a savory punch Use fresh not jarred for best aroma
- Fresh herbs: Two teaspoons chopped Try thyme or oregano for Mediterranean flair If using dried use only one teaspoon
- Vegetable broth: Quarter cup for moisture and gives a subtle boost of flavor Homemade or low sodium options are excellent
- Fresh parsley: Chopped for a burst of color and brightness Look for firm vibrant leaves
- Grated parmesan: To finish Lends a salty savoriness Freshly grated delivers the best taste and texture
Step-by-Step Instructions
- Heat the Pan:
- Add olive oil and half a tablespoon of butter to a large skillet Set the heat to medium high and wait until the butter is melted and the oil is shimmering
- Sauté the Zucchini:
- Scatter in the zucchini slices Season with salt and pepper Cook for three to four minutes turning occasionally until the slices are just fork tender Remove zucchini from the skillet and set aside Wipe out the skillet if there is any lingering liquid
- Build the Flavor Base:
- Return the skillet to the burner and add the remaining butter Let it melt over medium high heat Add the diced onion Cook for about two minutes until the onion has softened but not browned This step brings out the onion’s sweetness
- Cook the Mushrooms:
- Add mushrooms to the skillet Stir and let them cook for five to seven minutes until they have browned and released their juices Stir every so often so they caramelize on all sides
- Add Garlic and Herbs:
- Stir in the minced garlic and chopped herbs Cook for about twenty seconds letting the garlic just turn fragrant Take care not to let it brown
- Combine and Finish Cooking:
- Return the cooked zucchini to the skillet with the mushrooms Stir gently to mix everything well Cook for one minute so the flavors mingle and the zucchini reheats
- Deglaze:
- Pour in the vegetable broth Cook for two more minutes scraping any browned bits from the pan This creates a light sauce and blends all the flavors
- Taste and Adjust:
- Sample the veggies Taste for salt and pepper and adjust the seasoning as you like
- Serve:
- Remove the skillet from the heat Sprinkle with chopped fresh parsley and lots of grated parmesan Serve warm

My favorite ingredient here is definitely the fresh zucchini especially when I get it from my garden The bright green rounds are so tender and soak up the garlicky buttery sauce My kids always ask for a little extra parmesan on top and I am happy to oblige
Storage Tips
Keep leftovers in an airtight container in the fridge for up to three days The flavors actually improve overnight Gently reheat in a skillet over low heat with a splash of broth if needed to revive the sauce
Ingredient Substitutions
No fresh herbs Use dried but halve the amount Swap button mushrooms for cremini or even portabella for a deeper flavor Dairy free butter works well if you want a vegan version and nutritional yeast can replace parmesan
Serving Suggestions
This side goes perfectly with grilled chicken roasted fish or even tossed with cooked pasta For a vegetarian main top with a fried egg and some crusty bread
