Chestnut mushrooms have quickly become one of my regular mushrooms to cook with – they’ve got a nutty flavor and a firmer, meatier bite than button mushrooms. A short sauté in garlic butter is truly all they need!

Why you’ll love this unfussy mushroom recipe

I first picked up chestnut mushrooms on a whim at the farmers market, not genuinely knowing what to expect, and they’ve since earned a regular spot in my mushroom rotation right alongside shiitakes and oyster mushrooms.

Why You’ll Love This:

Simply a handful of ingredients – butter, garlic, and a splash of wine is all it takes.
Ready in 15 minutes – a fast, low-effort side dish for any busy-night meal.
Earthy, nutty taste – chestnut mushrooms have a distinct taste that’s more complex than white button mushrooms.
Firm, meaty texture – their unique texture hold their shape beautifully instead of turning mushy.

A Note on the Name “Chestnut Mushrooms”

The name “chestnut mushroom” can be a little confusing, since it’s used for more than one type of mushroom. The variety in this dish is Pholiota adiposa, sometimes also sold as “cinnamon cap” mushrooms since it’s the same species simply marketed under different names. To add to the mix-up, in some UK grocery stores “chestnut mushroom” actually refers to brown cremini mushrooms, which are a completely different species with a different texture and flavor, and in parts of North America the name has occasionally been used for pioppino mushrooms or even baby portobellos.

So if a recipe or store label says “chestnut mushroom,” it’s always worth double-checking which one you’re actually working with – this method is built around the true Pholiota adiposa variety.

Chestnut Mushrooms Ingredients

The simple ingredients for this dish are listed fully down in the recipe card but let’s briefly go over what’s needed including a few substitutions you can make as desired!

Chestnut mushrooms – small mushrooms that grow in dense clusters with a chestnut brown cap, firm texture, and a nutty flavor; trim the tough base of the cluster before cooking.
Butter – creates a rich, caramelized coating as the mushrooms cook.
Olive oil – helps prevent the butter from burning at higher heat.
Garlic – adds savory depth; stir it in near the end so it doesn’t burn.
White wine – optional, but it adds a nice depth of flavor as it deglazes the pan.
Fresh thyme – an earthy, aromatic finishing touch that pairs perfectly with the mushrooms.
Salt and black pepper – added at the end to bring all the flavors together.

How to Make It

Simply a reminder that you can find the FULL written recipe down in the recipe card, but I want to quickly go over how to make them with visuals for you:) If this is your first time making chestnut mushrooms, I promise it’s so unfussy!

Prep the mushrooms. Trim off the tough base where the cluster was attached, then separate or slice the mushrooms as desired. Wipe clean with a damp cloth rather than rinsing.

Sear. Melt butter and olive oil in a large skillet over medium-high heat. Add the mushrooms in a single layer and let them cook undisturbed for 3-4 minutes to develop a deep golden crust. Stir and cook for another 2-3 minutes, until the mushrooms are caramelized all over.

Finish and serve. Pour in the white wine, if using, and let it bubble and reduce for about a minute. Stir in the garlic and fresh thyme and cook for 1 more minute, simply until fragrant.
Season with salt and pepper to taste and serve warm.

Recipe Tips

Don’t overcrowd the pan – give the mushrooms space in a single layer so they sear instead of steam.
Let them sit undisturbed – resisting the urge to stir early on is what gives you that deep caramelization.
Add the garlic late – it burns quickly, so stir it in during the last minute of cooking.
Skip the rinse – mushrooms soak up water easily, which can make them chewy instead of caramelized.
