Grilled Lemon Herb White Fish Fillets are a fresh dinner made with white fish, olive oil, lemon juice, lemon zest, thyme, parsley, and garlic powder.
The ingredient list is short, but it still gives the fish a clean, bright taste that doesn’t feel heavy.
This is a nice recipe for busy nights, warm weather dinners, or any time you want grilled fish without a lot of extras.
Serve it with rice, roasted potatoes, salad, grilled vegetables, or whatever side dish is already in your kitchen.
You can use cod, halibut, haddock, tilapia, or another firm white fish that holds together well. The lemon and herbs keep the recipe fresh, and the grill gives the fish a nice finish.
Keep a small mixing bowl, basting brush, and tongs nearby so everything is ready when the fish goes on the grill.

- ½ teaspoon garlic powder

- Brush both sides of each fillet with the lemon herb mixture.
- Place the fillets directly on the grill. Cook for 3 to 4 minutes per side, depending on thickness. The fish should be opaque and flake easily with a fork.
