Garlic Herb Roasted Mushrooms

I was rummaging through the fridge on a rainy Tuesday when I spotted a container of mushrooms I'd forgotten about. They needed using, and I had garlic, olive oil, and a few sprigs of thyme wilting in a jar on the windowsill. Twenty minutes later, the kitchen smelled so good my neighbor knocked to ask what I was making.

The first time I made these for friends, I served them on toasted sourdough as a last minute appetizer. Everyone kept circling back to the tray, and one person even asked if I'd catered. I didn't have the heart to tell them it was just mushrooms and whatever herbs I had left.

Ingredients

• Cremini or button mushrooms: Cremini have a deeper, earthier flavor, but button mushrooms work beautifully too and crisp up just as nicely when roasted.
• Olive oil: This is what helps the mushrooms caramelize and turn golden, so don't skimp on it or they'll steam instead of roast.
• Garlic cloves: Fresh garlic is key here, it mellows and sweetens in the oven and clings to every mushroom like a savory glaze.
• Fresh parsley: It brightens everything up at the end, though I've swapped in basil or chives when that's what I had on hand.
• Fresh thyme and rosemary: These woodsy herbs make the whole dish smell like a cozy kitchen in the countryside, dried versions work in a pinch but use less.
• Sea salt and black pepper: Simple seasonings that let the mushrooms and garlic shine without competing for attention.
• Lemon juice: A quick squeeze at the end cuts through the richness and makes everything taste a little brighter and more alive.

Instructions

Preheat and prep:

Get your oven up to 220°C (425°F) and line a baking sheet with parchment paper. This high heat is what gives the mushrooms those crispy, caramelized edges.

Toss everything together:

In a big bowl, throw in the mushrooms, olive oil, garlic, parsley, thyme, rosemary, salt, and pepper. Use your hands to toss them around until every piece is shiny and coated.

Spread them out:

Lay the mushrooms in a single layer on the baking sheet, making sure they're not crowded. If they're too close, they'll steam instead of roast.

Roast until golden:

Pop them in the oven for 18 to 20 minutes, giving them a stir halfway through. You'll know they're ready when the edges are browned and the garlic smells toasty.

Finish and serve:

Pull them out, drizzle with a bit of lemon juice if you like, and toss gently. Transfer to a serving dish, sprinkle on a few extra herbs, and serve them while they're still hot.

I started keeping a bag of mushrooms in the fridge after I realized how often I needed a quick side dish that felt special. These have saved me more times than I can count, from weeknight dinners to impromptu gatherings when I needed something that looked and tasted impressive without any real planning.

Flavor Variations

Once you've made the basic version, you can play around with it endlessly. I've stirred in a pinch of chili flakes for heat, grated Parmesan over the top right when they come out of the oven, and even swapped the thyme for oregano when I wanted something more Mediterranean. Each version feels like a different dish.

Serving Suggestions

These mushrooms are incredibly versatile. I've piled them onto toasted baguette slices, tossed them with pasta and a splash of pasta water, and served them alongside roasted chicken or steak. They also make a fantastic topping for polenta or risotto when you want something earthy and satisfying.

Storage and Reheating

Leftovers keep in the fridge for up to three days in an airtight container. I like to reheat them in a hot skillet rather than the microwave so they stay a bit crispy, though honestly they're also delicious cold, straight from the fridge, stirred into a grain bowl or salad.

• If you're meal prepping, roast a double batch and use them throughout the week.
• They freeze surprisingly well, just thaw and reheat in the oven to bring back some of that roasted texture.
• Don't add the lemon juice until you're ready to serve, it keeps them fresher longer.

There's something quietly satisfying about pulling a tray of golden, fragrant mushrooms out of the oven and knowing you turned a handful of simple ingredients into something this good. I hope they become as much of a go to for you as they have for me.
