You just picked up fresh Maine lobster tails from your local seafood purveyor or were lucky to receive a delivery to your door from LobsterAnywhere. Now, how do you prepare them for cooking? While there are several ways to prep tails, we’ll show you how and why we love butterfly lobster tails—the secret technique professional chefs use to achieve perfectly even cooking and stunning presentation.
Quick Method
- Cut the shell: Use kitchen shears to cut down the center of the TOP shell only, stopping at the fan tail.
- Slice the meat: Cut through the meat 3/4 of the way — don’t pierce the bottom shell.
- Open like a book: Spread the shell halves while keeping the bottom shell intact as the hinge.
- Clean and prepare: Remove the dark vein, rinse briefly under cold water, and pat completely dry.
Result: Evenly exposed meat that cooks faster and more evenly while the bottom shell acts as a tray. Optional: lift & tuck the meat for piggyback-style presentation.
Butterflying opens the tail like a book, exposing maximum surface area for seasonings while creating an elegant, restaurant-quality appearance. Unlike piggyback preparation, butterflying keeps the meat nestled in the shell while allowing heat to penetrate evenly from both sides. In this article, we’ll offer step-by-step instructions plus easy cooking recipes that will transform your lobster tails from ordinary to extraordinary in just 5 minutes of prep time.

What is Butterfly Cutting? (Why It’s Different from Piggyback)
Don’t be confused; butterflying tails are not the same as piggyback lobster tails. There are many recipe bloggers who write instructions incorrectly. The difference is that butterflying is when you open the tail up like a butterfly or book, while the piggyback prep pulls the meat up on the top of the shell. Both methods lend themselves to different cooking techniques. Below, we will outline how to cook a butterflied tail.
Why Butterfly vs Other Methods?
Butterflying advantages:
- Cooks 25% faster than whole tails
- Even heat distribution prevents overcooking
- Maximum surface area for seasonings
- Professional restaurant appearance
When NOT to butterfly:
- Boiling (meat gets waterlogged)
- Very small tails (under 4 oz)
- If serving whole lobster presentation
Butterfly vs Piggyback vs Whole:
| Method | Best For | Cook Time | Presentation |
|---|---|---|---|
| Butterfly | Grilling, baking, broiling | 8-12 min | Restaurant elegant |
| Piggyback | Baking, roasting | 6-10 min | Steakhouse dramatic |
| Whole | Boiling, steaming | 10-15 min | Classic traditional |
💡 Quick decision: New to lobster prep? Start with butterflying – it’s forgiving and always looks impressive.

Essential Tools for Butterflying Lobster Tails
Primary Cutting Tools:
- Heavy-duty kitchen shears – Look for stainless steel shears with serrated edges that can cut through tough lobster shells cleanly. The blades should stay sharp and have comfortable grip handles for safety.
- Sharp chef’s knife (8-10 inch) – A well-maintained chef’s knife is essential for cutting through lobster meat without tearing. The blade should be sharp enough to slice cleanly through the delicate meat.
- Small paring knife – Perfect for precision work like removing the dark intestinal vein and cleaning around shell edges.
Workspace & Safety Equipment:
- Large cutting board – Choose a board at least 12×18 inches to provide ample workspace. Wood or plastic boards both work well for seafood preparation.
- Kitchen towel – Essential for gripping slippery lobster shells safely and preventing accidents during cutting.
- Non-slip cutting board mat – Keeps your cutting board stable and secure during the butterflying process.
Temperature & Measurement Tools:
- Instant-read thermometer – Critical for ensuring lobster reaches the safe internal temperature of 140°F for perfect doneness.
- Kitchen scale – Helps determine accurate cooking times based on lobster tail weight.
Preparation Accessories:
- Paper towels – For patting tails dry and general cleanup during preparation.
- Small bowl – For collecting shell debris and removed veins during cleaning.
- Silicone basting brush – Ideal for applying melted butter, olive oil, or marinades to butterflied tails.
Optional Professional Tools:
- Seafood crackers – Useful backup for exceptionally thick or hard lobster shells.
- Seafood picks or tweezers – Helpful for removing small shell fragments or stubborn pieces of vein.

