Ingredients

  • Fresh mushrooms: button, cremini, shiitake, portobello (8 cups, sliced)
  • Olive oil (3 tbsp)
  • Garlic cloves (4, minced)
  • Onion (1 medium, thinly sliced)
  • Fresh thyme (1 tsp) or dried thyme (1/2 tsp)
  • Salt and pepper to taste
  • Butter (2 tbsp, optional for richness)
  • Mayonnaise or vegan mayo (1/4 cup)
  • Dijon mustard (1 tbsp)
  • Cheese slices: Swiss, cheddar, or vegan cheese (4 slices)
  • Sandwich bread: ciabatta, sourdough, or whole grain (8 slices)
  • Fresh spinach or arugula (1 cup)
  • Tomato slices (1 medium tomato, sliced)
  • Balsamic vinegar (1 tbsp, optional for tang)
  • Red pepper flakes (optional, for a spicy kick)

Equipment

  • Large skillet or frying pan
  • Cutting board and sharp knife
  • Spoon or spatula for stirring
  • Mixing bowl
  • Toaster or grill pan
  • Measuring spoons and cups
  • Plate for assembling sandwiches

Instructions

  1. Prepare the mushrooms: Clean and slice your mushrooms evenly. This ensures they cook uniformly and absorb the flavors better.
  2. Cook the aromatics: Heat 2 tablespoons of olive oil and the butter (if using) in a large skillet over medium heat. Add minced garlic and sliced onions. Sauté until onions turn translucent and garlic is fragrant, about 3-4 minutes.
  3. Sauté mushrooms: Add the sliced mushrooms to the skillet. Sprinkle with fresh thyme, salt, and pepper. Cook for 8-10 minutes, stirring occasionally, until mushrooms are browned and any released liquid has evaporated.
  4. Add balsamic vinegar (optional): Drizzle balsamic vinegar over the mushrooms and stir for 1-2 minutes to add a tangy sweetness that enhances depth of flavor.
  5. Toast the bread: While mushrooms cook, lightly toast your bread slices in a toaster or on a grill pan until golden and slightly crispy.
  6. Prepare sandwich spread: In a small bowl, mix mayonnaise with Dijon mustard. Spread this mixture evenly on one side of each toasted bread slice.
  7. Assemble the sandwich: Layer the sautéed mushrooms generously on four slices of the bread. Top with cheese slices, tomato slices, and fresh spinach or arugula. Sprinkle red pepper flakes if you want some heat.
  8. Grill the sandwich: Place the other bread slices on top, mayo side down. Heat the sandwich in the skillet or grill pan for 2-3 minutes on each side, pressing gently, until cheese melts and bread is crispy.
  9. Serve immediately: Cut sandwiches in half and serve warm with your favorite side.

Tips & Variations

“For the best flavor, use a mix of mushroom varieties like cremini and portobello to create a more complex umami profile.”

  • Vegan alternative: Use vegan mayo and plant-based cheese. Add avocado slices for creamy texture.
  • Spicy twist: Add sliced jalapeños or a dash of hot sauce to the mayo spread.
  • Herb variations: Try fresh rosemary or oregano in place of thyme for a different herbal aroma.
  • Cheese options: Swap Swiss for mozzarella, gouda, or blue cheese depending on your preference.
  • Extra crunch: Add pickled onions or crispy fried shallots for texture contrast.
  • Make it a melt: Add sliced bell peppers and use a panini press to get a melty, pressed sandwich.
