Ingredients You’ll Need
The beauty of this Garlic Butter Baked Mushrooms Recipe lies in its straightforward list of pantry-friendly ingredients. Every item plays a crucial role, from the mushrooms’ meaty texture to the garlic’s aromatic punch and the fresh herbs’ vibrant color and fragrance.
- 1 pound mushrooms: Brown button mushrooms work wonderfully for their firm texture that holds up well in the oven.
- 2 large cloves garlic (minced): Minced garlic ensures the buttery sauce is infused with deep, savory flavor throughout.
- 2 large garlic cloves (thinly sliced): Sliced garlic adds lovely texture and bursts of garlicky goodness on top.
- 2 tablespoons olive oil: Olive oil helps coat the mushrooms evenly while adding a subtle fruity richness.
- Salt and pepper: To taste; essential for uplifting and balancing the natural mushroom umami.
- 5 sprigs fresh thyme: Fresh thyme lends an earthy, slightly floral aroma that complements mushrooms perfectly.
- 2 tablespoons unsalted butter (diced): Butter melts into a luscious sauce creating a rich, silky finish.
- 1/2 lemon (juice only): Fresh lemon juice cuts through the richness and brightens every mouthful.
- 1/2 cup chopped parsley: Parsley adds a fresh, herbal note and a pop of beautiful green color.
How to Make Garlic Butter Baked Mushrooms Recipe
Step 1: Prep Your Oven and Mushrooms
Start by preheating your oven to 430°F (220°C). This high heat is key to roasting the mushrooms to a tender, slightly caramelized perfection without turning them soggy. Next, halve or quarter the mushrooms depending on their size so they cook evenly.
Step 2: Toss Mushrooms with Garlic and Olive Oil
In a 7×11 baking dish, combine the mushrooms with both the minced and sliced garlic along with the olive oil. Toss everything together to make sure each piece is lightly coated with oil and garlic, setting the foundation for maximum flavor in every bite.
Step 3: Season and Add Herbs
Generously season with salt and pepper to enhance the mushrooms’ natural flavors. Tuck the fresh thyme sprigs in between the mushrooms, so the herb infuses its delicate aroma throughout while baking.
Step 4: Scatter Butter Over the Top
Distribute the diced unsalted butter evenly over the mushrooms, allowing it to melt during roasting and create a rich, indulgent sauce that clings to every morsel.
Step 5: Bake to Tender, Juicy Perfection
Bake the mushrooms in the preheated oven for about 15 minutes. You’ll know they’re done when they become tender and the sauce starts bubbling up, packed with garlic and herb-infused buttery goodness.
Step 6: Finish with Lemon and Fresh Parsley
Remove the thyme sprigs from the dish, then toss the mushrooms gently with fresh lemon juice and chopped parsley. This final step adds a refreshing brightness and vibrant color that beautifully balances the rich baked flavors.
How to Serve Garlic Butter Baked Mushrooms Recipe

Garnishes
To make your dish stand out even more, sprinkle a little extra fresh parsley or a dusting of grated Parmesan cheese right before serving. A light drizzle of high-quality extra virgin olive oil can also add a luxurious touch and enhance the buttery notes.
Side Dishes
These Garlic Butter Baked Mushrooms pair stunningly well with grilled steaks, roasted chicken, or alongside creamy mashed potatoes. They work beautifully as a savory side at holiday meals or as a tasty topping for crusty bread or polenta.
Creative Ways to Present
For a crowd-pleasing appetizer, serve the mushrooms in small ramekins or on a platter garnished with lemon wedges. You could also turn this recipe into an elegant bruschetta topping or stuff large mushroom caps with the mix for a delicious twist.
Make Ahead and Storage
Storing Leftovers
Leftover Garlic Butter Baked Mushrooms keep well in an airtight container in the refrigerator for up to 3 days. The flavors meld even more, making for an easy reheat with equally delightful taste.
Freezing
If you want to keep them longer, freeze the mushrooms in a sealed container or freezer-safe bag for up to 2 months. Keep in mind the texture may soften slightly after freezing, but the flavor will remain rich and inviting.
Reheating
Reheat leftovers gently in a skillet over medium-low heat or in the oven at 350°F (175°C) until warmed through. Avoid microwaving if possible, as it can make the mushrooms a bit rubbery and less appealing.
FAQs
Can I use other types of mushrooms for this Garlic Butter Baked Mushrooms Recipe?
Absolutely! While brown button mushrooms are recommended for their firm texture, cremini, shiitake, or even portobello mushrooms can be delicious alternatives. Just adjust cooking time slightly if you use larger or more delicate varieties.
Is there a way to make this recipe vegan?
Yes! Substitute the unsalted butter with vegan butter or olive oil, and ensure your herb ingredients are fresh and free from animal products to enjoy a plant-based version without sacrificing flavor.
How do I prevent the mushrooms from becoming soggy?
High oven temperature and not overcrowding the baking dish are critical. Mushrooms release moisture as they cook, so giving them room helps them roast rather than steam, resulting in a better texture.
Can I prepare this dish ahead of time?
You can prep the mushrooms, garlic, oil, and herbs ahead by tossing them together and refrigerating for a few hours. However, bake them just before serving to enjoy the freshest texture and taste.
What can I add to enhance the flavor?
Adding a pinch of smoked paprika or a sprinkle of grated Parmesan right before baking lends an extra savory depth. You can also experiment with different herbs like rosemary or oregano for varied aroma profiles.
