These Roasted Mushrooms are such a deliciously easy side dish, perfect for serving for dinner with a steak or roast chicken. Or use them to make a delicious mushroom sauce for stirring through pasta.
The mushrooms are dotted with butter and then baked in the oven with garlic and thyme. This creates a wonderful garlic butter that slowly soaks into the mushrooms, giving them so my flavor and keeping them tender and juicy.
This simple side is naturally gluten-free, low carb and so easy that you'll wonder why you haven't cooked mushrooms in the oven before!

How to Roast Mushrooms in the Oven
Roasted or Baked Mushrooms benefit from some form of fat, this stops them drying out in the oven.
Here we are using butter. Once the mushrooms are in a baking dish the butter is dotted over the top ready to melt over the mushrooms.
In addition to the butter, we are going to add two of mushrooms best friends! Garlic and Thyme.
Mushrooms and Garlic is a match made in heaven, especially when paired with butter and some floral herby thyme.
When the mushrooms are placed in the oven, the butter melts and slowly as the mushrooms release some of their wonderful juice, you get a rich garlic butter at the bottom of your roasting dish.
How long to roast mushrooms for?
Mushrooms need to be baked at 400ºF/200ºC for 30 minutes.
You can also increase the temperature to 450ºF/230ºC and roast for 20 minutes.
I prefer the longer cook at a lower temperature as this gives the mushrooms time to fully soften and release some wonderful mushroomy juices into the melted butter. And it is that mushroom infused butter that makes this side so delicious and packed with flavor! Perfect for spooning over a chicken breast - which can be roasted at the same temperature for 20 minutes!!!

This dish is beautiful before it is cooked. Just look at the roasting dish of mushrooms. It is so pretty. But the finished product is all about the taste. And let me tell you that taste is AMAZING! These roasted mushrooms aren't the prettiest, but I don't care because prettiness fades. What matters is what is inside. And when it comes to food that means how it tastes. And these taste good!!!!!

These smell AMAZING when they are roasting!!!! Seriously, the day they invent a way for me to send food aromas through my blog, well that is the day you all need to buy bigger pants! #notevensorry
There are very few things better in this world than the smell of garlic, thyme and butter. It is up there with my favourite smells ever.
Come on, tell me you have favourite smells too!!!!!
Yes? No? Come on share!!! I'll tell you mine. (in no particular order)
- Freshly washed babies (oh that just pulls on my heart strings)
- The smell of the garden after the rain. (Fresh, delicious and clean)
- L'Air du Temps perfume (Because it reminds me of my Mummy)
- The smell of fresh cut grass. (memories of being 10 and having the whole summer holidays ahead of you)
- The smell of the ocean on a winters day. (The most perfect place to be. Wrapped in a scarf and warm socks)
- Old Spice after shave (It smells like Stew and always makes me happy)
- Fried onions. (They just make you hungry!!!)

Can I make these ahead of time to take to a "bare bones" cabin for dinner - would like to make at home and take for dinner there. They look wonderful
Claire McEwen says
Hi Elaine,
I often make this in advance and then store in containers, you find the mushrooms all stick together where the butter solidifies, but the flavor is still great for 2-3 days.
I have had some luck microwaving it, but you do have to heat it on low and watch it closely so the butter doesn't start to taste gross.
For me the easiest and tastiest way to reheat in is a skillet or saucepan, just stirring over a medium heat until warmed through.
Hope that helps 😀
Enjoy your time in the cabin Cx
