Grilled Fillet of Grouper With Roasted Cipollini and Tomatoes

The first time I tasted grouper prepared this way, I was on a small, sun-drenched patio overlooking the turquoise waters of the Florida Keys. The salty air mingled with the aroma of roasting garlic and herbs, creating an intoxicating blend. Every bite was an explosion of flavors – the delicate, flaky fish, the sweetness of the caramelized onions, and the bright, acidic pop of the tomatoes. It was more than just a meal; it was a memory etched in my senses, and I’ve been chasing that culinary experience ever since.

Equipment Needed

Small saucepan
Mortar and pestle
Plastic wrap
Oven
Skillet
Medium pan
Sterilized jar

Instructions

Prepare the Garlic Confit: Heat 1 cup of olive oil and 12 peeled garlic cloves in a small saucepan over low heat. Cook until the garlic is tender, about 30 minutes. Set aside.
Marinate the Grouper: In a mortar and pestle, mix 1 1/2 tablespoons of olive oil with the 4 minced garlic cloves, minced rosemary, minced thyme, and minced chili pepper. Rub the mixture all over the fish fillets, ensuring both sides are coated. Cover with plastic wrap and refrigerate for 1 hour.
Preheat the Oven: Preheat your oven to 350 degrees F (180 degrees C).
Sear the Grouper: Heat the remaining 1 1/2 tablespoons of olive oil in a skillet over medium-high heat. Sprinkle the grouper with salt and pepper. Sear the fish on the skin side until crisp and golden brown, about 5 minutes. Place the skillet with the grouper in the preheated oven and continue cooking until the flesh is flaky, about 25 minutes. A good indication of doneness is when the internal temperature reaches 145°F (63°C).
Roast the Cipollini and Tomatoes: Heat 1 tablespoon of olive oil in a medium pan over medium-high heat. Add the 24 cipollini onions and cook until tender, about 15 minutes, stirring occasionally to ensure even cooking. Add the 24 cherry tomatoes and the garlic confit (garlic cloves only, without the oil). Cook over high heat until the cipollini are golden brown, about 5 minutes. Add the 2 tablespoons of butter and season with salt and pepper. Stir until the butter is melted and coats the vegetables.
Assemble the Dish: To serve, transfer the grouper to a platter. Top with the finely chopped preserved lemons and drizzle with 1 tablespoon of olive oil. Spoon the roasted cipollini and tomatoes on top of the fish. Garnish with the cilantro and parsley.
Prepare the Preserved Lemons (at least 1 week prior): Wash the 8 lemons very well. Cut each lemon lengthwise into quarters without slicing all the way through, leaving the lemons whole but sectioned. Place the lemons in a sterilized jar. Add the 3 cups of coarse salt, 1 1/2 cups of lemon juice, 1 tablespoon of peppercorns, and 4 kaffir lime leaves. Mix well. Add more lemon juice if needed to just cover the lemons. Close with a lid and refrigerate. Stir the lemons every day or two to help dissolve the salt. Allow the lemons to cure for at least 1 week. Rinse under cold water before using. The longer they sit, the more mellow and complex their flavor becomes.

Expert Tips & Tricks

Garlic Confit Secret: Don’t rush the garlic confit! Cooking it low and slow is key to achieving that melt-in-your-mouth texture and preventing a bitter taste.
Perfectly Seared Skin: Ensure the grouper skin is completely dry before searing. Pat it down with paper towels for the crispiest results.
Oven Placement Matters: When baking the grouper, place the skillet in the middle rack of the oven for even cooking.
Make Ahead: The garlic confit and preserved lemons can be made well in advance, saving you time on the day of cooking.

Serving & Storage Suggestions

Serve the grilled grouper immediately for the best flavor and texture. The combination of the flaky fish, sweet roasted vegetables, and tangy preserved lemons is best enjoyed fresh.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, gently warm the fish in a skillet over low heat or in a low-temperature oven to prevent it from drying out. The roasted vegetables can be reheated in a skillet or microwave. Note that the texture of the fish may change slightly upon reheating. Freezing is not recommended as it can significantly alter the texture of the grouper.

Variations & Substitutions

Fish Variety: If you can’t find grouper, snapper, sea bass, or cod are excellent substitutes. Adjust cooking time slightly depending on the thickness of the fillet.
Herb Garden Swap: Feel free to experiment with other fresh herbs like oregano or marjoram in place of rosemary and thyme.
Spicy Kick: For extra heat, add a pinch of red pepper flakes to the roasted vegetables.
Vegetarian Option: Swap the grouper for grilled halloumi cheese or thick slices of eggplant for a vegetarian-friendly version.

FAQs (Frequently Asked Questions)

Q: Can I use regular lemons if I can’t find Kaffir lime leaves for the preserved lemons?
A: Yes, you can omit the kaffir lime leaves or substitute with a small piece of lime zest. The kaffir lime leaves add a unique citrus aroma, but the preserved lemons will still be delicious without them.

Q: How do I know when the grouper is cooked through?
A: The grouper is done when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C). Avoid overcooking, as this can make the fish dry.

Q: Can I grill the grouper entirely on the grill instead of searing and baking?
A: Absolutely! Adjust the grilling time accordingly, and be sure to monitor the internal temperature to prevent overcooking. Using a grilling basket can help prevent the fish from sticking.

Q: What’s the best way to store and use the garlic confit?
A: Store the garlic confit in an airtight container in the refrigerator, completely submerged in the oil. It will last for up to 2 weeks. Use the infused oil for salad dressings or as a flavorful finishing oil.

Q: Can I make the preserved lemons without salt?
A: Unfortunately, salt is crucial for the preservation process. It draws out moisture and inhibits bacterial growth. You cannot effectively preserve lemons without a significant amount of salt.
