Deeply caramelized cremini mushrooms, tender on the inside with beautifully browned edges, are finished in rich butter with delicate shallots, fragrant garlic, and fresh thyme. A splash of dry sherry brings out their earthy character, while a touch of lemon juice balances the richness. The secret is allowing the mushrooms to release their moisture before adding fat, creating a deeply savory, restaurant-quality side dish without a heavy sauce.

Ingredients

• 1 pound cremini mushrooms, cleaned and quartered or cut into thick slices
• 1 tablespoon neutral cooking oil, such as avocado oil
• 2 tablespoons unsalted butter, divided
• 1 small shallot, finely minced
• 2 cloves garlic, finely minced
• 1 teaspoon fresh thyme leaves
• 1 tablespoon dry sherry, optional
• 1/2 teaspoon kosher salt, or to taste
• 1/4 teaspoon freshly ground black pepper
• 1 teaspoon freshly squeezed lemon juice, optional
• Fresh thyme leaves, for garnish, optional

Instructions

1. Prepare the mushrooms. Remove any visible dirt with a soft brush or briefly rinse the mushrooms under cool running water. Pat thoroughly dry. Quarter smaller mushrooms and cut larger mushrooms into thick, evenly sized slices.
2. Preheat the skillet. Place a 12-inch cast-iron or heavy stainless-steel skillet over medium heat. Allow it to warm for approximately 2 minutes. The skillet should be hot enough to encourage evaporation without scorching the mushrooms.
3. Release the moisture. Add the mushrooms directly to the dry skillet, without oil or butter. Spread them into a relatively even layer. If the skillet is overcrowded, cook in batches.
4. Cook off the liquid. Cook for approximately 5–8 minutes, stirring occasionally, as the mushrooms begin releasing moisture. Continue until most of the liquid has evaporated and the mushrooms begin making a more pronounced sizzling sound.
5. Begin browning. Add the neutral oil and increase the heat slightly to medium-high if necessary. Spread the mushrooms evenly across the skillet and leave them undisturbed for approximately 2–3 minutes, allowing the undersides to develop a deep golden-brown color.
6. Brown the remaining surfaces. Turn the mushrooms and continue cooking for another 2–4 minutes, until several surfaces are attractively browned. Reduce the heat if the mushrooms begin scorching.
7. Add the shallot and butter. Reduce the heat to medium. Add 1 tablespoon of butter and the minced shallot. Cook for approximately 1 minute, stirring gently, until the shallot begins to soften.
8. Add the aromatics. Stir in the garlic and fresh thyme. Cook for 30–60 seconds, just until fragrant. Avoid allowing the garlic to brown excessively.
9. Deglaze the skillet. If using dry sherry, pour it into the skillet and scrape up any flavorful browned bits with a wooden spoon. Allow the liquid to simmer until nearly evaporated, approximately 30–60 seconds.
10. Finish with butter. Add the remaining tablespoon of butter, kosher salt, and freshly ground black pepper. Toss gently until the butter melts and coats the mushrooms with a light, glossy finish.
11. Balance the flavor. Remove the skillet from the heat. Add the lemon juice, if desired, and taste. Adjust the salt and pepper as necessary.
12. Serve immediately. Transfer the mushrooms to a warmed serving dish or present them directly in the cast-iron skillet. Garnish sparingly with fresh thyme leaves.

Cook’s Notes

• The secret to browning: Allowing the mushrooms to release and evaporate their moisture before adding fat encourages more effective browning and concentrates their natural flavor.
• Avoid overcrowding: Mushrooms need sufficient contact with the skillet for a golden crust to develop. Cook in batches if necessary.
• Choosing mushrooms: Cremini mushrooms provide excellent flavor and texture, but white button mushrooms also work well. For a more complex flavor, substitute 1/4 pound of the cremini with fresh shiitake caps.
• Butter timing: Adding butter toward the end preserves its rich flavor while reducing the likelihood of burning the milk solids.
• Dry sherry: Choose a dry drinking sherry rather than a salted cooking sherry. If preferred, substitute a tablespoon of unsalted chicken or vegetable stock.
• Salt: Season after the moisture-release stage for greater control over the final flavor.
• Make-ahead preparation: Clean and cut the mushrooms several hours in advance, then refrigerate until ready to cook. For the best browned texture, sauté immediately before serving.

Serving Suggestions

Steaks and grilled meats: Serve alongside a perfectly seared ribeye, filet mignon, or New York strip. The mushrooms’ savory flavor complements the richness of beef.

Pork chops: Pair with Bourbon-Glazed Thick-Cut Pork Ribeye Chops for a satisfying steakhouse-style dinner.

Roasted chicken: Spoon the mushrooms alongside herb-roasted chicken or chicken breast for a simple, elegant accompaniment.

Mashed potatoes: Serve over creamy mashed potatoes, allowing the buttery mushroom juices to mingle with the potatoes.

Pasta and risotto: Fold into freshly cooked pasta or spoon over Parmesan risotto for additional savory depth.

Toast or crostini: Spoon the warm mushrooms over toasted sourdough or crusty country bread for a rustic appetizer.

Beverage Suggestions

Dry red wine: Pinot Noir or a lighter-bodied Merlot pairs well with the mushrooms’ earthy character.

Dry white wine: Chardonnay or Sauvignon Blanc complements the butter, garlic, and thyme.

Sparkling water with lemon: A refreshing nonalcoholic choice that balances the richness of the butter.

Unsweetened iced tea: A classic accompaniment, particularly when serving the mushrooms with grilled meats.

Sparkling apple cider: Its gentle acidity and fruit character provide a pleasant contrast to the savory mushrooms.

Storage and Reheating

Refrigeration: Allow the mushrooms to cool briefly, then transfer to an airtight container and refrigerate within 2 hours. Use within 3–4 days.

Reheating: Warm in a skillet over medium heat with a small amount of butter until thoroughly heated. Avoid adding excessive liquid, which can soften the browned surfaces.

Freezing: Cooked mushrooms may be frozen for up to 2 months for best quality, although their texture may become softer after thawing. They are particularly suitable for sauces, soups, and gravies after freezing.

Variations

Steakhouse-Style Mushrooms: Omit the lemon juice and finish with an additional teaspoon of butter and a few drops of Worcestershire sauce.

Garlic-Parmesan Mushrooms: Omit the sherry and finish with 2 tablespoons of freshly grated Parmesan cheese after removing the skillet from the heat.

Creamy Mushroom Finish: Stir in 1 tablespoon of crème fraîche after removing the skillet from the heat for a lightly creamy coating.

Japanese-Inspired Butter-Soy Mushrooms: Omit the sherry and thyme. Finish with 1 teaspoon of Japanese soy sauce, unsalted butter, and finely sliced scallions. Reduce the added salt to account for the soy sauce.

Mixed Wild Mushroom Variation: Replace half the cremini mushrooms with a combination of oyster, shiitake, and king oyster mushrooms. Cook in batches as necessary to accommodate their different sizes and textures.
