Ingredients for Garlic Butter Mushrooms

Here’s everything you need to make this steakhouse-style side dish:

• 1½ lbs cremini or white button mushrooms (cleaned and trimmed)
• 4 tablespoons unsalted butter
• 2 tablespoons olive oil
• 5 garlic cloves, minced
• 1 tablespoon soy sauce or Worcestershire sauce (for umami boost)
• 1 teaspoon fresh thyme or rosemary (or ½ tsp dried)
• Salt and black pepper to taste
• 1 tablespoon chopped fresh parsley (for garnish)

Optional Add-ins:

• Splash of white wine or balsamic vinegar
• Parmesan cheese for finishing
• Red pepper flakes for heat

How to Clean Mushrooms Properly

Proper cleaning is key to flavorful and non-soggy mushrooms:

• Wipe with a damp paper towel or soft brush to remove dirt.
• Avoid soaking them in water, as mushrooms absorb moisture and become mushy.
• Trim off the woody stems if using larger cremini or portobello mushrooms.

Step-by-Step Instructions

Step 1: Prep the Mushrooms

Clean and trim mushrooms. Slice in halves or quarters if large, or leave whole for small mushrooms.

Step 2: Heat the Pan

Heat olive oil and 2 tablespoons of butter in a large skillet over medium-high heat.

Step 3: Sauté the Mushrooms

Add mushrooms in a single layer. Let them cook undisturbed for 3–4 minutes to develop color, then stir and continue cooking until browned and tender (about 8–10 minutes total).

Step 4: Add Garlic and Herbs

Reduce heat to medium. Add minced garlic, thyme, and remaining butter. Stir constantly for 1–2 minutes until garlic is fragrant but not burnt.

Step 5: Add Umami Boosters

Stir in soy sauce or Worcestershire sauce. Cook another minute to let flavors meld.

Step 6: Season and Serve

Season with salt and pepper to taste. Garnish with chopped parsley and serve immediately.

• Let them sear before stirring to develop deep flavor.
• Use a combination of butter and oil to prevent burning.

While cremini and button mushrooms are most common, here are other great options:

• Portobello mushrooms (for a meaty texture)
• Shiitake mushrooms (earthy and rich)
• Oyster mushrooms (delicate and flavorful)
• Baby bella mushrooms (a mature version of button mushrooms)
