  • 12 large button mushrooms
  • 1 cup potatoes , cooked (or leftover mashed potatoes)
  • 4 Tbsp olive oil
  • cup onion , chopped
  • 2 cloves garlic , crushed
  • cup breadcrumbs (we used our easy Sprouted Breadcrumbs recipe)
  • 2 Tbsp fresh basil , chopped
  • ½ tsp salt
  • 1 lemon , juiced


  1. Preheat oven to 350℉ and set aside sprouted breadcrumbs. If you don’t have sprouted breadcrumbs on hand, prepare a batch using our trusty recipe.
  2. With an electric mixer, whip the cooked potatoes with 2 tablespoons of olive oil. Stir in salt, basil, and lemon juice. Set aside.
  3. Clean mushrooms and pull off the stems. Chop the stems. In a medium skillet, sauté the onions, mushroom stems, and garlic with 1 tablespoon of olive oil just until softened. Add to cooked potatoes.
  4. Place mushroom caps, cups facing upward, on a cookie sheet. Spoon potato mixture into each cap. Toss breadcrumbs with a tablespoon of olive oil and sprinkle on top of each mushroom. Bake for 20 – 25 minutes until mushrooms are tender and the filling is golden. Enjoy!

  • Don’t have fresh basil? Dried basil works fine too. You can use whichever combination of fresh or dried herbs you prefer (thyme, rosemary, oregano, or sage would be equally delicious!)
  • If you have leftover mashed potatoes in your fridge, use them in this recipe to save time.
