Grilled Fish With a Lemon-Caper Sauce

Total Time
Prep 10 mins
Cook 25 mins

This recipe works great with any firm, white fish. I recommend red snapper fillets, grouper fillets, or amberjack for saltwater fish. Catfish or tilapia for freshwater fish. The cooktime specified is for fillets about 1 inch thick, so adjust your cooking time accordingly. If you don't have a fish grilling basket, you can use a disposable aluminum pan...directions are included. Be sure to rinse the capers to remove the excess salt.

Ingredients Nutrition


  1. Brush your fish basket with oil, or if using a disposable 13X9X2 inch aluminum pan, brush it with 1/2 tsp olive oil. Place the fillets in the basket or pan -- do not overlap the fillets. Brush the fillets with 1 tbsp olive oil. Sprinkle fillets with dillweed, lemon-pepper seasoning, and salt.
  2. Place the pan on a grill rack; grill, covered, over medium-hot coals about 25 minutes (depends on the thickness of your fish fillets). Cook until the fish flakes easily when tested with a fork. Transfer fillets to a serving platter and keep warm.
  3. While the fish is on the grill, prepare your sauce. Saute the onion in 1 tbsp olive oil in a large skillet over medium-high heat, stirring constantly until tender. Remove from heat. Stir in the mayonnaise and next 5 ingredients. Cook over low heat, stirring frequently, just until heated. This process takes about 7 to 10 minutes, so start it according to the thickness of your fish.
  4. Arrange lemon and lime slices around the fillets. Garnish with parsley sprigs, if desired. Spoon the sauce over the fillets and serve.

Really delicious fish recipe! I was out of pimentos so had to skip them, otherwise made as directed. I used tilapia and the wonderful sauce was perfect with it. Thanks for sharing the recipe!

This is very tasty! I sautéed mine on the stovetop since I had other things cooking and couldn't go out to the grill. I used tilapia fillets and it paired well with the sauce. I did decrease the recipe for 2 fillets and used just 1/4 cup mayo. Will be making this again. Made for Spring Photo Tag.

Super fast and easy, very tasty. Tried it with catfish and it was delicious. Trying it tonight with striper. I left out the pimento since I don't keep any in the house, and probably tripled the capers because I love capers. Also skipped the fresh limes and lemons - gotta save the limes for G&T.
