Roasted Mushrooms

Roasted mushrooms are so easy to make but boast a complex flavor, enhanced by tangy balsamic vinegar and fragrant thyme.

I’m on a roasted vegetable kick. Actually, that “kick” has been going on for quite awhile now. Maybe I’m just plain in love with roasted vegetables.

I also happen to love thyme. It’s one of the easiest herbs to grow — mine comes back year after year so I don’t even need to plant it anymore. I can’t say the same about my cilantro. I have the hardest time growing that.

And roasted mushrooms are my favorite of all roasted vegetables. I could eat an embarrassing amount of them, but I guess it is better than jelly beans, right? After you try this recipe, you’ll want to give these marsala roasted mushrooms a try. They are out of this world good! And don’t get me going on roasted mushroom risotto.

Once you master roasting mushrooms, sautéed mushrooms should be next on your list. I’ll teach you how to sauté mushrooms perfectly every single time – there’s a specific method! You can also air fry mushrooms.

About This Recipe

These roasted mushrooms are so flavorful, thanks to the thyme I already mentioned, but they get also a nice bit of tang from balsamic vinegar and Dijon mustard which complements the rich flavor of the roasted mushrooms. Lots of umami and good flavor!

They are easy to make. With only five ingredients, you can have them in the oven in ten minutes! Most of that time is spent cleaning the mushrooms.

As an aside, I just started using my air fryer for roasting vegetables. It’s pretty amazing. If you’d like to try roasting mushrooms in your air fryer, try these Air Fryer Mushrooms with Garlic and Shallots. They are so good! Air fryers do a good job making crispy zucchini chips and Brussels sprouts too.

Back to these mushrooms! I’ll run you through the recipe and get you started with lots of extra helpful tips.

What You’ll Need

• Mushrooms: Yup, you definitely need mushrooms to make roasted mushrooms. Any meaty variety will work. White button mushrooms are the most common type found in supermarkets. Baby bellas or cremini mushrooms are a good choice, too.
• Olive Oil: Olive oil adds great flavor and keeps the mushrooms from sticking to the pan. If you prefer grapeseed or avocado oil, that’s fine.
• Balsamic Vinegar: You’ll love the rich flavor and color that dark balsamic adds to this dish. White balsamic vinegar works well, too.
• Salt and Pepper, to taste
• Fresh Thyme: If you happen to be out of fresh thyme, use dried thyme but use less, about 1/4 teaspoon.

How To Make This Recipe

Begin by preheating your oven. Anytime you roast anything, the oven should be good and hot before you stick the pan in. Sometimes I even preheat the oven with the empty sheet pan so it’s sizzling hot when I add the mushrooms.

Next, blend together the olive oil, balsamic vinegar, and black pepper in a large bowl. Add the clean mushrooms, and toss until the mushrooms are well-coated.

Arrange the mushrooms in a single layer on a large rimmed baking sheet. Don’t overcrowd the mushrooms – they need air to roast properly and not steam.

Bake for fifteen to twenty minutes, stirring once. The mushrooms should be golden brown and tender. Sprinkle with the thyme and salt to taste. That’s all there is to it! 

Roasted mushrooms are good served hot out of the oven or at room temperature.

How To Serve Roasted Mushrooms

Roasted mushrooms are a perfect side dish to any great meal — pork, chicken, steak, tofu, you name it. Try mushrooms with roasted salmon. You can roast them both at the same time.

They are fantastic tossed on a green salad too. Double the amount of the oil/vinegar mixture that you use to roast the mushrooms and use half as a vinaigrette for your salad. Easy!

Roasted mushrooms add so much to bowls and grain salads, like this farro salad with butternut squash, bacon and cranberries. Add them to pizza, tacos or nachos. Make amazing appetizers like wild mushroom crostini with goat cheese.

Or just munch on these roasted gems like candy. It’s almost the same, right?

FAQs

Make It Your Own

• Substitute a different variety of mushroom. I’d love to try this recipe with morels if I can only get my hands on some!
• Tweak the seasoning. Add 1/4 teaspoon garlic powder (or more if you love garlic). Dried herbs such as Italian seasoning, rosemary, oregano, or basil are good. Really, the seasoning is totally up to you. Be creative!
• Don’t like mushrooms? Okay, this recipe may not be the one for you but guess what? You can substitute a different vegetable for the mushrooms. Try Brussels sprouts, broccoli, green beans, carrots, asparagus, parsnips, etc. The balsamic and thyme combo is good on everything! P.S. A mixture of vegetables is good, too, as long as you combine vegetables that cook in about the same amount of time.
• Don’t want to turn the oven on? This recipe can be made in a skillet or air fryer. Or try these sautéed mushrooms with wine and garlic or creamy Tuscan mushrooms.

Make-Ahead and Storage Tips

Roasted mushrooms can be made ahead. They’ll keep in the refrigerator in a tightly covered container for up to five days. While fresh mushrooms can’t be successfully frozen, roasted mushrooms can be frozen for up to three months.

Make a double or triple batch while you’ve got everything out and the oven is on, and store some for future use.

To reheat, thaw frozen mushrooms overnight in the fridge if you can. Gently reheat them in a skillet on the stove until heated through. If necessary, add a drop or two of water, broth, or balsamic vinegar to rehydrate.
