Step-by-Step Instructions
Follow these detailed instructions to create perfectly grilled stuffed portobello mushroom caps:
**1. Prepare the Mushrooms:**
* **Clean the Mushrooms:** Gently wipe the portobello mushroom caps with a damp paper towel to remove any dirt or debris. Avoid soaking them in water, as they will absorb it and become soggy.
* **Remove the Stems:** Carefully remove the stems from the mushrooms. You can twist them off or use a small knife to cut them out. Save the stems; they can be chopped and added to the filling.
* **Remove the Gills (Optional):** Some people prefer to remove the dark gills from the underside of the mushroom caps. This is mainly for aesthetic reasons and can prevent the filling from becoming discolored. To remove the gills, use a spoon to gently scrape them away. If you don’t mind the appearance, you can leave the gills intact, as they are edible and add to the flavor.
* **Marinate the Caps (Optional):** While not strictly necessary, marinating the mushroom caps can enhance their flavor and prevent them from drying out on the grill. In a small bowl, whisk together 2 tablespoons of olive oil, 2 cloves of minced garlic, a pinch of salt, and a pinch of black pepper. Brush this mixture over the inside and outside of the mushroom caps. Let them marinate for at least 15 minutes, or up to an hour, at room temperature.
**2. Prepare the Filling:**
* **Cook the Sausage:** In a large skillet over medium heat, heat 1 tablespoon of olive oil. Add the Italian sausage (removed from its casing) and cook, breaking it up with a spoon, until it is browned and cooked through. If using plant-based sausage, follow the package instructions for cooking.
* **Sauté the Vegetables:** Add the chopped onion and red bell pepper to the skillet with the sausage. Cook until the vegetables are softened, about 5-7 minutes. Add the remaining 2 cloves of minced garlic and cook for another minute until fragrant.
* **Add the Spinach and Mushroom Stems:** If using fresh spinach, add it to the skillet and cook until it wilts. If using frozen spinach, make sure it is thawed and squeezed dry before adding it to the skillet. Add the chopped mushroom stems (if using) and cook for a few more minutes until they soften.
* **Combine the Filling Ingredients:** Remove the skillet from the heat. In a large mixing bowl, combine the cooked sausage and vegetable mixture, breadcrumbs, Parmesan cheese, half of the mozzarella cheese (reserve the other half for topping), chopped fresh basil, dried oregano, red pepper flakes (if using), salt, and black pepper. Mix well to combine all the ingredients. Taste and adjust the seasoning as needed.
**3. Stuff the Mushroom Caps:**
* **Fill the Caps:** Spoon the filling evenly into the prepared portobello mushroom caps, pressing it down gently to pack it in. Mound the filling slightly on top of the caps.
**4. Grill the Stuffed Mushrooms:**
* **Preheat the Grill:** Preheat your grill to medium heat (about 350-400°F or 175-200°C). Make sure the grill grates are clean and lightly oiled to prevent sticking.
* **Grill the Mushrooms:** Place the stuffed mushroom caps directly on the grill grates, filling-side up. If you are concerned about the filling falling out, you can use a grill basket or place the mushrooms on a sheet of aluminum foil. Close the grill lid and cook for about 15-20 minutes, or until the mushrooms are tender and the filling is heated through and slightly browned.
* **Add the Cheese:** During the last few minutes of grilling, sprinkle the remaining mozzarella cheese over the filling. Close the grill lid and continue cooking until the cheese is melted and bubbly.
**5. Serve and Enjoy:**
* **Remove from the Grill:** Carefully remove the grilled stuffed portobello mushroom caps from the grill using a spatula. Let them cool slightly before serving.
* **Garnish and Serve:** Drizzle the stuffed mushrooms with balsamic glaze (optional) and garnish with fresh basil leaves. Serve them immediately as a main course or side dish.
Tips for Grilling Success
* **Choose the Right Mushrooms:** Select portobello mushroom caps that are firm, dry, and free of blemishes. Avoid mushrooms that are slimy or have a strong odor.
* **Don’t Overcrowd the Grill:** Grill the mushrooms in batches if necessary to avoid overcrowding the grill. Overcrowding can lower the grill temperature and prevent the mushrooms from cooking evenly.
* **Control the Heat:** Adjust the grill temperature as needed to prevent the mushrooms from burning. If the filling is browning too quickly, move the mushrooms to a cooler part of the grill or lower the heat.
* **Use a Grill Basket or Foil:** If you are concerned about the filling falling out, use a grill basket or place the mushrooms on a sheet of aluminum foil.
* **Check for Doneness:** The mushrooms are done when they are tender and the filling is heated through and slightly browned. You can test the tenderness of the mushrooms by piercing them with a fork.
* **Rest Before Serving:** Letting the mushrooms rest for a few minutes before serving allows the juices to redistribute, resulting in a more flavorful and moist dish.
Serving Suggestions
Grilled stuffed portobello mushroom caps are incredibly versatile and can be served in a variety of ways:
* **Main Course:** Serve two stuffed mushrooms per person as a satisfying vegetarian main course. Accompany them with a side salad, roasted vegetables, or a grain dish like quinoa or couscous.

* **Appetizer:** Cut the stuffed mushrooms into smaller pieces and serve them as an appetizer at a party or gathering.

Make-Ahead Tips
* **Prepare the Filling in Advance:** The filling can be prepared up to 24 hours in advance and stored in the refrigerator. Bring it to room temperature before stuffing the mushrooms.
* **Stuff the Mushrooms Ahead of Time:** The mushrooms can be stuffed up to a few hours in advance and stored in the refrigerator. Cover them tightly with plastic wrap to prevent them from drying out. Add the cheese just before grilling.
