Authentic Grilled Spanish Stuffed Mushrooms with Iberian Ham

Introduction

Transport your guests to a bustling plaza in Madrid without leaving your backyard. There is something undeniably magical about Spanish tapas culture—it is less about the meal and more about the shared experience of small, flavorful bites enjoyed with good company. This recipe for Grilled Spanish Stuffed Mushrooms (Champiñones Rellenos) captures the very essence of that rustic elegance. By combining the earthy depth of cremini mushrooms with the salty, cured luxury of Jamon Iberico and the nutty bite of aged Manchego cheese, you create an umami bomb that is impossible to resist.

Preparing these on an Arteflame grill elevates the dish entirely. Unlike a traditional oven, the Arteflame’s flat carbon steel cooktop sears the mushrooms to golden perfection, locking in the juices while imparting a subtle, wood-fired aroma that mimics the authentic cooking methods of the Spanish countryside. Whether you are hosting a summer soirée or looking for a sophisticated appetizer to start your steak night, these stuffed mushrooms are a testament to the beauty of simple, high-quality ingredients coming together over an open fire.

Ingredients

• 24 large Cremini or Button mushrooms (cleaned and stems removed)
• 4 oz Iberian Ham (Jamon Iberico), finely diced
• 1 cup Manchego cheese, freshly grated
• 1/4 cup fresh parsley, finely chopped
• 3 cloves garlic, minced
• 3 tablespoons Extra Virgin Olive Oil
• 1 teaspoon smoked paprika (Pimentón de la Vera)
• Salt and freshly ground black pepper to taste
• Lemon wedges (for serving)

Instructions

Step 1: Prepare the Mushrooms

1. Clean the mushrooms gently using a damp cloth or paper towel to remove any dirt. Avoid soaking them in water to prevent them from becoming soggy.
2. Carefully pop out the stems from the mushroom caps. Set the caps aside on a baking sheet.
3. Finely chop the removed mushroom stems; do not discard them, as they will add earthiness to the filling.

Step 2: Create the Iberian Filling

1. In a medium mixing bowl, combine the chopped mushroom stems, diced Iberian ham, grated Manchego cheese, minced garlic, and chopped parsley.
2. Drizzle one tablespoon of olive oil into the mixture to bind it together.
3. Add the smoked paprika and a pinch of black pepper. Be sparing with salt, as the Iberian ham and Manchego are naturally salty. Mix thoroughly until the ingredients are evenly distributed.

Step 3: Stuff the Caps

1. Brush the outside of each mushroom cap generously with the remaining olive oil. This ensures a beautiful sear on the grill.
2. Using a small spoon, generously stuff each mushroom cap with the ham and cheese mixture. Press the filling down gently to ensure it stays compact during grilling.

Step 4: Grill on the Arteflame

1. Fire up your Arteflame grill. You are looking for a medium heat zone on the flat cooktop (plancha), usually found towards the middle-outer ring.
2. Lightly oil the cooktop surface. Place the mushrooms cap-side down (filling facing up) directly on the steel surface.
3. Grill for approximately 8 to 12 minutes. Watch for the cheese to melt and bubble, and the mushroom caps to soften and turn a golden brown.
4. Once the filling is golden and the mushrooms are tender, remove them from the grill and let them rest for 2 minutes before serving.

Tips

Mastering stuffed mushrooms on the grill requires just a few insider tricks to ensure they remain juicy rather than dry or soggy. First, the "Sponge Effect" is real; mushrooms absorb water rapidly. Never submerge them when cleaning; a simple wipe with a damp cloth ensures they sear rather than steam. Secondly, if you cannot source authentic Jamon Iberico, which can be a delicacy, high-quality Serrano ham or even Prosciutto di Parma makes for an excellent substitute, offering a similar cured saltiness profile.

Regarding the grilling process on the Arteflame, temperature management is key. You want to place the mushrooms on a part of the cooktop that sizzles but doesn't scorch. If the bottom of the mushroom cap is browning too quickly before the cheese melts, slide them further out toward the cool edge of the ring. To accelerate the melting of the Manchego without overcooking the bottom, you can briefly cover the mushrooms with a basting dome or a metal bowl for the last 60 seconds of cooking.

Variations

While the classic combination of ham and cheese is a staple, the versatile nature of mushrooms allows for endless creativity. You can easily adapt this recipe to suit different dietary preferences or flavor profiles without losing the Spanish soul of the dish. Here are a few ways to mix things up:

• The Vegetarian Tapas: Omit the ham and replace it with finely diced sun-dried tomatoes and roasted red peppers for a savory, meat-free burst of flavor.
• The Spicy Matador: Add finely diced Spanish Chorizo instead of Iberian ham and mix in a pinch of cayenne pepper for a smoky heat.
• The Blue Note: Swap the Manchego for Cabrales (a Spanish blue cheese) and top with a crushed walnut for a bold, tangy variation.
• The Herb Garden: Use goat cheese instead of Manchego and increase the amount of fresh herbs, adding thyme and rosemary for a lighter, fresher taste.
• The Seafood Twist: Replace the ham with chopped shrimp or crab meat and add a zest of lemon to the filling mixture.

Best pairings

To truly honor the Spanish origins of this dish, your drink and side pairings should complement the rich, salty, and earthy flavors of the stuffed mushrooms. These bite-sized appetizers are bold, so they need accompaniments that can stand up to the umami intensity of the Iberian ham and aged cheese. Serving these as part of a larger tapas spread is the traditional and most enjoyable way to eat them.

• Wine: A medium-bodied Rioja (Tempranillo) is the classic choice, as its tannins cut through the fat of the cheese and ham. Alternatively, a crisp, dry Albariño offers a refreshing contrast to the savory mushroom.
• Cocktails: A traditional Red Sangria filled with citrus fruit, or a Rebujito (sherry and lemon-lime soda) for a lighter summer vibe.
• Side Dishes: Pair with Patatas Bravas (spicy potatoes), blistered Padrón peppers, or a simple bowl of marinated olives to complete the tapas experience.
