The shrimp and lobster make it feel like a true special occasion while still totally doable for a home cook I first made it when my husband surprised me with fresh seafood and now it is my most requested birthday dinner

Ingredients

  • Elbow macaroni: Gives you those little pockets to catch all the cheesy sauce Choose a sturdy brand that holds its shape well when baked
  • Butter: Adds richness to both the cheese sauce and the sautéed seafood Use unsalted if you want flexibility with your seasoning
  • Olive oil: Keeps the seafood extra tender and flavorful Pick a fruity olive oil if you have it
  • Shrimp: Sweet meaty bites Pair fresh or thawed peeled shrimp for best texture
  • Cooked lobster meat: The star Use tail or claw meat Sniff for sweetness stay away from anything fishy smelling
  • Flour: Classic thickener for the cheese sauce All purpose is perfect
  • Milk: Provides creaminess without making it too heavy Whole milk builds body
  • Heavy cream: Makes everything luscious
  • Sharp cheddar cheese: Brings that cheesy punch Grate your own for the smoothest melt
  • Mozzarella cheese: Stretchy and gooey quality mozzarella makes a difference
  • Parmesan cheese: Adds saltiness and nutty flavor Shred fresh if possible
  • Salt and black pepper: Needed to balance all that creaminess
  • Paprika: Gives a smoky little hint and great color Use sweet paprika to avoid heat
  • Fresh parsley: Brightens up the whole dish Italian flat leaf is most flavorful
  • Optional Hawaiian rolls or brioche for serving: Soaks up all that sauce

Instructions

Boil the Macaroni:
Cook pasta in well salted boiling water until just al dente Check after 7 or 8 minutes then drain and set aside This makes a sturdy base for the cheese sauce and avoids mushy noodles
Sauté the Seafood:
In a wide skillet warm butter and olive oil over medium heat Add shrimp and cook for about three minutes just until they turn pink and curl Do not overcook or they will become tough Stir in the lobster meat just to warm it through and immediately transfer both to a clean plate to prevent overcooking This keeps the seafood perfectly tender and juicy for folding into the pasta
Make the Cheese Sauce:
In your main pot melt butter over medium heat Add flour and whisk constantly for about two minutes until the flour soaks up the butter and turns pale golden You are making a smooth roux for thickening Slowly pour in milk and heavy cream whisking as you go to avoid lumps Continue to cook while stirring often until the liquid thickens slightly about four minutes Turn heat to low and add shredded cheddar mozzarella and parmesan Stir until everything is silky and smooth The sauce should coat the back of a spoon Season with salt black pepper and paprika tasting as you go so the flavors shine
Combine and Bake:
Dump the cooked pasta and seafood gently into the cheese sauce and fold with a big spoon until every noodle is coated with cheesy richness Transfer everything into a large baking dish sprinkle generously with extra cheese and bake in a 375 degree oven for about twenty to twenty five minutes You are looking for bubbling edges and a golden brown cheesy top That is when the magic happens
Serve and Garnish:
Spoon generous portions onto plates Top with lots of fresh chopped parsley for a pop of color and bright flavor If you want go all out by serving with warmed Hawaiian rolls or buttery brioche for perfect sauce mopping

Shrimp is my all time favorite because it cooks in just a couple minutes and soaks up that cheese sauce I have so many memories of making this for my brother who claims this is the best mac he has eaten in his life

Storage Tips

Let any leftovers cool completely and then store them in tightly covered containers in the fridge for up to three days For longer storage portion out single servings into freezer safe containers The seafood stays surprisingly tender after reheating from chilled or frozen To reheat set the oven to 325 and cover the mac with foil to keep it from drying out

Ingredient Substitutions

Do not have lobster Use all shrimp or swap in chunks of crab meat Want an extra kick Try adding a pinch of cayenne to the cheese sauce No mozzarella Just add another cup of cheddar and bump up the parmesan half a cup

Serving Suggestions

This dish shines as a rich main course for dinner parties or holidays I love serving with a leafy green salad tossed in lemon vinaigrette The bright acidity balances the creamy cheese Bread is a must to soak up the sauce Garlic bread is fantastic if you are feeling indulgent

Use fresh sweet corn kernels in summer for added sweetness Swap parsley for chives in the spring for a milder herb flavor In cooler months add sautéed mushrooms to keep things cozy

04 8 ounces shrimp, peeled and deveined
05 1 cup cooked lobster meat, chopped

→ Cheese Sauce

06 3 tablespoons all-purpose flour
07 2 cups whole milk
08 1 cup heavy cream

12 1/2 teaspoon paprika

14 Fresh parsley, chopped, for garnish

Steps

Step 01

Bring a large pot of salted water to a rolling boil. Add elbow macaroni and cook until al dente, following package directions. Drain thoroughly and set aside.

Step 02

In a large skillet, heat butter and olive oil over medium-high heat. Sauté shrimp until opaque and pink, about 2 to 3 minutes. Add lobster meat, stirring just until heated through. Remove seafood from the skillet and set aside.

Step 03

In the same skillet or a medium saucepan, melt butter over medium heat. Whisk in flour and cook for 1 minute to form a roux. Gradually whisk in milk and heavy cream, stirring constantly until mixture thickens. Reduce heat to low, then blend in cheddar, mozzarella, and parmesan cheeses until smooth and melted. Season with paprika, salt, and black pepper.

Step 04

Gently fold cooked pasta along with the shrimp and lobster into the cheese sauce, ensuring even distribution. Transfer mixture to a greased 9 x 13-inch baking dish. Sprinkle with extra cheddar and mozzarella, if desired. Bake at 375°F for 20 to 25 minutes, or until golden and bubbling.

Step 05

Plate portions hot from the oven. Garnish with chopped fresh parsley and serve alongside warm Hawaiian rolls or brioche, if desired.

Notes

  1. For richest results, use freshly grated cheeses and avoid pre-shredded varieties which may contain anti-caking agents.
  2. Ensure all seafood is thoroughly dried before sautéing to avoid excess moisture.
