Red mullet in a vibrant Livorno-style tomato sauce with olives and capers. This high protein mediterranean family dinner is fresh, flavorful, and supports a healthy eating lifestyle.
Pat the red mullet fillets dry with paper towels and season both sides lightly with sea salt and black pepper.
In a large skillet, heat extra-virgin olive oil over medium heat. Add chopped onion and sauté for 4-5 minutes until softened, then add minced garlic and cook 1 minute until fragrant.
Pour in canned whole peeled tomatoes, gently crushing them with a spoon. Stir in kalamata olives, capers, and crushed red pepper flakes; simmer the sauce uncovered over medium-low heat for 10 minutes, allowing it to thicken.
Nestle the seasoned red mullet fillets into the simmering tomato sauce in a single layer. Spoon some sauce over each fillet and cover the skillet.
Cook over low heat for 8-10 minutes, carefully checking doneness by testing with a fork—the fish should flake easily but remain moist. Remove from heat, sprinkle with freshly chopped parsley, and serve immediately.
