Instructions

  1. Step 1: Heat 4 tbsp olive oil in a large paella pan over medium heat. Add 1 finely chopped onion and 1 large diced red bell pepper, sautéing for 5 minutes until soft and translucent.
  2. Step 2: Stir in 4 minced garlic cloves and 1 large grated tomato, cooking for 3 minutes until the mixture thickens and becomes fragrant.
  3. Step 3: Add 300 g short-grain rice and the soaked 1/2 tsp saffron threads with 2 tbsp water, stirring for 2 minutes to toast the rice evenly.
  4. Step 4: Pour in 750 ml hot chicken broth, season with 1 1/2 tsp salt and 1/2 tsp black pepper, and bring to a simmer. Cook uncovered on low heat for 15 minutes without stirring.
  5. Step 5: Nestle 200 g mussels, 200 g peeled shrimp, and 150 g calamari rings into the rice. Sprinkle 100 g frozen peas over the top, cover loosely with foil, and cook for another 10 minutes until seafood is cooked through and rice is tender.
  6. Step 6: Remove from heat and let rest for 5 minutes before serving with lemon wedges.
