Ingredients

Instructions

  1. Step 1: In a small bowl, steep 1/4 tsp saffron threads in 2 cups hot water for 10 minutes to release color and aroma.
  2. Step 2: Pour the saffron water into a large skillet and bring to a gentle simmer over medium heat. Season 4 cod fillets with 1/2 tsp salt and 1/4 tsp black pepper, then gently add them to the simmering broth. Poach for 8-10 minutes, turning once halfway, until the fish is opaque and flakes easily.
  3. Step 3: While the cod poaches, heat 3 tbsp olive oil in a blender or food processor. Add 3 minced garlic cloves and sauté in the oil over medium heat in a small pan until fragrant, about 1 minute, then transfer to the blender.
  4. Step 4: Add 2 roasted red peppers, 1/4 cup toasted almonds, 1 tsp smoked paprika, 1 tbsp sherry vinegar, and 1/2 tsp salt to the blender. Pulse until smooth but slightly textured, scraping down sides as needed.
  5. Step 5: Remove the cod from the broth with a slotted spatula and plate. Spoon the Romesco sauce generously over the fillets and serve with lemon wedges for squeezing.

Total time is about 30 minutes (15 min prep + 15 min cook). A small batch typically covers several meals in the week — store as the recipe directs.

How do I store leftover Saffron-Poached Cod with Romesco Sauce?

Transfer to an airtight jar and refrigerate for up to 5–7 days. Most sauces freeze well for up to 2 months — portion into small containers or freezer bags so you can thaw only what you need. Stir before serving; cream- or yogurt-based sauces may separate on standing.

Can I substitute ingredients in Saffron-Poached Cod with Romesco Sauce?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Saffron-Poached Cod with Romesco Sauce for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.

What goes well with Saffron-Poached Cod with Romesco Sauce?

Spanish seafood like this pair well with a simple grain (rice, couscous, or crusty bread), a quick salad with acid (lemon vinaigrette, pickled onions), and a pan sauce or yogurt-based dip. Tap "Plan a meal with the AI" to get specific side suggestions.
