Equipment

  • 1 Skillet (medium or large) – for sautéing vegetables
  • 1 Spoon or Cookie Scoop – to portion filling
  • 1 Baking Dish (9x13 or similar) – for baking mushrooms
  • 1 Cutting Board & Knife – for chopping shallots, garlic, and mushroom stems
  • 1 Mixing Spoon or Silicone Spatula – to stir tofu mixture smoothly

Ingredients
  

  • 24 large cremini mushrooms stems removed and cleaned
  • 1 medium shallot finely chopped
  • 2 garlic cloves minced
  • 4 ounces frozen chopped spinach thawed and drained
  • 1 teaspoon sea salt
  • ½ teaspoon ground black pepper
  • 8 ounces silken tofu
  • ¼ cup nutritional yeast
  • ¼ cup gluten-free breadcrumbs

Instructions
 

  • Preheat the Oven: Set your oven to 400°F (200°C). This gives it time to reach the right temperature while you prepare the filling and mushrooms.
  • Prepare the Mushrooms: Gently twist and remove the stems from each mushroom, setting aside half of the stems. Wipe the mushroom caps with a damp paper towel to clean them. Finely mince the reserved stems and discard the rest.
  • Sauté the Filling Base: In a medium skillet over medium heat, warm a splash of oil or a tablespoon of water. Add the minced mushroom stems, chopped shallot, minced garlic, and drained spinach. Sprinkle in the salt and pepper. Sauté for about 5 minutes, stirring often, until the vegetables are soft and fragrant.
  • Incorporate the Tofu and Seasoning: Add the silken tofu and nutritional yeast directly into the skillet. Stir well until the tofu breaks down and everything is evenly combined. You should have a creamy, well-blended mixture with flecks of spinach throughout.
  • Fill the Mushroom Caps: Place the cleaned mushroom caps, gill-side up, into a large baking dish or sheet pan lined with parchment. Using a spoon or small cookie scoop, fill each mushroom generously with the tofu-spinach mixture.
  • Top with Crunchy Breadcrumbs: Evenly sprinkle the gluten-free breadcrumbs over each filled mushroom. This adds a crisp topping during baking.
  • Bake to Perfection: Transfer the baking dish to the oven and roast the mushrooms for 20 to 25 minutes, until they appear softened and begin to release juices.
  • Broil for a Golden Finish: Switch your oven to the broil setting and broil the mushrooms for an additional 4–5 minutes, or until the breadcrumbs turn golden brown and slightly crisp on top. Keep a close eye during this step to avoid burning.
  • Serve Warm: Carefully remove from the oven and let cool for a few minutes. Serve immediately while warm and flavorful.

Notes

  • Make Ahead Tip: The filling can be prepared up to 24 hours in advance and refrigerated. Stuff and bake the mushrooms just before serving.
  • Fresh vs. Frozen Spinach: Frozen spinach is convenient, but fresh spinach can be used if chopped and wilted in the pan beforehand.
  • Tofu Texture: Silken tofu provides a creamy consistency. Avoid using firm or extra-firm tofu as it won’t blend smoothly.
  • Breadcrumb Options: For a grain-free option, try almond flour or crushed gluten-free crackers as a topping substitute.
  • Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or air fryer to maintain texture.
