Stuffed Portobello Mushrooms with Spinach and Goat Cheese

Here’s a great light vegetarian recipe that makes a wonderful appetizer or side dish to many grilled meats. This recipe can even be doubled and served as a delicious main dish. Portobello mushrooms are stuffed with spinach, goat cheese, walnuts, and onions. I made these mushrooms as a light dinner for Andrew and I after indulging in way too many heavy meals and sweet desserts over the past month. They tasted so great! The meaty portobello mushrooms are so flavorful and filling. If one of your New Year’s resolutions is to drop a few pounds, these mushrooms are certain to please. 🙂

Stuffed Portobello Mushrooms with Spinach and Goat Cheese

Printer Friendly Version


  • 10 portobello mushrooms (each 4 to 5 inches), stems removed and reserved, caps wiped clean
  • 4 tablespoons olive oil, divided
  • 1 1/4 teaspoon salt, divided
  • 12 ounces baby spinach (about 10 cups)
  • 2 tablespoons water
  • 2 large slices white sandwich bread, torn into quarters
  • 2 tablespoons unsalted butter
  • 2 medium onions, diced small (about 2 cups)
  • 4 medium garlic cloves, minced or pressed through garlic press (about 4 teaspoons)
  • 1/2 cup dry sherry
  • 2 tablespoons chopped fresh thyme leaves
  • 4 ounces goat cheese, crumbled (about 1 cup)
  • 1/4 cup heavy cream
  • 1 cup walnuts, toasted and roughly chopped
  • 2 teaspoons fresh lemon juice
  • Ground black pepper


  1. Adjust oven rack to upper-middle position, place rimmed baking sheet on rack, and heat oven to 400 degrees. Using sharp knife, cut 1/4-inch slits, spaced 1/2 inch apart, in crosshatch pattern on surface (non-gill side) of 8 mushrooms. Dice remaining 2 mushroom caps and reserved stems into 1/2-inch pieces; set aside (you should have about 3 cups).
  2. Brush both sides of caps with 2 tablespoons oil and sprinkle evenly with 1 teaspoon salt. Place caps, gill-side up, on preheated baking sheet. Roast until mushrooms have released some of their juices and begin to brown around edges, 8 to 12 minutes. Flip caps over and continue to roast until liquid has completely evaporated and caps are golden brown, 8 to 12 minutes longer. Remove mushrooms from oven and heat broiler.
  3. Meanwhile, place spinach and water in large microwave-safe bowl. Cover bowl with large dinner plate (plate should completely cover bowl and not rest on spinach). Microwave on high power until spinach is wilted and decreased in volume by half, 3 to 4 minutes. Remove bowl from microwave and keep covered 1 minute. Carefully remove plate and transfer spinach to colander set in sink. Using back of rubber spatula, gently press spinach against colander to release excess liquid. Transfer spinach to cutting board and roughly chop. Return spinach to colander and press again; Set aside.
  4. Pulse bread in the bowl of a food processor fitted with the metal blade until coarsely ground, about 16 one-second pulses (you should have about 11/2 cups). Heat 1 tablespoon oil and 1 tablespoon butter in 12-inch skillet over medium heat until butter is melted. Add bread crumbs and 1/4 teaspoon salt; cook, stirring frequently, until light golden brown, 5 to 8 minutes. Transfer crumbs to small bowl and wipe out skillet with paper towels.
  5. 5. Return now-empty skillet to medium-high heat, add remaining tablespoon oil, and heat until smoking. Add chopped mushrooms and cook without stirring for 2 minutes. Continue cooking, stirring occasionally, until lightly browned, 4 to 6 minutes longer. Transfer to medium bowl.
  6. Add remaining tablespoon butter and onions to skillet; cook, stirring occasionally, until onions are light brown, 5 to 6 minutes. Add garlic and cook until fragrant, about 30 seconds. Stir in sherry and cook until almost no liquid remains, 1 to 2 minutes. Reduce heat to low and stir in reserved cooked mushrooms, spinach, thyme, goat cheese, cream, and walnuts. Continue cooking until cheese is melted and vegetables are well coated, 1 to 2 minutes. Remove pan from heat, stir in lemon juice, and season with salt and pepper to taste.
  7. Flip caps, gill-side up, and distribute filling evenly among mushroom caps; top each with 2 tablespoons bread crumb mixture. Broil mushrooms until crumbs are golden brown, 1 to 3 minutes. Serve immediately.
