Grilled Portobello Mushrooms with Garlic Sauce

This recipe features portobello mushrooms marinated in a mix of garlic, balsamic vinegar, and spices before being grilled or pan-cooked to tender perfection. They are served with a creamy smoky garlic sauce made from blended sautéed onion, garlic, soaked cashews, and seasoning. The sauce has optional nutritional yeast for cheesiness and can be served over pasta for a complete meal. The mushrooms absorb the marinade flavors while cooking, resulting in a meaty texture complemented by the rich, flavorful sauce.

Instructions

    Cup of Yum
  1. In a shallow dish, mix all the ingredients under marinade. Place the portobello mushrooms in the dish and brush the marinade all over, Let it marinade for 10 to 15 minutes.
  2. Heat a grill or a heavy bottom pan over medium heat. Spray or brush oil on the pan. When hot, place the mushrooms on the pan, partially cover and cook for 3 to 4 minutes per side. If the the mushrooms are thin, they will cook through in the time. If they are thick, transfer to the oven and bake at 400 degrees F for 15 minutes or until a knife goes through easily. To Bake the marinated mushrooms without grill step, bake for 25 to 30 minutes in the shallow dish.
  3. Make the sauce: Heat oil in a skillet over medium heat. Add onion and garlic and pinch of salt and cook until translucent.
  4. Transfer half of the mixture to a blender. Add the rest of the ingredients and blend until smooth. Blend a couple of times of 1 minute cycles so the cashews blend in.
  5. Pour the blended mixture into the skillet with the remaining onion garlic and cook over medium heat until thickened. Taste and adjust salt and flavor. Add a dash of thyme and a tsp of vegan worcestershire or soy sauce for additional flavor if needed. 
  6. Serve the mushrooms drizzled generously with the creamy sauce, fresh basil (adds great flavor) and black pepper. 

Notes

  • For a gluten-free version, use tamari instead of Worcestershire sauce.
  • If avoiding cashews, substitute with soaked macadamia nuts, pumpkin seeds, flour, or mashed cauliflower and potatoes for thickening.
  • This dish can be served as a standalone or tossed with cooked pasta for a complete meal.
  • Adjust the amount of white wine or vinegar in the sauce to suit your taste or omit as desired.
