With a light crunch on the outside and a tender fish center, Grouper Bites are perfect as appetizers or as part of a larger meal. Serve them with arroz amarillo or arroz blanco (yellow or white rice), stewed beans, and an avocado wedge.

Want to make these Mero Fish Bites lower in carbs or even ketogenic?
If you want to keep it low-carb and use only flour, you can substitute regular flour with almond flour or coconut flour. Almond flour will give a more neutral flavor and a crunchy texture, while coconut flour will result in a slightly denser coating. Both are great low-carb options that will help you achieve a crispy texture without using traditional breadcrumbs.

Tartar sauce can be made ahead of time and chilled before service.
- Step 1: If the fish is frozen, thaw it out and pat it dry—option to add a light sprinkle of salt and maybe pepper.
- Step 2: In a small food processor. Chop garlic, peppercorns, and cilantro.
- Step 3: In a bowl, add flour, salt, cumin, and garlic/cilantro mix.
- Step 4: Add water. This is a light batter, but you can make it as thick as you desire by adding more or less water.
- Make tartar sauce: This sauce can be made ahead of time. Ingredients, top to bottom: mayonnaise, chopped pickles, and capers, chopped cilantro (option to use parsley), Worcestershire sauce, and lemon juice.
- Step 5: Mix all ingredients in a small bowl and chill until service.
- Step 6: Heat the oil. Using the Thermoworks Chefalarm or a probe thermometer, create a heating range of 350℉ (low)-375℉ (high). Or you can use a small fryer to control the temperature of the oil better.
- Step 7: Dip the fish in the batter. Option to lightly coat the fish with flour, but I do not find it necessary.
- Step 8: Deep fry the pieces until golden brown and crispy.
Top Tip: Extra Crunch
If you want your mero bites to have an extra crispy crunch, sprinkle a little bit of cornmeal into your batter. It’ll give the coating more texture and help achieve that perfect crunch.

Expert Tips
- Consistency is Key: When mixing your batter, make sure it’s thick enough to coat the fish but not too thick that it becomes doughy. A smooth, slightly thick batter is ideal for achieving that crispy, golden texture.
- Don’t Overcrowd the Pan: Fry the mero bites in batches. Overcrowding the pan can cause the temperature of the oil to drop, resulting in greasy, soggy bites rather than crispy ones.
- Low and Slow Frying: To get the perfect crispy texture without burning the pork, fry the chicharrón on medium-low heat. This allows the fat to render slowly, ensuring a crunchy, golden exterior while keeping the inside tender and juicy.
- Rest After Frying: Once the chicharrón is crispy, let it rest on a paper towel-lined plate for a minute or two. This helps absorb excess oil, maintaining its crispy texture and preventing it from becoming greasy.
Recipe FAQs
Yes, you can substitute grouper with another firm, white fish like cod, halibut, tilapia, or catfish. Please ensure the fish is cut into bite-sized chunks and has a similar texture to grouper for the best results.
The best method is frying them in hot oil to get that crispy, golden crust. However, you can also bake them at 400°F for a healthier version.
After frying, let the nuggets rest on a paper towel-lined plate to drain excess oil. For extra crispiness, use panko breadcrumbs in the coating.
It's best to serve them fresh, but you can prepare and coat the nuggets, par-fry them, and refrigerate them. Then, finish frying them when you're ready to serve.
Par-frying and refrigerating is a good method if you're looking to save time. It helps lock in the crispy texture and ensures the nuggets are fully cooked when you finish frying. Just make sure to let them cool completely before refrigerating to prevent sogginess. When reheating, fry them again at a high temperature to restore their crispiness.
Grouper nuggets pair well with tartar sauce, mayo-ketchup, mojito sauce, or a simple squeeze of lemon or lime for freshness.
