Table of Contents
Table of Ingredients
| Ingredient | Amount | Notes/Links |
|---|---|---|
| Firm white fish fillets | 4 (about 6 inches long, 1-inch thick) | Cod, halibut, or mahi mahi recommended |
| Melted butter | 3 tbsp | Use unsalted for control |
| Lemon | Juice & zest from 1 medium | Organic for stronger flavor |
| Kosher salt | ½ tsp (divided) | |
| Paprika | 1 tsp | |
| Garlic powder | 1 tsp | |
| Onion powder | 1 tsp | |
| Black pepper | ¼ tsp | |
| Olive oil | 3 tbsp | |
| Fresh basil or parsley | For garnish | Optional |
| Extra lemon slices | For serving | Optional |
Step-by-Step Instructions
- Pat-dry the fish fillets thoroughly with paper towels. This crucial step ensures a brown, crispy exterior rather than steamed fish.
- In a bowl, mix melted butter, lemon juice, zest, and half the salt. Adjust salt as preferred after tasting.
- In another bowl, blend the remaining salt with paprika, garlic powder, onion powder, and pepper. Press this seasoning mixture onto all sides of the fillets.
- Add olive oil to a large, heavy pan and heat over medium-high. Once sizzling, cook two fillets at a time so each piece gets evenly browned.
- Cook each side for 2-3 minutes until opaque and browned. Drizzle some lemon butter sauce over fish while cooking; reserve the rest for serving. Don’t overcook!
- Taste and season with extra salt and pepper if desired.
- Serve the fish topped with remaining sauce, fresh herbs, and lemon wedges.

Helpful Cooking Tips

- For accuracy, measure ingredients with a measuring cups and spoons set.
- For extra convenience, chop herbs with a chef’s knife and serve on a cutting board.

Frequently Asked Questions
What kind of fish works best?
Firm white fillets like cod, halibut, or mahi mahi hold their shape and absorb lemon butter well.
Can I use an air fryer or oven?
Yes, baking is possible! Place fillets on a baking sheet and drizzle sauce; bake at 400°F until flaky about 10-12 minutes. For a crispier touch, try the air fryer for 8-10 minutes at 400°F.
How do I know the fish is done?
Fillets should be opaque and flake easily with a fork; avoid overcooking for best texture.
Can leftovers be saved?
Absolutely! Store in an airtight container for up to 2 days. Reheat gently to avoid rubbery texture.
