Ingredients You’ll Need
Getting your ingredients right is the heart of this recipe. Each item plays a key role, whether adding spice, creaminess, crunch, or brightness to the dish. Having fresh produce and good-quality salmon really elevates the final result.
- 4 pieces salmon fillets (6 oz each), skin-on preferred: Skin-on gives a nice crispy texture and keeps the fish juicy.
- 4 tsp Cajun seasoning: The star spice blend that adds smoky, paprika-rich heat.
- 1 tbsp cooking oil: Use a neutral oil that can withstand high heat, like canola or avocado oil.
- 2 avocados, diced: Creamy and cooling, perfect to balance the Cajun kick.
- 1 cup cucumber, diced: Adds refreshing crunch and subtle flavor contrast.
- 1/4 cup red onion: Sharpness and slight sweetness for depth.
- 1/4 cup green onion: Mild, fresh onion flavor that complements the salsa.
- 1 jalapeño, finely diced: Adds a gentle heat and brightness – remove seeds if you want less spice.
- 1 tbsp cilantro, chopped: Herbaceous and aromatic, tying all the salsa notes together.
- 1 tbsp parsley, chopped: Adds a fresh, slightly peppery hint to the salsa.
- 1 tbsp lime juice: For acidity and zing that wake up the flavors.
- 1 tbsp lemon juice: Adds another layer of citrus brightness.
- Salt to taste: Essential for balancing all the flavors perfectly.
How to Make Cajun Salmon with Fresh Avocado Salsa Recipe
Step 1: Season and Prep
Start by generously seasoning both sides of your salmon fillets with the Cajun seasoning. This rub is what creates that irresistible crust once cooked. While the fish sits for a few minutes to soak in the flavors, dice the avocados, cucumber, red and green onions, and jalapeño. Chop your cilantro and parsley too. This hands-on prep is quick and helps all the fresh ingredients come together smoothly when making the salsa.
Step 2: Cook the Salmon
Heat your cooking oil in a skillet over medium-high heat until shimmering. Carefully place the salmon fillets skin-side down first. Cook for about 3 to 4 minutes on each side, or until the outside is golden and slightly blackened from the Cajun spices. The salmon should flake easily but still be moist and tender inside. This sear locks in juiciness while delivering that smoky flavor the recipe is known for.
Step 3: Prepare the Fresh Avocado Salsa
In a bowl, gently combine the diced avocado, cucumber, red and green onions, jalapeño, chopped herbs, lime juice, and lemon juice. Stir carefully so that the avocados hold their shape and don’t turn to mush. The salsa is a vibrant mix of textures and flavors – creamy avocado, crisp cucumber, spicy jalapeño, and zesty citrus.
Step 4: Season and Serve
Finish your salsa by seasoning it with salt to taste. Immediately serve the fresh avocado salsa spooned generously over the warm Cajun salmon fillets. Take a moment to taste and adjust the seasoning if needed – the combination of spicy, creamy, and tangy makes every bite exciting.
How to Serve Cajun Salmon with Fresh Avocado Salsa Recipe
Garnishes
A simple garnish like an extra sprig of cilantro or a small wedge of lime brings a bright, fresh touch. If you’re feeling adventurous, a scattering of toasted pumpkin seeds or some sliced radishes adds beautiful crunch and color contrast.
Side Dishes
This dish pairs wonderfully with light, fresh sides. Think fluffy quinoa tossed with herbs, a crisp green salad, or even some roasted sweet potatoes to complement the smoky heat of the salmon. The fresh avocado salsa and salmon shine brightest when served with simple, clean flavors.
Creative Ways to Present
For a fun twist, serve the Cajun Salmon with Fresh Avocado Salsa Recipe as a taco filling with warm corn tortillas and a drizzle of lime crema. Alternatively, create a colorful grain bowl layering the salmon and salsa over brown rice or farro with some leafy greens on the side. Presentation can completely transform the dining experience!
Make Ahead and Storage
Storing Leftovers
Place leftover salmon and salsa in separate airtight containers and refrigerate. The salmon keeps well for up to two days, but the fresh avocado salsa is best enjoyed within 24 hours to maintain its bright flavor and creamy texture.
Freezing
While you can freeze cooked salmon, it’s not recommended to freeze the avocado salsa as the texture changes dramatically upon thawing. If you want to prep ahead, freeze the salmon unseasoned and thaw before cooking fresh salsa.
Reheating
To reheat the salmon, gently warm it in a skillet over low heat or in the oven at a low temperature to avoid drying it out. Add the avocado salsa fresh after reheating for the best taste and texture contrast.
FAQs
Can I use frozen salmon for this recipe?
Yes! Just thaw the salmon completely and pat it dry before seasoning and cooking. Using fresh or high-quality frozen salmon will both work well here.
What if I don’t have Cajun seasoning?
You can easily make your own blend with paprika, cayenne, garlic powder, onion powder, thyme, oregano, salt, and pepper. Adjust the spice level to your taste.
Is this recipe very spicy?
The heat comes mainly from the Cajun seasoning and jalapeño, but you can control the spice by reducing the jalapeño or using a milder seasoning blend if preferred.
Can I prepare the salsa in advance?
You can prep the ingredients ahead, but it’s best to mix the salsa and add salt just before serving to keep it fresh and avoid browning of the avocado.
What other types of fish work in this recipe?
Firm, meaty fish like trout, halibut, or cod can be used with the same season and salsa for a delightful twist.

Ingredients
For the Salmon
- 4 pieces salmon fillets (6 oz each), skin-on preferred
- 4 tsp Cajun seasoning
- 1 tbsp cooking oil
For the Avocado Salsa
- 2 avocados, diced
- 1 cup cucumber, diced
- 1/4 cup red onion, diced
- 1/4 cup green onion, chopped
- 1 jalapeño, finely diced
- 1 tbsp cilantro, chopped
- 1 tbsp parsley, chopped
- 1 tbsp lime juice
- 1 tbsp lemon juice
- Salt to taste
Instructions
- Season the Salmon: Season the salmon fillets evenly on both sides with Cajun seasoning. Meanwhile, dice all the vegetables and herbs needed for the salsa. Allow the salmon to rest for about 3 minutes so the seasoning penetrates while you prepare the salsa ingredients.
- Cook the Salmon: Heat the cooking oil in a skillet over medium-high heat. Once hot, add the salmon fillets skin-side down and cook for 3-4 minutes until the skin is golden brown and slightly blackened. Flip and cook the other side similarly, ensuring the salmon is cooked through but remains moist.
- Prepare the Avocado Salsa: In a bowl, gently combine the diced avocado, cucumber, red and green onions, finely diced jalapeño, chopped cilantro and parsley, lime juice, and lemon juice. Mix carefully to avoid mashing the avocado, aiming for a fresh and chunky salsa texture.
- Season and Serve: Season the avocado salsa with salt to taste. Serve the salsa immediately over the warm pan-seared salmon fillets. Adjust seasoning if needed and enjoy immediately for the best flavor and texture.
Notes
- Use skin-on salmon for better texture and to help keep the fillets intact while cooking.
- If you prefer less heat, remove the seeds from the jalapeño before dicing.
- Ensure the skillet is adequately heated before adding the salmon to get a good sear.
- Serve with a side of steamed vegetables or a light salad for a complete meal.
- Leftovers can be stored separately: refrigerate cooked salmon and salsa in airtight containers for up to 2 days.
