Ingredients for Baked Cajun Salmon | Creamy Avocado Lime Sauce

Gather these simple ingredients – I promise your pantry probably has most of them already! Let’s break it down:

For the Salmon

• 4 salmon fillets (6 oz each), skin-on – trust me, that crispy skin is gold
• 2 tbsp Cajun seasoning – homemade or store-bought (but check those sodium levels!)
• 1 tbsp olive oil – just enough to help the spices stick

For That Dreamy Sauce

• 1 ripe avocado, peeled and pitted – the creamier the better
• 2 tbsp Greek yogurt (I use full-fat for extra richness)
• Juice of 1 lime – about 2 tbsp, but I always squeeze extra
• 1 garlic clove, minced – because everything’s better with garlic
• Salt and pepper to taste – start with a pinch and adjust
• Fresh cilantro for garnish – optional but oh-so-pretty

That’s it! Simple, fresh ingredients that pack a serious flavor punch when they come together.

How to Make Baked Cajun Salmon | Creamy Avocado Lime Sauce

Alright, let’s get cooking! This recipe flows like a well-choreographed dance – preheat, season, bake, blend. The timing works out perfectly so everything comes together hot and fresh. Here’s how we do it:

Prep the Salmon

First things first – crank that oven to 400°F (200°C). While it heats, line your baking sheet with parchment paper (trust me, this saves so much scrubbing later). Now for the fun part – grab those beautiful salmon fillets and pat them dry with paper towels. This helps the seasoning stick better. Drizzle with olive oil, then go to town with that Cajun seasoning! I like to really press it into the flesh with my fingers – you want every bite packed with flavor. Don’t be shy!

Bake the Salmon

Pop those seasoned fillets onto your prepared baking sheet (skin-side down if you left it on). Slide them into the preheated oven for 12-15 minutes. You’ll know they’re done when the salmon flakes easily with a fork and reaches 145°F internally. Pro tip: The edges will get slightly crispy – that’s the good stuff right there!

Make the Avocado Lime Sauce

While the salmon works its magic, let’s whip up that dreamy sauce. Toss the avocado, Greek yogurt, lime juice, garlic, salt and pepper into your blender or food processor. Blend until it’s silky smooth – I usually stop to scrape down the sides once. Taste and adjust – more lime for tang, more salt if needed. The sauce should be thick but pourable (add a splash of water if it’s too stiff).

Now just plate your gorgeous salmon, dollop with that vibrant green sauce, and garnish with cilantro if you’re feeling fancy. Dinner is served – in under 25 minutes flat!

Tips for Perfect Baked Cajun Salmon

Listen, I’ve made this salmon more times than I can count, and here are my hard-earned secrets: First, pat that salmon dry – moisture is the enemy of crispy edges! Second, check your oven temp with a thermometer – too hot and the spices burn, too cool and you’ll get sad, soggy fish. And here’s my favorite trick: let the salmon rest 2 minutes after baking – those juices redistribute beautifully. Oh, and always taste your Cajun seasoning first – some brands pack more heat than others!

Ingredient Substitutions

Ran out of something? No worries – this recipe is flexible! Swap Greek yogurt with plain yogurt (it’ll be a tad thinner but still delicious). If limes are MIA, lemon juice works in a pinch – just use a little less since it’s stronger. But here’s my rule: never use low-fat mayo in the sauce – it makes it weirdly watery. And if you’re out of fresh garlic? A quarter teaspoon of garlic powder will save the day!

Serving Suggestions for Baked Cajun Salmon

Oh, let’s talk about making this salmon shine even brighter! I love serving it over a bed of fluffy quinoa or brown rice – they soak up that amazing sauce like little flavor sponges. For veggie lovers, roasted asparagus or zucchini are perfect sidekicks. And if you’re craving something fresh? A simple arugula salad with cherry tomatoes and extra lime wedges cuts through the richness beautifully. Pro tip: Always put out extra lime wedges – my guests always end up squeezing more over everything!

Storage & Reheating

Here’s the deal – that avocado lime sauce turns brown if left too long, so store it separately in an airtight container with plastic wrap pressed right against the surface. The salmon keeps beautifully for 2 days in the fridge. When reheating, go low and slow – I pop it in a 300°F oven for about 8 minutes until just warmed through. Microwaving works in a pinch, but go easy – 30 second bursts to prevent overcooking!

Baked Cajun Salmon FAQs

Can I use frozen salmon? Absolutely! Just thaw it overnight in the fridge first – never cook salmon straight from frozen. Pat it extra dry before seasoning to prevent a soggy mess. I’ve made this with frozen fillets dozens of times when fresh wasn’t available.

Is the sauce spicy? Not at all! The avocado lime sauce is actually the cooling counterpoint to the Cajun spices. It’s creamy, tangy, and packed with fresh flavors that tame the heat. If you’re really sensitive to spice, just go lighter on the Cajun rub – the sauce will still be delicious!

Can I grill instead of baking? Oh yes! Grilling gives amazing smoky flavor. Just oil the grates well and cook over medium heat for about 4-5 minutes per side. The skin gets extra crispy this way – my favorite summer variation! Watch closely though – it cooks faster than baking.