For those planning to prepare whole lobsters or wanting a comprehensive seafood toolkit, see our detailed guide on essential lobster tools covering everything needed for cracking and enjoying whole Maine lobsters.
Tool Selection Tips:
- Prioritize sharp, quality tools – Sharp blades are safer and create cleaner cuts through delicate lobster meat
- Choose stainless steel over plastic – Metal tools handle tough shells better and last longer
- Ensure proper tool maintenance – Keep knives sharp and shears clean for optimal performance
Safety Equipment Essentials:
- Always have a secure cutting surface with non-slip mats
- Keep kitchen towels handy for safe handling of slippery shells
- Maintain clean tools to prevent cross-contamination during seafood preparation
Choosing Tools by Lobster Tail Size:
- Small tails (4-6 oz): Use lighter pressure and consider kitchen scissors instead of heavy shears – the shells are thinner and more delicate
- Medium tails (6-10 oz): Standard technique works perfectly with regular kitchen shears
- Large tails (10+ oz): May require stronger shears; cut slowly with steady pressure to avoid cracking
- Colossal tails (16+ oz): Consider splitting completely instead of butterflying for easier handling
Pro tip: These same tools are excellent for other seafood preparation techniques like splitting lobster tails, preparing crab, or butterflying shrimp, making them versatile additions to any home kitchen.
Using proper technique is crucial – see our comprehensive lobster tail cutting guide for all preparation methods.
How to Butterfly Lobster Tails: Complete Step-by-Step Guide
Here are some simple steps to butterfly lobster tails at home.
-
Prepare Your Workspace Step 1
- Fully thaw lobster tails — ensure tails are completely defrosted (see our defrosting guide).
- Pat tails dry with paper towels to remove excess moisture and ice crystals.
- Gather your tools: kitchen shears, sharp chef’s knife, cutting board, and kitchen towel.
- Secure a cutting board with a non-slip mat or a damp towel underneath for stability.
- Position a kitchen towel nearby for gripping slippery shells safely.
-
Cut the Top Shell Only Step 2
- Position the tail shell-side up on the cutting board with the hard, curved shell facing you.
- Identify the center line — look for the natural ridge running down the middle of the shell.
- Using kitchen shears, cut down the center of the TOP shell only — start from the wide end and cut straight toward the fan tail.
- Stop at the fan tail — leave the fan completely intact (don’t cut through it).
- Important: Cut only through the hard top shell at this stage, not through any meat.
Safety Note: Always cut away from your body with controlled motions. Use the kitchen towel for a secure grip on slippery shells, and take your time — rushing leads to uneven cuts or accidents.
Visual check: You should have a straight cut down the top shell with the fan tail still attached and uncut.
-
Cut Through the Meat Carefully Step 3
Before cutting the meat: Ensure your knife is sharp for cleaner cuts through delicate lobster meat. Dull blades can tear the meat and are more dangerous to use.
- Insert your knife tip into the shell cut you just made at the wide end.
- Slice down through the lobster meat using steady, controlled pressure.
- Cut about 3/4 of the way deep — you want to cut most of the way through the meat, but not all the way.
- Critical: Stop before cutting through the bottom shell membrane — this acts as your “hinge.”
- Keep the knife blade angled slightly downward to avoid cutting through the bottom.
Visual check: The meat should be cut deep enough to open, but the bottom shell should remain completely intact.
-
Open Like a Book and Clean Step 4
- Gently spread the shell halves apart like opening a book — the bottom shell acts as the hinge.
- The meat should remain attached at the bottom while the top opens up.
- Rinse under cold running water to remove any shell debris or loose particles.
- Remove the dark intestinal vein if visible — use the tip of your knife to lift it out.
- Pat dry again with paper towels before seasoning or cooking.
Visual check: The tail should look like an open book with meat exposed on both sides but still connected at the bottom.
Final Check & Next Steps
Visual confirmation: Your butterflied lobster tail should lay flat like an open book, with the meat exposed for even cooking and easy seasoning. The bottom shell keeps everything connected while maximizing surface area for heat and flavor penetration.
Ready for cooking: Your butterflied tails are now perfect for grilling, broiling, or baking. See our complete lobster tail cooking guide for detailed cooking instructions and timing charts.
Time-saving tip: You can butterfly multiple tails at once using this same process – just work through each step systematically rather than completing one tail at a time.
Troubleshooting Common Butterfly Problems
| Problem | Quick Solution | Prevention |
|---|---|---|
| Shell cracks during cutting | Use sharp kitchen shears; make short, slow snips up the top shell. | Follow the center ridge; support the tail and cut only the top shell. |
| Can’t cut thick shells | Switch to heavy-duty seafood/poultry shears; score with knife tip, then snip. | Use serrated, rated shears; trim spines first for an easier path. |
| Bottom shell tears | Stop—don’t cut the underside. Open by pressing the sides, not bending the bottom. | Butterfly only the top shell; keep the underside intact as the “tray.” |
| Meat curls during cooking | Skewer lengthwise and cook shell-side down. | Skewer before cooking; use steady, moderate heat (avoid flare-ups). |
| Meat sticks to shell | Slide a finger under the meat to loosen before cooking; brief 30–60s ice bath after if needed. | Fully thaw and pat dry; baste under the meat; don’t overcook. |
| Uneven butterfly cut | Recenter with a shallow slit in the meat; lift and rest meat on the shell. | Mark a centerline; cut to (not through) the tail fan along the top shell. |
| Small shell fragments | Brush edges; remove spurs with a towel and inspect by touch. | Use controlled, short snips; avoid crushing the shell. |
| Visible vein or grit | Lift meat slightly and pull the vein; wipe away grit. | Always check and remove the vein after cutting, before seasoning. |
| Dry/rubbery texture | Baste and pull as soon as meat is opaque and just firm. | Cook by weight and method; verify doneness with an instant-read thermometer. |
Pro Tip: Even imperfect butterflying results in delicious lobster. Focus on complete thawing, sharp tools, and not overcooking rather than perfect presentation.

