Step‑by‑Step Instructions for Cajun Salmon And Avocado Lime Sauce
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). While it heats, line a baking sheet with parchment paper for easy cleanup. This preparation ensures your salmon cooks evenly and prevents sticking, making it simpler to transfer the flaky Cajun salmon once baked.
Step 2: Prepare the Cajun Mixture
In a medium bowl, whisk together olive oil, Cajun seasoning, salt, and black pepper until well combined. This mixture will coat the salmon fillets, infusing them with bold, spicy flavors. Let the mixture sit for a few minutes while you prepare the salmon for baking.
Step 3: Season the Salmon
Place the salmon fillets skin-side down on the prepared baking sheet. Using a brush or spoon, evenly apply the Cajun mixture over the fillets, ensuring they are nicely coated. The vibrant colors will signal that they’re ready to bake, enhancing the flavor and aroma as they cook.
Step 4: Bake the Salmon
Bake the salmon in your preheated oven for 15-20 minutes, or until the fillets flake easily with a fork. Keep an eye on the edges; they should turn golden brown, providing a visual cue that your Cajun salmon is perfectly cooked. Consider checking the internal temperature, which should reach 145°F for best results.
Step 5: Make the Avocado Lime Sauce
While the salmon bakes, prepare the creamy Avocado Lime Sauce. In a mixing bowl, mash ripe avocado until smooth. Add lime juice, Greek yogurt, minced garlic, salt, and pepper, stirring until everything is well incorporated. The vibrant green of the avocado should shine through, promising a refreshing addition to your dish.
Step 6: Serve and Enjoy
Once the salmon is finished baking, allow it to rest for a few minutes. This step helps to keep the fish moist. Serve the flaky Cajun salmon with a generous drizzle of the Avocado Lime Sauce on top. The combination creates a beautiful presentation, bursting with flavors that will enhance your dining experience.

Cajun Salmon and Avocado Lime Sauce Recipe FAQs
How do I choose the best ripe avocado?
Look for avocados that yield slightly to gentle pressure but are not overly soft. Ideally, the skin should be dark green to almost black, and there shouldn’t be any dark spots all over, which may indicate overripeness. Avoid hard avocados as they won’t have the desired creamy texture for your sauce.
What’s the best way to store leftover Cajun salmon?
Store leftover Cajun salmon in a sealed container in the refrigerator for up to 2 days. Ensure the salmon has cooled completely first, and if you’re worried about dryness, wrap it in foil before placing it in the container to help retain moisture.
Can I freeze the Cajun salmon?
Absolutely! To freeze, allow the cooked salmon to cool completely, then transfer it into an airtight container or a freezer bag, removing as much air as possible before sealing. The salmon can be safely frozen for up to 3 months. When you’re ready to enjoy it, thaw it overnight in the fridge, then reheat at 350°F (175°C) for about 8 minutes until warmed through.
What if my avocado lime sauce turns brown?
It’s normal for the avocado in the lime sauce to brown quickly due to oxidation. To prevent this, cover the sauce tightly with plastic wrap directly on the surface, preventing exposure to air. If it has already turned brown, you can stir in a bit of lime juice to brighten up the flavor again!
Can I make substitutions if I have allergies?
Certainly! If you’re avoiding dairy, you can substitute Greek yogurt with a dairy-free yogurt, which will still give you that creamy texture. For those needing a gluten-free option, feel free to use gluten-free Cajun seasoning, ensuring your meal accommodates any dietary restrictions while still being delicious.
How can I tell if my salmon is cooked perfectly?
The best way to check is using an instant-read thermometer, which should register 145°F (63°C) in the thickest part of the fillet. If you don’t have a thermometer, look for the salmon to flake easily with a fork, with the edges becoming golden brown—this is a sign of perfectly cooked Cajun salmon!
