Here’s a quick and easy mushroom recipe – Roasted Mushrooms in Garlic Butter, finished with an optional squeeze of lemon and sprinkle of thyme leaves which goes beautifully with golden brown mushrooms baked in the oven.
Make this with button mushrooms or large mushrooms! A great quick side dish that pairs with everything from steaks to Roast Chicken, or make a meal out of it as I do!
How to Roast Mushrooms in the oven
And here’s how to roast mushrooms in the oven – simply toss in butter, oil, garlic, salt and pepper. Spread on baking tray and bake for 25 minutes at 220°C/450°F (hot oven = better colour!). No turning or tossing – you get better colour by leaving the oven closed the whole time!
Large Roasted Mushrooms = juices for drizzling!
This roasted mushroom recipe works equally well for large or small mushrooms, though the directions are slightly different so I’ve included both in the recipe card.
But with the large mushrooms, you will get far more mushroom juices that you can essentially use as a buttery mushroom sauce when serving. The juices pool in the cap of the mushrooms (small mushrooms don’t have the same shape so the juices don’t pool the same way) and in the pan as well.
Here’s a photo of roasted large mushrooms. I really like using large mushrooms to serve as a main dish, as pictured below served on polenta.
What to serve these with Roasted Mushrooms
These mushrooms are ideal to serve as a side OR as a main. As a main, I love to place them on creamy mashed potatoes, mashed cauliflower (for a low carb, low cal option), with a side of Curried Rice or on polenta (pictured). The large mushrooms are pictured above with a side of Garlic Sautéed Spinach.
As a side, they literally go with anything. From something as simple as Juicy Baked Chicken Breasts* to crispy pan seared fish fillets, a big juicy steak, garlic prawns or some pork chops. (* Bake these on the high shelf and these mushrooms on the low shelf).
Whatever you serve them with, they’re going to be a hit. These babies are juicy, buttery, garlicky and you are going to love them. 🍄🍄🍄 – Nagi xx
Ingredients
- 500g / 1lb mushrooms , button or Swiss brown / cremini OR 8 large (like portabello)
- 50g / 3 tbsp unsalted butter , melted
- 1 tbsp olive oil
- 2 garlic cloves , finely minced
- 1/2 tsp each salt and pepper
OPTIONAL FINISHING FLAVOUR:
-
- 1 1/2 tbsp lemon juice
- 1 tsp fresh thyme leaves (parsley also good for colour)
Instructions
- Preheat oven to 220°C/450°F (200°F fan).
- Toss mushrooms with butter, oil, garlic, salt and pepper in a large bowl using a rubber spatula.
- Spread on a baking tray and roast for 25 minutes – do not toss or turn.
- Remove from oven. If using lemon and thyme, push mushrooms together onto one side of the tray, drizzle with lemon, sprinkle with thyme and toss. Serve immediately!
HOW TO ROAST LARGE MUSHROOMS (EG PORTABELLO)
- 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).
