What Ingredients You’ll Need

Here’s what I love about this ingredient list: most of it is probably already in your pantry or fridge. I’ve also broken it down by what each part does in the recipe, so you get the why—not just the what.

Salmon fillets (4 fillets, about 6 oz / 170g each) — Fresh is best, but frozen works if you thaw it completely and pat dry. I always look for skin-on for extra crispiness, but skinless is fine too.
Blackening seasoning (2 tbsp) — This is the magic mix of smoked paprika, cayenne, garlic powder, onion powder, dried thyme, oregano, salt, and pepper. I make my own blend (recipe below), but store-bought works if you’re in a rush.
Olive oil (2 tbsp) — For coating the salmon before seasoning. I prefer extra virgin for flavor, but regular olive oil is just fine.
Butter (1 tbsp) — Adds richness when searing the salmon. I sometimes swap half for ghee when I want a nuttier flavor.
For the creamy Dijon sauce:

Mayonnaise (¼ cup / 60ml) — Full-fat gives the best texture and flavor.
Whole grain Dijon mustard (2 tbsp) — This is the star of the sauce. I’m picky and always reach for Maille or Grey Poupon.
Lemon juice (1 tbsp) — Freshly squeezed, no shortcuts here. Brightens everything up.
Garlic (1 small clove, minced) — Adds a subtle kick without overpowering.
Fresh dill (1 tbsp, chopped) — Optional but highly recommended. If you don’t have dill, parsley works too.
Salt and pepper — To taste. I usually start with a pinch and adjust after mixing.

Optional garnish: Lemon wedges and extra fresh herbs for that final pop of color and flavor.

Quick tip: I always have lemons and garlic on hand because they’re my go-to flavor boosters for seafood. Also, don’t skip the fresh herbs—they make the sauce feel fresh and bright.

Equipment Needed

You don’t need a fancy kitchen to nail this savory blackened salmon recipe. I’ve made it in apartments with tiny stoves and old pans, and it still turned out amazing.

Non-stick or cast iron skillet — Cast iron is my favorite here because it gets that perfect sear and holds heat well, but non-stick works if that’s what you have.
Mixing bowl — For whisking together the creamy Dijon sauce.
Measuring spoons and cups — Because this blackened salmon recipe is all about balance in the spice blend and sauce.
Spatula or fish turner — For flipping the salmon gently without breaking the crust.
Sharp knife — To trim the salmon if needed and slice lemon wedges for garnish.

Pro tip: If you don’t have a cast iron, crank your non-stick pan on medium-high and don’t overcrowd the salmon. You want that sizzle!

How to Make It: Step-by-Step

Alright, let’s get cooking. I’m walking you through this savory blackened salmon recipe with creamy Dijon sauce exactly how I do it, with all the little tricks I’ve picked up.

Prepare the blackening seasoning (5 minutes)
Mix smoked paprika (1 tbsp), cayenne pepper (½ tsp), garlic powder (1 tsp), onion powder (1 tsp), dried thyme (½ tsp), oregano (½ tsp), salt (1 tsp), and black pepper (½ tsp) in a small bowl. This blend is the backbone of that smoky, spicy crust.
Prep the salmon (5 minutes)
Pat the salmon fillets dry with paper towels—this helps the seasoning stick and get that nice crust. Rub each fillet with olive oil (about ½ tbsp each), then sprinkle the blackening seasoning evenly on all sides, pressing it in gently. Don’t be shy here; the seasoning is what makes this recipe sing.
Make the creamy Dijon sauce (5 minutes)
In a small bowl, whisk together mayonnaise, whole grain Dijon mustard, lemon juice, minced garlic, chopped fresh dill, salt, and pepper until smooth. Taste and adjust salt or lemon juice if needed. Set aside in the fridge to let the flavors meld.
Sear the salmon (10 minutes)
Heat your skillet over medium-high heat and add the butter. Once melted and bubbling, carefully place the salmon fillets skin-side down (if skin-on). You should hear a satisfying sizzle. Cook without moving for about 4 minutes until the edges turn opaque and the crust is dark and crisp.
Flip and finish cooking (4-6 minutes)
Flip the salmon gently with a spatula and cook for another 3-5 minutes, depending on thickness, until the salmon flakes easily with a fork but isn’t dry. If using skinless, cook on the first side for about 3-4 minutes before flipping. The internal temperature should reach around 125°F (51°C) for medium-rare.
Rest and serve (2 minutes)
Transfer the salmon to plates and let it rest for a couple of minutes. Spoon the creamy Dijon sauce over the top or serve it on the side. Garnish with lemon wedges and extra herbs if you’re feeling fancy.

