Ingredients Overview

Here’s what you’ll need for this flavor-packed dinner:

For the Lobster Tails:

  • 2 lobster tails (5–6 oz each)
  • 2 tbsp melted butter
  • 1 tsp Cajun seasoning
  • ½ tsp garlic powder
  • ½ tsp paprika
  • Fresh lemon wedge (for finishing)

For the Cajun Alfredo Pasta:

  • 8 oz pappardelle or fettuccine
  • 2 tbsp butter
  • 4 cloves garlic, minced
  • 1 ½ cups heavy cream
  • ¾ cup grated Parmesan cheese
  • 1 tsp Cajun seasoning (adjust to taste)
  • ½ tsp paprika
  • Salt & pepper to taste
  • Optional: ½ cup cooked chicken or shrimp

For the Garlic Butter Asparagus:

  • 1 bunch asparagus, trimmed
  • 1 tbsp olive oil
  • 1 tbsp butter
  • 2 cloves garlic, minced
  • Salt, pepper, and red pepper flakes to taste

Kitchen Equipment Needed

  • Kitchen shears (to butterfly the lobster tails)
  • Baking tray
  • Medium and large skillets
  • Large pot for boiling pasta
  • Tongs or spatula
  • Sharp knife and cutting board
  • Microplane or cheese grater (for Parmesan)
  • Citrus juicer (optional, for lemon)

Step-by-Step Instructions

1. Prep the Lobster Tails

Use kitchen shears to cut down the center of each shell lengthwise. Gently lift the lobster meat on top of the shell, leaving it attached at the base. This allows for even cooking and a beautiful presentation.

Brush the meat with melted butter, then sprinkle with Cajun seasoning, garlic powder, and paprika.

2. Bake or Broil

Preheat your oven to 400°F (or set broiler on high if using that method). Place the seasoned lobster tails on a baking sheet and cook for:

  • Bake: 10–12 minutes
  • Broil: 7–9 minutes

The meat should be opaque, tender, and slightly charred. Finish with a squeeze of fresh lemon juice to brighten the flavors.

3. Make the Cajun Alfredo

While the lobster bakes, boil your pasta in salted water according to the package instructions. Drain and set aside.

In a skillet over medium heat, melt 2 tablespoons of butter. Add minced garlic and sauté for about 1 minute until fragrant. Pour in the heavy cream and let it simmer for 3–5 minutes.

Stir in the Parmesan, Cajun seasoning, paprika, salt, and pepper. Allow the sauce to thicken slightly before tossing in the cooked pasta.

Optional: Add cooked shrimp or chicken here for extra protein.

4. Sauté the Asparagus

In a separate skillet, heat olive oil and butter over medium heat. Add garlic and asparagus and cook for 5–7 minutes, stirring occasionally, until the asparagus is tender but still crisp.

Season with salt, pepper, and a pinch of red pepper flakes for a touch of heat.

5. Plate It Up

Twirl the creamy Cajun Alfredo pasta onto plates or shallow bowls. Gently place a lobster tail on top of the pasta, and serve with a side of garlic butter asparagus. Garnish with chopped parsley or a light dusting of extra Cajun seasoning.

Recipe Tips & Variations

  • Lobster Substitutes: If lobster tails aren’t available, try large shrimp or even seared scallops.
  • Spice Level: Cajun seasoning blends vary—start with less and add to taste.
  • Cheese Swap: Swap Parmesan for Pecorino Romano for a sharper bite.
  • Low-Carb Option: Use spiralized zucchini or cauliflower mash instead of pasta.
  • Make It Ahead: Prepare the Alfredo sauce in advance and reheat gently on the stovetop.

How to Store & Reheat Leftovers

Storage: Store leftovers in airtight containers. The lobster and pasta can be refrigerated for up to 2 days.

Reheat Tips:

  • Reheat the Alfredo pasta in a skillet over low heat with a splash of cream or milk to loosen the sauce.
  • Warm lobster tails in the oven at 300°F for 5–7 minutes, wrapped in foil to avoid drying out.
  • Asparagus can be reheated in a skillet or the microwave, though it’s best fresh.

Perfect Pairings

To complete your gourmet dining experience, pair this dish with:

  • Wine: A buttery Chardonnay or crisp Sauvignon Blanc
  • Bread: Warm crusty garlic bread or a side of herbed focaccia
  • Salad: A fresh arugula salad with lemon vinaigrette
  • Dessert: Something light and citrusy like lemon sorbet or a berry tart

Frequently Asked Questions (FAQ)

Can I use frozen lobster tails?
Yes! Just thaw them completely in the refrigerator overnight or under cold water for 30–60 minutes before preparing.

How do I know when lobster is fully cooked?
Lobster meat turns opaque and white when done. It should be firm but not rubbery. A good rule: the internal temp should be around 140°F.

Can I use jarred Alfredo sauce?
You can, but the homemade version is much richer and more flavorful. If using jarred sauce, jazz it up with garlic, Cajun seasoning, and Parmesan.

Is this recipe spicy?
It has a mild to medium heat depending on your Cajun seasoning. Adjust to taste or omit red pepper flakes if you’re spice-sensitive.

What other veggies can I use instead of asparagus?
Try sautéed broccolini, roasted Brussels sprouts, or green beans for a similar vibe.
