1 tablespoon chopped fresh parsley
Paprika, to coat
12 large mushrooms

1 1/2 cups Japanese-style bread crumbs

Large Mixing Bowls
Baking Tray
Sauté Pan
Cutting Board

Instructions

Begin by preparing the mushrooms. Gently remove the stems from all 12 large mushrooms and place the caps in a large mixing bowl. Save the stems! We’ll use them later.
Drizzle 1 ounce of extra virgin olive oil over the mushroom caps. Season generously with salt and pepper to taste. Ensure the caps are evenly coated.
Arrange the seasoned mushroom caps on a baking tray with the gills facing upwards. This allows the mushrooms to release their moisture during the roasting process.
Roast the mushrooms in a preheated oven at 350°F (175°C) for 15 minutes. This will partially cook the mushrooms and soften them for stuffing.
Remove the baking tray from the oven and let the mushrooms cool slightly. Once they are cool enough to handle, carefully flip them over to allow any accumulated juice to drain. Discard the juice.
Now, let’s prepare the spinach filling. In a sauté pan, heat the remaining 1 ounce of olive oil over medium heat. Add the minced garlic and sauté until it becomes fragrant and slightly golden, but not burnt. This usually takes about 30 seconds to 1 minute.
Add the 6 cups of fresh spinach to the pan. Season with salt and pepper to taste.
Stir the spinach continuously until it wilts and reduces in volume. This process usually takes a few minutes. Once the spinach is cooked, remove the pan from the heat, drain any excess liquid, and allow the spinach to cool.
Once cooled, transfer the spinach to a cutting board and lightly chop it. This helps to distribute the spinach evenly within the filling.
Let’s create the buttery topping. In a large mixing bowl, combine the 1/2 pound (8 ounces) of softened butter, salt, pepper, oregano, granulated garlic, basil, parsley, and the Japanese bread crumbs.
Mix all the ingredients together by hand until they are roughly combined. The mixture should resemble a coarse crumble.
Form the butter mixture into 1-ounce discs. These discs will be placed on top of the stuffed mushrooms for a delicious, buttery gratin.
In a separate mixing bowl, combine the cooked and chopped spinach with the grated Fontina cheese. Mix well to ensure the cheese is evenly distributed throughout the spinach.
Now, it’s time to stuff the mushrooms. Fill each mushroom cap with 1 to 2 ounces of the spinach and Fontina cheese mixture. Gently pack the filling into the mushroom caps.
Top each stuffed mushroom with one of the 1-ounce butter mixture discs.
Sprinkle the stuffed mushrooms generously with paprika. This adds a touch of color and a subtle smoky flavor.
At this point, you can either keep the stuffed mushrooms refrigerated until you are ready to bake them, or you can bake them immediately.
To bake, preheat your oven to 350°F (175°C). Bake the stuffed mushrooms until they are golden brown and the filling is heated through, about 15-20 minutes.
Garnish with fresh lemon wedges and serve immediately.

Expert Tips & Tricks

Mushroom stem savings: Don’t toss the mushroom stems! Finely chop them and sauté them with the garlic before adding the spinach for added flavor and texture in the filling.
Cheese Choices: While Fontina is traditional, feel free to experiment with other cheeses. Gorgonzola or a blend of Parmesan and Mozzarella can also work beautifully.
Make-Ahead Magic: Assemble the stuffed mushrooms ahead of time and store them in the refrigerator. This is perfect for entertaining. Just remember to add a few minutes to the baking time if baking from cold.
Preventing Soggy Mushrooms: Make sure to thoroughly drain the cooked spinach to prevent soggy stuffed mushrooms. You can even squeeze the spinach with paper towels to remove excess moisture.
Toasting Breadcrumbs: For an extra layer of flavor, lightly toast the Japanese bread crumbs in a dry skillet over medium heat before adding them to the butter mixture. This will enhance their nutty flavor and add a bit more crunch.

Serving & Storage Suggestions

Serve Maggiano’s Stuffed Mushrooms immediately while they are hot and the cheese is melted and bubbly. Garnish with a lemon wedge for a burst of freshness. These are perfect as an appetizer or side dish.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, bake in a preheated oven at 350°F (175°C) until heated through, about 10-15 minutes. You can also reheat them in a microwave, but the butter topping may not be as crisp.

FAQs (Frequently Asked Questions)

Q: Can I use pre-shredded Fontina cheese?
A: While you can, freshly grated Fontina melts more evenly and has a better flavor. Pre-shredded cheese often contains cellulose to prevent clumping, which can affect its melting properties.

Q: Can I freeze the stuffed mushrooms?
A: Yes, you can freeze the stuffed mushrooms before baking. Place them on a baking sheet and freeze until solid, then transfer them to a freezer-safe bag. Bake from frozen, adding about 10-15 minutes to the baking time.

Q: My mushrooms released a lot of liquid while baking. Is that normal?
A: Yes, it’s normal for mushrooms to release liquid. Be sure to drain the cooked mushrooms well before stuffing them to prevent a soggy final product.

Q: How can I prevent the butter topping from burning?
A: If the butter topping starts to brown too quickly, cover the mushrooms loosely with foil for the remaining baking time.

Q: Can I use dried herbs instead of fresh?
A: Yes, you can substitute dried herbs for fresh herbs. Use about 1 teaspoon of dried herbs for every tablespoon of fresh herbs.
