How to Make Blackened Salmon with Creamy Dijon Sauce Recipe
Step 1: Prepare the Blackening Spice Blend
Start by combining paprika, garlic powder, onion powder, thyme, oregano, cayenne pepper, salt, and black pepper in a small bowl. This spice mix is where the bold blackened flavor begins. Give your salmon fillets a gentle pat dry with paper towels so the seasoning sticks perfectly, then rub the blend evenly all over each fillet, coating every side with those gorgeous aromatics.
Step 2: Sear the Salmon
Heat a tablespoon of olive oil in a large skillet over medium-high heat until it’s shimmering. Place the salmon fillets skin-side down (if skin-on) and cook without moving for 3 to 4 minutes. This allows a beautiful crust to form. Carefully flip and cook the other side for an additional 3 to 4 minutes or until the salmon is cooked through but still tender and juicy on the inside. Remove from the pan and set aside to rest.
Step 3: Whip Up the Creamy Dijon Sauce
Lower the heat to medium-low in the same skillet and add a teaspoon of olive oil or butter. Pour in the heavy cream along with Dijon mustard, whole grain mustard if you’re using it, and lemon juice. Stir constantly as the sauce simmers gently for 2 to 3 minutes — it will thicken slightly, becoming smooth and luxurious. Season with salt and pepper to taste for that perfect balance of flavor.
Step 4: Bring It All Together
Plate your beautifully blackened salmon fillets and generously spoon the creamy Dijon sauce over the top. The rich sauce clings to the spicy crust in the most delightful way, making every bite melt in your mouth. Serve immediately while everything is warm, fresh, and inviting.

Garnishes
Simple garnishes can elevate both the presentation and the flavor. Freshly chopped parsley or chives add a pop of color and a fresh herbaceous bite that cuts through the richness of the sauce. Thin lemon wedges on the side offer a zesty, aromatic contrast that brightens every forkful.
Side Dishes
This dish partners beautifully with a range of sides. Roasted vegetables like asparagus, green beans, or Brussels sprouts bring texture and earthiness. Creamy mashed potatoes or fluffy rice soak up the leftover sauce marvelously. For a lighter take, a crisp green salad with a citrus vinaigrette is a refreshing complement.
Creative Ways to Present
For a special touch, try plating the salmon on a bed of herbed quinoa or wild rice, drizzle extra sauce artistically around the plate, and scatter microgreens on top. Serving it family-style on a wooden board with assorted grilled veggies invites a warm, communal dining experience that’s both elegant and approachable.
Make Ahead and Storage
Storing Leftovers
Any leftover salmon and sauce can be stored in an airtight container in the refrigerator for up to 2 days. Keep the sauce separate if you want to avoid the fish getting soggy, making reheating more effective.
Freezing
While salmon is best enjoyed fresh, you can freeze cooked blackened fillets wrapped tightly in plastic wrap and foil for up to 1 month. Creamy Dijon sauce doesn’t freeze as well due to the dairy content but can be frozen separately if done carefully, though texture changes are possible.
Reheating
Reheat salmon gently in a low oven (about 275°F) covered with foil to prevent drying out, or briefly in a skillet over low heat. Warm the sauce slowly in a small saucepan, whisking constantly to maintain creaminess without curdling.
FAQs
Can I use other types of fish for this recipe?
Absolutely! While salmon is ideal for its fatty texture and flavor, you can try blackened seasoning on cod, halibut, or even trout. Just keep in mind cooking times may vary due to thickness and moisture content.
Is the cayenne pepper necessary?
Not at all. The cayenne adds a pleasant heat, but if you prefer a milder dish, you can simply leave it out without losing the wonderful smoky blackened flavor.
Can I make the creamy Dijon sauce dairy-free?
Yes! Substitute the heavy cream with full-fat coconut milk or a plant-based cream alternative. The sauce will still be creamy and flavorful but with a slightly different profile.
How do I know when the salmon is perfectly cooked?
Look for the salmon to flake easily when gently pressed with a fork but still maintain a juicy, slightly translucent center. Overcooking can dry the fish, so aim for just opaque edges and a tender middle.
Can I grill the salmon instead of cooking it on the stovetop?
Definitely! Grilling is a fantastic option that adds additional smoky depth. Just be sure to oil the grill grates well and cook the salmon over medium heat to get that classic blackened crust without burning.
