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

Cook the Mushrooms:

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
