Equipment

Ingredients

  • 4 tablespoons unsalted butter
  • 2 tablespoons olive oil
  • 6 cloves garlic, minced
  • 16 ounces mushrooms, sliced (we used a mixture of baby Bella and shiitake)
  • 4 medium yellow onions, thinly sliced
  • 2 teaspoons kosher salt (to taste, added gradually)
  • 2 teaspoons thyme, fresh (could use 1 teaspoon of dried)
  • ½ teaspoon coarse black pepper (or to taste)
  • 1 tablespoon honey (to taste)
  • 2 tablespoons Worcestershire sauce
  • 2 tablespoons balsamic vinegar
  • 4 ounces chicken broth (½ cup, could use white wine, beef, or vegetable broth)

Instructions

  • Add butter and olive oil to a dutch oven to melt over low heat. Once melted, add garlic and saute until fragrant, about 1 minute.
  • Increase to medium heat. Add in onions and mushrooms. Allow to cook down for about 5 minutes, and don't touch them at this time.
  • Season with salt, pepper, and thyme. Increase the heat to medium-high. Add in the Worcestershire sauce, honey, balsamic vinegar, and chicken broth. Toss to combine again, and stir every 5 minutes or so until there is no excess liquid in the pan and the mushrooms and onions have nice browned edges. This will take 45-50 minutes. Adjust seasonings to taste, and enjoy!
  • Store in an airtight container in the fridge for up to 5 days.

Notes

  • Make sure mushrooms are dried really well before cooking, as mushrooms are very absorbent and excess water will make it harder to achieve a nice golden brown crust. 
  • We do recommend using yellow or Vidalia onions for the sweetest flavor. Red onions can be used but they will give a slightly more bitter flavor. 
  • Chicken broth can also be substituted with beef broth (for a beefier flavor to accompany beef dishes), vegetable broth for vegetarians, or even white wine. 
  • Sweeten to taste. Vidalia onions (if used) are particularly sweet, so you may require less honey.
