Cowboy Mushrooms transform humble white button mushrooms into a savory, garlicky side dish by sautéing them low and slow in a doubled batch of zesty cowboy butter—a compound butter packed with Dijon mustard, fresh herbs, lemon, and spices for bold, restaurant-style flavor. These golden-brown mushrooms soak up the buttery richness, emerging tender yet meaty after 20-22 minutes in the skillet, perfect alongside steaks, burgers, or roasted chicken for weeknight dinners or holiday spreads. Ready in under 30 minutes with minimal prep, they offer an umami-packed upgrade to any meal that guests devour straight from the pan.
