• 1 pound cavatappi or elbow pasta
• 1 pound cooked lobster meat, chopped
• 4 tablespoons butter
• 1/4 cup all-purpose flour
• 3 cups whole milk
• 1 cup heavy cream

Cheese blend

Shred 4 cups total from blocks. Room temperature melts better.

• 1 cup sharp white cheddar (sharpness)
• 1/2 cup Parmesan (saltiness)
• 1/2 cup cream cheese (extra creaminess)

Seasonings

• 1 teaspoon Dijon mustard
• 1/4 teaspoon cayenne pepper
• 1/4 teaspoon nutmeg
• 1/2 teaspoon garlic powder
• Salt and black pepper to taste

Topping

• 1 cup panko breadcrumbs
• 2 tablespoons melted butter
• 1/4 cup grated Parmesan

Equipment

• Large pot for pasta
• Medium saucepan for sauce
• 9x13 inch baking dish
• Whisk for smooth sauce

Lobster selection

Buy 2 small live lobsters (1.5 pounds each). Steam 8-10 minutes. Or buy 1 pound pre-cooked meat. Frozen lobster tails work. Thaw overnight. Pat completely dry. Excess water ruins sauce.

Pasta notes

Choose ridged pasta. Cavatappi, shells, or elbows trap sauce best. Cook 2 minutes less than package directs. Reserve 1 cup pasta water. Use to thin sauce if needed.

Cheese tips

Cheese quality determines creaminess. Avoid pre-shredded cheese. Contains cellulose. Prevents smooth melting. Shred from blocks. Gruyère gives nutty depth. Cheddar provides sharpness. Parmesan adds salty kick.

Cook pasta and prepare lobster meat

Cook the pasta

Fill large pot with 4 quarts water.

Add 2 tablespoons kosher salt.

Bring to rolling boil.

Pour in 1 pound cavatappi or elbow pasta.

Set timer for 2 minutes less than package directions.

Stir occasionally to prevent sticking.

Scoop out 1 cup pasta water before draining.

Drain pasta in colander.

Shake colander to remove excess water.

Rinse briefly with cold water to stop cooking.

Toss with teaspoon of olive oil.

Spread on baking sheet to cool.

Set aside.

Prep fresh lobster

Fill large pot with 2 inches water.

Add 1 tablespoon salt.

Bring to rapid boil.

Place live lobsters headfirst into pot.

Cover immediately with tight lid.

Steam 8-10 minutes for 1.5-pound lobsters.

Shells turn bright red when done.

Transfer lobsters to ice bath.

Let cool 5 minutes.

Twist off claws and tail sections.

Use lobster crackers on claws.

Cut tail shell lengthwise with kitchen shears.

Extract all meat in one piece.

Check for shell fragments.

Remove cartilage and vein.

Chop meat into 1-inch chunks.

Pat completely dry with paper towels.

Water ruins sauce texture.

Use pre-cooked lobster

Buy 1 pound cooked lobster meat.

Many seafood counters sell fresh cooked.

Or thaw frozen lobster tails overnight in fridge.

Do not microwave to thaw.

Remove meat from shells.

Chop into uniform 1-inch pieces.

Place on paper towel-lined plate.

Press gently with more paper towels.

Remove every drop of moisture.

Set aside at room temperature.

Prep timing strategy

Start pasta water boiling first.

Begin lobster while pasta cooks.

Both finish within 15 minutes.

If lobster finishes early, keep warm.

Set oven to lowest setting (200°F).

Place lobster on oven-safe plate.

Cover loosely with foil.

Hold up to 20 minutes.

Never refrigerate cooked lobster.

Cold lobster toughens when reheated.

Make rich, velvety cheese sauce

Melt 4 tablespoons butter in heavy saucepan over medium heat.

Add 1/4 cup flour when butter foams.

Whisk constantly 2 minutes.

Cook until nutty aroma develops.

Keep color pale. Brown roux overpowers cheese.

Add dairy slowly

Warm milk and cream in separate pot to 180°F.

Add to roux 1 cup at a time.

Whisk vigorously after each addition.

Scrape pan edges completely.

Bring to gentle simmer.

Cook 5-7 minutes until thick.

Coats spoon when ready.

Melt cheese properly

Remove from heat completely.

Let cool 30 seconds.

Add cream cheese first. Whisk smooth.

Add Gruyère handful by handful.

Whisk each addition completely before adding more.

Follow with cheddar, then Parmesan.

Never boil after adding cheese.

Keep temp below 180°F.

Season sauce

Stir in Dijon, cayenne, nutmeg, garlic powder.

Add salt and pepper.

Taste carefully.

Adjust as needed.

Pour hot cheese sauce over pasta.

Add chopped lobster meat.

Fold together with rubber spatula.

Work fast before sauce cools.

Coat every piece thoroughly.

Bake uncovered 25-30 minutes.

Watch crust turn golden brown.

Edges bubble vigorously when done.

Center should jiggle slightly.

Internal temperature reaches 165°F.

Cheese peeks through topping in spots.

If browning too fast, cover loosely with foil.

Remove foil last 5 minutes for final crisping.

Rest before serving

Remove from oven carefully.

Place on wire rack.

Do not refrigerate before serving.

Serve immediately with fresh herbs

Best herb choices

• Chives (snipped 1/4 inch pieces)
• Parsley (flat-leaf, chopped fine)
• Tarragon (small amount, strong flavor)
• Chervil (delicate, anise notes)

Scatter herbs over top right before serving.

Heat releases herb oils. Brightens rich dish.

Portion size guide

Storage and reheating

Refrigerate leftovers within 2 hours.

Microwave makes rubbery lobster. Avoid.

Add splash of milk before reheating. Restores creaminess.

Common serving mistakes

Skip the rest period. Sauce runs everywhere.

Let sit too long. Topping softens.

Forget herbs. Looks plain, tastes heavy.

Use cold plates. Food cools too fast.

Over-portion. Rich dish fills quickly.
