Keto Garlic Butter Lobster Tails (Printable)

Tender lobster tails roasted with garlic butter and crisp asparagus for an elegant low-carb dinner ready in 30 minutes.

# Components:

→ Seafood

01 - 2 lobster tails (about 6 oz each), thawed if frozen

→ Vegetables

02 - 12 asparagus spears, trimmed

→ Fats & Oils

03 - 4 tablespoons unsalted butter, melted
04 - 1 tablespoon olive oil

→ Aromatics & Seasoning

05 - 3 garlic cloves, minced
06 - 1 tablespoon fresh parsley, chopped
07 - 1 teaspoon lemon zest
08 - 1 tablespoon fresh lemon juice
09 - 1/2 teaspoon smoked paprika
10 - 1/2 teaspoon sea salt
11 - 1/4 teaspoon black pepper

# Method:

01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - Using kitchen shears, cut down the top of each lobster shell lengthwise and gently pull the meat out, resting it on top of the shell.
03 - In a small mixing bowl, combine melted butter, olive oil, minced garlic, parsley, lemon zest, lemon juice, smoked paprika, salt, and black pepper. Whisk until well incorporated.
04 - Arrange lobster tails and asparagus spears on the prepared baking sheet. Brush both generously with the garlic butter mixture using a pastry brush.
05 - Roast in the oven for 12 to 15 minutes, until lobster meat is opaque and asparagus is tender-crisp.
06 - Transfer to serving plates and garnish with extra fresh parsley and lemon wedges if desired.

# Expert Advice:

01 -
  • Lobster feels indulgent, but at under 5 grams of carbs per serving, you're not cheating on keto at all.
  • The whole thing comes together in 30 minutes, which means you can impress someone on a weeknight without stress.
  • Asparagus soaks up that garlic butter like a sponge, so you get restaurant-quality side without thinking twice.
02 -
  • Don't cook the lobster shell-side down—if you flip it mid-way or leave it face-down, the meat dries out and loses that succulent sweetness that makes lobster worth eating.
  • If your lobster tails are especially thick, add 2–3 extra minutes to the roasting time; thinner ones cook fast and can turn rubbery if you're not paying attention.
03 -
  • Buy lobster tails from a good seafood counter where they move inventory quickly—fresh, sweet lobster makes a massive difference in the final dish.
  • If you're nervous about the cooking time, insert an instant-read thermometer into the thickest part of the meat; it should read 140°F for perfectly cooked lobster.
