Ingredients

For 2 servings of butter poached lobster tail:

• 2 lobster tails (6-8 oz/170-225g each), shell removed
• 8 oz (227g) unsalted butter, cut into small cubes
• 2 tablespoons (30ml) water
• 2 cloves garlic, smashed
• 1 small shallot, thinly sliced
• 2 sprigs fresh thyme
• 1 bay leaf
• 1 lemon, zested and juiced
• 1 tablespoon (15ml) white wine (optional)
• Salt, to taste
• Freshly ground black pepper, to taste
• 1 tablespoon (3g) fresh chives, finely chopped (for garnish)

The quality of butter is crucial for this recipe—opt for high-quality European-style butter with high butterfat content if possible. Fresh lobster tails will deliver the best flavor, though frozen (properly thawed) can work well too. The aromatics infuse the butter with complexity without overpowering the delicate lobster meat.

Pro Tips

Create the Perfect Beurre Monté: The foundation of successful butter poached lobster is the beurre monté (mounted butter), which is essentially an emulsion of butter and water. Start by heating the water until just below simmering (around 180°F/82°C), then gradually whisk in the cold cubed butter. The key is maintaining this temperature range—if the mixture gets too hot, the emulsion will break and separate into clarified butter and milk solids. Use a kitchen thermometer to monitor the temperature if possible.

Master the Lobster Preparation: Before poaching, properly prepare your lobster tails by using kitchen shears to cut through the top of the shell lengthwise, then carefully remove the meat in one piece. Leave the tail fan attached if possible for presentation. Remove the dark vein (digestive tract) that runs along the back. For even cooking, butterfly larger tails by making a shallow cut down the center without cutting all the way through.

Perfect the Poaching Technique: The most critical aspect of butter poached lobster tail is gentle, slow cooking. Never allow the butter mixture to boil or even simmer—it should remain between 160-180°F (71-82°C) throughout the entire cooking process. Depending on the size, lobster tails typically need 5-7 minutes to cook through. Watch for the meat to become opaque and reach an internal temperature of 140-145°F (60-63°C). Overcooking will cause the lobster to become tough and rubbery, so set a timer and check frequently.

Instructions

Step 1: Prepare the Lobster Tails

Using sharp kitchen shears, cut lengthwise through the top of each lobster shell, stopping at the tail fin. Carefully slide your fingers between the meat and shell to gently remove the lobster meat in one piece, keeping the tail fan attached for presentation. Check for and remove the dark intestinal vein running down the back. Rinse the lobster meat under cold water and pat thoroughly dry with paper towels. For even cooking, make a shallow cut (about ¼ inch deep) along the center of larger tails without cutting all the way through.

Step 2: Create the Beurre Monté

In a medium saucepan over medium-low heat, add 2 tablespoons of water and bring it to just below a simmer (around 180°F/82°C). Reduce the heat to low, then begin adding the cubed butter a few pieces at a time, whisking constantly to create an emulsion. Continue adding butter gradually, ensuring it’s fully incorporated before adding more. Never let the mixture boil—it should remain below 180°F to prevent separation. Once all butter is incorporated, add the smashed garlic, sliced shallot, thyme sprigs, bay leaf, lemon zest, and white wine (if using). Season with a pinch of salt and allow the aromatics to infuse the butter for 5 minutes over very low heat.

Step 3: Poach the Lobster

Ensure your butter mixture remains between 160-180°F (71-82°C)—use a kitchen thermometer for accuracy. Gently place the prepared lobster tails into the butter bath, making sure they’re fully submerged (add more butter if needed). Poach the lobster for 5-7 minutes, depending on size, occasionally basting with the butter. The meat should turn opaque and reach an internal temperature of 140-145°F (60-63°C). Be vigilant about maintaining the temperature—adjust your heat source as needed to keep the butter from getting too hot.

Step 4: Rest and Serve

Once cooked, carefully remove the lobster tails from the butter bath using a slotted spoon and transfer to a plate. Let them rest for 1-2 minutes. Strain a few tablespoons of the butter mixture through a fine-mesh sieve, discarding the aromatics. Add a squeeze of fresh lemon juice to the strained butter to create a quick sauce. Place the butter poached lobster tail on serving plates, drizzle with the lemon butter sauce, and sprinkle with fresh chives. Serve immediately while still warm, perhaps with additional melted butter on the side for dipping.

Variations

Herb-Infused Butter Poached Lobster: Enhance your butter poached lobster tails by expanding the aromatic profile. Add tarragon, dill, or chervil to the poaching liquid for distinctive herb notes that complement the sweetness of the lobster. You can also incorporate a splash of pastis or Pernod for an elegant anise undertone that pairs beautifully with seafood.

Spicy Butter Poached Lobster: For those who enjoy heat, create a Cajun-inspired version by adding crushed red pepper flakes, paprika, and a dash of cayenne to your butter poaching liquid. Finish with a sprinkle of Old Bay seasoning and serve with grilled corn and potatoes for a Southern-inspired feast that transforms the classic butter poached lobster tail into something with bold personality.

Asian-Inspired Butter Poached Lobster: Replace the traditional aromatics with ginger, lemongrass, lime leaves, and a splash of coconut milk for an Asian twist. After poaching, drizzle the lobster with a sauce made from the strained poaching butter, a splash of fish sauce, lime juice, and a touch of honey. This variation creates an unexpected but harmonious fusion that respects the delicate flavor of the lobster while introducing exciting new dimensions.

Storage and Serving

While butter poached lobster tail is best enjoyed immediately after cooking, leftovers can be stored in an airtight container in the refrigerator for up to 24 hours. To reheat, place the lobster in a heatproof bag with some of the reserved butter and submerge in warm (not hot) water for about 5-7 minutes until just warmed through. Avoid using the microwave, which will toughen the meat.

For an elegant presentation, serve your butter poached lobster tail atop a small pool of pureed cauliflower or potato for a stunning white-on-white presentation, garnished with microgreens and a sprinkle of caviar. Alternatively, pair with asparagus and saffron risotto for a classic fine-dining experience. For a more substantial meal, serve alongside a simple linguine tossed with the strained poaching butter, garlic, and a touch of parsley.

The reserved poaching butter can be strained and refrigerated for up to 3 days—it makes an incredible base for sauces or for sautéing vegetables to accompany other seafood dishes.

FAQs

Can I use frozen lobster tails for butter poaching?
Yes, but thaw them completely in the refrigerator overnight before cooking. Pat them thoroughly dry before poaching to ensure proper cooking and flavor absorption.

Why did my butter sauce separate?
The temperature likely got too high. Butter emulsions break above 180°F (82°C). If this happens, you can try to rescue it by removing from heat and whisking in 1-2 teaspoons of cold water until it re-emulsifies.

How can I tell when the lobster is perfectly cooked?
Properly cooked butter poached lobster tail will be opaque but still moist, with an internal temperature of 140-145°F (60-63°C). It should be firm yet tender when pressed gently with a fork.

Can I make butter poached lobster ahead of time for a dinner party?
It’s best prepared just before serving, but you can prepare the beurre monté in advance and reheat it gently. Then poach the lobster right before serving.

What’s the difference between butter poached and regular boiled lobster?
Butter poaching uses much lower temperatures and the fat content of the butter, resulting in significantly more tender meat with richer flavor compared to boiled lobster, which can become tough more easily.

Conclusion

This butter poached lobster tail is luxury dining at its finest — a silky, tender delicacy bathed in aromatic butter that transforms an already special ingredient into something truly extraordinary.
