Ingredients
  

  • 1 pound mushrooms whole if small, sliced if larger
  • 1 large sweet onion sliced
  • 3 Tablespoons butter salted or unsalted, adjust added salt accordingly
  • 3 Tablespoons worcestershire sauce
  • salt to taste
  • freshly ground black pepper to taste

Instructions
 

  • Melt butter in skillet over medium high heat taking care to not let your butter start to brown.
  • Add sliced onions and worcestershire sauce and cook, stirring occasionally for 3-4 minutes or until edges start to get a little brown.
  • Add mushrooms and cook additional 5-8 minutes depending on the size of the mushrooms and your preference for doneness. Whole mushrooms will take the longest.
  • Salt and pepper to taste.

Notes

  • We love baby bella mushrooms in this recipe, but simple white (button) mushrooms are also delicious. You could also try this recipe with sliced portobellos!
  • If you can find Georgia-grown Vidalia onions, of course we prefer them because they are just so sweet! If they're out of season, though, just be sure to use any sweet onion variety. Red onions would not be good in this recipe.
