Simple perfection: Roasted Mushrooms with garlic butter, finished with a fresh squeeze of lemon and thyme leaves. Make this with button mushrooms or large mushrooms!
Juicy, buttery, garlic Roasted Mushrooms
Mushrooms are one of my all time favourite vegetables. I love the savoury flavour, and how versatile they are. From Mushroom Rice to Mushrooms on Toast, in pies, pasta, and an amazing creamy Mushroom Sauce you’ll want to put on everything, mushrooms are terrific as the hero in a dish or to add extra flavour.
In fact, if I had to choose one vegetable to live on forever, I’m pretty sure it would be mushrooms.
That’s how much I love them. And this is one of my favourite quick and easy ways to cook mushrooms – roasting them in garlic butter.
Roasted Mushrooms = juices for drizzling!
Both sautéed and roasted mushrooms are equally delicious but there’s one big difference between roasting and pan frying – the pan juices. When you roast mushrooms, they essentially create their own buttery sauce that you use to drizzle over the mushrooms when serving.
These pan juices are a combination of both the butter and oil drizzled on the mushrooms plus the juices from the mushrooms. Mushrooms are actually packed with an astonishing amount of liquid!
On the other hand, if you pan fry the mushrooms on the stove, all the mushroom juices evaporate. They have to, in order to get good colour on the mushrooms.
Plus, roasting mushrooms has one other big upside – it’s hands off effortless. No standing over a stove, stirring and turning. Just stick the pan in the oven and walk away!
How to roast mushrooms in the oven
It’s as easy as 1-2-3: Drizzle mushrooms with melted butter mixed with minced garlic, drizzle with oil then roast for 20 to 25 minutes at 200C/400F.
If I had my way, I would roast mushrooms in just butter for flavour. But if we used only butter, it would smoke out the oven because the smoke point of butter is too low.
So I solve this problem by using a combination of both butter and olive oil.
I like to finish with a fresh squeeze of lemon juice to cut through all the buttery goodness, as well as a sprinkle of a fresh herb. Thyme is my favourite – I think it complements mushrooms so well, but parsley and chives are also terrific.
This recipe works just as well with large and small mushrooms. For a meatless meal option, I like to use large mushrooms because it just feels more “meaty”!
What to serve these with Roasted Mushrooms
These mushrooms are ideal to serve as a side OR as a main. As a main, I love to place them on creamy mashed potatoes, mashed cauliflower (for a low carb, low cal option), with a side of Curried Rice or on polenta (pictured). It’s pictured in this post with a side of Garlic Sautéed Spinach.
When the mushrooms come out of the oven, you’ll see that there’s juices both in the caps of the mushrooms as well as in the pan. The pan juices are liquid gold! It’s garlicky and butter and mushroomy.
So transfer the mushrooms to the serving plates carefully to avoid spilling the juices in the mushroom caps, then drizzle with extra juices from the pan.
These babies are juicy, buttery, garlicky and you are going to love them. ??? – Nagi xx

Life of Dozer
I take back all that half-joking whining about how Dozer doesn’t give a toss when I’m away because he’s having a blast with his friends at the Golden Retriever Boarder’s place. She told me that every time he saw a short dark haired person, he would dash over to check if it was me! ?
