Ingredients
Serves: 4
- 4 white fish fillets (cod, haddock, tilapia, halibut, or pollock)

- ½ teaspoon dried parsley
- ½ teaspoon dried thyme
- ½ teaspoon salt
- ¼ teaspoon black pepper
- Lemon slices for serving
- Fresh parsley for garnish
Instructions
Step 1: Prepare the Fish
Pat the fish fillets dry using paper towels. Removing excess moisture helps the seasoning stick and promotes better browning.
Step 2: Make the Garlic Butter
In a small bowl, combine:
- Melted butter
- Garlic
- Lemon juice
- Paprika
- Garlic powder
- Onion powder
- Thyme
- Parsley
- Salt
- Pepper
Mix until well combined.
Step 3: Season the Fish
Brush both sides of each fillet generously with the garlic butter mixture.
Allow the fish to sit for about 5 minutes while the air fryer preheats.
Step 4: Preheat the Air Fryer
Preheat your air fryer to 200°C (400°F) for 3–5 minutes.
Step 5: Cook
Lightly spray the basket with cooking oil.
Arrange the fillets in a single layer.
Cook for 8–12 minutes, depending on thickness.
Halfway through cooking, brush with any remaining butter mixture.
The fish is ready when:
- It flakes easily with a fork.
- The internal temperature reaches 63°C (145°F).
Step 6: Serve
Serve immediately with:
- Lemon wedges
- Fresh parsley
- Extra melted butter if desired

Frequently Asked Questions
Can I use frozen fish?
Yes. Thaw completely and pat dry before seasoning for the best texture.
Do I need to flip the fish?
Most fillets do not need to be flipped, but very thick fillets may benefit from turning halfway through cooking.
How do I know when the fish is done?
The fish should flake easily with a fork and reach an internal temperature of 63°C (145°F).
Can I make this dairy-free?
Yes. Replace the butter with olive oil or a dairy-free butter alternative.
Which air fryer works best?
Basket-style and oven-style air fryers both work well. Cooking times may vary slightly depending on the model.
Can I use salmon instead?
Absolutely. Salmon cooks beautifully with the same garlic butter mixture, though it may require an additional 1–2 minutes depending on thickness.
Why is my fish sticking?
Lightly oil the basket and avoid moving the fish until it has cooked for a few minutes and naturally releases.
Can I prepare it ahead of time?
Yes. Season the fish up to 30 minutes in advance and refrigerate until ready to cook.
