Ingredients

Scale
  • 16 oz fresh mushrooms (white button or cremini), cleaned and trimmed
  • 6 tbsp unsalted butter, softened
  • 4 large cloves garlic, minced
  • 1 tbsp freshly squeezed lemon juice
  • 2 tbsp fresh parsley, finely chopped
  • 1 tsp Dijon mustard
  • 1/2 tsp crushed red pepper flakes (optional)
  • 1/2 tsp smoked paprika
  • 1/2 tsp salt, or to taste
  • 1/4 tsp freshly ground black pepper
  • 1 tbsp olive oil

Instructions

  1. Wipe mushrooms clean with a damp towel. Trim ends if needed and slice large mushrooms in half for even cooking.
  2. In a mixing bowl, combine softened butter, minced garlic, lemon juice, chopped parsley, Dijon mustard, red pepper flakes, smoked paprika, salt, and black pepper. Mix until creamy and uniform. Adjust seasoning to taste.
  3. Heat a large skillet over medium-high heat. Add olive oil and let it heat until shimmering.
  4. Add mushrooms to the skillet in a single layer. Cook undisturbed for 2-3 minutes to brown, then stir and cook for another 3-4 minutes until most liquid evaporates and mushrooms are golden-brown. Work in batches if needed.
  5. Reduce heat to medium. Add cowboy butter to the skillet with mushrooms. Stir gently until butter melts and coats mushrooms, forming a glossy sauce. Scrape up any browned bits from the pan.
  6. Once mushrooms are tender and sauce has thickened slightly, remove from heat. Taste and adjust salt or lemon juice if needed. Garnish with extra parsley and serve hot.

Notes

For best browning, avoid overcrowding the pan—work in batches if necessary. Cowboy butter can be made ahead and refrigerated. For extra flavor, add a splash of white wine or chicken broth before the butter. Use plant-based butter for a dairy-free or vegan version. Mushrooms are best served hot, but leftovers keep well for up to 4 days in the fridge.
