Instructions

Step 1: Season the Fish

Pat the fish fillets dry with paper towels.

In a small bowl, combine:

Paprika
Garlic powder
Onion powder
Cayenne pepper
Salt
Black pepper

Brush the fillets with olive oil and coat evenly with the seasoning mixture.

Set aside while preparing the fries.

Step 2: Prepare the Seasoned Fries

Preheat the oven to 425°F (220°C).

Place the potato fries in a large bowl and toss with:

Vegetable oil
Paprika
Salt

Arrange the fries in a single layer on a baking sheet lined with parchment paper.

Bake for 35–40 minutes, turning halfway through cooking, until golden brown and crispy.

Step 3: Cook the Cajun Fish

Heat a large skillet over medium-high heat.

Add a small drizzle of olive oil.

Cook the fish fillets for 3–4 minutes per side, depending on thickness, until golden on the outside and flaky inside.

The fish should easily separate with a fork and reach an internal temperature of 145°F (63°C).

Sprinkle with chopped parsley before serving.

Step 4: Make the Herb Sauce

In a small bowl, whisk together:

Mayonnaise
Sour cream
Fresh dill
Fresh parsley
Minced garlic
Lemon juice

Season with salt and black pepper to taste.

Refrigerate until ready to serve.

Step 5: Prepare the Garden Salad

In a large bowl, combine:

Lettuce
Cucumber
Tomatoes
Onion rings

Drizzle with olive oil and season with salt and pepper.

Toss gently to combine.

Step 6: Assemble and Serve

Arrange the Cajun fish fillets on serving plates.

Add a generous portion of seasoned fries and fresh salad.

Serve with a bowl of creamy herb sauce on the side for dipping.

Garnish with additional parsley and lemon wedges if desired.

Expert Tips for Perfect Cajun Fish

Pat the fish dry before seasoning to achieve a better crust.
Use fresh fish whenever possible for the best texture and flavor.
Avoid overcrowding the skillet to ensure even browning.
Soak the cut potatoes in cold water for 30 minutes before baking for extra crispy fries.
Fresh dill and parsley create the most flavorful herb sauce.

Recipe Variations

Spicy Cajun Fish

Add extra cayenne pepper or a pinch of Cajun seasoning for more heat.

Air Fryer Version

Cook the fries and fish in an air fryer for a crispier, lighter meal.

Grilled Cajun Fish

Grill the seasoned fish fillets instead of pan-searing for a smoky flavor.

Greek Yogurt Herb Sauce

Replace the mayonnaise and sour cream with Greek yogurt for a lighter sauce.

Storage and Reheating

Refrigerate

Store leftover fish, fries, and sauce separately in airtight containers for up to 3 days.

Reheat

Warm the fish and fries in a 375°F (190°C) oven for 8–10 minutes to maintain crispness.

Avoid Freezing

The herb sauce and fresh salad are best prepared fresh and are not recommended for freezing.
