This blackened salmon is seasoned with a homemade Cajun spice blend and broiled for only eight minutes. It delivers bold flavor with minimal effort—an ideal weeknight dinner that pairs well with grains, salads, or simple roasted vegetables.
Delicious Blackened Salmon
Blackened salmon gets its name from the dark, charred crust that forms when a garlic- and paprika-forward Cajun-style rub is exposed to high heat. In this version, fillets are rubbed generously with a mild homemade Cajun seasoning and placed under the broiler until the rub chars slightly and develops a smoky, peppery crust.
This technique is fast and forgiving: in about 8 minutes your salmon will be cooked through and beautifully flavored. Serve it over rice, quinoa, or a bed of greens, or flake the leftovers into salads, wraps, or grain bowls for easy meals throughout the week.
Why you’ll love it

Featured Ingredients
- Salmon fillets: Skin-on fillets work best here. Choose fillets that are similar in size so they cook evenly under the broiler.
- Cajun seasoning: A homemade blend keeps heat balanced and fresh. If you prefer more spice, increase the cayenne or crushed red pepper. If you prefer milder flavor, reduce the cayenne or add a teaspoon of brown sugar to temper the heat.
- Lemon slices: A squeeze of fresh lemon brightens the finished fish and balances the spice.
Quick Tip!
Salmon Internal Temperature
Salmon is best when the internal temperature reaches about 125ºF to 130ºF and the flesh appears light pink and opaque. Use an instant-read thermometer for accuracy.
Simple Instructions
1. Dry the fillets. Line a baking sheet with parchment and place the salmon skin-side down. Pat each fillet with a paper towel to remove excess moisture—this helps the rub form a crust.
2. Season the salmon. Sprinkle about 1 tablespoon of Cajun seasoning over each fillet and press the spice into the fish so it adheres. Drizzle the fillets lightly with olive oil or avocado oil.
3. Broil the salmon. Position the oven rack near the top so the fillets sit just under the broiler element. Broil for approximately 8 minutes, watching closely; the rub should darken and form a crust. Start checking around 5 minutes to avoid overcooking.
4. Rest and serve. Remove the salmon from the oven and let it rest for 5 to 15 minutes to let the juices redistribute. Serve with fresh lemon slices and your favorite sides.

Top Tips
- Dry the salmon thoroughly before applying the rub to promote a crisp, darkened crust.
- Place the oven rack close to the broiler so the fillets char properly in a short time.
- Rest the fish briefly after broiling so the juices redistribute—this keeps the fillets moist.
- If the rub is too spicy for your taste, serve with a cooling sauce such as a creamy herb dressing or yogurt-based dip.
FAQ
Blackened fish is coated with a spice blend that chars and darkens when cooked at high heat, creating a richly flavored crust.
Blackened salmon is a nutritious choice—rich in protein and omega-3 fatty acids, and a good source of potassium and other nutrients when prepared with moderate amounts of oil and salt.
When broiling in the oven, you do not need to flip blackened salmon. Cooking it skin-side down under high heat yields the desired crust and cooks the fillet through evenly.
Try Surrender Salmon!
One popular choice among home cooks is Surrender Salmon, a brand known for wild-caught Alaska salmon. Many find the flavor bright and the texture flaky—perfect for recipes like this.
If you have access to a reputable local or wild-caught salmon source, it’s a great way to enjoy fresh, flavorful fillets.
Storage
Allow the salmon to cool completely, then transfer to an airtight container. Store in the refrigerator for up to 4–5 days. Reheat gently or enjoy cold in salads and sandwiches.
