These Garlic Butter Roasted Mushrooms are one of my favorite side dishes when I need something quick, low-effort, and full of deep, savory flavor. Roasted in a rich garlic butter sauce, they come out tender, juicy, and caramelized—perfect alongside steak, chicken, pasta, or even served on toast.
Why You’ll Love This Recipe
I like this recipe because it’s incredibly easy to prepare and takes minimal attention once it’s in the oven. The mushrooms soak up all that buttery, garlicky goodness and develop a rich umami flavor with slightly crisp edges. I can serve them as a side dish or pile them on top of grains or salads for a more complete meal. It’s simple, satisfying, and always delivers.
Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
- Whole mushrooms (button or cremini)
- Butter, melted
- Garlic, minced
- Olive oil (optional, for extra richness)
- Fresh parsley, chopped (for garnish)
- Salt
- Black pepper
- Optional: lemon juice, thyme, or Parmesan
Directions
- I preheat my oven to 400°F (200°C).
- I clean the mushrooms by gently wiping them with a damp paper towel—no rinsing, since they absorb water quickly.
- In a large mixing bowl, I toss the mushrooms with melted butter, minced garlic, salt, and pepper until well coated. I sometimes add a splash of olive oil for extra richness.
- I spread the mushrooms out in a single layer on a baking sheet or in a roasting dish.
- I roast for 20–25 minutes, stirring once halfway through, until the mushrooms are golden, tender, and slightly crispy around the edges.
- I finish them off with a sprinkle of fresh parsley and a squeeze of lemon juice for brightness, if I have it.
- I serve them warm as a side dish or topping.
Servings and timing
This recipe serves about 4 as a side dish. It takes me around 5 minutes to prep and 25 minutes to roast, so it’s ready in just 30 minutes from start to finish.
Variations
I like adding fresh thyme or rosemary to the roasting pan for a fragrant twist. Sometimes I stir in a spoonful of grated Parmesan in the last 5 minutes of roasting for a cheesy upgrade. If I’m serving it with pasta or toast, I drizzle a little balsamic reduction on top for an extra punch.
storage/reheating
Leftover mushrooms keep well in the fridge for up to 3 days. I reheat them in a skillet over medium heat to bring back their roasted texture, or in the oven at 375°F (190°C) for 8–10 minutes. I avoid microwaving if possible—it softens them too much.
FAQs
Can I use sliced mushrooms?
Yes, I can, but whole mushrooms hold their shape better and stay juicier. Sliced mushrooms roast faster and can dry out, so I watch the timing closely.
What kind of mushrooms work best?
I usually go for white button or cremini mushrooms—they roast well and soak up the butter and garlic beautifully. Portobello chunks also work if I want something meatier.
Can I make this dairy-free?
Yes, I use a plant-based butter alternative or all olive oil for a dairy-free version. It’s still rich and flavorful.
Do I need to line the baking sheet?
It’s not required, but I sometimes use parchment paper for easier cleanup. A roasting dish also works well and helps catch all the buttery juices.
Can I prep these in advance?
I mix the mushrooms with the butter and garlic and store them in the fridge for a few hours before roasting. I just bring them to room temperature before they go into the oven.
Conclusion
Garlic Butter Roasted Mushrooms are the kind of recipe I can always count on—fast, full of flavor, and endlessly versatile. Whether I’m serving them with dinner or piling them onto something simple like toast or rice, they never fail to impress. It’s a low-maintenance dish that brings a lot to the table.
