About This Recipe

This Keto Spicy Cajun Salmon with Creamy Spinach is a perfect combination of heat, richness, and comfort — all while staying low-carb. Each bite delivers flaky, perfectly cooked salmon coated in smoky Cajun seasoning, balanced by a luscious, garlicky spinach cream sauce. It’s the kind of dish that looks fancy enough for a dinner date but is easy enough to make on a weeknight.

What makes this recipe stand out is its flavor balance: spicy paprika and cayenne from the Cajun mix meet the smooth, buttery texture of the cream sauce. The spinach absorbs every bit of that creamy, garlicky goodness, creating a perfect base for the salmon. You can serve it as-is or pair it with a light side like cauliflower mash or zucchini noodles for a complete meal.

This dish also supports your keto goals beautifully — high in healthy fats from salmon and cream, moderate in protein, and minimal in carbs. It’s a nutrient-dense powerhouse, packed with omega-3s, B vitamins, and antioxidants from spinach.

Whether you’re cooking for yourself, your family, or to impress guests, this Cajun salmon dish is guaranteed to impress — vibrant, flavorful, and guilt-free. The creamy sauce also makes it perfect for meal prep since it reheats beautifully without drying out the fish.

It’s one of those recipes that feels indulgent but keeps you 100% keto — and once you try it, you’ll want it in your weekly rotation.
