Roasted Mushrooms in a Browned Butter Ingredients
Here’s what you need to create savory Roasted Mushrooms in a Browned Butter, Garlic, and Thyme Sauce.
For the Mushrooms

- Oil – 1 tablespoon oil; helps in roasting and enhances flavor—olive oil works wonderfully as a substitute.
- Salt and Pepper – To taste; essential seasoning that amplifies the overall dish’s taste.
For the Sauce
- Butter – 1/4 cup butter; the base of your sauce, adding richness and depth.
- Garlic – 2 cloves garlic, chopped; this provides savoriness, offering a delightful fragrance when browned.
- Thyme – 1 teaspoon thyme, chopped; imparts a lovely herbal note, with dill as a great alternative if needed.

Step‑by‑Step Instructions for Roasted Mushrooms in a Browned Butter, Garlic, and Thyme Sauce
Step 1: Preheat the Oven
Start by preheating your oven to 400°F (200°C). This temperature is crucial for achieving perfectly roasted mushrooms that are tender on the inside and slightly crispy on the outside. While the oven heats up, you can prepare the mushrooms for roasting, ensuring they soak up all that delicious flavor.
Step 2: Prepare the Mushrooms
Clean 1 pound of mushrooms (button or cremini) by wiping them with a damp cloth. Once dry, place them in a large mixing bowl and drizzle 1 tablespoon of oil over them. Season with salt and pepper to taste, then toss gently until the mushrooms are well-coated. Spread them out in a single layer on a baking sheet for even roasting.
Step 3: Roast the Mushrooms
Place the baking sheet in your preheated oven and roast the mushrooms for approximately 20 minutes. Halfway through, give them a gentle stir to ensure even cooking. You’ll know they’re ready when they turn a lovely golden brown and caramelize slightly, releasing a rich earthy aroma that fills your kitchen.
Step 4: Make the Browned Butter
While the mushrooms are roasting, melt 1/4 cup of butter in a saucepan over medium heat. Continuously stir the butter as it melts to prevent burning. Watch closely as it transforms; it should turn a beautiful hazelnut brown and emit a nutty fragrance, which usually takes around 5-7 minutes. This deepened flavor will be the highlight of your roasted mushrooms.
Step 5: Add Aromatics
Once the butter has browned, remove the saucepan from the heat. Stir in 2 chopped garlic cloves and 1 teaspoon of fresh thyme, along with 1 tablespoon of lemon juice. The heat will release the aromatic essence of the garlic and thyme, creating a luscious sauce that beautifully complements the roasted mushrooms.
Step 6: Combine and Serve
When the mushrooms are finished roasting, take them out of the oven and transfer them to a large serving bowl. Pour the browned butter mixture over the mushrooms, tossing gently to coat them thoroughly. Adjust seasoning with additional salt and pepper as necessary. Serve warm as a vibrant side dish that enhances any meal with its delightful flavors.

How to Store and Freeze Roasted Mushrooms
Fridge: Store leftover roasted mushrooms in an airtight container in the refrigerator for up to 3 days. This helps maintain their flavor and texture.
Freezer: If you want to keep them longer, freeze the roasted mushrooms in a single layer on a baking sheet for about 1 hour, then transfer to a freezer bag for up to 2 months.
Reheating: To reheat, place the mushrooms on a baking sheet and warm them in a preheated oven at 350°F (175°C) for about 10-15 minutes. This will help revive their crispness while keeping the delicious browned butter flavor intact.
Note: The texture may be slightly softer after freezing, but they will still complement many dishes beautifully!
Make Ahead Options

When you’re ready to serve, simply roast the mushrooms and reheat the sauce gently to finish. This way, you’ll retain all the fresh flavors while saving precious time on busy weeknights!
