Learn how to make the best steak house mushrooms with simple ingredients, less oil, less splatter, and perfectly browned beefy and juicy mushrooms just like the restaurants.
To clean the mushrooms, use a clean paper towel to gently wipe off any dirt. Trim the stems. Halve any larger mushrooms and leave the smaller ones whole.
Start with a large cold sauté pan or a 12-inch cast-iron skillet. Add the mushrooms and ¼ cup room-temperature water. Cook over medium-high heat until the water evaporates and the mushrooms start to brown, about 8 minutes. Stir occasionally so all the mushrooms make contact with the water and brown evenly.
While the mushrooms cook, combine the shallot, garlic, thyme, salt, and pepper in a small bowl.
Add the olive oil to the pan. Continue cooking over medium-high heat, stirring occasionally, until the mushrooms are deeply browned, about 4 minutes.
Push the mushrooms to one side of the pan and add the butter to the center. Once melted, add the garlic, shallot, thyme, and the salt-and-pepper mixture to the center of the pan. Sauté until the shallots are lightly browned, about 1 minute.
Deglaze with the Worcestershire sauce and cook for 1 minute. Add the chicken broth, stir everything together, and let the broth reduce by about half, around 2 minutes. Turn off the heat.
Transfer the mushrooms to a serving bowl or platter. Season with a few grinds of black pepper and extra salt to taste. Garnish with a few thyme leaves and serve warm.

Notes
Tip for Even Cooking: Choose mushrooms that are similar in size so they cook at the same rate. Whole mushrooms hold their shape better, brown more evenly, and stay juicy.
Storage & Reheat: Store leftovers in an airtight container for up to 4 days. They taste great at room temperature, or microwave on medium for about 1 minute until warm.
