What You Need to Know Before You Start

Prep Time: About 10 minutes. This is mostly spent cleaning and cutting the mushrooms and gathering the other ingredients.

Cook Time: About 25 minutes in the oven, plus a few minutes to brown the butter.

Total Time: 35 minutes from start to finish.

Servings: Makes enough for 4 people as a side. For a larger crowd, the recipe can easily be doubled—just use two baking sheets so the mushrooms roast, not steam.

Difficulty: Beginner-friendly. If you can melt butter and use an oven, you can make this dish.

Best Mushrooms to Use:
You can use almost any type of common mushroom. White button and cremini are easiest to find and roast well, but baby bella and even portobello caps (cut in chunks) work too. Avoid using wet or very dirty mushrooms; wipe them clean with a damp paper towel to avoid sogginess.

Required Kitchen Tools

• Baking Sheet or Pan: A rimmed sheet helps catch any juices and lets mushrooms brown evenly.
• Mixing Bowl: For tossing mushrooms with oil and seasoning.
• Small Saucepan or Skillet: For melting and browning the butter.
• Spatula or Wooden Spoon: For stirring the butter as it browns and tossing the mushrooms.
• Measuring Spoons: For accurate seasoning.
• Oven Mitts: Always use oven mitts to protect your hands.

Ingredients (with Tips)

• Mushrooms (1 pound): Rinse lightly or wipe clean. Cut larger mushrooms in half or quarters so all pieces are roughly the same size.
• Butter (4 tablespoons): Unsalted gives you more control over the final saltiness.
• Garlic (2 cloves): Mince or finely grate for the best flavor. If you prefer a milder garlic taste, sauté briefly in the browned butter before adding.
• Fresh Thyme (1 teaspoon, or more to taste): Strip the tiny leaves from the woody stems. Dried thyme can be used, but fresh is best for aroma.
• Salt (about 1/2 teaspoon): Start with less; you can always add more at the end.
• Black Pepper (1/4 teaspoon): Freshly ground pepper has the most flavor.

Variations for Roasted Mushrooms

• With Cheese: A tablespoon of grated Parmesan or Pecorino Romano adds a salty, savory finish.
• With Herbs: Substitute or add parsley, rosemary, or chives for a different herbal note.
• Add Lemon: Squeeze a bit of lemon juice or add lemon zest for brightness before serving.
• Make it Spicy: Sprinkle in a pinch of chili flakes or smoked paprika for gentle heat.
• Umami Boost: A dash of soy sauce or Worcestershire sauce before roasting deepens the flavor.

How to Make Roasted Mushrooms with Browned Butter (Step-by-Step)

1. Prepare the Mushrooms

Start by cleaning your mushrooms. If there’s visible dirt, use a damp paper towel to gently wipe them clean. Avoid soaking mushrooms in water, as they absorb moisture and may not roast properly. Trim off any tough stem ends. If some mushrooms are much larger than others, cut them into halves or quarters to help all the pieces cook evenly.

2. Season and Arrange

Place the cleaned mushrooms in a mixing bowl. Drizzle with a little olive oil (about 1-2 teaspoons is enough). Sprinkle with salt and pepper. Toss well so every piece is lightly coated. Spread the mushrooms in a single layer on a rimmed baking sheet. Don’t crowd the pan—if the mushrooms are too close together, they’ll steam instead of roast.

3. Roast the Mushrooms

Put the baking sheet in a preheated 425°F (220°C) oven. Roast for about 20–25 minutes, stirring halfway through. The mushrooms should shrink, turn golden, and release some juices. When finished, they’ll look brown at the edges and feel tender.

4. Brown the Butter

While the mushrooms roast, place the butter in a small saucepan over medium heat. Let it melt, then swirl the pan or stir gently. The butter will foam and sizzle, then start to turn a deeper yellow and release a toasty smell. Watch closely, as browned butter can go from perfect to burned quickly. As soon as you see brown flecks at the bottom and the butter smells nutty, remove it from the heat. Stir in the minced garlic and fresh thyme. The hot butter will gently cook the garlic, releasing even more flavor.

5. Toss and Finish

When the mushrooms are done, move them to a serving bowl or back into your mixing bowl. Pour the warm browned butter mixture over the mushrooms and toss to coat. Taste, and add more salt or pepper if needed.

Serving and Presentation Ideas

• Side Dish: Serve warm as a side with roast chicken, steak, or pasta.
• Topping: Spoon over toasted bread for a rustic appetizer.
• Mix-In: Add to omelets, pasta, or risotto.
• Garnish: A little extra fresh thyme or a sprinkle of cheese on top makes a nice finishing touch.

Storing Roasted Mushrooms

• Fridge: Keep leftovers in an airtight container in the refrigerator for up to 3 days.
• Reheat: Warm gently in a skillet over low heat, or in the microwave in short bursts.
• Freezer: It’s best not to freeze, as the mushrooms will change texture.

Tips and Tricks for Success

• Don’t Crowd the Pan: Mushrooms roast best when spread in a single layer with space between pieces.
• Use High Heat: Roasting at 425°F (220°C) helps the mushrooms caramelize and get golden brown.
• Brown Butter Carefully: Watch the butter as it browns—remove from heat as soon as it smells nutty and you see brown bits.
• Adjust Seasonings: Taste at the end and add more salt, pepper, or fresh herbs to suit your liking.
• Experiment with Flavors: Try a squeeze of lemon, sprinkle of cheese, or different fresh herbs to keep things interesting.

Roasted Mushroom FAQs

Can I use different types of mushrooms?
Yes. A mix of mushrooms adds texture and flavor. Try shiitake, oyster, or portobello, but adjust roasting time based on size.

What is browned butter?
Browned butter is regular butter that’s been cooked until the milk solids toast. It has a warm, nutty aroma and deep flavor that enhances both savory and sweet dishes.

Do I have to use fresh thyme?
Fresh thyme has better flavor, but dried works if that’s what you have. Use half as much dried, since it’s more concentrated.

Can I make this ahead of time?
Roasted mushrooms are best served fresh, but you can prep everything ahead and reheat gently before serving.

Can I make it vegan?
Yes. Use a vegan butter substitute and ensure your other ingredients are plant-based.
