Baked Salmon Cajun Spices

The first time I made Cajun salmon, my entire apartment smelled like a French Quarter kitchen. My neighbor actually knocked on my door to ask what I was cooking. That spicy, aromatic warmth has made this my go-to when I need dinner to feel like an occasion without any real effort.

I served this at a small dinner party last winter when everyone was exhausted from work. My friend Sarah who claims to hate fish went back for seconds. Now she asks for the recipe every time she comes over.

Ingredients

• Salmon fillets: Six ounce portions cook evenly and stay moist, skin-on gives you that crispy edge if you want it
• Cajun seasoning: The backbone of the dish, homemade lets you control the heat level
• Paprika: Smoked adds depth but sweet works if that is what you have
• Garlic and onion powder: These savory notes balance the heat and round out the flavor
• Dried thyme and oregano: Earthy herbs that keep the seasoning blend grounded
• Cayenne pepper: Optional depending on your spice tolerance, but I say go for it
• Olive oil: Helps the spices adhere and keeps the fish from drying out
• Lemon: Bright acid cuts through the rich spices and complements the salmon
• Fresh parsley: Adds a pop of color and fresh finish to the final dish

Instructions

Get your oven ready:

Preheat to 400°F and line a baking sheet with parchment paper for the easiest cleanup ever

Prep the salmon:

Pat those fillets completely dry with paper towels and place them skin side down on the sheet

Mix your spices:

Combine Cajun seasoning, paprika, garlic powder, onion powder, thyme, oregano, and cayenne in a small bowl

Oil and season:

Drizzle olive oil over each fillet and rub it in gently, then sprinkle that spice blend evenly over every piece

Add the finishing touches:

Place a lemon slice on top of each fillet and pop everything in the oven

Bake to perfection:

Let it cook 12 to 15 minutes until the fish flakes easily with a fork

Serve it up:

Scatter fresh parsley over the hot salmon and bring it to the table while it is still steaming

Save

This recipe became my weeknight savior during a particularly hectic month. Salmon felt fancy enough for Tuesday but simple enough that I did not resent making it after work.

Getting That Crispy Top

Sometimes I switch on the broiler for the last minute or two of baking. The spices toast and caramelize just a bit, creating this incredible crust that contrasts beautifully with the tender fish underneath. Watch it like a hawk because the high sugar content in some spice blends can go from perfect to burned in seconds.

Making It Your Own

I have discovered that Creole seasoning works beautifully if you want slightly less heat. My husband prefers it when I dial back the cayenne and add a touch more brown sugar to the spice mix for a sweet and spicy situation that he cannot stop talking about.

Serving Ideas That Actually Work

Roasted vegetables with a little char from the oven complement the smoky spices so well. Simple lemon rice picks up on the citrus notes from the salmon. A crisp green salad with a tangy vinaigrette cuts through the richness of the fish.

• Leftovers flake perfectly into scrambled eggs the next morning
• Cold salmon works over mixed greens for an instant lunch
• The spice blend keeps for months in a dark cupboard

Save

Some nights the best meals are the ones that come together almost effortlessly but still make you feel like you actually cooked something. This salmon is exactly that.
