Ingredients

  • 2 tbsp extra-virgin olive oil divided
  • 24 oz whole baby portobello mushrooms (cremini) or button-around 24 small, or 12 large portobello mushrooms
  • ¼ cup sun-dried tomatoes very finely chopped (I buy these in a bag and rehydrate them in warm water) or you can use the marinated ones in olive oil *see notes
  • ½ cup sweet onion finely chopped
  • 1 cup Parmesan cheese freshly shredded
  • ½ tsp fresh cracked pepper
  • ½ tsp paprika
  • 1 tbsp fresh basil finely chopped or ½ tsp dried basil
  • 1 lb Italian sausage mild, medium, or hot (your heat preference🔥)
  • *Optional: chopped fresh parsley or basil for garnish

Instructions

  • Preheat your oven to 375 degrees F.
  • Prepare your mushrooms by removing the stems and scooping out the gills and a little of the center to make room for your stuffing.
  • Chop the stems finely and save to add to the stuffing
  • Heat 1 tbsp olive oil in a large skillet over medium heat. Saute the sausage until it's no longer pink.
  • Add the onions and mushroom stems and sauté until the onions are translucent and soft.
  • Add in all other ingredients and stir until the cheese just begins to melt, then remove from the heat.
  • Fill the mushroom caps with the mixture and drizzle the tops with the remaining olive oil.
  • Bake for about 30 minutes until the stuffing begins to brown.
  • Garnish with fresh parsley or basil, if desired. You can even grate a little extra freshly grated Parmesan on top right before serving.

Notes

  • If you use sun-dried tomatoes in oil, make sure to drain and pat them dry before chopping.
  • To clean the mushrooms, wipe them down thoroughly with a damp paper towel rather than rinsing them under running water, so they stay as dry as possible. If there's an excess of moisture, your stuffed mushroom may become soggy.
  • For small mushrooms, use a heaping tablespoon each.
