Step‑by‑Step Instructions for Garlic Thyme Roasted Mushrooms in Browned Butter Sauce
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This temperature ensures your mushrooms will roast to perfection, developing a delicious caramelization. While that heats up, grab your baking sheet and line it with parchment paper for easy cleanup after roasting.
Step 2: Prepare the Mushrooms
In a large bowl, toss the cleaned mushrooms with 1 tablespoon of oil, salt, and pepper until well coated. Make sure each mushroom is evenly coated to prevent sticking during roasting. Once coated, arrange the mushrooms in a single layer on the prepared baking sheet, ensuring they have space around them for airflow.
Step 3: Roast the Mushrooms
Place the baking sheet in the preheated oven and roast the mushrooms for approximately 20 minutes. After 10 minutes, give them a gentle stir to promote even browning. The mushrooms are ready when they turn golden brown and have released their juices, looking beautifully caramelized.
Step 4: Brown the Butter
While the mushrooms roast, take a medium skillet and melt 1/4 cup of butter over medium heat. Keep a close eye on it, stirring occasionally. Once it turns a nutty golden brown and begins to foam, remove it from the heat to prevent burning, allowing those lovely flavors to develop.
Step 5: Add Garlic and Thyme
Immediately add the chopped garlic and thyme to the browned butter. The residual heat will release aromatic scents as you stir them together. Then, pour in 1 tablespoon of lemon juice, mixing everything smoothly. This vibrant addition balances the richness of the butter with a bright tang.
Step 6: Combine and Serve
Once the mushrooms are roasted to perfection, transfer them to the skillet and toss them in the decadent browned butter mixture. Adjust the seasoning with additional salt and pepper as needed. Serve your garlic thyme roasted mushrooms warm, and watch them elevate any meal!

Make Ahead Options
Preparing Garlic Thyme Roasted Mushrooms in Browned Butter Sauce is a breeze if you’re looking to save time during busy weeknights! You can clean and toss the mushrooms in oil, salt, and pepper up to 24 hours in advance and store them in an airtight container in the refrigerator. This allows the flavors to meld beautifully. Additionally, you can brown the butter and mix it with garlic, thyme, and lemon juice up to 3 days ahead; just refrigerate the mixture and reheat gently before tossing with the roasted mushrooms. When you’re ready to serve, simply roast the marinated mushrooms, combine them with the sauce, and enjoy delicious, gourmet results with minimal effort!
How to Store and Freeze Roasted Mushrooms
Fridge: Store your roasted mushrooms in an airtight container in the refrigerator for up to 2 days. This ensures they stay fresh and flavorful, ready for your next meal.

Garlic Thyme Roasted Mushrooms in Browned Butter Sauce Recipe FAQs
How do I select the best mushrooms for roasting?
Absolutely! When choosing mushrooms, look for ones that are firm and plump, avoiding any that have dark spots or are slimy. The ideal mushrooms should be free from blemishes and have a fresh, earthy scent. Button or cremini mushrooms work wonderfully, but you can also explore shiitake for a richer flavor.
How should I store leftover roasted mushrooms?
Stored correctly, your roasted mushrooms can stay fresh in an airtight container in the refrigerator for up to 2 days. Just make sure to let them cool to room temperature before sealing, as excess moisture can make them soggy.
Can I freeze roasted mushrooms?
Yes, you can! To freeze roasted mushrooms, lay them out in a single layer on a baking sheet and freeze until solid—this usually takes a few hours. Once frozen, transfer them to a freezer-safe bag, and they can stay in the freezer for up to 3 months. When you’re ready to use them, simply reheat in a pan or microwave, and consider adding a spritz of fresh lemon juice to revive their flavor.
What should I do if my mushrooms are soggy after roasting?
Oh no! Soggy mushrooms can happen if they were overcrowded on the baking sheet or if they weren’t dried thoroughly before roasting. To prevent this, always ensure that the mushrooms are in a single layer to allow steam to escape. If you do end up with soggy mushrooms, try reheating them in a skillet over medium heat with a little olive oil to help crisp them up again.
Are roasted mushrooms safe for pets?
Mushrooms can be safe for pets in moderation, but it’s essential to avoid wild mushrooms as they can be toxic. Domestic varieties like button or cremini are typically safe for dogs and cats, but always consult your veterinarian regarding your pet’s diet and any potential allergies.
Can I make this recipe dairy-free?
Absolutely! To make this dish dairy-free, simply substitute the butter with ghee or use a plant-based butter alternative. This way, you can still enjoy that rich, nutty flavor without any dairy ingredients, making it suitable for anyone following a dairy-free diet.
