Ingredients

  • 2 cups baby bella mushrooms quartered
  • 2 tablespoons olive oil
  • 2 tablespoons butter
  • sea salt to taste
  • 1 teaspoon garlic powder or four cloves fresh garlic minced
  • ¼ cup teriyaki sauce use storebought or homemade, add extra if you like your mushrooms saucy
  • green onion tops chopped for garnish

Homemade Teriyaki Sauce (optional)

Instructions

  • Clean and trim mushrooms. Gather all of your ingredients.
  • Heat oil and butter in skillet over medium heat until shimmering or a drop of water flicked in it dances.
  • Sprinkle salt and garlic powder into pan with butter and oil and add mushrooms.
  • Sauté mushrooms until golden, about 4-5 minutes, taking care that butter doesn’t burn.
  • Lower heat and pour in teriyaki sauce. Continue cooking a few minutes longer to allow sauce to thicken slightly. When they're ready to serve, top with green onions.

Teriyaki Sauce (optional)

  • In a small saucepan combine soy sauce, sugar, ginger, and garlic. In a small bowl combine mirin and cornstarch. Stir until cornstarch is dissolved.
  • Next, add the cornstarch mixture to the soy mixture. Bring sauce to boil over medium-high heat, stirring occasionally. Then reduce your heat and simmer, stirring occasionally, until sauce is reduced and becomes syrupy, between 6 and 7 minutes.
  • Add honey and stir. Taste to see if you want to add more honey. My husband prefers a sweeter teriyaki sauce than I do! Add more honey if you prefer!

Notes

  • Roast Instead of Sautéing: For a hands-off option, roast the mushrooms. Toss them with melted butter, olive oil, and seasonings, then spread in a single layer on a baking sheet. Roast at 400–425°F for 15–18 minutes, adding the teriyaki sauce during the last 5 minutes to finish.
  • Use a Hot Pan: Heat your skillet before adding mushrooms. A hot surface encourages browning and helps lock in flavor.
  • Give Them Space: Avoid overcrowding the pan. Cook in batches if needed so the mushrooms brown instead of steam.
  • Let Them Sit: Once in the pan, don’t stir too much. Letting mushrooms sit undisturbed helps them develop a nice caramelized edge.
