Ingredients
For the Fish
- 4 white fish fillets (about 150–180 g each), such as cod, tilapia, haddock, or snapper
- 2 tablespoons extra virgin olive oil
- 3 tablespoons unsalted butter
- 4 garlic cloves, finely minced
- 1 tablespoon fresh lemon juice
- 1 teaspoon smoked paprika
- 1 teaspoon Cajun seasoning (preferably low-sodium)
- ½ teaspoon ground black pepper
- ½ teaspoon onion powder
- ¼ teaspoon turmeric powder
- ¼ teaspoon dried oregano
- ¼ teaspoon chili flakes (optional)
- Salt to taste
- 2 tablespoons fresh chopped parsley
- 1 fresh lemon, cut into wedges
For the Garlic Butter Sauce
- 2 tablespoons unsalted butter
- 2 garlic cloves, minced
- 1 tablespoon lemon juice
- 1 tablespoon fresh parsley
- 1 teaspoon extra virgin olive oil
- A pinch of black pepper
Instructions
Step 1: Prepare the Fish
Pat the fish fillets dry using paper towels. Removing excess moisture helps the fish develop a beautiful golden surface during cooking.
Place the fillets on a plate or shallow dish.
Step 2: Prepare the Cajun Seasoning
In a small bowl, combine smoked paprika, Cajun seasoning, black pepper, onion powder, turmeric, oregano, and chili flakes.
Mix well to distribute the spices evenly.
Step 3: Season the Fish
Brush both sides of the fish fillets with olive oil.
Sprinkle the Cajun spice mixture evenly over the fillets. Add minced garlic and fresh lemon juice.
Gently rub the seasoning into the fish and allow it to rest for approximately 10 minutes.
Step 4: Prepare the Garlic Butter
Melt the butter in a small saucepan over low heat.
Add minced garlic and cook gently for approximately 30–60 seconds until fragrant. Avoid browning or burning the garlic.
Add lemon juice, olive oil, black pepper, and chopped parsley.
Stir until combined and set aside.
Step 5: Grill the Fish
Preheat a grill or grill pan to medium heat and lightly grease the cooking surface.
Place the seasoned fish fillets on the hot grill.
Cook for approximately 3–5 minutes per side, depending on thickness and fish variety.
Turn carefully using a wide spatula to prevent the fillets from breaking.
The fish is ready when it becomes opaque and flakes easily with a fork. For food safety, cook fish to an internal temperature of 145°F (63°C).
Step 6: Add Garlic Butter
During the final minute of cooking, brush the fish generously with the prepared garlic butter sauce.
Allow the butter, garlic, and Cajun spices to coat the surface.
Step 7: Garnish and Serve
Transfer the grilled fish fillets to a serving platter.
Sprinkle with freshly chopped parsley and drizzle with additional lemon garlic butter.
Garnish with fresh lemon wedges.
Serve immediately while warm.

Anti-Inflammatory Benefits
This recipe contains several ingredients that can contribute to a nutritious, anti-inflammatory dietary pattern.
1. Fish
Fish provides high-quality protein and important nutrients. Fatty fish such as salmon, sardines, and trout also provide omega-3 fatty acids, which support normal inflammatory regulation.
White fish such as cod and tilapia are lean protein sources but generally contain less omega-3 than oily fish.
2. Garlic
Garlic contains sulfur-containing compounds, including allicin-related compounds, that have antioxidant properties.
3. Extra Virgin Olive Oil
Extra virgin olive oil contains monounsaturated fats and polyphenols. Replacing some saturated fats with unsaturated fats can support cardiovascular health.
4. Turmeric
Turmeric contains curcumin, a naturally occurring compound studied for its antioxidant and anti-inflammatory properties.
5. Lemon Juice
Fresh lemon provides vitamin C, which contributes to normal immune function and protects cells against oxidative stress.
6. Fresh Parsley
Parsley provides vitamin K, vitamin C, and beneficial plant compounds.
Important: No single meal can treat or cure chronic inflammation. The benefits of an anti-inflammatory diet come from consistent eating patterns that include vegetables, fruits, whole grains, legumes, nuts, seeds, and healthy fats.
Recipe Variations
1. Healthy Cajun Salmon
Replace white fish with salmon fillets. Salmon provides more omega-3 fatty acids, making it an excellent option for an anti-inflammatory eating pattern.
2. Lemon Garlic Butter Cod
Use fresh cod fillets and reduce the Cajun seasoning slightly. Add extra lemon juice and parsley for a lighter flavor.
3. Dairy-Free Garlic Butter Fish
Replace butter with extra virgin olive oil or a suitable plant-based butter alternative.
4. Spicy Cajun Fish
Add extra cayenne pepper, chili flakes, and smoked paprika for a stronger spicy flavor.
5. Mediterranean Grilled Fish
Replace Cajun seasoning with oregano, thyme, rosemary, lemon zest, and black pepper. Finish with extra virgin olive oil.
6. Oven-Baked Garlic Butter Fish
Preheat the oven to 400°F (200°C). Arrange seasoned fillets in a lightly greased baking dish and bake for approximately 10–15 minutes, depending on thickness, until the fish reaches 145°F (63°C).
7. Low-Sodium Cajun Fish
Use homemade Cajun seasoning without added salt. Increase garlic, lemon, parsley, smoked paprika, and herbs to maintain excellent flavor.
Storage Instructions
Refrigeration: Store leftover cooked fish in an airtight container in the refrigerator for up to 3 days.
Reheating: Warm gently in a covered pan over low heat or in the microwave in short intervals. Avoid overheating because fish can become dry.
Freezing: For best texture, freeze uncooked seasoned fish separately from the garlic butter sauce. Thaw safely in the refrigerator before cooking.
