Garlic Butter Roasted Mushrooms

Are you searching for a simple, tasty mushroom side? These garlic butter roasted mushrooms fit the bill! They offer a rich, umami flavor. Plus, they’re easy to make and go well with any meal.

If you love savory veggies, like garlic butter mushrooms. They’re great alone or with polenta. Or as a side to mashed potatoes and more. Roast them at 450°F for a perfect color and juiciness. Adding lemon juice and thyme makes them even tastier.

Exact Ingredients (+ Possible Substitutes)

To make this tasty dish, you’ll need these roasted mushroom ingredients:

  • 500g/1lb of mushrooms (white button, Swiss brown/cremini, or large varieties like portabello)
  • 50g/3 tbsp of unsalted melted butter
  • 1 tbsp of olive oil
  • 2 finely minced garlic cloves
  • 1/2 tsp of salt
  • 1/2 tsp of pepper
  • Optional: 1 1/2 tbsp of lemon juice, 1 tsp of fresh thyme leaves or parsley

Mixing butter and oil for roasting makes the mushrooms tasty and even. If you can’t use garlic mushroom substitutes, you might like ghee or vegan butter. For something different, roast veggies like eggplant or zucchini. Just change the time they cook to be right.


The first step is to preheat your oven. Set it to a high 220°C/450°F. If you have a fan-assisted oven, use 200°C/400°F. This makes sure your mushrooms turn out perfectly golden.

Then, grab your fresh mushrooms. Mix them well with melted butter, oil, garlic, salt, and pepper. This step ensures every mushroom is packed with flavor. Place them on a baking tray in a single layer. Don’t let them overlap. This way, they’ll roast evenly and won’t get mushy.

Now, it’s time to roast the mushrooms. Put the tray in the oven and let them cook for about 25 minutes. Don’t turn or toss them. This lets them get that nice golden color and the right texture. If you’re roasting big mushrooms, put them cap side down. You may also add more butter mix for extra juiciness.

After roasting, add lemon and thyme if you wish. This adds a fresh lemon taste and nice aroma from thyme. It makes your mushrooms taste even better. Serve the hot dish right away. And enjoy your tasty garlic butter mushrooms.
