Preheat your oven to 400°F (200°C).

In a medium mixing bowl, combine soy sauce, honey, olive oil, minced garlic, thyme, and black pepper. Stir until honey dissolves.

Slice the mushrooms into even pieces and toss in the marinade until coated.

Line a baking sheet with parchment paper or grease it lightly with oil.

Spread the marinated mushrooms in a single layer on the prepared baking sheet.

Roast the mushrooms for 20–25 minutes, stirring halfway through.

Let the mushrooms rest for 5 minutes after removing from the oven.

Sprinkle with sesame seeds and parsley before serving.
