Step‑by‑Step Instructions for Cheesy Stuffed Portobello Mushrooms

Step 1: Preheat Oven
Begin by preheating your oven to 375°F (190°C). While the oven is heating, line a baking sheet with parchment paper to prevent the stuffed mushrooms from sticking, ensuring an easy cleanup later. This temperature will provide an ideal setting for evenly cooking your Cheesy Stuffed Portobello Mushrooms, allowing the cheese to melt beautifully.

Step 2: Prepare Mushrooms
Next, take your Portobello mushrooms and carefully remove the stems. Use a spoon to scrape out the dark gills inside each cap, ensuring even cooking and reducing excess moisture. You’ll want the caps to be clean and ready for stuffing, showcasing their rich earthy color and texture for your Cheesy Stuffed Portobello Mushrooms.

Step 3: Season Caps
Once your mushrooms are prepped, brush the insides of each cap with olive oil, promoting a golden, flavorful crust as they bake. Sprinkle them with a generous pinch of salt and pepper, enhancing the umami flavor of the mushrooms. This seasoning step is essential for fully maximizing the taste of your Cheesy Stuffed Portobello Mushrooms.

Step 4: Make Filling
In a mixing bowl, combine your cooked quinoa or rice with chopped spinach, diced tomatoes, mozzarella, and Parmesan cheese. Add minced garlic and dried oregano to the mix for an aromatic punch. Season the filling with salt and pepper to taste, ensuring a well-rounded flavor profile before you stuff the mushrooms with this cheesy, delicious mixture.

Step 5: Stuff Mushrooms
Carefully spoon the filling into each Portobello cap, packing it lightly to prevent overflow. As you fill each mushroom, make sure to let some of the filling mound on top, creating a hearty and satisfying look. This generous stuffing is what makes your Cheesy Stuffed Portobello Mushrooms a true delight for the senses.

Step 6: Bake
Once all the caps are filled, place them on the prepared baking sheet and slide them into the preheated oven. Bake for 20-25 minutes or until the mushrooms are tender and the cheese is melted and bubbly, with a light golden color. This baking step is crucial for developing the rich flavors in your Cheesy Stuffed Portobello Mushrooms.

Step 7: Garnish and Serve
After baking, allow the mushrooms to cool for a few minutes. This short cooling time helps to meld the flavors while preventing burns when you serve. Garnish your Cheesy Stuffed Portobello Mushrooms with freshly chopped parsley for a pop of color and added freshness before serving warm to your delighted guests.
