Easy Marinated Mushrooms

These easy marinated mushrooms are some of the most addicting little bites I’ve ever made. Easy is right, too. They take no time at all to make. They are packed with flavor, a little sweet, a little heat and a bit of vinegar kick. I can guarantee that you will want to at least double the recipe because you won’t be able to stop eating them.
Easy Marinated MushroomsI used a mix of white button and cremini mushrooms, but you can use any mix of mushrooms you like. You do want to make sure you use mushrooms that are all about the same size or some will cook faster than others. You want them to all be cooked the same, not some soft and some not.

The marinade for these easy mushrooms is very good. I plan on using it for other dishes, including as a marinade for chicken.

Also try my garlic ricotta stuffed mushrooms and my easy marinated cheeses (delicious!).
