Ingredients

For the Blackened Cod Bites

• 1½ pounds cod fillets, skin removed
• 2 tablespoons olive oil
• 1 teaspoon smoked paprika
• 1 teaspoon paprika
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• ½ teaspoon dried thyme
• ½ teaspoon dried oregano
• ½ teaspoon cayenne pepper (adjust to taste)
• ½ teaspoon black pepper
• ¾ teaspoon salt

For the Lemon Garlic Aioli

• ½ cup mayonnaise
• 2 garlic cloves, minced
• 1 tablespoon lemon juice
• 1 teaspoon lemon zest
• ½ teaspoon Dijon mustard
• Pinch of salt
• Pinch of black pepper

Optional Garnishes

• Chopped parsley
• Lemon wedges
• Extra aioli for dipping

Instructions

Step 1: Prepare the Cod

Pat the cod fillets dry with paper towels. Cut into bite-sized cubes, about 1 to 1½ inches each.

Drying the fish helps create a better crust when cooking.

Step 2: Make the Blackening Seasoning

In a small bowl, combine:

• smoked paprika
• paprika
• garlic powder
• onion powder
• thyme
• oregano
• cayenne
• black pepper
• salt

Mix thoroughly.

Step 3: Season the Fish

Place the cod bites in a large bowl. Drizzle with olive oil and toss gently.

Sprinkle the seasoning mixture over the fish and coat evenly.

Step 4: Cook the Cod

Heat a large skillet or cast-iron pan over medium-high heat.

Add the cod bites in a single layer without overcrowding the pan.

Cook for:

• 2–3 minutes per side
• until blackened and cooked through

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

Step 5: Make the Lemon Garlic Aioli

In a small bowl, whisk together:

• mayonnaise
• garlic
• lemon juice
• lemon zest
• Dijon mustard
• salt
• pepper

Taste and adjust lemon or seasoning as desired.

Step 6: Serve

Serve the hot blackened cod bites immediately with lemon garlic aioli on the side.

Garnish with parsley and lemon wedges if desired.

Serving Suggestions

These cod bites pair well with:

• roasted vegetables
• rice bowls
• coleslaw
• fries
• tacos
• fresh salads
• grilled corn
• mashed potatoes

They also work wonderfully in wraps or lettuce cups.

Recipe Notes

• Cod is mild and flaky, making it perfect for bold blackened seasoning.
• Cast-iron pans create the best blackened crust.
• Avoid overcooking; cod becomes dry quickly.
• Fresh lemon juice gives the aioli brighter flavor than bottled juice.
• If using frozen cod, thaw completely and pat dry before seasoning.

Tips for Success

1. Dry the Fish Well

Moisture prevents proper browning and crust formation.

2. Don’t Overcrowd the Pan

Cook in batches if needed to maintain high heat.

3. Adjust Spice Level

Reduce cayenne for milder bites or increase for extra heat.

4. Let the Pan Get Hot

A properly heated pan gives the signature blackened exterior.

5. Make Aioli Ahead

The aioli tastes even better after chilling for 20–30 minutes.
