Ingredients

  • 4 large portobello mushroom caps, stems removed and cleaned
  • 1 cup cooked quinoa (or brown rice for nuttier texture)
  • 1/2 cup finely chopped walnuts, toasted
  • 1 small onion, finely diced
  • 3 garlic cloves, minced
  • 1 cup baby spinach, roughly chopped
  • 1/2 cup sun-dried tomatoes, finely chopped
  • 1/4 cup fresh parsley, minced
  • 2 tablespoons nutritional yeast (for a cheesy umami boost)
  • 2 tablespoons olive oil, plus extra for brushing mushrooms
  • 1 teaspoon smoked paprika
  • Salt and freshly ground black pepper, to taste
  • Juice of half a lemon
  • Optional: 1/4 cup vegan parmesan or bread crumbs for topping

Step-by-Step Instructions

  1. preheat your oven to 400°F (200°C). Gently brush the portobello mushroom caps with olive oil on both sides and sprinkle lightly with salt and pepper. Set them gill side down on a baking sheet lined with parchment.
  2. Prepare the filling: heat 2 tablespoons olive oil in a skillet over medium heat. Add the diced onion and sauté until translucent, about 5 minutes. Stir in the minced garlic and cook another minute until fragrant.
  3. Incorporate the chopped sun-dried tomatoes, walnuts, and spinach. Cook, stirring gently, until the spinach wilts and the mixture is well combined, roughly 3 minutes.
  4. Transfer the mixture to a large bowl. Add the cooked quinoa, nutritional yeast, smoked paprika, fresh parsley, lemon juice, and season generously with salt and pepper. Stir thoroughly to blend all flavors into a cohesive filling.
  5. Spoon the filling generously into each mushroom cap, firmly pressing to pack the mixture in. If using vegan parmesan or bread crumbs,sprinkle a thin layer over the tops for an added golden crust.
  6. Bake in the preheated oven for 20-25 minutes, or until the mushrooms are tender and the stuffing is heated through with a slight crisp on top.
  7. Remove from the oven and let cool for 5 minutes before serving to allow flavors to meld perfectly.

Chef’s Notes & Tips for Success

  • For an extra depth of flavor, try incorporating finely chopped roasted red peppers or a splash of soy sauce into the filling.
  • To keep the mushrooms juicy, avoid over-baking; the key is tender but not dry portobellos.
  • Make the filling a day ahead to enhance flavor infusion-simply assemble and bake when ready.
  • Swap quinoa for farro or millet for a different texture while retaining the hearty profile.
  • To make it gluten-free, skip the breadcrumbs or use certified gluten-free bread crumbs as a topping.

Creative Serving Suggestions

These vegan stuffed portobellos shine when paired with a crisp green salad tossed in a bright lemon vinaigrette, or alongside a creamy avocado and herb dip for contrast. Garnish with finely chopped fresh parsley or microgreens for that fresh pop of color. For a festive touch, drizzle a balsamic reduction over each mushroom just before serving to add a sweet tangy finish that ties all the savory components together beautifully.
