Instructions
 

Prep

  • Preheat the oven to 400°F. Butter a 9-inch (approximately 1.5 L) round baking dish.

Cook the Pasta

  • Boil pasta in salted water until just al dente, see packet instructions. Drain and toss with 1 tablespoon butter.

Make the Cheese Sauce

  • Melt 2 tablespoon butter in a medium saucepan over medium heat.
  • Whisk in flour and cook 1 minute.
  • Slowly whisk in warm milk until smooth and thickened, about 3 to 4 minutes.
  • Stir in Dijon, Old Bay, garlic powder, and lemon zest.
  • Reduce heat to low and stir in cheddar, Havarti, and Parmesan until smooth.
  • Add lemon juice, dill, and celery. Season to taste.

Combine Pasta and Lobster

  • Fold the lobster meat into the creamy sauce, then stir in the pasta until evenly coated. Transfer to the prepared baking dish.

Make the Brioche Crumb

  • Toss brioche with melted butter, olive oil and Old Bay seasoning. Toast on a sheet pan at 400°F for 5 to 6 minutes. Scatter over the pasta.

Bake

  • Bake uncovered for 12 minutes until bubbling. Broil 1 to 2 minutes for extra colour.

Make the Lemon Dill Mayo Butter

  • Whisk melted butter (cooled slightly), mayo, lemon zest, lemon juice, dill, and salt.

Finish and Serve

  • Let the mac rest 2 to 3 minutes. Drizzle with lemon dill mayo butter and garnish with more dill or chives. Serve warm with lemon wedges, optional

Serving Suggestions

  • Serve directly from the baking dish for a cozy, shareable meal. Add a simple green salad with lemon vinaigrette to balance the richness. Pair with Chardonnay, sparkling wine, or iced tea.
