Recipe Science

  • Choose Cremini or Baby Bella mushrooms for roasting; their longer aging process enhances flavor and helps them maintain structure.
  • Olive oil coats the mushrooms’ surface, forming a protective layer that browns well and prevents drying during roasting.
  • Boost umami notes by glazing mushrooms with a soy butter sauce. As the butter’s milk solids brown, they add a butterscotch taste.

Why It Works

Mushrooms can be pretty bland on their own. But all you need is the proper cooking method and complementary ingredients to make them shine at the dinner table. Roasting in a high-temperature oven kicks off the browning process on the caps while concentrating the juices. To make a big batch for the family or a holiday, I use a baking sheet to do the work.

After about 30 minutes, the fungi will develop a caramel hue. To add a more robust umami taste, I toss them in a buttery soy sauce glaze. After a few minutes in the oven, the savory pieces of oven-roasted mushrooms are ready to serve! They pair well alongside a hearty protein like roasted chicken, flaky salmon, or a big juicy steak.

Ingredients You’ll Need

Ingredients to make a roasted mushroom side dish.
  • Mushrooms: I recommend using a brown mushroom type like Cremini mushrooms or Baby Bella as they are ideal choices for roasting. They also have a more robust, mature flavor compared to white Button mushrooms because they have aged longer. Their structure holds up well and doesn’t shrink down too much when cooking.
  • Oil: Fruity extra-virgin olive oil flavors the vegetables while providing a protective fat layer to prevent them from getting dried out.
  • Seasoning: Salt enhances the mushrooms’ natural umami flavor. A little bit of black pepper adds mild heat.
  • Sauce: The roasted mushrooms are tossed with a savory mixture of soy sauce sauce, balsamic vinegar, minced garlic, thyme, and melted butter.
  • Herbs: Fresh thyme is added to the sauce for an herbaceous note. Freshly chopped parsley is mild in taste and adds a bright green color to the brown mushrooms.

How to Roast Mushrooms

Step 1: Heat the Oven

Place the oven rack in the lowest position and preheat to 450ºF (232ºC).

Step 2: Prepare the Mushrooms 

In a pack of mushrooms, you’ll typically find a variety of sizes from small to large unless you handpick them at the market. Keep the smaller pieces that are no bigger than 1 ½ inches whole. Halve the medium-sized about 2-inches, and quarter the larger pieces. 

Wash the surface to remove any visible dirt or debris, and pat dry well. As long as you briefly rinse them, their spongy fungus won’t absorb too much water. Not to worry, though; the high heat from the oven will help drive off any residual moisture. Alternatively, wipe them with a damp paper towel.

Step 3: Season the Mushrooms 

I keep the seasoning simple- a high-quality olive oil, salt, and pepper. The fat coats the surface, creating a protective layer that browns nicely but doesn’t completely dry out while roasting. As the moisture releases, the salt works its way to the interior to season the inside of the mushroom.

Step 4: Roast

Roasting the mushrooms in the oven provides several advantages. First, you can cook a large batch compared to sauteed mushrooms, which is best for smaller portions. I prepared 2-pounds on a large rimmed baking sheet, but you could easily double the recipe. 

Cranking up the oven to 450ºF (232ºC) and roasting in the lower section quickly heats the baking sheet. In under 30 minutes, the vegetables develop a deep golden color and caramelized taste due to the Maillard reaction.

Tips for Perfect Execution: Spread the mushrooms in a single layer to ensure maximum contact with the hot pan. After about 15 minutes of cooking time, the mushrooms start to release their moisture in the dry heat. Letting pieces sit unmoved for at least 10 more minutes concentrates the savory flavor and evaporates most juices. Stir it, and you’ll see the caps and cut sides turn golden brown.

Step 5: Add the Sauce 

In a small bowl, add melted butter, soy sauce, balsamic vinegar, minced garlic, and chopped thyme. The milk solids in the butter browns, adding a nutty, butterscotch flavor.

Cook the mushrooms for about 5 more minutes to concentrate the flavors of the sauce.

Step 6: Ready to Serve

Sprinkle the roasted mushrooms with fresh herbs like parsley or basil for a pop of color right before serving. I like to serve it with creamy mashed potatoes and a slice of meatloaf or sauteed chicken.

Frequently Asked Questions

What is the difference between white and brown mushrooms?

White button mushrooms are light in color and have a mild savory flavor. Brown mushrooms like cremini and baby Bella are from the same variety as the white; however, they are harvested later, maturing and developing a richer taste and darker hue.

How do you bake mushrooms without getting soggy?

Fresh mushrooms contain about 85 to 95% water. Therefore it’s inevitable for the moisture to release when cooking. Roasting at a high of 450 degrees drives out the juices and evaporates them, so they brown quicker and don’t get soggy.

How long should mushrooms be cooked in the oven?

Roasted mushrooms need to cook until most of the moisture releases and the areas in contact with the pan turn golden brown. This process takes about 25 to 30 minutes in a 450-degree oven.

How do I make roasted mushrooms more flavorful?

Fresh mushrooms have a mild savory taste when cooked because they naturally contain flavor compounds called nucleotides. This gives a meaty flavor but isn’t very strong unless the fungi have been dried out. Adding some soy sauce rich in glutamates enhances the taste of nucleotides, making a more pungent umami taste. A splash of balsamic vinegar provides some acetic acid, adding a layer of zest and brightness to the dish.

  3. Cynthia says

    Ok, I guess I live a very sheltered life because I have never, ever heard of roasted mushrooms. So making this. I have a question when you are talking about the size of the mushrooms are you measuring east to west or north to south? I need to get this recipe right the 1st time I make it because someone in my household thinks this will not taste good.

  4. Josh says

    These mushrooms are amazingly good. Like 10x better than anything at a restaurant. No adjustments to the recipe, just a “little how-I-did-it”. At the beginning, I sprayed pam on the mushrooms, then salt & peppered. Got to try more of Jessica’s recipes.
