Quinoa Stuffed Portobello Mushrooms: Step-by-Step Guide

Step 1: Cook the Quinoa
Start by rinsing the quinoa under cold water to remove any bitterness. In a large pot, combine the rinsed quinoa and water. Bring to a boil, then reduce the heat to low, cover, and simmer for about 15 minutes or until the quinoa is fluffy and the water is absorbed. Once done, remove from heat and let it sit covered for 5 minutes.
Step 2: Prepare the Portobello Mushrooms
Preheat your oven to 375°F (190°C). While the quinoa is cooking, prepare the portobello mushrooms by removing the stems and gently scraping out the gills with a spoon. This will create more space for the filling and allow the mushrooms to roast evenly. Place the caps on a baking sheet.
Step 3: Make the Filling
In a mixing bowl, combine the cooked quinoa, diced tomatoes, bread crumbs, chopped basil, and half of the feta cheese. Drizzle in the olive oil and balsamic vinegar, then season with black pepper, crushed red pepper flakes, and salt to taste. Mix everything thoroughly until well combined.
Step 4: Stuff the Mushrooms
Spoon the quinoa mixture generously into each portobello cap, pressing down slightly to pack them in. Top each stuffed mushroom with the remaining feta cheese for added flavor and creaminess.
Step 5: Bake
Bake the stuffed mushrooms in the preheated oven for 20-25 minutes, or until the mushrooms are tender and the tops are golden. The aroma will fill your kitchen, making it hard to resist.
Step 6: Serve and Enjoy
Remove from the oven and let them cool for a few minutes before serving. These quinoa stuffed portobello mushrooms can be enjoyed warm or at room temperature, making them a versatile option for any meal.
Variations for Dietary Needs

If you have specific dietary needs or preferences, consider these variations:
- Gluten-Free: Use gluten-free breadcrumbs or omit them entirely.
