First crisp the speck if you haven't already (or you can use prosciutto but I love the smoky flavor). Add speck slices to a cookie sheet and bake in the oven at 350 degrees F for about 10 minutes, until crisp. When done, remove and break into pieces. Set aside.
Next, boil salted water in a large pot for the pasta and cook macaroni until al-dente, about 8 minutes. Save about a cup of the pasta water and drain the pasta.
In the same pot, melt 5 Tb butter and 1/2 cup flour and whisk together until flour dissolves and gets thick, then add 1 cup milk and continue to whisk until thickened and add 1/2tsp cayenne, salt and pepper.
Mix in the shredded cheeses and add pasta and stir to combine. If too thick, add about 1/2-3/4 cup of reserved pasta water to the mixture.
Add to the best part! Add in the chopped lobster meat, fresh spinach and crisped speck peices. Stir everything together and taste for seasoning.
Grease a baking dish with 1 Tb butter all over and pour mac and cheese into baking dish. Top with panko breadcrumbs, freshly grated Parmesan cheese and drizzle of olive oil and bake at 350 degrees F for 12-15 minutes until top is golden brown.
Once done, allow to rest for at least 10 minutes.
