Instructions

Step 1: Preheat oven to 300°F. In a small bowl, combine 3 tbsp olive oil, 6 minced garlic cloves, 1 tbsp red chili flakes, 2 tsp smoked paprika, 2 tbsp lemon juice, 2 tbsp red wine vinegar, 2 tsp salt, 1 tsp black pepper, and 1 tbsp chopped fresh oregano to create the piri-piri marinade.
Step 2: Rub the entire 3 lbs pork shoulder evenly with the marinade mixture, making sure to coat all sides well. Place the pork in a roasting pan and pour 1/2 cup water into the bottom to keep it moist.
Step 3: Cover the roasting pan tightly with foil and slow roast the pork shoulder in the oven for 4 to 5 hours, or until the meat is fork-tender and easily pulls apart.
Step 4: Remove the foil and increase oven temperature to 425°F. Roast uncovered for an additional 20 minutes to develop a crispy outer crust.
Step 5: Let the pork rest for 15 minutes before slicing or pulling apart to serve with pan juices and extra piri-piri sauce on the side.
