Prepare the fries:

Chill in the refrigerator until ready to serve.

Cook the cod:

In a small bowl, mix all spices for the blackened seasoning.
Pat the cod fillets dry and rub the seasoning on both sides.
Heat olive oil in a skillet over medium-high heat.
Sear the fillets for 3–4 minutes per side, until blackened and cooked through (internal temperature should reach 145°F/63°C).

Variations

Spicy Cajun Style: Increase cayenne and add a dash of hot sauce to the dipping sauce for extra heat.
Sweet Potato Fries: Substitute sweet potatoes for a sweeter contrast to the savory cod.
Grilled Cod Option: Grill the cod fillets instead of pan-searing for a slightly lighter take.
Tartar Sauce Swap: Serve with classic tartar sauce instead of the smoked paprika dip.
Lemon Herb Twist: Add lemon zest and fresh dill to the spice mix for a citrusy herbaceous profile.

storage/reheating

Storage:
Store any leftovers in airtight containers in the refrigerator for up to 2 days. Keep fries and cod separate for best texture.

Reheating:
Reheat the cod in a skillet over medium heat or in the oven at 350°F (175°C) for 10 minutes. Reheat fries in the oven or air fryer to restore crispness. Avoid microwaving as it can make both elements soggy.

FAQs

What is blackening in cooking?

Blackening is a cooking technique where fish or meat is coated in a spice mixture and seared in a hot pan to create a dark, flavorful crust.

Can I use frozen cod fillets?

Yes, but make sure to fully thaw and pat them dry before seasoning and cooking to prevent excess moisture.

What oil is best for frying the fries?

Vegetable oil or canola oil are ideal for frying due to their high smoke points and neutral flavor.

Can I bake the fries instead?

Yes. Toss the fries in a little oil, spread them on a baking sheet, and bake at 425°F (220°C) for 30–35 minutes, flipping halfway through.

Is this dish spicy?

The cod has a mild to moderate level of spice. You can adjust the cayenne pepper to suit your taste.

Can I use another type of fish?

Yes, you can substitute with haddock, tilapia, or snapper, though cooking times may vary slightly.

What should I serve with this dish?

A fresh side salad, coleslaw, or steamed vegetables pair well with the bold flavors of blackened cod and fries.

Can I air-fry the fries?

Yes, air-fry the potatoes at 375°F (190°C) for 20–25 minutes, shaking the basket halfway through, until crispy and golden.

How do I know the cod is cooked through?

Cod should be opaque and flake easily with a fork. Use a thermometer to ensure it reaches an internal temperature of 145°F (63°C).

Is this dish gluten-free?

Yes, the recipe is naturally gluten-free as it contains no flour or breading. Always check packaged ingredients to confirm.
