Melt butter in a saucepan on stove over medium heat. Add mushrooms into saucepan and toss in butter.

Sprinkle lemon pepper and beef bouillon onto coated mushrooms. Put lid on saucepan and let saute for 10-15 minutes.

Remove lid. Mushrooms will cook down, and turn a dark color. Allow mushrooms to cook for another 10 minutes uncovered to reduce down the liquid.

After ten minutes, mushrooms are ready. Serve hot and enjoy.
