- Reheating: Air fry refrigerated cod at 300°F (150°C) for 3–5 minutes until warmed through.

A simple high-protein, low-carb dinner made with easy-to-find ingredients.📝 Ingredients- 2 cod fillets, about 6 ounces (170 g) each
- 1 tablespoon (15 ml) olive oil
- 1 tablespoon fresh lemon juice
- 1 teaspoon lemon zest
- 1 teaspoon garlic powder
- ½ teaspoon smoked paprika
- ½ teaspoon dried parsley
- ¼ teaspoon dried oregano
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 1 tablespoon fresh parsley, chopped — optional
- Lemon wedges, for serving
- Preheat the air fryer: Set the air fryer to 400°F (200°C) and preheat for 3 minutes.
A hot basket helps the fish begin cooking immediately. - Dry the cod: Pat the cod fillets thoroughly with paper towels.
Removing surface moisture helps the seasoning adhere and encourages light browning. - Make the seasoning: In a small bowl, combine olive oil, lemon juice, lemon zest, garlic powder, smoked paprika, parsley, oregano, salt, and black pepper.
Stir until a thin seasoned mixture forms. - Season the fish: Brush the mixture evenly over both sides of the cod.
Coat the surface without applying an excessively thick layer. - Prepare the basket: Lightly spray the air fryer basket or place a perforated piece of air-fryer parchment underneath the fillets.
This helps prevent sticking while maintaining airflow. - Air fry: Place the cod in a single layer and cook at 400°F (200°C) for 8–12 minutes.
Thinner fillets may finish sooner, while thicker pieces require additional time. - Check for doneness: The fish should look opaque and separate easily into moist flakes when gently tested with a fork.
For food safety, the thickest part should reach 145°F (63°C). - Avoid overcooking: Remove the fish promptly once it reaches the desired temperature.
Cod continues cooking slightly from residual heat. - Finish: Sprinkle with fresh parsley and squeeze fresh lemon juice over the top.
The citrus brightens the flavor and complements the mild fish. - High-protein serving tip: Pair the cod with steamed broccoli, asparagus, green beans, salad, or cauliflower rice for a protein-focused low-carb plate.
For a more substantial meal, add a moderate serving of potatoes, brown rice, or quinoa.
- Storage: Refrigerate cooked cod for up to 3 days in an airtight container.
- Freezing: Freeze individual portions for up to 2 months for best quality.
- Reheating: Air fry at 300°F (150°C) for 3–5 minutes to gently warm the fish.
- Allergy notes: Cod is a fish and common allergen; check packaged fish labels for cross-contact information.
- Frozen cod: Thaw completely and pat dry before seasoning for the best texture.
- Flavor boost: Add Cajun seasoning, chili flakes, dill, lemon pepper, or a little grated Parmesan.
- Lower-sodium option: Reduce the added salt and choose a low-sodium seasoning blend.
- Crispier finish: Lightly spray the seasoned surface with olive oil immediately before air frying.
- Protein tip: Keep the cod as the centerpiece and add vegetables or a high-protein side rather than relying on calorie-dense sauces.
