• Fat: 22g

Ingredients

• 4 (6oz) Salmon Fillets, skin-on or off

• 2 tbsp Melted Butter (or Avocado Oil for high heat)

• 3 tbsp Cajun Seasoning (look for a low-sodium blend)

• 1/2 tsp Smoked Paprika

• Fresh lemon wedges and parsley for garnish

For the Homemade Remoulade:

• 1/2 cup Mayonnaise

• 1 tbsp Creole Mustard (or stone-ground mustard)

• 1 tbsp Prepared Horseradish

• 1 tsp Cajun Seasoning

• 1 tsp Pickle Juice (the secret ingredient!)

• 1/2 tsp Dried Dill or fresh chopped parsley

Instructions

1. Prep the Sauce: In a small bowl, whisk together all remoulade ingredients. Cover and chill in the fridge while you prepare the fish. (This allows the flavors to meld).

2. Season the Salmon: Pat the salmon fillets completely dry with a paper towel. Brush both sides with melted butter or oil. Sprinkle the Cajun seasoning and smoked paprika generously over the tops, pressing it in slightly to form a thick "crust."

3. The Sear: Heat a heavy cast-iron skillet over medium-high heat until it just begins to smoke.

4. Blacken: Place the salmon fillets in the hot skillet, seasoned side down. Sear for 3-4 minutes undisturbed until a dark, fragrant crust forms.

5. Flip and Finish: Carefully flip the fillets and cook for another 3-5 minutes, depending on the thickness, until the salmon flakes easily with a fork.

6. Plate and Serve: Spoon a generous dollop of remoulade over each fillet and serve with plenty of fresh lemon wedges.

Tips & Variations

• The Cast Iron Advantage: For an authentic blackened finish, a cast-iron skillet is a must. It holds the high, even heat necessary to char the spices without burning the butter.

• The "Holy Trinity" Side: Serve this over a bed of sautéed onions, celery, and green bell peppers for a full Cajun experience.

• Control the Heat: If you want a "swicy" twist, drizzle a teaspoon of honey over the salmon just after it comes out of the skillet.

• Vessel Tip: If cooking indoors, ensure your kitchen is well-ventilated! Blackening involves high heat and spices, which can create a bit of smoke—that’s how you know you’re doing it right.

Make-Ahead & Storage

• Remoulade: The sauce can be made up to 5 days in advance and kept in the fridge.

• Salmon: Blackened salmon is best enjoyed fresh. However, leftovers can be stored in an airtight container for up to 2 days.

• Reheating: Reheat gently in a pan over medium-low heat with a splash of water and a lid to keep it from drying out.

FAQ

Is blackened salmon burnt? Not at all! The "black" color comes from spices and butter caramelizing at high heat, creating a flavorful crust. The fish inside remains tender and flaky.

Can I bake this instead? Yes! You can bake the seasoned fillets at 400°F for 12-15 minutes. You won't get the same deep char as the skillet method, but it will still be delicious.

Final Thoughts

This Blackened Salmon with Remoulade is a true "Cozy Home" showstopper. It’s proof that you don’t need hours in the kitchen to create an authoritative, flavorful meal. Pair it with a side of Cajun Maque Choux and some warm cornbread for the perfect weeknight feast!
