Instructions
Step 1: Roast the Mushrooms
Preheat oven to 425°F (220°C).
In a large mixing bowl, combine mushrooms, sliced onion, olive oil, sea salt, black pepper, granulated garlic, and ground thyme. Toss until evenly coated.
Spread the mixture evenly on a baking sheet and roast for 20-30 minutes, stirring halfway through, until the mushrooms are deeply caramelized.
Step 2: Brown the Butter
In a small saucepan over medium heat, melt the butter. Cook for 5-7 minutes, stirring frequently, until the butter turns golden brown and releases a nutty aroma.
Remove from heat and immediately stir in the minced garlic and fresh thyme.
Step 3: Finish & Serve
Drizzle the brown butter mixture over the roasted mushrooms and gently toss to coat.
Adjust seasoning if needed, serve warm, and enjoy!
