Seared salmon is a weeknight dinner champion. It’s quick, healthy, and incredibly delicious when cooked right. And there’s no better tool for achieving that perfect sear than a cast iron skillet. This recipe guides you through creating restaurant-quality, cast-iron skillet seared salmon with crispy skin and a moist, flaky interior. Get ready to impress yourself and your family with this simple yet elegant dish.

## Why Cast Iron for Salmon?

Cast iron skillets are renowned for their superior heat retention and even heating. This is crucial for searing salmon because:

* **Even Cooking:** Ensures the entire salmon fillet cooks at a consistent temperature, preventing hot spots that can lead to uneven cooking.
* **High Heat Searing:** Cast iron can withstand extremely high temperatures, allowing you to achieve a beautiful, crispy skin without overcooking the flesh.
* **Heat Retention:** Maintains a consistent temperature throughout the cooking process, even when you add the salmon to the pan. This helps create that perfect sear.

## Ingredients for Cast Iron Skillet Salmon

Here’s what you’ll need to create this masterpiece:

* **Salmon Fillets:** 2 (6-8 ounce) salmon fillets, skin on or off (see notes below).
* **Oil:** 1-2 tablespoons of high-heat oil (such as avocado oil, grapeseed oil, or refined coconut oil).
* **Salt:** Kosher salt or sea salt, to taste.
* **Black Pepper:** Freshly ground black pepper, to taste.
* **Optional Seasonings:** Garlic powder, onion powder, paprika, dried herbs (such as thyme or rosemary), lemon pepper, or your favorite fish seasoning blend.
* **Lemon Wedges:** For serving.
* **Optional Sauce:** A simple pan sauce (recipe below) or your favorite sauce for salmon.

**A Note on Skin On vs. Skin Off:**

* **Skin On:** If you want that crispy, irresistible salmon skin, opt for skin-on fillets. The skin provides a barrier that helps protect the flesh from drying out during searing. Scoring the skin lightly can help prevent it from curling up during cooking.
* **Skin Off:** If you prefer a less crispy, more tender texture, skin-off fillets work perfectly well. Just be mindful not to overcook them.

## Equipment

* **Cast Iron Skillet:** A 10-inch or 12-inch cast iron skillet is ideal.
* **Tongs or Spatula:** For flipping the salmon fillets.
* **Paper Towels:** For patting the salmon dry.
* **Instant-Read Thermometer:** To ensure the salmon is cooked to the correct internal temperature.

## Step-by-Step Instructions

Follow these detailed instructions for perfect cast iron skillet salmon every time:

### Step 1: Prepare the Salmon

1. **Pat Dry:** This is the most crucial step for achieving crispy skin. Use paper towels to thoroughly pat the salmon fillets dry on both sides. Removing excess moisture allows the skin to crisp up properly in the hot pan.
2. **Season Generously:** Season the salmon fillets generously with salt and pepper on both sides. Don’t be afraid to be liberal with the seasoning, as some of it will be lost during the searing process. If using additional seasonings (garlic powder, onion powder, etc.), apply them evenly as well.

### Step 2: Heat the Cast Iron Skillet

1. **Preheat:** Place the cast iron skillet over medium-high heat. Allow the skillet to heat up completely. This usually takes 5-7 minutes. The skillet is ready when a drop of water flicked into the pan sizzles and evaporates almost immediately.
2. **Add Oil:** Once the skillet is hot, add the oil. Let the oil heat up for a few seconds until it shimmers. This ensures the salmon doesn’t stick to the pan.

### Step 3: Sear the Salmon

1. **Place Salmon in Skillet:** If using skin-on fillets, place the salmon fillets skin-side down in the hot skillet. If using skin-off fillets, place them in the skillet flesh-side down.
2. **Sear:** Sear the salmon for 4-6 minutes per side, depending on the thickness of the fillets. Do not move the salmon around during the searing process. Allow it to develop a beautiful golden-brown crust.
3. **Flip and Cook:** Carefully flip the salmon fillets with tongs or a spatula. Continue cooking for another 2-4 minutes, or until the salmon is cooked through.

### Step 4: Check for Doneness

1. **Internal Temperature:** The best way to determine if the salmon is cooked through is to use an instant-read thermometer. Insert the thermometer into the thickest part of the fillet. The internal temperature should reach 145°F (63°C).
2. **Visual Cues:** The salmon is done when it flakes easily with a fork and the flesh is opaque throughout. Avoid overcooking the salmon, as it will become dry.

