Ingredients

500g / 1lb mushrooms (button, Swiss brown/cremini, or 8 large mushrooms like portabello)
50g / 3 tbsp unsalted butter, melted

1 tbsp olive oil
2 garlic cloves, finely minced

1/2 tsp salt
1/2 tsp black pepper

1 1/2 tbsp lemon juice
1 tsp fresh thyme leaves (parsley can be used for color)

Instructions

Step 1: Preheat your oven to 220°C/450°F (200°F fan).

Step 2: In a large bowl, toss the mushrooms with melted butter, olive oil, minced garlic, salt, and pepper using a rubber spatula to coat evenly.
Step 3: Spread the coated mushrooms on a baking tray in a single layer and roast for 25 minutes without tossing or turning them.
Step 4: Remove the tray from the oven. If using lemon juice and thyme, push the mushrooms together on one side of the tray, drizzle with lemon juice, sprinkle thyme over, and toss to combine. Serve immediately.

Step 5 (for large mushrooms like portabello): Place mushrooms cap side down (stems facing up) in a snug medium baking dish, as they will shrink when cooked.
Step 6: Spoon 1 teaspoon of melted butter over each large mushroom and brush or drizzle the remaining butter around the edges. Drizzle with olive oil and sprinkle with salt and pepper.
Step 7: Roast for 20 minutes for tender mushrooms with slight firmness, or 25 minutes for fully tender mushrooms. Do not turn during roasting.

Step 8: After roasting, squeeze lemon juice over the mushrooms, sprinkle with thyme, and serve with the pan juices drizzled on top.

Tips & Variations

For extra flavor, add a sprinkle of grated Parmesan cheese after roasting.
Try using fresh parsley instead of thyme for a brighter, herbaceous note.

If you prefer a garlicky punch, increase the garlic to 3 cloves or add garlic powder before roasting.
Use cremini mushrooms for a deeper, earthier taste compared to button mushrooms.

Storage

Store leftover roasted mushrooms in an airtight container in the refrigerator for up to 3 days. To reheat, warm gently in a skillet over low heat or in the oven until heated through to preserve their texture and flavor.

FAQs

Can I use frozen mushrooms for this recipe?

Fresh mushrooms are recommended for the best texture and flavor, but if using frozen mushrooms, thaw and drain them well before roasting to avoid excess moisture.
