  • 4 large portobello caps
  • 1 1/2 tablespoons whole grain Dijon mustard, plus more for serving, if you like
  • 2 tablespoons olive oil
  • 1 tablespoon white wine vinegar
  • 1 tablespoon maple syrup
  • 1 garlic clove, minced
  • Salt and pepper to taste
  • 4 burger buns
  • Toppings of choice
  1. Clean the mushrooms and remove the stems. Scrape out the gills with a spoon.

  2. Whisk the Dijon mustard, olive oil, vinegar, maple syrup and garlic together in a small bowl. Taste-test and adjust any seasonings to your liking.

  3. Brush the Dijon mixture all over the outsides of the mushroom caps. Reserve any extra.

  4. To bake: Preheat the oven to 400°. Arrange the mushrooms on a baking sheet, stem sides up, and bake for 10-12 minutes, until tender.

  5. To grill: Lightly oil your grill and build a medium flame. Place the mushrooms directly on the grill and cook for about 4 minutes on each side, until slightly charred and tender.

  6. Remove the mushrooms from the oven or grill and allow them to cool for a few minutes. Sprinkle with salt and pepper to taste.

  7. Stuff the mushrooms into buns and top with any reserved sauce or additional Dijon mustard and toppings of choice. Serve.
