Grilling lobster is often seen as a daunting task reserved for high-end steakhouse chefs, but it is actually one of the most rewarding ways to prepare this luxury crustacean at home. While steaming and boiling are traditional, the intense, smoky heat of a barbecue creates a unique depth of flavor that water-based methods simply cannot replicate. The high heat caramelizes the proteins in the meat and toasts the shell, imparting a nutty aroma that elevates the sweet, succulent flesh to a whole new level.
If you are looking to impress guests at your next backyard cookout or simply want to treat yourself to a gourmet meal, mastering the grill is the way to go. This guide will walk you through everything from selecting the right lobster to the final buttery bite.
Choosing the Best Lobster for Your Grill
Before you even light the coals, you need to ensure you have the right starting material. Not all lobsters are created equal when it comes to the heat of the grill.
Hard Shell vs. Soft Shell
Lobsters go through a molting process where they shed their old shells. “New shell” or soft-shell lobsters are often sweeter and easier to crack, but their meat is more delicate and contains more water. For the BBQ, hard-shell lobsters are generally preferred. Their shells act as a sturdier “boat” for the meat, protecting it from the direct flames and holding in the juices and flavored butters you’ll be adding later.
Sizing It Up
For individual servings, lobsters weighing between 1.25 and 1.5 pounds are ideal. They cook quickly and evenly without the risk of the exterior becoming rubbery before the center is done. If you are grilling just the tails, look for 6 to 8-ounce tails, as these provide a substantial portion that stands up well to high heat.
Essential Tools and Ingredients
Preparation is key when working with seafood on the grill. Because lobster cooks fast, you won’t have time to hunt for a pair of tongs once the shells hit the grates.
The Toolkit
- A sharp chef’s knife or heavy-duty kitchen shears.
- Long-handled grill tongs.
- An instant-read meat thermometer.
- A small saucepan for melting butter.
- A basting brush (silicone works best for high heat).
The Flavor Profile
While the lobster is the star, the aromatics you choose will define the dish. A classic garlic herb butter is the gold standard. You will need:
- Unsalted butter.
- Fresh minced garlic.
- Lemon juice and zest.
- Fresh herbs like parsley, chives, or tarragon.
- A pinch of smoked paprika or cayenne pepper for a subtle kick.
Preparing the Lobster for the Grate
There are two primary ways to prep a whole lobster for the grill: splitting it down the middle or “butterflying” the tails. Splitting the lobster entirely is the most common method for BBQ as it allows the heat to penetrate the meat directly while the shell protects the underside.
The Humane Approach
Most chefs recommend placing the lobster in the freezer for 15 to 20 minutes before preparation. This numbs the lobster and makes the process more ethical. Once chilled, place the lobster on a sturdy cutting board. Insert the tip of a sharp knife into the cross-mark on the back of the head and press down firmly to the board, then split the body and tail lengthwise.
Cleaning and Pre-Seasoning
Once split, remove the grain sac from the head and the long dark intestinal vein from the tail. You can leave the green “tomalley” (the liver) if you enjoy it, though many prefer to rinse it away for a cleaner presentation. Pat the meat dry with paper towels. Moisture is the enemy of a good sear; you want the butter to stick to the meat, not slide off on a layer of steam. Brush the meat generously with olive oil or melted butter and season lightly with sea salt.
Master the Grilling Technique
The secret to a perfect grilled lobster is a two-zone fire. You want a hot side for searing and a cooler side for gentle finishing.
Setting the Temperature
Preheat your grill to medium-high heat, aiming for an internal grill temperature of approximately 400°F to 450°F. Ensure the grates are scrubbed clean and lightly oiled to prevent sticking.
The Initial Sear
Place the lobster halves on the grill, meat-side down, over direct heat. This initial sear should only last about 2 to 3 minutes. This step is crucial for developing color and a hint of charred flavor. Watch for flare-ups, as the butter or oil can drip onto the coals.
The Flip and Baste
Carefully flip the lobsters so they are shell-side down. Move them to the cooler side of the grill (indirect heat) if the shells are browning too quickly. Now is the time to be generous with your herb butter. Use your brush to pool the butter into the crevices of the tail and body. Close the grill lid to create an oven-like environment, which helps the heat penetrate the thickest part of the tail.
Knowing When It Is Done
Overcooked lobster becomes tough and “rubbery,” losing its signature sweetness. The meat should be opaque and white, not translucent.
The Temperature Check
The most reliable way to ensure perfection is using an instant-read thermometer. Insert it into the thickest part of the tail meat. You are looking for an internal temperature of 140°F. Once it hits this mark, remove it immediately; carry-over cooking will bring it up to the ideal 145°F as it rests.
Visual Cues
If you don’t have a thermometer, look at the shell and the meat. The shell should be a vibrant, bright red across the entire body. The meat should feel firm to the touch and should have pulled away slightly from the sides of the shell.
Serving Suggestions
Once the lobster comes off the grill, let it rest for 3 to 5 minutes. This allows the juices to redistribute so they don’t all run out the moment you take a bite. Serve the lobster halves with extra charred lemon halves—grilling the lemons makes them sweeter and easier to squeeze.
Pair your BBQ lobster with simple sides that won’t overshadow the main event. Grilled corn on the cob, a crisp green salad, or a light potato salad with vinaigrette are excellent choices. A cold glass of Chardonnay or a crisp Sauvignon Blanc provides the perfect acidity to cut through the richness of the butter.
Frequently Asked Questions
-
Do I need to parboil the lobster before grilling?
While some people prefer to parboil the lobster for 2 to 3 minutes to ensure the meat stays tender, it is not strictly necessary. If you grill over indirect heat and use a meat thermometer, you can achieve perfect results starting from a raw state, which preserves more of the lobster’s natural juices.
-
Can I grill frozen lobster tails?
Yes, you can grill frozen tails, but they must be completely thawed first. Thaw them overnight in the refrigerator or in a sealed bag under cold running water. Grilling frozen meat will result in uneven cooking and a tough texture.
-
How do I prevent the lobster tails from curling on the grill?
To keep lobster tails straight for a better presentation, you can insert a wooden or metal skewer lengthwise through the meat before placing them on the grill. This prevents the muscle from contracting and curling as it hits the heat.
-
What should I do with the claws while grilling?
The claws take longer to cook than the tails because the shell is thicker. Many people prefer to crack the claws slightly before putting them on the grill to allow heat to enter, or they remove the claws and start grilling them 4 to 5 minutes before the tails.
-
Can I use a gas grill instead of charcoal?
Absolutely. While charcoal provides a traditional smoky flavor, a gas grill offers better temperature control. Simply follow the same two-zone cooking method by turning off one or two burners to create an indirect heating area.
