Ingredients for Grilled Lime Fish Fillets

You only need a handful of ingredients to make these zesty grilled fish fillets. Simple ingredients, big flavor, no culinary gymnastics required.

• 2 pounds fish fillets, thawed: Mild white fish works beautifully here. Fresh fish is wonderful, but thawed frozen fillets are convenient and budget-friendly.
• Canola oil: A light brushing helps prevent sticking and keeps the fish from drying out on the grill.
• Paprika: Adds color and a gentle smoky-sweet flavor.
• 1/2 cup unsalted butter, melted: This creates the rich base for the lime butter glaze.
• 1/4 cup fresh lime juice: Freshly squeezed lime juice gives the fish its bright, citrusy flavor.
• Salt and pepper: Simple seasoning lets the lime and butter shine.
• Lime wedges, for serving: Because a little extra squeeze of lime at the table is never a bad idea.
• Optional sides: White rice, wild rice, grilled vegetables, corn on the cob, potato salad, or a fresh summer salsa.

Best Fish to Use for Grilled Lime Fish Fillets

For this recipe, choose a mild fish that will cook quickly and pair well with citrus. White fish is a natural fit because it has a delicate flavor that lets the lime butter glaze do its delicious little happy dance.

Good options include:

• Cod
• Tilapia
• Snapper
• Haddock
• Halibut
• Mahi mahi

If your fillets are very thin, watch them closely because they will cook quickly. If they are thicker, they may need a few extra minutes on the grill. Either way, the fish is done when it flakes easily with a fork and reaches an internal temperature of 145°F.

How to Make Grilled Lime Fish Fillets

These instructions are written to be clear, scannable, and easy to follow so the recipe works well for readers and recipe schema.

1. Preheat the grill. Heat the grill to medium, about 350°F to 375°F. Oil the grill grates well to help prevent the fish from sticking. A grill basket also works well for delicate fillets.
2. Prepare the lime butter glaze. In a small bowl, stir together the melted butter and fresh lime juice. Set aside for basting.
3. Prep the fish fillets. Pat the fish dry with paper towels. Lightly brush each fillet with canola oil, then sprinkle with paprika.
4. Grill the fish. Place the fillets on the prepared grill, about 3 to 4 inches from medium heat. Grill for 5 to 7 minutes per side, depending on thickness.
5. Baste while grilling. Brush the fish frequently with the melted butter and lime juice mixture as it cooks. This helps keep the fish moist and adds bright citrus flavor.
6. Check for doneness. The fish is ready when it flakes easily with a fork and reaches an internal temperature of 145°F.
7. Season and serve. Sprinkle the grilled fish lightly with salt and pepper. Serve warm with fresh lime wedges and your favorite summer sides.

Can You Broil This Fish Instead of Grilling?

Yes, you can make these lime fish fillets under the broiler if the weather refuses to cooperate or the grill is already occupied by burgers, hot dogs, and someone’s “famous” chicken.

To broil the fish, place the prepared fillets on a lightly oiled broiler pan or foil-lined baking sheet. Broil a few inches from the heat for 5 to 7 minutes per side, basting with the lime butter mixture as the fish cooks. Keep a close eye on it because fish can go from perfectly flaky to overdone faster than someone can ask, “Is dinner ready yet?”

Expert Tips for Perfect Grilled Fish

• Pat the fish dry before grilling. Removing excess moisture helps the oil, paprika, and glaze cling better to the fillets.
• Oil the grates well. Fish is delicate, and well-oiled grates help prevent tearing when you flip it.
• Use a grill basket for thinner fillets. A basket makes it easier to flip delicate fish without losing pieces to the grill gods.
• Do not overcook the fish. Fish continues to cook slightly after it comes off the grill, so remove it as soon as it flakes easily.
• Use fresh lime juice when possible. Bottled lime juice works in a pinch, but fresh lime juice gives the glaze a brighter flavor.
• Baste, but do not drown. Brush the fish with the lime butter glaze several times while it cooks, but avoid soaking it so heavily that it causes flare-ups.

Flavor Variations and Creative Ideas

This recipe is simple on purpose, but it also gives you plenty of room to play with flavor. Once you have the basic lime butter grilled fish down, try one of these easy variations.

• Garlic lime fish: Add 1 minced garlic clove or 1/2 teaspoon garlic powder to the melted butter and lime juice.
• Spicy lime fish: Add a pinch of cayenne pepper, chili powder, or crushed red pepper flakes to the glaze.
• Herb lime fish: Finish the grilled fish with chopped cilantro, parsley, or dill.
• Smoky citrus fish: Use smoked paprika instead of regular paprika for deeper grill flavor.
• Taco-style fish: Flake the grilled lime fish into warm tortillas and top with slaw, avocado, or Pineapple Mango Salsa.
• Rice bowl fish: Serve the fillets over rice with grilled vegetables, lime wedges, and a drizzle of the extra lime butter.

What to Serve with Grilled Lime Fish Fillets

Make-Ahead and Storage Tips

Fish is best served fresh from the grill, but you can still do a little prep ahead to make dinner easier.

• Prep the glaze ahead: Melt the butter and mix it with lime juice shortly before grilling. If made ahead and chilled, rewarm gently before using.
• Thaw frozen fish safely: Thaw frozen fillets in the refrigerator overnight, then pat dry before grilling.
• Store leftovers: Keep leftover grilled fish in an airtight container in the refrigerator for up to 2 days.
• Reheat gently: Warm leftovers in a covered skillet over low heat or in the oven at a low temperature until just heated through.
• Use leftovers creatively: Flake leftover fish into tacos, rice bowls, salads, or wraps.
