Roasted Mushrooms with garlic and Parmesan cheese make the perfect side dish recipe. I love these over a grilled steak or chicken. It is an easy vegetable idea for Thanksgiving or Christmas dinner that will make anyone a mushroom lover, even kids!
With six food loving kiddos, I’ve learned that there are certain holiday food traditions you just can’t mess with or you will “ruin Thanksgiving forever!” That was the reaction when I suggested adding a side dish of mushrooms to our traditional Thanksgiving feast.

To combat the six kill-joys I have been blessed with, I made a batch of these roasted mushrooms a few weeks ago along side some gorgeous grilled steaks and seasoned with Parmesan and garlic. It was my version of a “soft opening” for a new holiday side dish.
They went over beautifully, except with my 4 year old who has become obsessive about “things” touching her food. Suddenly, all food must to be served in it’s natural state with no visible seasoning or complimentary ingredient stuck to it. Yeah, right. “Eat it or don’t” is the rule in our house but remember, there is no more food until breakfast 🙂
I acquired some monster sized mushrooms from Sam’s Club so most of my mushrooms had to be cut down to a smaller size, but if your mushrooms are normal size, just roast them whole. Be prepared for these to shrink, a lot! I would say the volume of the mushrooms was easily reduced by half. Next time, I will definitely be making a double recipe because for our big family, one pound just didn’t go far enough. They were that scrumptious!

If you would rather grill your mushrooms, then go print out my killer recipe for Grilled Mushroom Skewers!

When I try to pin this recipe, the photo does not come up to be pinned with this recipe. Just fyi as the skewers aren’t my desired preparation method for this recipe.
Thanks Susie! I’ll look into it

I’m making this tomorrow for our Christmas…which is your preference…green or black olives? I am leaning towards the green because that is more unique…also, at that high temp I’m thinking the garlic and parsley should burn…NO?
Hi Lonnie! I prefer the black and no, the garlic and parsley don’t burn.

Can I replace Parmesan cheese with mozzarella?
I think you could, but you would end up with a very different type of dish. Parmesan is high in flavor and salt, while mozzarella have very little of both. Plus, your mozzarella will melt and parmesan stays dry in this dish.
