this Recipe

Ingredients:

• For the Portobello Mushrooms:
  • 6 large Portobello mushroom caps (about 4-5 inches in diameter)
  • 2 tablespoons olive oil, plus more for drizzling
  • ½ teaspoon salt
  • ¼ teaspoon freshly ground black pepper
• For the Spinach and Cheese Filling:
  • 1 tablespoon olive oil
  • ½ medium yellow onion, finely diced
  • 3 cloves garlic, minced
  • 10 ounces frozen chopped spinach, thawed and very well-drained (or 1 lb fresh spinach, wilted and very well-drained)
  • 15 ounces ricotta cheese, whole milk preferred for creaminess
  • ½ cup shredded mozzarella cheese, plus an additional ¼ cup for topping
  • ¼ cup grated Parmesan cheese, plus an additional 2 tablespoons for topping
  • ¼ cup fresh parsley, finely chopped
  • 1 teaspoon dried oregano
  • ½ teaspoon red pepper flakes (optional, for a little heat)
  • ¼ teaspoon ground nutmeg (enhances spinach flavor beautifully)
  • ½ teaspoon salt, or to taste
  • ¼ teaspoon freshly ground black pepper, or to taste
• Optional Topping:
  • ¼ cup panko breadcrumbs
  • 1 tablespoon melted butter or olive oil (for tossing with breadcrumbs)

Preparing the Portobello Mushrooms

1. Preheat Your Oven: First things first, let’s get that oven ready! Preheat your oven to 400°F (200°C). While it’s heating up, grab a large baking sheet and line it with parchment paper for easy cleanup. This little step makes a big difference when you’re done cooking.
2. Clean the Mushroom Caps: Now, for our star ingredient, the beautiful Portobello mushrooms. You want to handle these gently. Using a damp paper towel or a soft brush, gently wipe any dirt or debris off the mushroom caps. Avoid rinsing them directly under water, as mushrooms are like little sponges and will absorb too much moisture, which can make them watery when baked. We want them tender, not soggy!
3. Remove the Stems and Scrape the Gills: Carefully twist off the stems from each mushroom cap. You can save these stems if you like, they’re great finely chopped and added to soups or stir-fries, but we won’t be using them in this recipe. Next, using a spoon, gently scrape out the dark gills from the underside of each mushroom cap. This is an important step for a couple of reasons: it removes the dark, earthy-tasting gills that can release excess moisture and turn your filling a muddy color, and it creates more space for our delicious spinach and cheese filling. You’ll notice a lot of dark material coming out – that’s perfectly normal! Be gentle so you don’t break the mushroom caps.
4. Season and Prepare for Baking: Once the gills are removed, you’ll have a nice, clean cavity. Place the cleaned mushroom caps, gill-side up, on your prepared baking sheet. Drizzle the insides and edges of each mushroom cap with about 2 tablespoons of olive oil, using your fingers or a brush to spread it evenly. Then, sprinkle them generously with ½ teaspoon of salt and ¼ teaspoon of black pepper. This seasoning step is key to building flavor from the ground up!
5. Pre-Bake the Mushrooms (Optional, but Recommended for Best Results): To ensure your Portobello mushrooms are perfectly tender and not too watery once stuffed, I highly recommend a quick pre-bake. Place the seasoned mushroom caps in the preheated oven for 10-15 minutes, gill-side up. This helps to release some of their natural moisture before we add the filling. You might see a small pool of liquid in the caps; simply drain this off before proceeding. This step makes a huge difference in the final texture of your “Spinach And Cheese Stuffed Portobello Mushrooms.”

Crafting the Spinach and Cheese Filling

6. Prepare the Spinach: If you’re using frozen spinach, ensure it’s completely thawed. Now, this next step is critical: you must squeeze out as much water as humanly possible from the spinach. I usually place the thawed spinach in a clean kitchen towel or several layers of paper towels and twist and squeeze over the sink until no more liquid comes out. Alternatively, you can use a fine-mesh sieve and press down with the back of a spoon. Excess water in the spinach will lead to a watery, bland filling, and we definitely don’t want that! If using fresh spinach, quickly wilt it in a pan with a tiny bit of olive oil, let it cool, and then squeeze out all the excess moisture using the same method.
7. Sauté the Aromatics: Heat 1 tablespoon of olive oil in a medium skillet over medium heat. Add the finely diced ½ yellow onion and cook, stirring occasionally, until it’s softened and translucent, about 5-7 minutes. You don’t want it to brown, just to become sweet and fragrant. Then, add the minced garlic and cook for another minute until it’s aromatic. Be careful not to burn the garlic, as it can turn bitter very quickly.
8. Combine the Filling Ingredients: In a large mixing bowl, combine the ricotta cheese, ½ cup shredded mozzarella, ¼ cup grated Parmesan, the well-drained spinach, and the sautéed onion and garlic mixture.
9. Season the Filling: Now, let’s infuse this filling with incredible flavor! Add the finely chopped fresh parsley, dried oregano, red pepper flakes (if using, for that lovely kick), and the ¼ teaspoon of ground nutmeg. The nutmeg is a secret ingredient here; it really enhances the flavor of the spinach without being overtly noticeable. Season with ½ teaspoon of salt and ¼ teaspoon of freshly ground black pepper.
10. Mix Thoroughly and Taste: Using a sturdy spoon or your hands (which I find works best for really incorporating everything), mix all the filling ingredients until they are thoroughly combined. This is your moment to taste and adjust! Spoon a small amount onto a clean spoon, taste it, and decide if it needs more salt, pepper, or maybe a little more spice from the red pepper flakes. Don’t be shy; getting the seasoning just right here makes all the difference in your “Spinach And Cheese Stuffed Portobello Mushrooms.”

