This is a simple and delicious recipe for grilled stuffed mushrooms. Portobello mushrooms work really well for this recipe—because of their large size and shape, they will not slip through the grates of your grill. You can vary the number of mushrooms depending on the size. While this recipe calls for four large portobellos, you can use eight to 12 medium-size mushrooms instead.

Serve these as an appetizer, side, or main dish. If they're going to be the main dish, serve the stuffed mushrooms whole along with fresh salad greens or a side dish of choice. To make this recipe vegan, use olive oil or margarine instead of butter, and omit the cheese on top or use a vegetarian cheese or sprinkle it with nutritional yeast flakes.

The portobello mushroom is simply a more mature cremini mushroom—the common white mushroom you see in your supermarket. Left to grow a few more days, it can grow very large and develop more flavor. Always choose mushrooms that are firm and avoid any that are limp, shriveled, or slippery.

Ingredients

  • 4 large portobello mushrooms
  • 1/4 cup panko breadcrumbs

Recipe Variation
