One of the easiest ways to prepare salmon is rubbing it with this flavorful spice mix and cooking it on the grill. These spices create a deliciously crispy crust on the outside and moist, juicy fish on the inside. Super healthy, paleo, keto, dairy free and gluten free.
We enjoy blackened salmon on the grill almost every week during the summer. It’s incredibly easy to prepare, lusciously moist and super healthy. The recipe can be made for just 2 people and it’s just as easy to make a large grilled salmon for family and guests. Since I live at the beach we have lots of summer guest I love making this dish for them. It’s easy for me and everyone loves it.
If you don’t have a grill this recipe can be made in a cast iron or heavy saute pan. The original recipe created by Paul Prudhomme was made in a cast iron pan.
Spice makes food more interesting. I find when my food is interesting and flavorful I enjoy it more and feel incredibly satisfied!
A blackened spice mix can be purchased in many supermarkets. I buy Paul Prudhomme’s Blackened Redfish seasoning. It is all natural. Has no preservatives and no gluten. It uses regular salt instead of sea salt, but other than that it’s great. It’s super easy to use and can be used to flavor chicken, fish or vegetables with very little work.
Blackened Salmon Seasoning
Sometimes, when I have a lot of time, I make my own spice mix. It is a simple mixture of everyday spices that can be used on fish, shrimp, chicken or vegetables. I’ll make a large batch of the spice mix to keep on hand.
The best thing about making your own spice mix is you get to customize it. I like it spicy so I put in one teaspoon of cayenne, but if you prefer mild use only 1/4 teaspoon. I have included the basic recipe but if you want to change it up a bit, add cumin or chili powder or smoked paprika instead of plain paprika. The basic recipe below makes enough for 2 pounds of fish or chicken.
How to Blacken Salmon on the Grill
When grilling salmon leave the skin on. If I’m making 1 pound of salmon I’ll leave the fillet whole and cook it in one piece. If I’m grilling larger amounts I’ll cut them into 1 pound pieces. If the fillets are too big they’re hard to turn over.
Preheat your grill on high. Make sure your grates are clean.
Start by make sure your salmon is dry. I pat it with a clean kitchen towel.
Rub both sides of the salmon with a little olive oil.
Use a spoon to top each fillet with the spice mixture, then pat it with your fingers. You don’t have to put spice on the skin side.
Oil the grates, put the salmon fillets flesh (spice)-side down on the grill. Close the grill.
Grill for 3-4 minutes until the spices are just blackened and you can easily flip the fillet. If your salmon is sticking, let it cook another minute.
Flip it over and cook on the other side, with the grill closed, another 3-4 minutes depending on how thick your fillet is. Check your grill to make sure you don’t have any flare ups. Sometimes the fat from the salmon drips onto the grill making it flame up. If it does, sprinkle with a little water.
Salmon is best served medium rare. You want it to be rare in the middle when you remove it from the grill. It will continue to cook while it’s sitting on the plate. Salmon takes about 8 minutes per inch.
I have included directions for making Blackened Salmon in a cast iron pan with the recipe below.
Tips for Making Blackened Salmon on the Grill
- Keep the Salmon Cold. The oil will adhere better with cold fish, so keep the salmon in the refrigerator until you’re ready to start the recipe. You can put the spices on and then return it to the refrigerator if you’re not ready to put it on the grill.
- Have a HOT Grill or Pan. You want the grill or pan to be extra hot so the fish blackens properly and doesn’t stick.
- Oil Your Grill. Use a rag or paper towel dipped in oil to oil your grill right before putting the fish on.
- Don’t Move the Fish. Once you put the salmon on the don’t move it around. Let it cook for 3-4 minutes so it forms a nice spice crust and is easy to flip.
- Watch for Flare Ups. If the grill flames up from dripping salmon fat, sprinkle with water to prevent the salmon from burning.
- Don’t Overcook. Remove from the grill when it’s still a little rare in the middle.
What to Serve with Blackened Salmon
3 Ingredient Grilled Zucchini or grilled patty pan squash (as in the photos). Sautéed Patty Pan Squash with Tomatoes and Basil is a nice side dish too!
Roasted Jammy Tomatoes or grilled cherry tomatoes. If you grill the cherry tomatoes, leave them whole while grilling, turn them until slightly charred and a little tender.
Blackened Salmon on the Grill is a deliciously healthy dish. Keto, gluten free, dairy free, paleo and Whole30 compliant. Enjoy it all summer long on the grill. Make it in a cast iron pan in the winter.