Stuffing and Baking the Mushrooms

11. Fill the Portobello Caps: Once your pre-baked mushrooms have cooled slightly and any excess liquid has been drained, it’s time to stuff them. Spoon a generous amount of the spinach and cheese filling into each mushroom cap, mounding it nicely. Don’t be afraid to really pile it on; these mushrooms are hearty and can hold a lot! Gently press the filling down to ensure it’s compact.
12. Add the Topping (Optional, but Recommended for Texture): If you’re using the optional panko breadcrumb topping, combine the ¼ cup panko breadcrumbs with 1 tablespoon of melted butter or olive oil in a small bowl. Toss them gently to coat. This step adds a wonderful, crispy texture to the top of your stuffed mushrooms. Sprinkle a generous amount of this mixture over the top of the filling in each mushroom cap. If you’re skipping the breadcrumbs, simply sprinkle the remaining ¼ cup of shredded mozzarella and 2 tablespoons of grated Parmesan cheese over the tops of the filled mushrooms. A final drizzle of olive oil over the cheese will help it melt beautifully and brown.
13. Bake to Golden Perfection: Place the baking sheet with your generously stuffed Portobello mushrooms back into the preheated 400°F (200°C) oven. Bake for 20-25 minutes, or until the mushrooms are tender, the filling is heated through and bubbly, and the cheese on top (or breadcrumbs) is melted and golden brown. Keep an eye on them towards the end of the baking time to prevent any burning, especially if you have a powerful oven.
14. Rest Before Serving: Once they’re beautifully golden and bubbling, carefully remove the baking sheet from the oven. Let the “Spinach And Cheese Stuffed Portobello Mushrooms” rest for 5-10 minutes before serving. This short rest allows the filling to set slightly and prevents you from burning your mouth on the hot cheese!

Serving Suggestions and Pro Tips

Making Your Spinach And Cheese Stuffed Portobello Mushrooms Shine

• Serving: These incredible “Spinach And Cheese Stuffed Portobello Mushrooms” are wonderfully versatile. They make a fantastic vegetarian main course, especially when served alongside a crisp green salad or some crusty garlic bread. They can also be a delightful side dish to grilled chicken or fish, or even a sophisticated appetizer for a dinner party. For an appetizer, you might consider using smaller cremini mushrooms and adjusting baking time.
• Flavor Variations: Don’t be afraid to get creative with your filling!
  • Add More Veggies: Finely diced bell peppers, sun-dried tomatoes (pat them dry!), or even some chopped artichoke hearts can be added to the filling for extra flavor and texture. Sauté them along with the onion and garlic.
  • Spice It Up: If you love heat, a pinch more red pepper flakes or a dash of your favorite hot sauce can be mixed into the ricotta mixture.
  • Different Cheeses: While ricotta, mozzarella, and Parmesan are a classic trio, feel free to experiment. Goat cheese adds a tangy creaminess, feta provides a salty bite, and smoked provolone can lend a lovely depth of flavor.
  • Protein Boost: For a non-vegetarian option, you can mix in some cooked, crumbled Italian sausage, crispy bacon bits, or finely diced cooked chicken into the filling. Just make sure they are fully cooked before adding.
• Make-Ahead Tips: These stuffed mushrooms are excellent for meal prep or entertaining! You can prepare the spinach and cheese filling up to 2 days in advance and store it in an airtight container in the refrigerator. You can also clean and pre-bake the mushroom caps a day ahead. When you’re ready to cook, simply assemble the mushrooms, add the topping, and bake as directed. This makes entertaining a breeze!
• Reheating: Leftover “Spinach And Cheese Stuffed Portobello Mushrooms” reheat beautifully. Place them on a baking sheet and warm them in a preheated oven at 350°F (175°C) for about 10-15 minutes, or until heated through and the cheese is bubbly again. Microwaving is an option, but the texture won’t be as good, especially for the mushroom cap itself or any crispy topping.
• Troubleshooting Common Issues:
  • Watery Filling: This is almost always due to not squeezing enough moisture out of the spinach. Remember, that step is crucial!
  • Dry Mushrooms: If your mushrooms turn out dry, they might have been over-baked or cooked at too high a temperature for too long. The pre-bake should be just enough to release moisture, not cook them completely.
  • Bland Flavor: Did you remember to taste the filling before stuffing? Seasoning in layers (mushrooms, then filling) is essential. Don’t be shy with salt, pepper, and herbs!
