Blackened Salmon with Creamy Dijon Sauce
Tired of the same old boring weeknight dinners? I get it. You want something that tastes amazing but doesn’t require a million pots and pans or a culinary degree.
You’ve probably stood in the fish aisle, looked at a nice piece of salmon, and thought, “I’m just going to mess this up.” A lot of people feel that way. Fish can be tricky. It’s easy to overcook and even easier to under-season.
Well, this recipe is about to change all that. We’re making blackened salmon with a creamy dijon sauce that sounds fancy but is shockingly simple. This is the kind of meal that makes you look like a kitchen rockstar, even on a Tuesday.
What You’ll Need
Let’s get our ingredients lined up. Having everything ready to go is half the battle. This is what chefs call “mise en place,” which is just a fancy way of saying “get your stuff together.”
For the Blackened Salmon:
- Four 6-ounce salmon fillets, skin on or off is your choice
- 1 tablespoon olive oil
- 2 teaspoons smoked paprika
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon dried thyme
- 1/2 teaspoon cayenne pepper (or more if you like heat)
- 1/2 teaspoon black pepper
- 1 teaspoon salt
For the Creamy Dijon Sauce:
- 1 tablespoon unsalted butter
- 2 cloves garlic, minced
- 1/2 cup chicken or vegetable broth
- 1/2 cup heavy cream
- 2 tablespoons Dijon mustard
- 1 tablespoon fresh parsley, chopped
- Salt and pepper to taste
Pro Tips
I’ve cooked more salmon than I can count, and I’ve made all the mistakes so you don’t have to. Here are a few things that will make a huge difference.
- Get That Pan Hot: Don’t be shy. A medium-hot pan is key to getting that perfect blackened crust without overcooking the inside. If the oil isn’t shimmering slightly, wait another minute.
- Pat Your Salmon Dry: This is a big one. Use a paper towel to pat the salmon fillets completely dry before you season them. Moisture is the enemy of a good sear. A dry surface gets crispy; a wet one just steams.
- Don’t Crowd the Pan: Give each piece of salmon its own space in the skillet. If you cram them all in, they’ll steam instead of sear. Cook in two batches if your pan isn’t big enough.
- Trust the Process: Once you place the salmon in the pan, leave it alone. Don’t poke it or try to move it for at least 3-4 minutes. It will release from the pan easily when the crust is formed.
Tools for the Job
You don’t need any fancy gadgets for this. Just the basics will do.
- Large non-stick or cast-iron skillet
- Small bowl (for mixing spices)
- Whisk
- Measuring spoons
- Spatula (a fish spatula is great, but any will work)
- Cutting board and knife
Substitutions and Variations
Don’t have something on the list? No problem. Cooking is all about making things work for you. Here are some simple swaps.
| Ingredient | Substitution | Notes |
|---|---|---|
| Salmon | Cod, halibut, or even chicken breasts | Adjust cooking time. White fish and chicken cook differently. |
| Heavy Cream | Half-and-half, or full-fat coconut milk | Coconut milk will add a slightly sweet flavor. |
| Dijon Mustard | Stone-ground mustard or a spicy brown mustard | This will change the flavor profile of the sauce, but still be good. |
| Cayenne Pepper | A pinch of red pepper flakes or chipotle powder | Adjust the amount based on your spice preference. |
You can also add a squeeze of fresh lemon juice to the sauce at the end to brighten it up. Or toss some capers in there for a salty, briny kick.
Make-Ahead Tips
If you want to get a head start, you totally can.
- Spice Mix: The blackening spice blend can be made way ahead of time. Mix up a big batch and store it in an airtight container for months.
- Sauce Prep: You can mince your garlic and chop your parsley ahead of time. I wouldn’t make the full sauce ahead, as cream sauces are best when fresh.
How to Make It: Step-by-Step
Alright, let’s get cooking. Follow these steps and you’ll be golden.
Step 1: Prepare the Salmon
Pat your salmon fillets completely dry with a paper towel. This is super important for getting a good crust.
Step 2: Mix the Spices
In a small bowl, mix together the smoked paprika, garlic powder, onion powder, thyme, cayenne, black pepper, and salt.
Step 3: Season the Salmon
Sprinkle the spice mixture generously over the top of each salmon fillet. Gently press the spices into the fish to help them stick.
Step 4: Cook the Salmon
Heat the olive oil in a large skillet over medium-high heat. Once the oil is hot and shimmering, place the salmon fillets spice-side down. Cook for 4-5 minutes, without moving them, until a dark crust forms. Flip the salmon and cook for another 3-4 minutes, or until cooked to your liking. Remove the salmon from the pan and set it aside.
Step 5: Start the Sauce
Reduce the heat to medium. Add the butter to the same skillet. Once it’s melted, add the minced garlic and cook for about 30 seconds until you can smell it.
Step 6: Build the Sauce
Pour in the chicken broth, scraping up any browned bits from the bottom of the pan. This is where all the flavor is. Let it simmer for a minute.
Step 7: Finish the Sauce
Whisk in the heavy cream and Dijon mustard. Let the sauce bubble gently for 2-3 minutes to thicken up a bit. Stir in the chopped parsley and season with a little more salt and pepper if it needs it.
Step 8: Serve
You can either return the salmon to the pan to coat it in the sauce or just spoon the sauce over the fillets on the plate. Your call.
Nutrition, Pairings, and More
Let’s talk about how to round out this meal. You’ve got a great main course, now what?
Serving Suggestions
This dish is pretty flexible. It goes well with a lot of different sides.
| Side Dish | Why It Works |
|---|---|
| Roasted Asparagus | Simple, quick, and the flavors work perfectly. |
| Rice Pilaf | Great for soaking up any extra sauce. |
| Mashed Potatoes | A creamy, comforting side that balances the spice. |
| Simple Green Salad | A light and fresh option to keep the meal balanced. |
Dietary Adjustments
Need to tweak this for a specific diet? Easy.
- Low-Carb/Keto: This recipe is already very low-carb. Just serve it with a green vegetable like broccoli or asparagus instead of rice or potatoes.
- Dairy-Free: Swap the heavy cream for full-fat canned coconut milk and use a dairy-free butter substitute or more olive oil. The sauce will still be creamy and delicious.
Leftovers and Storage
If you have any leftovers, they’re great for lunch the next day.
Store the salmon and sauce in an airtight container in the fridge for up to 2 days. The sauce might thicken up when it’s cold.
To reheat, it’s best to do it gently in a skillet over low heat. You can also flake the cold salmon over a salad, which is one of my favorite ways to eat it. Avoid the microwave if you can; it can make fish rubbery.
Frequently Asked Questions
Here are some questions that pop up all the time.
Q1. Can I use frozen salmon?
Ans: Yes, absolutely. Just make sure it’s fully thawed before you start. You can thaw it in the fridge overnight. And remember to pat it very dry.
Q2. My smoke alarm went off! What did I do wrong?
Ans: Nothing! Blackening seasoning has a lot of spices that can create smoke at high heat. Turn on your exhaust fan or open a window. It just means you’re getting a great crust.
Q3. My sauce seems too thin. How can I fix it?
Ans: Just let it simmer for a few more minutes. The heat will help it reduce and thicken naturally. Don’t crank the heat up too high, or the cream might separate.
Q4. Can I bake the salmon instead of pan-searing?
Ans: You can, but you won’t get that classic “blackened” crust. If you want to bake it, cook it at 400°F (200°C) for about 12-15 minutes.
