Main Instructions

  • Heat a large skillet over medium heat. Melt the butter and sauté the chopped onion until soft and translucent.
  • Add the finely chopped garlic and stir for about 1 minute until fragrant.
  • Stir in the sun-dried tomato strips and 1 tablespoon of their oil. Cook for 2 minutes to release flavor.
  • Add the mushrooms and sauté for 5–7 minutes until browned and tender.
  • Deglaze the pan with 2–3 tablespoons of vegetable broth or water, scraping up any browned bits. Let it reduce slightly.
  • Lower the heat to medium-low. Pour in the heavy cream and let it simmer gently, stirring occasionally.
  • Season with salt and pepper to taste. Stir in the baby spinach and cook until wilted.
  • Add the grated parmesan cheese and stir until it melts into the sauce.
  • Stir in the Italian herbs and, if a thicker sauce is desired, add the cornstarch-water mixture. Cook for another 1–2 minutes.
  • Garnish with chopped parsley and serve hot.

Notes

  • For the best mushroom flavor, don’t overcrowd the pan. Cook in batches if necessary.
  • You can use cremini, button, or mixed mushrooms.
  • Store leftovers in the fridge for up to 3 days and reheat gently over low heat.
  • Not suitable for freezing due to the cream-based sauce.
