Langoustines in a spicy tomato-wine sauce from Trieste in Friuli Venezia Giulia. This high protein mediterranean dish is fresh, bold, and a festive family dinner from Italy's northeast coast.
Heat 3 tbsp olive oil in a wide pan over medium heat. Add chopped onion and sauté gently for 5 minutes until translucent, stirring frequently.
Add minced garlic and red chili flakes; sauté for 1 minute, just until aromatic, maintaining medium heat to avoid burning.
Stir in the crushed tomatoes and cook, uncovered, for 10 minutes, allowing the sauce to reduce slightly. Add white wine and simmer for 2 more minutes to let the alcohol evaporate.
Add the langoustines in a single layer, shell-on, into the simmering sauce. Sprinkle with salt and pepper. Cover and cook over medium-high heat for 5-7 minutes, turning once halfway, until the langoustines turn opaque and are just cooked through.
Uncover, sprinkle with fresh parsley, and simmer for 2 more minutes on medium heat to combine flavors and slightly thicken the sauce. Serve immediately with pan juices spooned over each portion.
