Juicy sauteed mushrooms and onions are the best side dish! They take minutes to cook, taste irresistible, and pair with just about anything.


  • 16 ounces baby bella (aka cremini) mushrooms*
  • 1 yellow onion
  • 3 tablespoons olive oil or butter
  • 1 tablespoon Worcestershire sauce (or use vegan or this substitute)
  • 1 tablespoon fresh lemon juice
  • 1/2 teaspoon kosher salt, plus more for seasoning
  • Fresh ground black pepper


  1. Clean the mushrooms, then slice them. Slice the onion
  2. In a saute pan or skillet, heat the olive oil over medium high heat. Add the onion for 2 minutes, then mushrooms and cook for 2 minutes, stirring often (the mushrooms will start to release their liquid). Add the kosher salt and pepper and Worcestershire sauce and cook another 4 to 5 minutes, stirring occasionally, until most of the liquid is cooked out and the mushrooms are tender (taste to assess doneness).
  3. Add the lemon juice and stir, cooking another 30 seconds to 1 minute until evaporated. Taste and add a few pinches or salt until the flavor pops. Leftovers store up to 3 days refrigerated; reheat over medium heat in a skillet.


*Substitute button mushrooms if you can’t find cremini.
