Instructions

  1. Step 1: Preheat a grill pan or cast iron skillet over medium-high heat. Toss 1 lb trimmed asparagus with 1 tbsp olive oil, 1/2 tsp sea salt, and 1/4 tsp black pepper. Grill asparagus for 6-8 minutes, turning occasionally, until charred and tender. Set aside.
  2. Step 2: In a food processor, combine 1 cup roasted red peppers, 1/3 cup toasted almonds, 2 minced garlic cloves, 1 tbsp sherry vinegar, 1 tsp smoked paprika, 1/4 tsp dried chili flakes, and 1 torn slice stale bread. Pulse until coarsely blended, then slowly add 1 tbsp olive oil while processing to create a thick sauce. Season with 1/4 tsp sea salt and black pepper to taste.
  3. Step 3: Pat dry 4 cod fillets and season both sides with 1/2 tsp sea salt and 1/4 tsp black pepper. Heat 1 tbsp olive oil in a large non-stick skillet over medium-high heat. Add cod and cook for 4 minutes on the first side until golden and crispy.
  4. Step 4: Carefully flip the cod and cook for another 3 minutes until opaque and flaky. Remove from heat.
  5. Step 5: Plate the cod fillets topped with 1/2 cup Romesco sauce each and serve alongside the charred asparagus.

How do I store leftover Pan-Seared Cod with Romesco Sauce and Charred Asparagus?

How do I scale Pan-Seared Cod with Romesco Sauce and Charred Asparagus for a different number of people?
