Authentic Portuguese Pork Belly with Mustard Glaze Recipe

Transport your taste buds to the sun-drenched Iberian coast with this mouthwatering recipe for Portuguese Pork Belly with Mustard Glaze. Unlike standard barbecue pork, this dish relies on the harmonious balance between rich, rendered fat and a sharp, tangy finish that cuts right through the heaviness. Cooking this on an Arteflame grill elevates the experience entirely; the flat-top plancha provides the perfect surface to achieve an edge-to-edge sear that locks in moisture while creating that coveted, crackling crust.

The secret lies in the simplicity of the ingredients and the high-heat capability of the grill. As the pork belly sizzles on the carbon steel cooktop, the fat renders out, frying the meat in its own juices before being slathered in a savory mustard concoction. Whether you are hosting a summer backyard feast or looking for a hearty winter comfort meal, this Portuguese-inspired dish delivers bold, rustic flavors that are indistinguishable from a meal served in a Lisbon tavern.

Ingredients

The Meat & Marinade

• 2 lbs Pork Belly, sliced into thick strips (approx. 1 inch thick)
• 1 cup Dry White Wine (Vinho Verde is authentic, but Pinot Grigio works)
• 4 cloves Garlic, crushed or minced
• 2 Bay Leaves, broken
• 1 tbsp Coarse Sea Salt
• 1 tsp Freshly Ground Black Pepper
• 1 tbsp Smoked Paprika (optional for extra depth)

The Mustard Glaze

• 1/2 cup Yellow Mustard (or Dijon for a sharper, more refined flavor)
• 2 tbsp Unsalted Butter, melted
• 1 tbsp Olive Oil
• 1 tsp Hot Sauce (Piri-Piri sauce recommended for authenticity)
• 1 tbsp Lemon Juice
• Fresh Parsley, chopped (for garnish)

Instructions

Step 1: Marinate the Pork

1. In a large bowl or resealable bag, combine the white wine, minced garlic, broken bay leaves, paprika, salt, and pepper.
2. Add the pork belly strips, ensuring they are fully submerged or coated in the mixture.
3. Refrigerate for at least 2 hours, though letting it sit overnight yields the most tender and flavorful results.

Step 2: Prepare the Arteflame Grill

1. Start a fire in the center of your Arteflame grill using wood or charcoal.
2. Allow the grill to burn down until the center cooktop reaches searing temperature (over 400°F). The outer edges will be cooler, perfect for slow roasting if needed.
3. Lightly oil the plancha surface with a paper towel dipped in vegetable oil to ensure a non-stick surface.

Step 3: Sear the Pork Belly

1. Remove the pork from the marinade and pat it dry with paper towels. This is crucial for getting a crispy crust rather than steaming the meat.
2. Place the pork belly strips directly onto the hot flat-top grill griddle.
3. Sear for 4-5 minutes on each side. You want a deep golden-brown crust to form. The fat should render and bubble, crisping the edges.
4. Move the pork to a slightly cooler zone on the grill if the outside is browning too fast before the inside is cooked through.

Step 4: Apply the Mustard Glaze

1. While the pork is finishing, whisk together the mustard, melted butter, olive oil, lemon juice, and hot sauce in a small heat-safe bowl.
2. Using a basting brush, generously coat both sides of the pork belly strips with the glaze while they are still on the grill.
3. Let the glaze caramelize slightly for 1-2 minutes, turning once to ensure it sticks to the meat without burning.

Step 5: Rest and Serve

1. Remove the pork belly from the grill and transfer it to a cutting board.
2. Let the meat rest for 3 to 5 minutes to allow the juices to redistribute.
3. Garnish with fresh chopped parsley and serve immediately while hot and crispy.

Tips

To master this Portuguese Pork Belly recipe, heat management on the Arteflame is your best friend. The center of the cooktop is the hottest, which is perfect for the initial sear, but pork belly is a fatty cut that can cause flare-ups if cooked solely over an open flame. Utilize the flat-top surface to render the fat safely and evenly. If your pork belly strips are particularly thick, start them on the medium-heat zone to cook the interior before moving them closer to the center for that final crispy finish.

Additionally, do not skip the drying step after removing the meat from the marinade. Moisture is the enemy of the Maillard reaction (browning). If the meat is wet, it will steam rather than sear, leaving you with a chewy texture instead of a crispy one. For an extra pop of flavor, brush a little bit of the glaze onto the grill surface right before placing the meat down for the final turn—this infuses the smoke with mustard aromatics.

Variations

This recipe is highly adaptable depending on your palate or dietary preferences. While the mustard base is traditional for this specific dish, you can easily tweak the flavor profile to suit different themes. Here are a few ways to mix it up:

• Sweet & Savory: Add 2 tablespoons of honey or maple syrup to the mustard glaze to counteract the acidity and assist in caramelization.
• Herb-Crusted: Mix fresh rosemary and thyme into the marinade and sprinkle dried oregano over the pork while grilling for a Mediterranean twist.
• Spicy Piri-Piri: Double the amount of Piri-Piri sauce and add red pepper flakes to the glaze for a fiery version that mimics authentic Portuguese street food.
• Citrus Burst: Substitute the white wine marinade with a mixture of orange juice and lime juice for a brighter, zestier flavor profile.
• Garlic Lover’s: Roast whole garlic cloves on the plancha alongside the pork and mash them into the glaze before applying.

Best pairings

Portuguese pork belly is rich and savory, requiring sides and drinks that can cut through the fat and cleanse the palate. In Portugal, this dish is often served with simple, rustic accompaniments that don't compete with the main star. A fresh, crisp salad or a starch that can soak up the flavorful juices is ideal.

• Sides: Serve with "Batatas a Murro" (punched potatoes) roasted on the grill, or a simple tomato and onion salad with vinaigrette. Grilled asparagus or charred peppers also complement the smokiness well.
• Wine: A chilled glass of Vinho Verde is the classic pairing; its slight effervescence and high acidity balance the fatty pork perfectly. Alternatively, a medium-bodied red like a Douro blend works well.
• Beer: A crisp, cold lager (like Super Bock or Sagres) is a refreshing choice for outdoor grilling.

Conclusion

Grilling Portuguese Pork Belly with a mustard glaze on the Arteflame is more than just cooking dinner; it is an exploration of texture and bold flavors.
