Creamy Garlic Butter White Mushrooms – Easy 30-Minute Side

By September 16, 20268 min read

I still remember the first time my mom let me stir the mushrooms at the stove. I was maybe nine, standing on a little wooden stool, watching the pale buttons turn deep golden brown in butter. That smell, garlic and butter and earthy mushrooms, is basically the smell of home to me.

White mushrooms get a bad rap for being bland, but that is only because people crowd the pan or drown them too early. Give them room, let them brown, and finish them in a creamy garlic sauce, and suddenly everyone at the table is asking for seconds.

This is my go-to recipe when I need a side that feels fancy but takes almost no effort. It works next to steak, roast chicken, pasta, or even a big pile of toast for a cozy meatless dinner.

About the Ingredients

1 1/2 lbs (680g) white button mushrooms, wiped clean and halved or quartered if large

Buy mushrooms that are firm, dry, and evenly white with tightly closed caps. Cremini mushrooms are a great substitute and give a slightly deeper, earthier flavor.

3 tablespoons (42g) unsalted butter, divided

If you only have salted butter, cut the added salt in half. Olive oil can replace one tablespoon of butter for a higher smoke point.

2 tablespoons olive oil

Regular or light olive oil works fine here. Avocado oil is a good substitute if you want an even higher smoke point for browning.

4 cloves garlic, minced (about 1 tablespoon)

Fresh garlic gives the best flavor, but 1 teaspoon garlic powder can stand in if you are out. Add garlic powder with the cream instead of early so it does not burn.

1/2 cup (120ml) heavy cream

For a lighter version, use half-and-half or full-fat coconut milk. Whole milk works too but the sauce will be thinner, so simmer it a minute longer.

1/4 cup (25g) grated Parmesan cheese

Pecorino Romano or aged Asiago are tasty substitutes. Use freshly grated cheese rather than the shaker kind for a smoother melt.

1/2 teaspoon kosher salt, plus more to taste

Kosher salt is more forgiving than table salt. If using fine table salt, start with 1/4 teaspoon and adjust at the end.

1/4 teaspoon freshly cracked black pepper

Freshly cracked pepper tastes brighter than pre-ground. A pinch of red pepper flakes adds a nice gentle heat if you like.

1 tablespoon fresh parsley, chopped, for garnish

Flat-leaf parsley is best for flavor, but curly parsley works for looks. Fresh thyme or chives are lovely substitutes.

Tips & Tricks

Do not crowd the pan

Mushrooms release a lot of water, so cook them in a single layer in two batches if needed. Crowding steams them instead of browning them.

Wait for the golden sear

Let the mushrooms sit undisturbed for a few minutes before stirring. That untouched contact with the hot pan is what builds the deep, savory flavor.

Add cream off the boil

Lower the heat before pouring in the cream so it does not split. A gentle simmer keeps the sauce silky and smooth.

Pro Tips

1

Pat mushrooms completely dry with a paper towel before cooking so they sear instead of steam.
2

Save the mushroom stems for stock or chop them finely and add them with the caps for zero waste.
3

Finish with a squeeze of lemon juice to brighten the buttery, creamy sauce right before serving.
4

Grate the Parmesan on a microplane so it melts instantly into the sauce without clumps.

Step-by-Step Instructions

1. Prep the mushrooms

Wipe the mushrooms clean with a damp paper towel and trim the stem ends. Halve or quarter any large ones so all pieces are roughly the same size for even cooking.

2. Sear in butter and oil

Heat 2 tablespoons butter and the olive oil in a large skillet over medium-high heat (375F / 190C). Add the mushrooms in a single layer and cook 6 to 8 minutes without stirring until the undersides are deeply golden brown and the edges look crisp.

3. Season and flip

Sprinkle the salt and pepper over the mushrooms, then stir and cook another 4 to 5 minutes until they are tender and glossy and most of the released liquid has evaporated.

4. Add the garlic

Push the mushrooms to one side of the pan and add the remaining 1 tablespoon butter with the minced garlic. Cook 30 to 45 seconds until fragrant, then stir the garlic into the mushrooms so it does not burn.

5. Build the cream sauce

Reduce the heat to medium-low (300F / 150C) and pour in the heavy cream. Simmer gently for 2 to 3 minutes, stirring, until the sauce thickens enough to coat the back of a spoon.

6. Melt in the Parmesan

Stir in the grated Parmesan and cook 1 minute more until the sauce is smooth and bubbling at the edges. Taste and add more salt or pepper if needed.

7. Garnish and serve

Scatter the chopped parsley over the top and serve hot straight from the pan. These mushrooms are best enjoyed right away while the sauce is glossy and warm.

Delicious Variations

Marsala Mushrooms

Swap the cream for 1/2 cup dry Marsala wine and simmer until reduced and syrupy for a rich, restaurant-style side.

Spicy Chili Garlic Mushrooms

Add 1/2 teaspoon red pepper flakes with the garlic and finish with a drizzle of chili oil for a bold, zesty kick.

Vegan Coconut Cream Mushrooms

Use olive oil instead of butter and full-fat coconut milk instead of cream, and skip the Parmesan for a dairy-free version.

How to Store White Mushroom Recipes: Creamy Garlic Butter Mushrooms

Refrigerator

Store leftovers in an airtight container in the refrigerator for up to 3 days. The sauce will thicken as it chills, which is totally normal.

Freezer

Freezing is not ideal because the cream sauce can separate, but if needed, freeze in a sealed container for up to 1 month and thaw overnight in the fridge.

Reheating

Reheat gently in a skillet over medium-low heat (300F / 150C) with a splash of cream or water, stirring until the sauce is smooth and hot.

Frequently Asked Questions

Q: How do I keep white mushrooms from getting soggy?

Cook them in a single layer over medium-high heat and do not stir until they are golden brown. Crowding the pan traps steam, which makes mushrooms release water and turn rubbery instead of searing.

Q: Can I use cremini or portobello mushrooms instead of white button mushrooms?

Yes, cremini and baby portobello mushrooms are excellent substitutes and add a slightly deeper flavor. Just cut them into similar-sized pieces so they cook at the same rate.

Q: How do I make this creamy mushroom recipe dairy-free?

Use olive oil in place of butter and full-fat coconut milk or a dairy-free cream alternative instead of heavy cream. Skip the Parmesan or use a dairy-free grated cheese, and taste for salt before serving.

Q: What goes well with creamy garlic butter mushrooms?

They pair beautifully with steak, roast chicken, pork chops, pasta, polenta, or crusty toast. They also work as a topping for burgers or baked potatoes.

Q: Can I make this recipe ahead of time?

You can prep and sear the mushrooms up to a day ahead and refrigerate them. When ready to serve, reheat in a skillet and add the cream and Parmesan fresh so the sauce stays silky.