Heads up: If your pan smokes a lot during searing, open a window or turn on your vent fan. The blackening spices love to create that smoky aroma (and sometimes a mini kitchen fog).

My Best Tips & Techniques

Okay, here’s where I share everything I’ve learned from making this blackened salmon recipe way more times than I can count.

Don’t skip drying the salmon — Moisture is the enemy of a good crust. Pat those fillets dry like your life depends on it.
Use fresh spices when you can — I learned that old paprika loses its punch, so if yours has been sitting around for a year, swap it out.
Control the heat — Medium-high is your friend here. Too hot and you’ll burn the spices before the salmon cooks through; too low and you won’t get that crust.
Make extra sauce — I always double the creamy Dijon sauce because it’s fantastic on everything from steamed veggies to sandwiches.
Don’t crowd the pan — Cook in batches if needed. Overcrowding traps steam and ruins the sear.
Rest the salmon — I know you want to eat it right away, but resting lets juices redistribute for a moist finish.

Funny story: The first time I tried blackening salmon, I panicked when my kitchen filled with smoke and the fire alarm nearly went off. Turns out, it’s just the spices doing their thing. Now I keep a window open and embrace the smoky vibe.

Ways to Mix It Up

Once you’ve nailed the basic savory blackened salmon recipe, here are some fun ways to shake things up without losing that easy dinner special vibe.

Spicy Mango Salsa: Top the salmon with a fresh mango salsa (diced mango, red onion, cilantro, lime juice, and jalapeño) instead of the creamy Dijon sauce for a sweet and spicy twist. My friends went nuts over this combo.
Herb Butter Swap: Replace butter with garlic herb butter when searing for an extra layer of flavor. Bonus points if you use compound butter you made yourself.
Use Different Mustards: Try swapping whole grain Dijon with spicy brown mustard or honey mustard in the sauce for a flavor twist. I’m partial to the tang of whole grain, but it’s fun to experiment.
Sheet Pan Style: Toss the blackened salmon and some seasoned veggies (like asparagus or bell peppers) on a sheet pan and roast at 400°F (205°C) for 12-15 minutes. Less fuss, same great taste.
Swap the Fish: This blackening technique works beautifully on other firm fish like cod, halibut, or mahi-mahi. Just adjust cooking time accordingly.

Dietary adaptations? Try using vegan mayo and coconut oil for the sauce and searing, and swap salmon for marinated tofu or tempeh for a plant-based take.

Serving Ideas & Storage

This blackened salmon recipe shines when served fresh, but here’s how I like to enjoy and store leftovers.

Serving suggestions: Serve over a bed of fluffy jasmine rice or quinoa for a filling meal. I also love it alongside roasted Brussels sprouts or a crisp green salad for lighter dinners.
Breakfast twist: Leftover salmon makes a killer protein-packed addition to scrambled eggs or avocado toast the next morning.
Storage tips: Wrap leftovers tightly and store in the fridge for up to 3 days. The creamy Dijon sauce keeps well separately—just stir it up before serving.
Reheating: I prefer gently warming salmon in a skillet over low heat to keep the crust crispy. Microwave works in a pinch but can soften the crust.
Freezing: You can freeze cooked salmon, but the texture changes slightly. If you freeze, thaw overnight in the fridge and reheat gently.

FAQs

Q: Can I use frozen salmon for this blackened salmon recipe?

A: Absolutely! Just make sure to thaw it fully in the fridge overnight and pat it very dry before seasoning. That dryness is key to getting that crispy blackened crust.

Q: What can I substitute for the creamy Dijon sauce?

A: If you’re not a mayo fan, Greek yogurt mixed with Dijon mustard and lemon juice makes a lighter alternative. It won’t be quite as rich, but still tangy and delicious.

A: Look for a crust that’s dark and crisp, and cook until the salmon flakes easily with a fork but still feels slightly firm. If you have a thermometer, 125°F (51°C) is ideal for medium-rare. Resting will finish the cooking.

Q: Can I make the blackening seasoning ahead of time?

A: Yes! I usually make a big batch and keep it in an airtight jar. It lasts for months and saves so much time when dinner rolls around.