### Step 5: Rest and Serve

1. **Rest:** Remove the salmon from the skillet and place it on a plate. Let it rest for a few minutes before serving. This allows the juices to redistribute, resulting in a more tender and flavorful fillet.
2. **Serve:** Serve the salmon immediately with lemon wedges and your favorite sides. Consider a simple green salad, roasted vegetables, rice, or quinoa.

## Tips for Perfect Cast Iron Skillet Salmon

* **Use High-Quality Salmon:** The quality of your salmon will significantly impact the final result. Opt for fresh, sustainably sourced salmon whenever possible.
* **Don’t Overcrowd the Pan:** If you’re cooking more than two salmon fillets, cook them in batches to avoid overcrowding the pan. Overcrowding can lower the temperature of the pan and prevent the salmon from searing properly.
* **Avoid Moving the Salmon Too Much:** Resist the urge to move the salmon around while it’s searing. Allowing it to sit undisturbed in the hot pan is crucial for developing a crispy crust.
* **Adjust Cooking Time Based on Thickness:** Thicker fillets will require a longer cooking time. Use an instant-read thermometer to ensure the salmon is cooked to the correct internal temperature.
* **Don’t Overcook:** Overcooked salmon is dry and unpleasant. Err on the side of slightly undercooked, as the salmon will continue to cook slightly as it rests.
* **Use a Well-Seasoned Cast Iron Skillet:** A well-seasoned cast iron skillet is naturally non-stick, making it easier to sear the salmon without it sticking to the pan.
* **Clean Your Cast Iron Skillet Properly:** After cooking, clean your cast iron skillet according to the manufacturer’s instructions. Avoid using soap, as it can strip the seasoning.

## Pan Sauce for Cast Iron Skillet Salmon (Optional)

Elevate your cast iron skillet salmon with a simple pan sauce. This sauce is made with the flavorful fond (browned bits) left in the skillet after cooking the salmon.

**Ingredients:**

* 1 tablespoon butter
* 1 shallot, minced
* 1/4 cup dry white wine (such as Sauvignon Blanc or Pinot Grigio)
* 1/4 cup chicken broth
* 1 tablespoon lemon juice
* 1 tablespoon chopped fresh parsley (optional)
* Salt and pepper to taste

**Instructions:**

1. **Melt Butter:** After removing the salmon from the skillet, melt the butter over medium heat.
2. **Sauté Shallot:** Add the minced shallot and sauté until softened and translucent, about 2-3 minutes.
3. **Deglaze Pan:** Pour in the white wine and scrape up any browned bits from the bottom of the skillet. Let the wine reduce by half, about 2-3 minutes.
4. **Add Broth and Lemon Juice:** Add the chicken broth and lemon juice. Bring to a simmer and cook for another 2-3 minutes, or until the sauce has slightly thickened.
5. **Season and Finish:** Season the sauce with salt and pepper to taste. Stir in the chopped fresh parsley (if using).
6. **Serve:** Pour the pan sauce over the seared salmon and serve immediately.

## Serving Suggestions

Cast iron skillet salmon is incredibly versatile and pairs well with a variety of sides. Here are a few suggestions:

* **Roasted Vegetables:** Asparagus, broccoli, Brussels sprouts, carrots, or bell peppers are all excellent choices.
* **Green Salad:** A simple green salad with a vinaigrette dressing provides a refreshing contrast to the richness of the salmon.
* **Rice or Quinoa:** These grains are a healthy and filling accompaniment to salmon.
* **Mashed Potatoes or Sweet Potatoes:** Creamy mashed potatoes or sweet potatoes are a classic pairing with salmon.
* **Lemon Wedges:** A squeeze of fresh lemon juice brightens the flavor of the salmon.
* **Garlic Bread:** Crispy garlic bread is perfect for soaking up any leftover pan sauce.

## Variations

* **Spice it up:** Add a pinch of red pepper flakes to the salmon before searing for a touch of heat.
* **Herb Crusted:** Before searing, press chopped fresh herbs (such as dill, parsley, or chives) onto the salmon fillets.
* **Maple Glazed:** Brush the salmon with a maple glaze during the last few minutes of cooking for a sweet and savory flavor.
* **Citrus Marinade:** Marinate the salmon in a citrus-based marinade (such as lemon, lime, or orange juice) for 30 minutes before searing.
* **Blackened Salmon:** Use a blackened seasoning blend for a bold and flavorful crust.

## Storage and Reheating

* **Storage:** Leftover cooked salmon can be stored in an airtight container in the refrigerator for up to 3 days.
* **Reheating:** Reheat the salmon gently in a skillet over low heat or in the microwave. Avoid overcooking, as it can become dry.
