Ingredients
List of Ingredients
- 4 cod fillets (about 6 oz each)
- 4 tablespoons unsalted butter, melted
- 1 medium lemon, zested and juiced
- 2 garlic cloves, minced
- 1 teaspoon dried thyme
- 1 teaspoon smoked paprika
- Salt and pepper to taste
- Fresh parsley, chopped (for garnish)
Measurement Guide
When you gather your ingredients, measure carefully. Each cod fillet should weigh about 6 ounces. For the butter, use 4 tablespoons, which equals a 1/2 stick. A medium lemon gives you enough zest and juice for great flavor. Use 2 garlic cloves, minced small, to pack a punch. Thyme and smoked paprika each need 1 teaspoon. Adjust salt and pepper to your taste. Finally, chop fresh parsley for a bright garnish.
Substitutions
You can try different herbs. Instead of thyme, use dill or basil for a fresh twist. If you want a different fish, try salmon, halibut, or tilapia. Each will give you a unique taste. For a lighter butter flavor, swap unsalted butter with olive oil. You can also use lemon juice from a bottle if fresh lemons are not available. Each substitution will create a slight change, but the dish will still be tasty.

Step-by-Step Instructions
Prepping the Cod Fillets
First, I start by patting the cod fillets dry. This step helps the lemon butter stick well. I use paper towels to remove any excess moisture. Then, I place the fillets in a shallow dish. This makes it easy to coat them later.
Making the Lemon Butter Mixture
Next, I whisk together the melted butter, lemon zest, and lemon juice in a small bowl. Adding minced garlic, dried thyme, smoked paprika, salt, and pepper boosts the flavor. I mix this well until everything blends smoothly. This mixture gives the cod its rich taste.
Cooking in the Air Fryer
Now, I preheat the air fryer to 400°F (200°C) for about 5 minutes. While it heats, I pour the lemon butter mixture over the cod fillets. I let them marinate for 10 to 15 minutes. This marinating time allows the flavors to soak in.
Once the air fryer is ready, I lightly spray the basket with cooking oil. I place the marinated cod fillets in the basket, ensuring they don’t touch. This helps them cook evenly. I cook the fillets for 10 to 12 minutes. They are ready when they flake easily with a fork.
After cooking, I carefully remove the fillets and place them on a serving plate. I drizzle any leftover lemon butter from the basket on top. To finish, I sprinkle chopped parsley for a fresh touch. This dish looks as good as it tastes!
Tips & Tricks
How to Achieve the Best Flavors
To make your lemon butter cod shine, use fresh lemon juice and zest. This truly brings out the citrus notes. Make sure to mix the butter, garlic, thyme, and smoked paprika well. These spices add depth to the dish. Let the cod marinate for 10-15 minutes. This step helps the fish soak up all the lovely flavors.
Adjusting Cooking Times for Different Fillet Thicknesses
Cooking time is key for perfect cod. If your fillets are thicker than 1 inch, add a few extra minutes to the cook time. For thinner fillets, check them a minute or two early. The cod should flake easily with a fork when done. Always use a food thermometer to ensure the internal temperature reaches 145°F (63°C).
Recommended Cooking Accessories
Using an air fryer liner can make cleanup easier. It helps keep the basket clean and prevents sticking. A good pair of tongs is also helpful. They allow you to safely flip and remove the cod without breaking it apart. A basting brush can help you apply the lemon butter evenly.
Pro Tips
- Fresh Cod is Best: Always choose fresh cod fillets when possible for the best flavor and texture. Frozen cod can be used, but ensure it is fully thawed before cooking.
- Marinate for Flavor: Allow the cod to marinate for at least 15 minutes to soak up the lemon and garlic flavors. If time permits, marinating for up to an hour will enhance the taste even more.
- Check for Doneness: The cod is done when it flakes easily with a fork and is opaque throughout. Use a food thermometer to check that it reaches an internal temperature of 145°F (63°C).
- Customize the Seasoning: Feel free to experiment with different herbs and spices. Dill or basil can be great substitutions for thyme, and adding a pinch of chili flakes can give an extra kick!
Variations
Lemon Butter Cod with Additional Herbs
You can add more herbs to your lemon butter cod. Fresh dill or basil gives a nice twist. You can use rosemary for a woodsy flavor. Just chop them finely and mix them in the lemon butter. This makes the dish even brighter and more fragrant.
Spicy Lemon Butter Cod with a Kick
If you like heat, try adding red pepper flakes. Just a pinch will do. Mix them into the lemon butter before pouring it over the cod. For more spice, use hot sauce in the butter mix. This adds a fun layer of flavor to your dish.
Using Different Cooking Methods
Besides the air fryer, you can cook cod in the oven. Preheat your oven to 400°F (200°C) and bake the fillets for about 15-20 minutes. You can also pan-fry them in a skillet over medium heat. Just make sure to use enough lemon butter to keep them moist. Each method brings out different flavors in the cod.
Storage Info
Best Practices for Storing Leftovers
After enjoying the tender air fryer lemon butter cod fillets, you may have some leftovers. To store them, let the fillets cool down first. Then, place them in an airtight container. This will keep the cod fresh and tasty. You can also use plastic wrap, but make sure it is tight. Always label the container with the date. This helps you keep track of freshness.
Reheating Cod Fillets Safely
When you’re ready to enjoy the leftovers, reheating is simple. The best way is to use the air fryer. Preheat it to 350°F (175°C). Place the cod fillets in the basket and heat for about 5-8 minutes. This keeps the fillets moist and flaky. You can also use the microwave, but be careful. Heat them in short bursts to avoid drying them out. Cover the cod with a damp paper towel to retain moisture.

Use an airtight container to prevent freezer burn. Always label them with the date so you know when to use them.
