    • Why? Cooking seafood in a skillet is fast and easy, but seafood requires careful heat management. Overcooking cod makes it flake apart too early, and overcooking shrimp turns it rubbery. Following the heat intensity cues below ensures silky sauce and perfectly cooked seafood every time.

Equipment Needed

  • 12-inch Heavy-Bottomed Skillet (Cast iron or high-sided stainless steel preferred)

  • Paper towels (Crucial for drying seafood to get a clean sear)

  • Tongs and Fish Spatula

  • Measuring cups and spoons

Ingredients

The Seafood

  • 1.25 lbs (approx. 560g) Fresh Cod Fillets, cut into 3–4 equal portions

  • 1/2 lb (approx. 225g) Jumbo Shrimp, peeled, deveined, tails on or off

  • 1 tbsp Olive Oil (for searing)

  • 1/2 tsp Sea Salt

  • 1/4 tsp Black Pepper

  • 1/2 tsp Smoked Paprika (adds subtle warmth and golden color)

The Creamy Garlic Butter Sauce

  • 3 tbsp Unsalted Butter

  • 6 cloves Fresh Garlic, finely minced (do not substitute with jarred garlic)

  • 1/2 cup Low-Sodium Chicken or Seafood Stock

  • 1 cup Heavy Cream (or double cream)

  • 1/2 cup Freshly Grated Parmesan Cheese (grate yourself so it melts smoothly)

  • 2 cups Fresh Baby Spinach

  • 1/2 cup Sun-Dried Tomatoes in oil, drained and sliced

  • 1 tbsp Fresh Lemon Juice (plus extra lemon wedges for serving)

  • 2 tbsp Fresh Italian Parsley, chopped

Step-by-Step Cooking Instructions

1.Prep and Dry the Seafood:5 mins | Prep.

Pat the cod fillets and shrimp completely dry using paper towels. Moisture is the enemy of a good sear. Season both sides of the cod and shrimp evenly with sea salt, black pepper, and smoked paprika. Set aside on a clean plate.

2.Sear the Cod:5 mins | Medium-High Heat.

Heat 1 tablespoon of olive oil in your 12-inch skillet over Medium-High heat until shimmering. Carefully add the cod fillets. Cook undisturbed for 3–4 minutes until a golden crust forms on the bottom. Carefully flip using a fish spatula and cook for 1 additional minute. Remove the cod and transfer to a side plate (it will finish cooking in the sauce later).

3.Quick-Sear the Shrimp:2 mins | Medium-High Heat.

In the same hot skillet, add the shrimp in a single layer. Sear for 1 minute per side until they just turn pink and opaque. Immediately transfer the shrimp to the plate with the cod.

4.Aromatics & Deglazing:2 mins | Medium Heat.

Reduce heat to Medium. Add the butter to the skillet. Once melted, add the minced garlic and sauté for 30–45 seconds until fragrant (do not let it brown). Pour in the chicken stock to deglaze the pan, scraping up any browned bits stuck to the bottom with a wooden spoon. Let the liquid simmer and reduce by half (about 1 minute).

5.Build the Cream Sauce:3 mins | Medium-Low Heat.

Reduce heat to Medium-Low. Pour in the heavy cream and bring to a gentle simmer. Stir in the grated parmesan cheese until fully melted and silky. Add the sun-dried tomatoes and baby spinach. Stir gently for 1 minute until the spinach wilts into the sauce. Stir in the fresh lemon juice.

6.Reintegrate & Finish:3 mins | Low Heat.

Turn heat down to Low. Nestled the seared cod fillets and shrimp back into the simmering sauce, pouring in any accumulated juices from the plate. Spoon the sauce generously over the top of the seafood. Simmer for 2–3 minutes until the cod easily flakes with a fork and reaches an internal temperature of 145°F (63°C).

 

Expert Chef Tips for Success

  1. Avoid Pre-Grated Cheese: Pre-shredded parmesan contains anti-caking agents (like cellulose) that cause pan sauces to turn grainy or greasy. Grate a block of Parmigiano-Reggiano fresh for a smooth, velvety finish.

  2. Control the Heat: Never let heavy cream come to a rapid, boiling roll after adding lemon juice, or the dairy may curdle. Keep the heat on low and stir constantly.

  3. Thickening the Sauce: If you prefer a thicker sauce, let it simmer for an extra 2 minutes before nestling the seafood back into the skillet.

Serving Suggestions

This skillet dish creates a rich, garlic-infused sauce that demands something to soak it up:

  • Low-Carb / Keto: Serve over roasted cauliflower rice, steamed zucchini noodles, or alongside grilled asparagus.

  • Classic Comfort: Serve over a bed of garlic butter linguine, fettuccine, or creamy parmesan risotto.

  • Rustic Style: Serve directly from the skillet with a thick slice of warm, crusty sourdough or French baguette.
