how to make Baked Cajun Salmon with Creamy Avocado Lime Sauce

You season the salmon and bake it until it flakes. While it cooks, you blend the avocado, lime, and sour cream to make the sauce. After baking, spoon the sauce over the hot salmon and add cilantro. This method keeps the fish moist and adds fresh, bright flavor.

2 tablespoons Cajun seasoning
2 avocados
1 lime (juiced)
1/4 cup sour cream or Greek yogurt
Salt and pepper to taste

Directions :

Preheat your oven to 400°F (200°C).
Place salmon fillets on a baking sheet lined with parchment paper.
Drizzle salmon with olive oil and season with Cajun seasoning.
Bake for 12-15 minutes, until the salmon is cooked through.
While the salmon is baking, prepare the avocado lime sauce by blending avocados, lime juice, sour cream, salt, and pepper until smooth.
Once the salmon is done, remove from oven and top with creamy avocado lime sauce.
Garnish with fresh cilantro and serve immediately.

FAQs

Q: Can I use frozen salmon?
A: Yes. Thaw the salmon fully and pat dry before seasoning and baking.

Q: Can I make the sauce ahead?
A: Yes. Make the sauce up to a day ahead and keep chilled in an airtight container. Stir before serving.

Q: Is this safe for kids who don’t like spicy food?
A: You can reduce the Cajun seasoning or use half the amount to lower the heat.

Q: Can I use lemon instead of lime?
A: Yes. Lemon works fine but lime gives a brighter, slightly sweeter taste.
