  • 1 Pound Cavatappi (or pasta of choice)
  • 14-16 ounces Lobster Meat – cooked and roughly chopped into large chunks
  • 1 Large Shallot – minced
  • 1 clove Garlic – minced
  • 5 TBS Unsalted Butter
  • 4 TBS All Purpose Flour
  • ¼ tsp Cayenne Pepper
  • ¾ tsp Mustard Powder
  • 1/8 tsp Nutmeg
  • 1 ½ Cups Whole Milk
  • 1 ½ Cups Heavy Cream
  • 1 Bay Leaf
  • 1 tsp Salt , plus more to taste
  • ¼ tsp Pepper , plus more to taste
  • 4 ounces Mascarpone Cheese
  • 1 ½ Cups Gruyere Cheese
  • 1 ½ Cups Fontina Cheese
  • Truffle Oil , to taste
  • Chives – thinly sliced, to taste
  1. Cook pasta according to package directions in heavily salted water, making sure to cook the noodles until al dente. Drain, reserving 1 ½ cups pasta water. Set aside
  2. Meanwhile, melt butter in a large saucepan over medium heat. Add the shallots and cool until translucent, about 3 minutes. Add in the garlic and cook until fragrant, an additional 30 seconds.
  3. Sprinkle the flour over the vegetables and whisk to coat. Add in the cayenne, mustard powder, nutmeg, salt and pepper. Cook, whisking constantly for 3 minutes.
  4. Add in the milk, heavy cream and bay leaf. Increase heat to medium high and bring to a gentle simmer, whisking frequently. Reduce heat to maintain simmer and cook until the sauce thickens, about 8-10 minutes, stirring occasionally. Remove bay leaf and discard.
  5. Reduce heat to low and stir in mascarpone until well incorporated. Add in the gruyere and fontina cheese, stir until melted. Stir in the pasta and ½ cup reserved pasta water. Gently fold in the lobster meat. Add more pasta water, ½ cup at a time if thinner consistency is desired. Taste and adjust for seasoning. Drizzle with Truffle oil or serve on the side. Enjoy!
