The Quick Take
Butterfly the lobster tails so the meat rests on top of the shell, then brush generously with garlic herb butter. Grill the tails meat-side down for 4 to 5 minutes over medium-high heat to develop a caramelized crust. Flip them shell-side down, baste with more butter, and grill for another 3 to 5 minutes. The lobster is fully cooked when the meat turns opaque white and registers exactly 140°F on a meat thermometer.

Setting Up for Success
Before any lobster hits the heat, you have to master the butterfly technique. Butterflying involves cutting the top of the shell and lifting the meat up so it rests elegantly on top. This not only makes for a stunning presentation, but it also allows the meat to cook evenly and absorb all that rich, smoky flavor from the fire.
You will want a grill setup that offers distinct heat zones. If you are using an Arteflame grill, the prep is incredibly simple: pour a little vegetable oil on three paper napkins, place them in the center of the grill, stack your firewood over the napkins, and light the paper. You will be ready to cook in about 20 minutes.
Because the Arteflame features a flat solid-steel cooktop that naturally creates heat zones, you can sear the lobster meat near the hot center edge, then slide it outward to a cooler zone to finish cooking gently without burning the delicate shell.
Step-by-Step Instructions
- Butterfly the tails: Using heavy-duty kitchen shears, cut straight down the middle of the top shell, stopping just before the tail fin. Gently pry the shell halves open and lift the meat out, resting it on top of the closed shell.
- Prevent curling: Run a wooden or metal skewer lengthwise through the center of the meat. This keeps the tail perfectly straight while it cooks.
- Season and baste: Brush the exposed meat generously with melted butter, minced garlic, a pinch of salt, and a squeeze of fresh lemon juice.
- Grill meat-side down: Place the lobster tails meat-side down on the 400°F zone of your cooktop. Grill for 4 to 5 minutes until the meat develops a beautiful, slightly charred crust.
- Flip and finish: Flip the tails so the shell is touching the cooktop. Baste the meat with more butter and let it cook for another 3 to 5 minutes.
- Check the temperature: Remove the lobster from the grill the exact second the internal temperature hits 140°F. The meat should be completely opaque.
Pro Tip: Always use clarified butter or ghee when basting lobster on a hot grill. Regular butter contains milk solids that will burn and turn bitter at high temperatures, ruining the delicate flavor of the seafood.
Common Mistakes to Avoid
- Guessing the temperature: Overcooked lobster has the texture of a bouncing tire. Don't guess. Invest in a high-quality instant-read thermometer from a brand like ThermoWorks and pull the meat at exactly 140°F.
- Mangling the shell with a dull knife: Trying to butterfly a tough lobster shell with a standard chef's knife is a recipe for disaster and potential stitches. Use proper, heavy-duty kitchen shears, like those from OXO, to make a clean, safe cut.
- Losing your butter to the fire gods: On a traditional open grate, melting butter just drips through, creating massive flare-ups and soot. Cooking on a flat steel cooktop means the butter pools beautifully under the lobster, basting it rather than burning it.
- Skipping the skewer: If you don't skewer the tails, they will curl up tightly the moment they hit the heat, making them cook unevenly and look a bit like sad, buttery armadillos.
Make It Your Own
Once you have the basic technique down, lobster tails are a blank canvas for incredible flavor profiles. Try these simple variations to mix things up:
- Spicy Cajun: Dust the meat with a heavy pinch of blackened seasoning and serve with a side of spicy remoulade.
- Citrus Tarragon: Mix fresh chopped tarragon and orange zest into your basting butter for a bright, aromatic twist.
- Smoked Paprika and Garlic: Add a teaspoon of high-quality smoked paprika to your clarified butter to double down on that rich, wood-fired flavor.
- Herb Crust: Top the butterflied meat with a mixture of panko breadcrumbs, parmesan, and parsley just before flipping to shell-side down.
Frequently Asked Questions
Do I need to boil lobster tails before grilling?
Absolutely not. Boiling lobster tails before grilling will overcook the meat and wash away its natural, sweet flavor. Grilling from raw allows the meat to caramelize and absorb the smoky essence of the fire.
Should I use fresh or frozen lobster tails?
Either works perfectly, but if you are using frozen tails, they must be completely thawed before they hit the grill. Thaw them slowly in the refrigerator overnight to preserve the texture of the meat.
How do I clean up after grilling seafood?
If you are cooking on an Arteflame, cleanup is a breeze. While the cooktop is still warm, simply scrape any leftover butter or seafood residue directly into the center fire. Give the steel a quick wipe with a cloth and a thin coat of cooking oil, and you are ready for your next cookout.
Keep the Fire Going
There you have it. You are no longer just a person with a spatula; you are a live-fire seafood artist. Mastering how to grill lobster tails guarantees you will be the absolute hero of the weekend, and it might just be the one dish impressive enough to keep your in-laws from offering unsolicited grilling advice. Enjoy the incredibly rich, smoky flavor that only an open fire can provide, and remember to savor that first buttery bite.
