Savory Roasted King Trumpet Mushrooms
- 4 large King Trumpet Mushrooms
- 2 tablespoons olive oil
- 2 teaspoons fresh thyme leaves, finely chopped
- 2 teaspoons fresh rosemary, finely chopped
- 4 cloves garlic, minced
- Salt and black pepper to taste
- 1 tablespoon balsamic vinegar
- Optional: Microgreens for garnish


Step 1 - Clean and Slice Mushrooms

Start by cleaning the King Trumpet Mushrooms gently with a damp cloth to remove any dirt or debris. Trim the tough ends of the stems, and slice the mushrooms lengthwise into 1/2 inch thick slices.

Step 2 - Mix Ingredients

In a small bowl, mix together the olive oil, thyme, rosemary, and minced garlic.

Step 3 - Prepare Mushrooms

Lay out the sliced mushrooms on a baking sheet lined with parchment paper. Brush the olive oil and herb mixture evenly over the mushroom slices. Sprinkle a pinch of salt and black pepper over the mushrooms to taste.

Step 4 - Roast Mushrooms

Preheat your oven to 400°F (200°C). Once the oven reaches the desired temperature, place the baking sheet in the oven. Roast the mushrooms for about 15-20 minutes, until they’re golden brown and tender. Take the mushrooms out of the oven and drizzle with balsamic vinegar. Toss gently to coat, then transfer to a serving platter.

Step 5 - Garnish & Serve

If desired, garnish with a scattering of fresh microgreens before serving.
