how to make mushrooms like they do at mastros

If you've ever savored the rich, buttery mushrooms at Mastro's, you know they're a standout side dish that elevates any meal. Recreating this restaurant favorite at home is easier than you might think, requiring just a few key ingredients and techniques. The secret lies in using a combination of high-quality mushrooms, such as cremini or button mushrooms, sautéed in a generous amount of butter and olive oil until they develop a deep, golden-brown sear. Garlic, fresh thyme, and a splash of white wine or chicken broth add depth and flavor, while a final touch of heavy cream or parmesan cheese creates a luxurious, velvety finish. With the right balance of ingredients and a bit of patience, you can achieve that signature Mastro's mushroom magic in your own kitchen.

Selecting Mushroom Varieties: Choose firm, fresh mushrooms like cremini or button for best texture and flavor

The foundation of Mastro’s signature mushrooms lies in the selection of the right variety. Cremini and button mushrooms are the stars here, prized for their firm texture and earthy flavor that holds up to high-heat cooking. Unlike delicate varieties like shiitake or oyster, which can wilt or become rubbery, cremini and button mushrooms retain their structure, making them ideal for searing to a golden brown. Their mild, umami-rich taste also acts as a perfect canvas for absorbing buttery, garlicky flavors without overpowering the dish.

When shopping, prioritize freshness above all else. Look for mushrooms with smooth, unblemished caps and firm stems. Avoid any with slimy surfaces or dark spots, signs of age and spoilage. A quick squeeze test is your best tool: a fresh mushroom should feel dense and spring back slightly when pressed. If it’s soft or spongy, it’s past its prime. For optimal results, use mushrooms within 2–3 days of purchase, storing them in a paper bag in the refrigerator to maintain their dryness and prevent moisture buildup.

While cremini and button mushrooms are the top choices, don’t be afraid to experiment with blends for added depth. Mixing in a small portion of baby bella mushrooms, a darker, more mature version of cremini, can enhance the dish’s savory profile. However, keep the ratio balanced—too many larger varieties can dominate the texture and flavor. The goal is to maintain the firm, biteable consistency that Mastro’s mushrooms are known for, so always ensure the majority of your selection is cremini or button.

Finally, consider the cooking method when selecting your mushrooms. Since Mastro’s-style mushrooms are typically seared in a hot pan with butter and garlic, the variety’s natural moisture content matters. Cremini and button mushrooms have just enough moisture to create a rich, glossy coating without becoming waterlogged. This makes them superior to higher-moisture varieties like portobello, which tend to release excess liquid and steam instead of caramelizing. By choosing the right mushroom, you set the stage for that coveted golden crust and tender interior.

Preparing the Pan: Use a hot skillet with high-smoke oil (e.g., avocado or grapeseed) for searing

A sizzling skillet is the foundation of Mastro’s signature mushroom dish. The key lies in harnessing the power of high heat and the right oil. Avocado or grapeseed oil, with smoke points above 400°F, are ideal for searing without burning. This ensures a deep, golden crust forms on the mushrooms, locking in moisture and intensifying flavor. Think of it as the culinary equivalent of a tanning bed—controlled heat for maximum impact.

Preheating the skillet is non-negotiable. Aim for medium-high heat, allowing the pan to reach a temperature where a drop of water sizzles and evaporates instantly. This initial blast of heat jumpstarts the Maillard reaction, the chemical process responsible for that irresistible umami-rich browning.

The oil’s role extends beyond heat tolerance. Its neutral flavor profile lets the earthy essence of the mushrooms shine. Unlike olive oil, which can impart a fruity note, avocado or grapeseed oil act as silent partners, enhancing without overshadowing. Think of them as the stage crew, ensuring the star of the show—the mushrooms—gets all the attention.

While the urge to crowd the pan might be strong, resist. Overcrowding leads to steaming, not searing. Give each mushroom ample space to caramelize, allowing hot air to circulate and moisture to escape. This ensures even browning and prevents a soggy, lackluster result.

Finally, patience is paramount. Once the mushrooms hit the pan, let them be. Resist the urge to stir or flip prematurely. Allow the heat to work its magic, creating a beautiful crust before gently turning them over. This initial sear is crucial for achieving the textural contrast Mastro’s mushrooms are known for—crispy exterior, tender interior.

Seasoning Tips: Season mushrooms generously with salt, pepper, and garlic for Mastro’s signature taste

The secret to Mastro’s signature mushroom flavor lies in the bold, unapologetic use of seasoning. Salt, pepper, and garlic aren’t mere afterthoughts—they’re the backbone of the dish. Think of them as the power trio that transforms ordinary mushrooms into a rich, savory side worthy of a steakhouse. The key is generosity; Mastro’s doesn’t skimp, and neither should you. A light sprinkle won’t cut it—these mushrooms demand a confident hand with the salt shaker and garlic press.

Let’s break it down. Start with salt, the unsung hero of flavor enhancement. Aim for 1 teaspoon of kosher salt per pound of mushrooms. This might sound excessive, but mushrooms are like sponges, absorbing only what they need. Salt not only seasons but also draws out excess moisture, ensuring a firmer texture and deeper browning. Next, pepper—freshly ground, not pre-packaged. Add ½ teaspoon per pound for a subtle heat that complements the earthiness of the mushrooms. Finally, garlic, the game-changer. Use 3-4 minced cloves per pound, or go rogue with a full head if you’re feeling adventurous. Sauté the garlic in butter or olive oil before adding the mushrooms to infuse the dish with its aromatic essence.

