Ingredients:
- 500g / 1lb mushrooms (button, Swiss brown, or cremini)

Instructions:
- Preheat your oven to 220°C/450°F (200°F fan).
- In a large bowl, toss the mushrooms with melted butter, olive oil, minced garlic, salt, and pepper, using a rubber spatula to ensure even coating.
- Spread the seasoned mushrooms on a baking tray in a single layer and roast in the preheated oven for 25 minutes without tossing or turning.

- Serve the Roasted Garlic Butter Mushrooms immediately, allowing their irresistible aroma to entice your senses.
How to Roast Large Mushrooms (e.g., Portabello):
- Place the mushrooms cap side down (stems facing up) in a medium baking dish, ensuring they fit snugly to prevent excessive shrinking.
- Spoon 1 teaspoon of butter over each mushroom, then use the remaining butter to brush the edges or drizzle carefully over them.
- Drizzle olive oil over the mushrooms and sprinkle with salt and pepper.
- Roast in the preheated oven for 20-25 minutes until tender, without turning. The mushrooms will release juices, creating a flavorful sauce.
- Finish by squeezing a bit of lemon juice over the mushrooms and sprinkling with fresh thyme leaves before serving.
Recipe Notes:
- Serving Suggestions: Our Roasted Garlic Butter Mushrooms are versatile and can be paired with a variety of dishes. Enjoy them alongside creamy mashed potatoes, on toast spread with ricotta cheese, or served over polenta with garlic sautéed spinach. They also complement pasta dishes, though the sauce quantity may be insufficient to coat pasta entirely.

HOW TO ROAST LARGE MUSHROOMS (EG PORTABELLO)
- (vedio here for large mushrooms) Place mushrooms cap side down (ie stems facing up) in a medium baking dish (so they are kind of snug – they shrink).
- Spoon 1 tsp of butter over each mushroom, then use the rest to brush the edges (or carefully drizzle over edges).
- Drizzle over olive oil, sprinkle with salt and pepper.
- Roast for 20 minutes (tender but still a slight firmness) or 25 minutes (tender) – no turning. There will be juices in the pan and plenty pooled in the mushrooms caps.
- Squeeze over a bit of lemon juice, sprinkle with thyme. Serve mushrooms, drizzled with pan juices (see notes for serving suggestions).
Recipe Notes:
1. Serving suggestions: Pictured in post with polenta (I use quick cook) and Garlic Sautéed Spinach, and on toast spread with ricotta. It’s also lovely with mashed potato or anything else to soak up all those juices (even low carb Creamy Mashed Cauliflower!).
It doesn’t make enough sauce to coat pasta, though you could use a small serving of pasta.
