From selecting the freshest scallops to mastering the perfect sear, this guide will equip you with everything you need to create a simple yet impressive dish that’s sure to impress family and guests alike.

Preparing the Scallops for Cooking

Before searing scallops in a cast iron skillet, it’s essential to prepare them properly to achieve the best texture and flavor. Start by ensuring your scallops are thoroughly dried. Excess moisture will prevent a good sear and can cause steaming instead. Use paper towels to pat each scallop dry gently but thoroughly.

Next, remove the small side muscle, sometimes called the “foot,” if it has not already been removed. This piece can be tough and chewy when cooked. Simply pull it off with your fingers—it should come away easily.

Seasoning the scallops is straightforward but crucial. Lightly sprinkle both sides with salt and freshly ground black pepper. The seasoning enhances the natural sweetness of the scallops without overpowering their delicate flavor. Some chefs also recommend a light dusting of flour or cornstarch to enhance the crust formation, but this is optional depending on your desired texture.

Heating and Preparing the Cast Iron Skillet

The cast iron skillet must be preheated properly for a perfect sear. Place the skillet on the stove over medium-high heat and allow it to become very hot. This may take 5 to 7 minutes, depending on your stove and skillet thickness. A properly heated pan ensures the scallops will caramelize quickly without sticking.

To test if the pan is hot enough, sprinkle a few drops of water onto the skillet. The water should sizzle and evaporate immediately. If it just sits or evaporates slowly, allow more time for heating.

Use a high smoke point oil such as grapeseed, avocado, or refined olive oil. Add about one to two tablespoons of oil to the skillet, swirling to coat the bottom evenly. Avoid butter at this stage, as it burns easily at high heat and can impart a bitter flavor.

Searing the Scallops

Once the pan is hot and the oil shimmering, add the scallops in a single layer, leaving space between each to avoid overcrowding. Overcrowding causes scallops to steam instead of sear, preventing a golden crust.

Allow the scallops to cook undisturbed for approximately 1.5 to 2 minutes, depending on their size. The edges will turn opaque, and a golden crust will form on the bottom. Avoid moving or flipping them prematurely, as this will disrupt the crust formation.

After the first side is seared, use tongs or a spatula to carefully flip each scallop. Cook for another 1 to 2 minutes on the opposite side. The scallops should be firm but still slightly translucent in the center to avoid overcooking, which leads to a rubbery texture.

Finishing Touches and Serving

Once cooked, remove the scallops immediately from the skillet to prevent carryover cooking. For added flavor, you may briefly add a pat of butter, minced garlic, and fresh herbs such as thyme or parsley to the hot skillet after removing the scallops. Swirl the melted butter and aromatics, then drizzle over the scallops.

Serve the scallops promptly while hot, paired with complementary sides such as a light salad, risotto, or sautéed vegetables.

Recommended Cooking Times and Temperatures

Scallop Size Cooking Time per Side Internal Temperature Visual Indicator
Small (10-15 count/lb) 1.5 minutes 125°F (52°C) Opaque edges, slightly translucent center
Medium (8-10 count/lb) 2 minutes 130°F (54°C) Firm texture, golden crust
Large (6-8 count/lb) 2.5 minutes 130-135°F (54-57°C) Firm but tender, lightly translucent center

Additional Tips for Perfect Scallops

  • Avoid overcrowding: Cook scallops in batches if necessary to maintain high skillet temperature.
  • Use fresh scallops: Freshness ensures sweetness and texture; thaw frozen scallops completely before cooking.
  • Do not add scallops before pan is hot: Adding scallops too soon causes sticking and poor sear.
  • Rest briefly after cooking: Let scallops rest for a minute off heat to redistribute juices.
  • Experiment with flavors: Finish with lemon zest, chili flakes, or a splash of white wine for added complexity.

Preparing and Selecting Scallops for Cast Iron Cooking

Before searing scallops in a cast iron skillet, it is crucial to select the right type and prepare them properly to achieve a perfect golden crust and tender interior.

Choosing Scallops:

  • Type: Opt for dry-packed scallops rather than wet-packed. Dry-packed scallops have not been treated with phosphates or water, resulting in a superior sear and flavor.
  • Size: Sea scallops typically range from 10-20 per pound. Larger scallops tend to cook more evenly and are easier to handle in a skillet.
  • Freshness: Look for scallops that are firm to the touch, slightly translucent, and have a clean, ocean-fresh aroma without any fishy smell.

Preparation Steps:

  • Thawing: If frozen, thaw scallops overnight in the refrigerator or under cold running water, then pat dry immediately.
  • Removing the Side Muscle: Peel off the small, rectangular side muscle (also called the “foot”) if still attached, as it can be tough and chewy.
  • Drying: Thoroughly pat the scallops dry with paper towels. Excess moisture inhibits proper browning.
  • Seasoning: Lightly season both sides with salt and freshly ground black pepper just before cooking to avoid drawing out moisture prematurely.

Essential Cast Iron Pan Setup and Heating Techniques

A properly preheated cast iron skillet is critical to achieving the signature caramelized crust on scallops without overcooking their delicate interiors.

Preheating the Pan:

  • Place the cast iron skillet over medium-high heat and allow it to warm for 3-5 minutes.
  • To test readiness, sprinkle a few drops of water on the pan; if they evaporate instantly with a slight sizzle, the pan is sufficiently hot.

Oil Selection and Application:

  • Use a high smoke point oil such as grapeseed, avocado, or refined canola oil.
  • Add approximately 1-2 tablespoons to the pan, swirling to coat evenly.
  • Heat the oil until it shimmers but does not smoke.

Temperature Control:

  • Maintain medium-high heat throughout cooking.
  • If the pan starts to smoke excessively, reduce the heat slightly to avoid burning the oil or scallops.
