Ingredients
  

  • 4 large portobello mushrooms
  • 1 cup quinoa
  • 2 cups vegetable broth or water
  • 2 tablespoons olive oil
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 2 cups fresh spinach, chopped
  • 1/2 cup feta cheese, crumbled
  • 1/4 cup sun-dried tomatoes, chopped
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • Salt and pepper, to taste
  • 1/4 cup grated Parmesan cheese optional
  • Fresh parsley, chopped for garnish

Method
 

Preparing the Quinoa
  1. To begin, focus on cooking the quinoa. This protein-rich grain is a perfect stuffing for portobello mushrooms, as it complements the mushrooms’ earthy flavor.
  2. Rinse the quinoa: Start by rinsing 1 cup of quinoa under cold water using a fine mesh strainer. Rinsing helps remove quinoa’s natural coating, called saponin, which can taste bitter if not washed off.
  3. Cook the quinoa: In a medium-sized pot, combine the rinsed quinoa and 2 cups of vegetable broth (or water). Bring it to a boil over medium-high heat. Once it reaches a boil, reduce the heat to low, cover the pot, and let it simmer for about 15 minutes, or until the liquid is fully absorbed.
  4. Fluff the quinoa: Once cooked, remove the pot from the heat and let it sit, covered, for 5 minutes. After that, fluff the quinoa with a fork to separate the grains. Set it aside to cool slightly.
Preparing the Portobello Mushrooms
  1. While the quinoa is cooking, you can start preparing the portobello mushrooms.
  2. Clean the mushrooms: Gently clean each mushroom with a damp paper towel to remove any dirt. Avoid rinsing them under water, as mushrooms can absorb moisture and become soggy.
  3. Remove the stems and gills: Carefully remove the stems from the mushrooms by twisting them off. Next, using a small spoon, scoop out the gills from the underside of each mushroom cap.
  4. This step is important because the gills can release excess moisture during cooking, which may make the stuffing soggy.
  5. Prepare the mushrooms for stuffing: Drizzle the mushroom caps with 1 tablespoon of olive oil and season them lightly with salt and pepper. Place the mushrooms on a baking sheet, gill side up, and set them aside.
Making the Filling
  1. Now, it’s time to prepare the flavorful quinoa filling.
  2. Sauté the onion and garlic: In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the finely chopped onion and cook for about 3–4 minutes, or until the onion becomes translucent. Then, add the minced garlic and cook for another 1–2 minutes, stirring frequently to prevent the garlic from burning.
  3. Add the spinach: Stir in the chopped spinach and cook until it wilts, which should take about 2–3 minutes. If your skillet is too small to hold all the spinach at once, add it in batches.
  4. Combine the quinoa: Once the spinach is wilted, add the cooked quinoa to the skillet. Mix everything together until well combined.
  5. Season the mixture: Stir in the dried oregano, dried basil, chopped sun-dried tomatoes, and crumbled feta cheese. Season the mixture with salt and pepper to taste. Cook the mixture for another 2–3 minutes, allowing the flavors to meld together. Remove the skillet from the heat.
Stuffing and Baking the Mushrooms
  1. With the filling ready, it’s time to stuff and bake the portobello mushrooms.
  2. Stuff the mushrooms: Using a spoon, carefully fill each mushroom cap with the quinoa mixture. Pack the filling tightly to ensure the mushrooms are generously stuffed. If you like, you can sprinkle a little grated Parmesan cheese on top of each stuffed mushroom for an extra layer of flavor.
  3. Bake the mushrooms: Preheat your oven to 375°F (190°C). Once heated, place the baking sheet with the stuffed mushrooms in the oven. Bake for 20–25 minutes, or until the mushrooms are tender and the tops are lightly browned.
