How to make Blackened Salmon: step-by-step guide

Cooking methods

  • Pan-searing
  • Steaming

Preparation steps

  1. Gather and measure all the ingredients.
  2. Defrost the salmon filets if frozen. Pat them dry with paper towels.
  3. Melt ½ cup unsalted butter in a microwave or a small saucepan and set it aside.
  4. Wash a medium-sized broccoli head, pat it dry, and cut it into florets.
  5. Squeeze out four tablespoons of fresh lemon juice and discard the seeds.

Cooking instructions

Cook the salmon filets

  1. Mix paprika, cayenne pepper, onion powder, salt, white and black pepper, thyme, basil, and oregano in a small bowl. Mix them to make the blackened salmon seasoning.
  2. Lay the salmon filets skin side down on a tray.
  3. Brush both sides of the filets with ¼ cup of melted butter. Sprinkle and press the seasoning onto the meat side, ensuring it’s fully coated.
  4. Melt two tablespoons of butter in a large cast-iron skillet over high heat.
  5. Place the filets in the skillet, skin side down, and cook for 2-5 minutes until blackened.
  6. Flip the filets, add the remaining butter, and cook for 3 to 5 minutes until the flesh side is blackened and flaky.

Cook the broccoli florets

  1. Steam or blanch the broccoli florets until they’re tender but still crisp. Drain any leftover water.
  2. Melt a tablespoon of butter in the same saucepan on medium heat. Add the steamed broccoli, stirring until it’s coated with butter.
  3. Squeeze fresh lemon juice over the broccoli, then add sea salt and black pepper to taste.
  4. Take the saucepan off the heat, and serve the lemon-butter broccoli with the blackened salmon filets. Enjoy!

Chef’s pro tip

Before cooking the salmon, get that skillet nice and hot. A hot pan gives you that perfect crispy edge on the filets. Keep an eye on them to avoid overcooking. Pull them off the heat slightly before they’re done. Let them sit for a few minutes to finish cooking. They’ll be spot-on when it’s time to dig in!

What to serve with blackened salmon?

The blackened salmon in a cast iron skillet is delicious on its own, but you can make the meal even more exciting with these keto-friendly dishes:

  • Cauliflower Rice: Fluffy cauliflower rice goes perfectly with the salmon and broccoli, helping to soak up all those delicious flavors.
  • Keto Kale Salad: A simple salad with curly kale, fresh lemon juice, garlic salt, and Parmesan cheese can add an irresistible flavor to your meal.
  • Crack Slaw: This cool and creamy dish contrasts with the bold flavors of the spicy salmon, making the meal even more enjoyable.
  • Asparagus Spears: The gentle taste of asparagus, whether grilled or steamed, pairs wonderfully with this dish, adding another layer of flavor and texture.

How to make it healthier?

You can make this dish even healthier by using less salt. Instead, focus on other flavorful spices to keep the taste just right.

Time-saving tips

  • Buy pre-cut broccoli: Save time chopping by picking up pre-cut broccoli florets from the store.
  • Use a pre-made spice mix: To make the recipe faster, buy ready-made blackening or Cajun spice mixes at your local grocery store.

What can I prepare ahead of time?

  • Make the seasoning early: If you decide not to use a pre-made mix, you can create the blackening seasoning beforehand. Just store it in a small container or ziplock bag.
  • Prep the broccoli: Wash and chop the broccoli into florets in advance, and keep them fresh in an airtight container or resealable bag in the fridge.

Storage and reheating instructions

Storage tips

  • Refrigerator: Put any leftover salmon filets and broccoli in separate airtight containers. This way, they’ll stay fresh for 2-3 days in the fridge.
  • Freezer: You can put the leftover salmon filets in freezer-safe bags, and they’ll last for 1-2 months. Be careful with the broccoli; freezing can make it lose its crispness.

Reheating best practices

  • Microwave: Place the leftover filets and broccoli in separate microwave-safe dishes. Cover them and heat on medium, checking and stirring now and then so they don’t overcook.
  • Stovetop: Reheat the leftovers in a non-stick pan over medium-high heat, flipping them occasionally. In another pan, gently heat the broccoli with a little water or olive oil until warm. This way, both will keep their nice textures.
  • Oven: Set your oven to 275°F (135°C) for a gentle reheat. Put the salmon and broccoli on separate trays and cover them with foil so they don’t dry out. Warm them for just a few minutes, and they’ll be ready to enjoy again.
