As a side dish, you can’t go wrong with these Roasted Mushrooms with Garlic Butter Sauce. An essential and a classic, for a holiday…or any day! Shown here with our Garlic Butter Steak Bites. Let me show you how I make them.

What types of mushrooms work best in this recipe?

I prefer to use brown button or baby bella mushrooms for this recipe, but any mushroom will work here including white button. Cremini or baby bella typically have more flavor. Simply trim the stem and wipe clean. I prefer using a damp paper towel.

In a large bowl, toss the mushrooms with a neutral flavored oil, salt and pepper.

How to roast mushrooms

Place the mushrooms cap side up on a baking sheet and in a preheated oven, bake until golden. This should take anywhere from 15-25 minutes depending on your oven.

I prefer roasting the mushrooms because not only do they get an amazing flavor from this process, but they also retain a bit of texture which I love.

In a non-stick skillet, melt the butter and add minced garlic. Add the mushrooms, tossing to coat. I like to give them a minute or two just so the flavors can really get into the mushrooms.

The only thing that is left to do in this super simple recipe is to garnish with freshly chopped Italian parsley and enjoy!
