How to Make Lobster Mac and Cheese

Cook the Pasta

Cook cavatappi noodles according to package instructions. Drain and rinse with cold water to stop cooking, then set aside.

Make the Cheese Sauce

In a large pot over medium-high heat, melt the butter. Add garlic puree and stir to combine. Once melted, sprinkle in the flour and stir constantly until the flour starts to brown slightly, about 1–2 minutes.

Slowly pour in the milk while whisking continuously to avoid lumps. Add onion powder, salt, and pepper, and bring the mixture to a gentle boil, whisking until smooth and creamy.

Combine Pasta and Lobster

Add the cooked cavatappi noodles to the sauce, stirring until fully coated. Fold in the lobster chunks and chopped chives, cooking for about 3 minutes until heated through.

Add the Cheese

Lower the heat to low and add the shredded mozzarella, cheddar, and Swiss cheeses. Stir continuously until the cheeses melt completely and the sauce is smooth and creamy.

Serve

Serve hot, garnished with additional chives if desired, and enjoy a rich, cheesy, seafood-forward mac and cheese that’s sure to impress.

Tips for Success

• Use precooked lobster for convenience and quicker cooking
• Keep the heat moderate when melting the cheese to prevent separation
• Rinse pasta under cold water to stop overcooking before adding it to the sauce
