Grilled Cowboy Butter Lobster Tails – Bold, Buttery, and Perfect for the Grill
Ingredients
Method
- Prep the grill: Heat a gas or charcoal grill to medium-high, about 425–450°F.Clean and oil the grates to prevent sticking.
- Make the cowboy butter: In a bowl, mash the softened butter with garlic, Dijon, lemon juice and zest, parsley, chives, thyme, smoked paprika, red pepper flakes, cayenne (if using), salt, and pepper. Mix until smooth. Reserve 2 tablespoons for serving and keep the rest ready for basting.
- Butterfly the lobster tails: Using kitchen shears, cut the top of the shell down the center to the tail fan.Gently loosen the meat from the shell, lift it out, and rest it on top of the shell, keeping it attached at the tail. This helps it cook evenly and look great.
- Season the meat: Pat the lobster dry. Brush with olive oil and season lightly with salt and pepper.
- Grill shell-side down first: Place the tails on the grill, shell-side down.Close the lid and cook for 4–5 minutes until the meat starts turning opaque around the edges.
- Baste generously: Spoon or brush a layer of cowboy butter over the exposed lobster meat. Close the lid and cook 2–3 more minutes. The butter will melt into the meat and drip into the shell, basting from underneath too.
- Optional flip: For a light char, flip meat-side down for 20–30 seconds.Don’t overdo it—this is just to kiss it with flame.
- Check doneness: The lobster is ready when the meat is opaque and firm, not translucent. Internal temp should be 135–140°F in the thickest part.
- Finish and serve: Transfer to a platter. Top with the reserved cowboy butter and a squeeze of fresh lemon.Serve hot.
Why This Recipe Works
- High heat + shell-on grilling locks in moisture while adding a subtle char and smoke.
- Cowboy butter is a flavor bomb: tangy, herby, garlicky, and slightly spicy, which balances the natural sweetness of lobster.
- Butterflied tails cook evenly and present beautifully, making basting easier and more effective.
- Fast cook time keeps the lobster tender, not rubbery, and the butter does the rest.

How to Store
- Refrigerate: Store cooled cooked lobster in an airtight container for up to 2 days. Keep extra cowboy butter covered in the fridge for up to 1 week.
- Reheat gently: Warm lobster in a covered skillet over low heat with a dab of butter or a splash of water, 2–3 minutes. Avoid the microwave; it can make the meat rubbery.
- Freeze: Cooked lobster can be frozen up to 2 months.Wrap tightly and thaw overnight in the fridge. Cowboy butter freezes well too—roll in parchment and freeze up to 3 months.
Benefits of This Recipe

- High-impact flavor: Cowboy butter transforms simple grilled seafood into a steakhouse-style dish.
- Flexible heat level: You control the spice, from mild to bold.
- Great for entertaining: Easy to scale and looks stunning on a platter.

Common Mistakes to Avoid
- Overcooking: Lobster goes from tender to tough quickly. Keep a close eye and use a thermometer if you can.
- Skipping the butterfly step: Whole shells trap steam and can lead to uneven cooking.Butterflying ensures consistent results.
- Not drying the meat: Excess moisture prevents the butter from clinging and dilutes flavor.
- Underseasoning: Lobster is delicate; a little salt and the right butter balance make a big difference.
- Grill too cool or dirty grates: You want medium-high heat and clean, oiled grates for good texture and easy release.
Recipe Variations
- Lemon-pepper cowboy butter: Add extra lemon zest and swap smoked paprika for cracked black pepper.
- Herb-forward: Double the parsley and chives and add tarragon for a fresher, lighter profile.
- Garlic-parmesan twist: Stir 2 tablespoons finely grated Parmesan into the butter for a savory edge.
- Chili-lime: Replace lemon with lime and use chipotle powder instead of paprika for a smoky-spicy finish.
- Surf and turf platter: Grill steak alongside and use the same cowboy butter for both.
- Oven broiler option: If you don’t have a grill, broil the butterflied tails 5–7 inches from the heat for 6–8 minutes, basting halfway.
FAQ
How do I choose good lobster tails?
Look for firm, translucent raw meat with no off smell. The shells should be intact and not slimy. Cold-water lobster tails (often from Maine or Canada) tend to be sweeter, but warm-water tails can be great too if fresh.
Can I use clarified butter instead?
Yes.
Clarified butter handles high heat better and won’t burn as easily. For flavor, still mix in the aromatics and seasonings from the cowboy butter.
Do I need to remove the vein?
Sometimes there’s a dark vein along the back of the meat. If you see it, gently pull it out with the tip of a knife.
It’s harmless but can be gritty.
What sides go well with this?
Grilled corn, roasted potatoes, a crisp green salad, garlic bread, or asparagus pair nicely. Keep sides simple and let the lobster and butter shine.
Can I prepare the butter ahead of time?
Absolutely. Make the cowboy butter up to 3 days in advance and keep it chilled.
Let it soften slightly before basting so it spreads easily.
How many lobster tails per person?
Plan on one 6–7 ounce tail per person for a main course, or two smaller tails if you want a generous portion. For surf and turf, one smaller tail per person works well.
What if I don’t have fresh herbs?
Use dried: 1 teaspoon dried parsley, 1/2 teaspoon dried chives, and 1/2 teaspoon dried thyme. The flavor will be a bit more concentrated, so taste and adjust salt and lemon.
Can I cook these on a stovetop?
Yes.
Use a grill pan or a cast-iron skillet over medium-high heat. Sear shell-side down first, baste, then finish under a broiler for 1–2 minutes if needed.
In Conclusion
Grilled Cowboy Butter Lobster Tails bring bold flavor and easy technique together in one standout dish. With a quick butterfly, a hot grill, and a generous brush of zesty, herby butter, you’ll get juicy, tender lobster every time.
