Roasted Mushrooms are tender, golden, and tossed in a rich garlic butter sauce loaded with fresh herbs. Roasting at high heat concentrates their savory, earthy flavor and gives them beautifully browned edges. They come together in about 30 minutes and pair with almost any main, just like our roasted Brussels sprouts with bacon and green bean stir fry.

Roasted at high heat and finished in a fresh herb garlic butter, these roasted mushrooms are an easy, savory side dish that tastes like a restaurant made it, right up there with our savory mashed sweet potatoes.

Quick Answer
To roast mushrooms without making them soggy, toss them with a little oil and spread them in a single layer on a sheet tray, then roast at a high heat of 425 degrees F. The high temperature lets moisture evaporate, so they brown and concentrate in flavor instead of steaming, the same trick that crisps our air fryer baked potatoes.

How to Make Roasted Mushrooms

Recipe Tips & Tricks
- Do not wash, brush. Wipe the mushrooms clean instead of soaking them so they do not get waterlogged.
- Use a hot oven. 425 degrees F is key for browning instead of steaming.
- Single layer. Give the mushrooms room on the tray so they roast evenly.
- Do not brown the garlic. Cook it just until fragrant so it stays sweet, not bitter.
- Finish with fresh herbs. Adding parsley at the end keeps it bright, like our green bean stir fry.
Serving Ideas and Suggestions
These roasted mushrooms are a versatile side that works for everything from a weeknight dinner to a holiday spread.
Serve them hot, spooning the garlic butter over the top. They are perfect next to baked chicken thighs, Marry Me chicken, or braised short ribs, with mashed potatoes or crispy baked potatoes on the side.
Pair them with more easy sides like sauteed brussel sprouts, mashed sweet potatoes, or a bowl of butternut squash soup. You can also pile them on toast or fold them into aglio e olio.

Roasted Mushrooms FAQs
Baby bella (cremini) mushrooms are ideal because they are meaty and hold their shape, but button mushrooms or a mix of wild mushrooms also roast beautifully. Just keep the pieces a similar size so they cook evenly.
It is best to wipe mushrooms clean with a damp paper towel or a soft brush instead of soaking them. Mushrooms absorb water quickly, which can make them steam rather than roast and brown.
Yes. Roast and toss them in the garlic butter, then store in the fridge for up to 3 days. Reheat in a hot oven or skillet to bring back some browning, then serve with baked chicken tenders.
Store cooled mushrooms in an airtight container in the refrigerator for up to 3 days. Reheat in a skillet over medium heat or in a 400 degree F oven so they crisp back up instead of turning rubbery.
Absolutely. Swap the butter for a plant-based butter or use all olive oil for the sauce. You will still get plenty of garlicky, herby flavor.
They pair with almost anything, including steak, grilled chicken, pork, pasta, or a holiday roast like our moussaka. You can also stir them into rice and grain bowls.
Savory, buttery, and ready in half an hour, these roasted mushrooms are the kind of easy side dish you will come back to again, right alongside our loaded mashed potato cakes.

Notes
- Use a Hot Oven: Roasting the mushrooms at 425°F helps to draw out moisture and creates a beautiful golden brown crust. Make sure your oven is fully preheated for the best results.
- Don’t Crowd the Pan: Place the mushrooms in a single layer on the baking sheet. Overcrowding will cause them to steam instead of roast, resulting in soggy mushrooms.
- Fresh Herbs Make a Difference: Fresh rosemary, thyme, and parsley really elevate the flavor of the garlic butter sauce, so try to use fresh herbs if possible.
- Deglaze with Wine: If you want to add extra depth to the garlic butter sauce, try deglazing the pan with a splash of white wine before adding the mushrooms.
- Flip Halfway: Be sure to flip the mushrooms halfway through the roasting time to ensure they cook evenly on all sides.
- Add Extra Umami: For even more umami flavor, drizzle a little soy sauce over the mushrooms before serving.

It’s more of an aromatic than to eat 🙂
I am just wondering why you still have the skins on the garlic?? Does that like limit the garlic taste or something? Personally, I would roast the garlic and then use it in the finale stage of the recipe to bring in a mild taste of the garlic and not the sharp taste of the that fresh garlic has.
These mushrooms sound earthy, delicious, and OMG garlic & butter pairing for the win!
I just bought some mushrooms to go with my steak for dinner, this recipe is going to be the perfect side dish!
