Grilled Maine lobster tail is sweet, tender lobster cooked over high heat and finished with a quick garlic-lemon butter. Splitting the shell and loosening the meat helps it cook evenly while keeping it moist, and the grill adds a light smoky flavor without masking the lobster.
Ingredients
- 4 Maine lobster tails, 5–6 ounces each, thawed if frozen
- 4 tablespoons unsalted butter
- 1 medium garlic clove, finely minced
- 1 tablespoon fresh lemon juice, plus lemon wedges for serving
- 1 tablespoon chopped fresh parsley
- 1 tablespoon olive oil, for brushing the grill and lobster
- ½ teaspoon kosher salt, or to taste
- ¼ teaspoon freshly ground black pepper
- ⅛ teaspoon paprika, optional
Instructions
- Thaw and prepare the tails. If the lobster tails are frozen, thaw them overnight in the refrigerator, or place them in a sealed bag in cold water until thawed, changing the water every 30 minutes. Do not thaw them at room temperature. Pat the tails dry. With kitchen shears, cut lengthwise down the center of the hard top shell, from the open end toward the tail fan, stopping before cutting through the fan. Keep the soft underside intact. Use your fingers to loosen the meat from the shell, then lift it gently and rest it on top of the shell. Leave the tail end attached so the meat stays in place. This is often called butterflying the tail.
- Make the garlic butter. Melt the butter in a small saucepan over low heat. Stir in the minced garlic and cook for about 30 seconds, just until fragrant; do not let the garlic brown. Remove from the heat and stir in the lemon juice and parsley. Set aside about half for serving, keeping it separate from the brush used on raw lobster.
- Heat the grill. Preheat a gas or charcoal grill to medium-high, about 400–450°F. Clean the grates and lightly brush them with oil. If using charcoal, arrange the coals so you have a cooler area available in case the shells char before the meat is cooked through.
- Season the lobster. Brush the exposed meat lightly with olive oil. Season with salt, pepper, and paprika if using. Place the tails shell-side down on the grill. Close the lid and cook for 5 minutes.
- Baste and finish cooking. Brush the meat with garlic butter, then continue grilling shell-side down for about 3–6 minutes, depending on tail size and grill heat. Check early: smaller tails may be done sooner. The meat should turn opaque and firm, with a slight spring when pressed. For a reliable safety check, insert an instant-read thermometer into the thickest part of the meat without touching the shell; cook until it reaches 145°F. Avoid relying on shell color alone.
- Rest and serve. Transfer the tails to a clean plate and rest for 2 minutes. Serve with the reserved garlic butter and lemon wedges. Discard any butter or marinade that touched raw lobster; never serve it as the finishing sauce.
Tips
- Choose tails of similar size. Matching sizes make it easier for all four portions to finish at the same time. If one tail is larger, move it to a hotter spot or give it extra time, checking its temperature separately.
- Keep the heat controlled. A very hot grill can blacken the shell and scorch the garlic butter before the center cooks. If the meat browns too quickly, shift the tails to the cooler side and close the lid to finish gently.
- Use a thermometer rather than guessing. Lobster turns dry and chewy when overcooked. Begin checking the thickest tail early, and take each portion off the grill as soon as it reaches 145°F.
- Butterfly carefully. Cut only the hard top shell, not the meat or the thin underside. If the shell is difficult to cut, use sharp kitchen shears and keep the tail flat on a stable cutting board.
Serving Suggestions
Serve each tail hot with lemon wedges and a small dish of warm garlic butter. For a summery meal, pair the lobster with grilled corn, a crisp green salad, or sliced tomatoes. Roasted or grilled potatoes, rice pilaf, and crusty bread are satisfying options for soaking up the butter. For a lighter plate, add asparagus or green beans and keep the butter on the side so everyone can choose how much to use.
Variations
For a simple herb version, add chopped chives or tarragon to the butter with the parsley. To give the butter a gentle kick, add a pinch of cayenne or a few drops of hot sauce. You can replace the lemon juice with lime juice for a brighter, slightly different citrus flavor. If you prefer a more pronounced smoky note, use a small pinch of smoked paprika, but keep it modest so it does not overpower the lobster. For dairy-free cooking, brush the tails with olive oil and finish with lemon and herbs instead of butter.
Storage and Reheating
Refrigerate leftover cooked lobster within 2 hours of cooking, or within 1 hour if the surrounding temperature is above 90°F. Remove the meat from the shell and place it in an airtight container; store the garlic butter separately. Use refrigerated lobster within 3–4 days. For the best texture, reheat gently: place the meat in a covered dish with a teaspoon of water or butter and warm it in a 275°F oven until just heated through, checking frequently. You can also warm it briefly in a covered skillet over low heat. Avoid high heat and repeated reheating, which make lobster tough. Do not leave cooked lobster at room temperature for more than 2 hours, and discard it if it has been held longer or smells or looks questionable.
Frequently Asked Questions
Can I grill frozen lobster tails?
Thaw them completely before grilling. Even cooking is difficult when the center is frozen, and the outside may become tough before the meat is safely cooked. Thaw in the refrigerator or in a sealed bag submerged in cold water, then pat dry.
Should lobster tails be grilled shell-side up or down?
For this recipe, grill them shell-side down throughout. The shell acts as a protective barrier from direct heat, helping the meat cook more gently while you baste the exposed side.
How long does it take to grill a lobster tail?
For 5–6-ounce tails, plan on about 8–11 minutes total over medium-high heat, but treat that as an estimate. Grill temperature, tail thickness, and whether the tails started cold all affect timing. Verify that the thickest part reaches 145°F.
Can I make these without butter?
Yes. Brush the meat with olive oil and season with salt and pepper, then serve with lemon and chopped herbs. The lobster will still grill well, though it will not have the rich garlic-butter finish.
How can I tell when lobster is done without a thermometer?
The thickest part should be opaque rather than translucent and should feel firm but not hard. These signs are less dependable than temperature, so an instant-read thermometer is the best way to avoid both undercooking and overcooking.
Can I prepare the tails ahead of time?
You can thaw and butterfly them up to a day ahead. Keep the prepared raw tails covered in the refrigerator and grill them the day you serve them. Make the butter ahead too, then refrigerate it and rewarm gently; use a clean utensil for serving.
