How to Make Vegetable Stuffed Portabella Mushrooms
Preheat your oven to 375 °F (190 °C). Line a sided baking sheet with parchment paper for easy cleanup and to prevent sticking.
Scoop out the gills of the portabella mushrooms gently with a small spoon. Remove the stalk carefully using a small knife, creating space for the delicious stuffing.
Coat each mushroom with a drizzle of olive oil, ensuring they are well covered. Place them on the prepared baking sheet, stalk side up, ready for filling.
Saut the diced sweet onion in a 12-inch saut pan over medium-high heat with a splash of olive oil for about 3 to 4 minutes. Then, add the diced zucchini and cook until it begins to soften, about another 2-3 minutes.
Add the diced roasted red pepper and chopped sun-dried tomatoes to the pan. Continue cooking until the onions are translucent and soft. Then, throw in the minced garlic and cook for one more minute. Finally, stir in the handful of spinach until wilted.
Mix all the cooked veggies together and remove from heat. Gently fold in the dried breadcrumbs, grated Parmesan, and seasonings until everything is well combined.
Stuff each mushroom generously with one portion of the vegetable mixture, pressing down lightly to fit as much as possible.
Bake the stuffed mushrooms in the oven for 35 to 40 minutes. Afterward, add about 1 tablespoon of shredded mozzarella on top of each mushroom and bake for another 10 to 12 minutes, or until the cheese is golden and bubbly.
Optional: Garnish with fresh herbs like basil or parsley before serving for an extra pop of flavor.
