This Portuguese-style grilled chicken has been a warm-weather obsession in my family for years. I first learned this method during a summer barbecue when a friend brought a butter-forward piri-piri sauce that transformed ordinary grilled bird into something unbelievably tender and flavourful. The combination of bright citrus, smoked paprika and a touch of store-bought piri piri yields a slightly spicy glaze that crisps up beautifully on a hot grill while keeping the meat juicy and tender. Every time I make it, the scent of garlic and paprika brings neighbours to the backyard and gets everyone talking.

I discovered a few practical tricks that make a huge difference: spatchcocking the chicken for even cooking, rubbing coarse salt with a halved lemon to season and lightly tenderize the flesh, and using a two-zone grill so the skin crisps without burning. The sauce is cooked slowly on the stove until slightly thickened, balanced with white wine and a touch of butter that gives richness without overpowering the chili notes. When guests take their first bite and close their eyes, you know you’ve done it right.

Ingredients

• Shallots: 2 medium shallots, thinly sliced. Look for firm, dry-skinned shallots; they brown quickly and add a sweet onion base to the sauce without sharpness.
• Olive oil: 1/2 cup extra-virgin olive oil. Choose a fruit-forward bottle you enjoy drinking — it shows through in the sauce.
• Piri piri sauce: 2 tablespoons prepared piri piri. A mild to medium heat works well; adjust to taste. I like Nando's or a local artisan brand.
• Sweet paprika: 2 tablespoons. Use Spanish smoked paprika if you prefer a smokier profile; sweet paprika keeps the colour vivid.
• White wine: 1/2 cup dry white wine. Sauvignon blanc or a dry unoaked wine works well to deglaze and brighten the sauce.
• Chicken broth: 1/2 cup low-sodium broth; if you have a good boxed broth such as RICARDO Chicken Broth, it adds depth without extra salt.
• Unsalted butter: 1/2 cup (1 stick) softened. The butter rounds the edge of the heat and yields a glossy finish when used to baste.
• Garlic: 2 cloves, chopped. Fresh, pungent garlic gives that classic Portuguese kick.
• Whole chicken: about 4 lb (1.8 kg). Fresh or fully thawed is best; spatchcock for even cooking.
• Coarse salt: 4 teaspoons. Use kosher or sea salt for even seasoning and texture.
• Lemon: 1/2 lemon. Rubbing the cut lemon with the salt helps dissolve and distribute seasoning while imparting bright acidity.

Instructions

Make the spicy sauce: In a small saucepan over high heat, warm 1/4 cup of the olive oil and add the thinly sliced shallots. Let them brown lightly to develop sweetness, about 3 minutes, watching closely so they don’t burn. Stir in the piri piri and paprika and cook for 1 minute to bloom the spices. Add the remaining 1/4 cup oil, the white wine and chicken broth, bring to a simmer and reduce for roughly 12 to 15 minutes until the liquid thickens slightly. Remove from heat, stir in the softened butter and chopped garlic, cook for another minute off the heat so garlic mellows, then set aside to cool slightly. Spatchcock the bird: Place the chicken breast-side down on a cutting board. Using kitchen shears or a sharp chef’s knife, cut along both sides of the backbone and remove it. Flip the chicken and press firmly on the breastbone to flatten; you should hear the breast crack slightly. This allows the chicken to lie flat and cook evenly over indirect heat. Season and marinate: Season the interior and exterior generously with the coarse salt. Rub the cut side of the lemon over the flesh and skin for about 3 minutes; the citrus helps dissolve the salt and lightly tenderizes. Let rest 5 minutes, then place the bird in a large glass dish and coat with 1/4 cup of the prepared spicy sauce. Cover tightly with plastic wrap. Transfer the remaining sauce to an airtight container and refrigerate both chicken and reserved sauce for at least 12 hours or overnight for best flavour penetration. Prepare the grill: Preheat one side of the grill to high and leave the other side unlit to create two zones (direct and indirect heat). Oil the grate with a folded paper towel dipped in oil and held with tongs to prevent sticking. Grill low and slow: Drain excess marinade, place the flattened chicken skin-side down on the unheated (indirect) side of the grill. Close the lid and cook for 45 minutes, maintaining an internal ambient grill temperature around 350°F if possible. This gentle approach cooks the thighs through without charring the skin. Flip and finish: Flip the chicken and continue cooking another 30 minutes or until a digital thermometer in the thickest part of the thigh reads 180°F. For crisp skin, move the bird to the heated section briefly, watching carefully, to render and brown the skin without burning. Warm the reserved sauce and baste: While the chicken rests, warm the reserved sauce in a small saucepan over medium-low heat until glossy and slightly thickened. Brush the cooked pieces generously with the warm sauce immediately before serving.

Storage Tips

Store cooled leftovers in airtight containers in the refrigerator for up to 3 days. To freeze, wrap portions tightly in plastic wrap, then aluminum foil, or use vacuum-sealed bags for best quality; freeze up to 3 months. Reheat gently in a 350°F oven, covered for 10 to 15 minutes, then uncover and brush with reserved sauce to refresh the glaze and crisp the skin under a preheated broiler for a minute or two if needed. For sandwiches, thinly slice cold chicken and toast the bread lightly for contrast.

Ingredient Substitutions

If you don’t have prepared piri piri, substitute with 2 teaspoons crushed red pepper or a blend of hot sauce plus a pinch of smoked paprika for depth. Swap the white wine for an equal amount of extra chicken broth plus 1 teaspoon lemon juice if avoiding alcohol. To reduce butter, use 2 tablespoons instead of 1/2 cup and finish with a drizzle of high-quality olive oil for shine. For lower sodium, use low-sodium broth and taste before adding extra salt.

Serving Suggestions

Serve with grilled lemon halves, a simple green salad, roasted baby potatoes or garlic rice. Garnish with chopped parsley and extra lemon wedges. For a Portuguese-inspired platter, add crusty bread, sautéed collard greens or a tomato and cucumber salad dressed with olive oil and vinegar. This bird shines with chilled white wine or a crisp rosé.

Cultural Background

Portuguese grilled chicken, often associated with piri-piri peppers, has roots in the Portuguese colonies of Africa where fiery chiles were integrated into local cooking. The British and Portuguese popularized the style, and restaurants around the world adapted it. The hallmark is a bright, pepper-forward sauce often enriched with garlic and buttery or oily elements to create balance between heat and richness.

Seasonal Adaptations

In summer, grill alongside skewered vegetables and serve with citrusy salads. In cooler months, roast the spatchcocked bird in a hot oven at 425°F and finish under the broiler to crisp the skin. Swap fresh herbs depending on season — oregano and thyme in fall, parsley and lemon zest in spring — to keep the profile bright year-round.

Meal Prep Tips

Spatchcock and marinate the bird up to 24 hours ahead to save time on cooking day. Reserve sauce separately and warm it just before serving. If preparing for lunches, carve and portion into airtight containers and include a small container of reserved sauce to brush when reheating for optimal moistness.

Finish by carving the chicken into pieces and brushing generously with the reserved warm sauce. Serve immediately and enjoy the applause. This approach makes a delightful centrepiece for casual dinners or festive gatherings — feel free to adapt heat levels and sides to your crowd and make it your signature summer grilled chicken.
