Step-by-Step Instructions
- Prepare the Blackened Seasoning:
- Mix all dry spices in a bowl until they're evenly combined. A good mix means every bite tastes the same. Take a moment to break up any small lumps for the smoothest coating.
- Season the Salmon:
- First, dry the salmon completely - this matters for getting a good sear. Spread olive oil all over both sides with your fingers or a brush. Push the spice mix firmly onto all parts of the salmon. The oil helps spices stick and will make that amazing crust.
- Cook the Salmon:
- Get your pan hot until you see a bit of smoke. Put salmon in with skin down first - this guards the soft meat and makes the skin nice and crispy. You'll hear a nice sizzle when fish meets pan. Don't move it for 4 minutes, then flip it with a fish spatula. The difference between the spicy outer crust and tender inside is what makes this dish stand out.
- Make the Creamy Dijon Sauce:
- Stir all sauce stuff together until it's totally smooth. Try it and add more seasonings if needed - the sauce should be tangy and creamy with a little kick from the Dijon and garlic. The cool sauce goes perfectly with the hot spicy salmon.
- Serve:
- Put salmon on plates right after cooking and pour sauce generously over top, letting some run around the sides. The hot salmon will warm the sauce a bit, making it even more delicious.

The blackening way started in Louisiana Cajun cooking, where Chef Paul Prudhomme made it famous with redfish. I've changed it for salmon because the rich fatty meat handles the strong spices well, making a fancier dish that even folks who don't usually go for fish tend to like.
Perfect Pairings
Blackened salmon goes great with lighter sides that match its strong taste. Try serving it with a fresh arugula salad with lemon dressing or some steamed asparagus. For a bigger meal, wild rice mix or small roasted potatoes work really well. The creamy sauce also tastes fantastic drizzled over the veggie sides, bringing the whole meal together nicely.
Making Ahead and Storage
You can mix the blackened seasonings up to a month before and keep them in a sealed container. The Dijon sauce stays good in the fridge for up to 3 days too. For any leftover cooked salmon, store it in a sealed container away from the sauce and warm it gently in a 275°F oven just until it's heated through, about 10 minutes. Warming it slowly keeps the salmon from drying out so it stays juicy.
Customizing Your Heat Level
The best thing about making your own blackened mix is you can change how spicy it is. For a lighter version good for kids or people who don't like spice, use half the cayenne or skip it completely, adding more paprika instead. For those who love heat, double the cayenne or add a bit of habanero powder. Don't forget that the cool creamy sauce helps balance even the spiciest versions.

This dish mixes easy cooking with fancy results for a truly unforgettable meal. It'll be a hit whether you're feeding family or friends.
Frequently Asked Questions
- → How can I tell when my salmon is cooked just right?
Your salmon is done when it hits 145°F (63°C) inside. You'll notice it flakes apart easily with your fork but still looks juicy. The outside should be dark and crispy while the middle stays tender and light pink.
- → Can I make the blackened seasoning less spicy?
You bet! Just cut back on the cayenne pepper or leave it out completely for a milder taste. If you want it extra hot, toss in more cayenne or add some red pepper flakes.
- → Is it okay to make the sauce a day or two early?
For sure! You can mix up the Dijon sauce up to three days before and keep it in the fridge in a sealed container. This makes your dinner prep way faster when you're busy.
- → What foods go well on the side with this salmon?
This salmon tastes great with so many things! Try it with roasted asparagus, broccoli, or Brussels sprouts. It's also yummy on top of rice, quinoa, or next to some garlicky mashed potatoes. Want something lighter? Serve it with a fresh green salad.
- → Can I use salmon that's been frozen for this?
You can, but make sure to thaw it completely and pat it dry with paper towels before adding spices. Too much water will stop the spices from getting crispy and they'll steam instead of sear.
- → Do you have a non-dairy option for the sauce?
You can totally make this without dairy! Just grab some vegan mayo for the sauce base. Everything else stays the same, and it'll taste almost identical to the original.
