Ingredients
Scale
For Small to Medium Mushrooms
- 500g (1lb) mushrooms (button or Swiss brown/cremini)
- 50g (3 tbsp) unsalted butter, melted
- 1 tbsp olive oil
- 2 garlic cloves, finely minced
- 1/2 tsp salt
- 1/2 tsp pepper
- 1 1/2 tbsp lemon juice
- 1 tsp fresh thyme leaves (or parsley for color)
For Large Mushrooms (e.g. Portabello)
- 8 large mushrooms (like portabello)
- Butter: about 1 tsp per mushroom plus extra for brushing edges (part of the 50g melted butter)
- Olive oil, to drizzle
- Salt and pepper, to taste
- Lemon juice, for squeezing over
- Fresh thyme leaves, for sprinkling
Instructions
- Preheat Oven: Preheat the oven to 220°C (450°F) or 200°C fan (about 400°F fan).
- Prepare Mushrooms (Small to Medium): In a large bowl, toss the mushrooms with melted butter, olive oil, finely minced garlic, salt, and pepper using a rubber spatula until evenly coated.
- Roast Mushrooms: Spread the coated mushrooms evenly on a baking tray. Roast in the oven for 25 minutes without tossing or turning to allow even caramelization.
- Add Lemon and Herbs: After roasting, push the mushrooms to one side of the tray, drizzle with lemon juice and sprinkle with fresh thyme leaves, then gently toss the mushrooms to combine flavors. Serve immediately.
- Prepare Large Mushrooms (Portabello): Place mushrooms cap side down (stems facing up) snugly in a medium baking dish to accommodate shrinking during roasting.
- Butter and Season Large Mushrooms: Spoon about 1 tsp melted butter over each mushroom and brush the edges with the remaining melted butter. Drizzle olive oil on top and sprinkle with salt and pepper.
- Roast Large Mushrooms: Roast for 20 minutes for tender but slightly firm texture, or for 25 minutes for fully tender mushrooms. Do not turn the mushrooms during roasting. The mushrooms will release juices into the pan and caps.
- Finish and Serve Large Mushrooms: Squeeze fresh lemon juice over the roasted mushrooms, sprinkle with thyme, and serve drizzled with pan juices.
Notes
- Use garlic finely minced to ensure even distribution and a strong garlic flavor.
- Do not toss mushrooms during roasting to allow a good caramelized crust to form.
- Adjust roasting time for large mushrooms depending on your texture preference (20 minutes for slight firmness, 25 minutes for tender).
- Fresh thyme or parsley adds brightness and color; fresh herbs are recommended for best flavor.
- This dish pairs well with grilled meats, roasted chicken, or as a side to pasta dishes.