Now, a cautionary note: timing matters. Add the garlic too early, and it burns; too late, and it loses its punch. Toss it in after the mushrooms have started to brown, letting it cook just until fragrant—about 1-2 minutes. This ensures a balanced flavor without bitterness. Similarly, season in stages. Don’t dump all the salt at once; add half at the beginning to help release moisture, then the rest toward the end to amplify the taste.

The takeaway? Mastro’s mushrooms aren’t about complexity—they’re about confidence. Embrace the simplicity of salt, pepper, and garlic, but apply them with intention. The result? Mushrooms that are boldly seasoned, deeply flavorful, and undeniably craveable. It’s not just a side dish; it’s a masterclass in how three basic ingredients can steal the show.

Cooking Technique: Sear mushrooms undisturbed until golden brown, then flip for even cooking

The secret to achieving that coveted Mastro’s mushroom texture lies in patience and precision. When searing mushrooms, resist the urge to stir or flip them prematurely. Allow them to sit undisturbed in a hot pan with a generous amount of butter or oil—at least 2 tablespoons for every 8 ounces of mushrooms. This ensures even contact with the heat source, promoting deep browning and caramelization. The goal is to develop a golden-brown crust that locks in flavor and creates a satisfying contrast between the crispy exterior and tender interior.

Consider the science behind this technique: undisturbed searing allows moisture to evaporate from the mushrooms, concentrating their umami-rich flavor. Flipping too early traps steam, leading to soggy, grayish results instead of the desired golden sear. Use medium-high heat to strike a balance—high enough to brown without burning, but not so intense that the mushrooms cook unevenly. For best results, use a heavy-bottomed skillet like cast iron or stainless steel, which distributes heat more evenly than nonstick pans.

A common mistake is overcrowding the pan, which lowers the temperature and causes steaming instead of searing. Work in batches if necessary, ensuring each mushroom has ample space to cook. Once the first side is deeply browned—typically after 3–5 minutes—flip the mushrooms using tongs to avoid piercing their delicate flesh. Cook the second side for another 2–3 minutes, just until golden. This two-sided approach ensures even cooking and maximizes flavor development.

For a Mastro’s-inspired finish, deglaze the pan with a splash of wine or broth after removing the mushrooms, scraping up the flavorful browned bits (fond) left behind. Pour this sauce over the mushrooms to add depth and moisture. Season aggressively with salt, pepper, and fresh herbs like thyme or parsley to enhance the earthy notes. Serve immediately while the mushrooms are warm and crisp, pairing them with steak, pasta, or a rich risotto for a restaurant-quality dish.

Mastering this searing technique transforms ordinary mushrooms into a decadent side or centerpiece. The key takeaway? Let time and heat work their magic, flipping only when necessary to achieve that perfect golden crust. With practice, you’ll replicate the Mastro’s experience in your own kitchen, proving that sometimes, the best results come from doing less, not more.

Finishing Touches: Add butter, herbs (thyme or parsley), and a splash of wine for richness

A well-executed mushroom dish relies on a delicate balance of flavors, and the finishing touches are where the magic happens. At Mastro's, the addition of butter, herbs, and wine transforms simple mushrooms into a decadent side dish. To replicate this, start by selecting high-quality, unsalted butter – approximately 2 tablespoons per pound of mushrooms. This will provide a rich, velvety base without overwhelming the natural earthy flavors.

The choice of herbs is crucial, as it can either enhance or overpower the dish. Thyme offers a subtle, woodsy aroma, while parsley brings a bright, fresh note. For a Mastro's-inspired dish, finely chop 1 teaspoon of fresh thyme or 1 tablespoon of flat-leaf parsley per pound of mushrooms. Add the herbs during the last minute of cooking to preserve their delicate flavors and vibrant colors. A splash of wine, about 2-3 tablespoons, should be added just before the mushrooms finish cooking. This allows the alcohol to evaporate, leaving behind a rich, complex flavor without any harsh notes.

Consider the type of wine used, as it will significantly impact the final taste. A dry white wine, such as a Sauvignon Blanc or Pinot Grigio, will add a crisp, acidic note, while a red wine like Pinot Noir will contribute a deeper, more robust flavor. For a truly luxurious dish, opt for a high-quality wine that you would enjoy drinking. The cooking process will concentrate the flavors, so choose a wine that complements the mushrooms and herbs.

To achieve the perfect finishing touch, follow these steps: after the mushrooms have cooked for 8-10 minutes, add the butter and allow it to melt, creating a rich, glossy sauce. Next, sprinkle in the chopped herbs, stirring gently to combine. Finally, pour in the wine, and let the mixture simmer for 1-2 minutes, until the liquid has reduced slightly. This technique will ensure that the flavors meld together seamlessly, creating a dish that rivals the mushrooms served at Mastro's. By paying attention to these details, you can elevate your mushroom dish from ordinary to extraordinary.

The key to mastering this technique lies in understanding the interplay between ingredients. Butter provides richness, herbs add depth, and wine contributes complexity. When combined in the right proportions and at the right time, these elements create a harmonious flavor profile. For best results, use fresh, high-quality ingredients and adjust the quantities based on personal preference. A slightly larger quantity of butter or wine can be used for a more indulgent dish, while a lighter touch will allow the mushrooms' natural flavors to shine. With practice and attention to detail, you can recreate the luxurious mushroom dish that has made Mastro's a favorite among diners.
