If you’ve ever popped a juicy marinated mushroom into your mouth and thought, “Whoa, where have these been all my life?” — you’re not alone. These little flavor bombs are earthy, tangy, a touch spicy, and absolutely addictive. Perfect as an appetizer, salad topper, or even as a fancy addition to your next charcuterie board — these marinated mushrooms are the real MVP of any spread!
Why This Recipe Works
We’re taking mushrooms — already delicious in their umami-packed glory — and turning them into something next-level. The combo of Shiitake Mushroom Oil, rice wine vinegar, and a hint of red pepper flakes makes every bite sing. The acidity from the lemon juice and vinegar cuts through the richness of the oils, giving you that perfect balance of zippy and savory. Plus, letting them marinate overnight means the flavors soak in deep, giving you mushrooms so flavorful you’ll want to put them on everything.

What is My Take on Marinated Mushrooms?
This recipe is all about bold flavor with minimal effort. I love that you can use a mix of portabella and shiitake mushrooms for depth (though regular olive oil totally works too!). It’s the kind of dish that feels fancy but requires almost no hands-on time. Just simmer, mix, and chill — literally.
They’re perfect for those “I need something impressive but easy” moments — like when guests show up last-minute or you want to elevate a weeknight dinner without even turning on the oven.
Make it a Meal
These marinated mushrooms are incredible spooned over a grilled steak, mixed into Summer Okra Pasta Salad, or layered onto a Healthy Air Fryer Eggplant Parmesan. They also make an amazing topping for bruschetta or flatbreads.