Grilling
Grilling is our favorite way to cook butterflied lobster tails. Unlike other methods, this allows the tail to spread flat on a grill. Set your grill at medium heat. Sear the meat side for a couple of minutes. Turn tails so the shell side is on the grill. Baste with butter or your favorite marinate. Cook for about 5 minutes, depending on the size of your tails. No need to flip. You do not want to lose the juices. Don’t have a grill? Grill on a cast iron pan on your stovetop. For more detailed cooking instructions, see our tips for grilling lobster tails. Check out our tips for grilling frozen lobster tails if you prefer grilling.
Roasting
Roasting cooks tails quickly at high heat. Preheat the oven to 425 degrees. Place the tails on a cookie sheet or roasting pan, shell side down. Brush with butter, olive oil, or your favorite spice rub. Roast for 6-8 minutes, depending on the size of the tail.
Steaming
Steaming cooks lobster tails with gentle, moist heat. Place butterflied lobster tails shell side down and steam for 5-6 minutes. See our complete guide for how to steam lobster tails at home.
Do you butterfly lobster tails before boiling?
Butterflying is usually done for grilling, broiling, or baking to add smoky flavor. It’s not needed for boiling because the exposed meat can get overcooked and lose its tenderness. If you are boiling lobster tails, you don’t need to butterfly them. Why butterfly lobster tails? Butterflying helps the meat cook evenly and lets flavors like butter or spices soak in better. It also makes the lobster look nice and appetizing.

Butterfly Lobster Tails FAQ
Do you butterfly lobster tails before or after thawing?
Always butterfly after thawing completely. Frozen tails are too hard to cut safely and you risk cracking the shell. Thaw overnight in the refrigerator, then pat dry before cutting.
Can you butterfly cooked lobster tails?
Not recommended. Cooked lobster meat tears easily and the shell becomes brittle. Always butterfly raw tails, then cook them for best results.
What’s the difference between butterfly and spatchcock?
Butterfly is for lobster tails – cutting the top shell to open like a book while keeping the bottom intact. Spatchcock is a poultry technique for flattening whole birds by removing the backbone.
How do you prevent butterfly lobster tails from curling?
Score the meat with 2-3 shallow crosswise cuts before cooking, or insert a wooden skewer lengthwise. Cook shell-side down using moderate heat and don’t overcook.
Do you butterfly lobster tails for boiling?
No. Butterflying is for grilling, broiling, and baking. For boiling, keep tails whole to prevent the meat from getting tough and waterlogged.
