Three Cheese Lobster Mac and Cheese

I had lobster meat left over from our Christmas Eve lobster tail dinner and it turned into this delicious entree.  

Ingredients:

1 lb. bag of pasta tubes
3 tablespoons butter
3 tablespoons flour
2 cups milk
1/2 cup heavy cream
2 teaspoons Dijon mustard
1 cup shredded Gruyere/Swiss cheese (I found at Trader Joe's in a bag)
2 cups sharp cheddar cheese
Salt and pepper, to taste
The meat of 2 cooked lobster tails, chopped (leave bigger chunks, I cut mine too small the first time).  

Directions

Preheat oven to 350 degrees.
Bring a large pot of salted water to a boil.  Add pasta and cook according to package directions.  Drain in colander and return to stockpot.

Melt butter over medium heat in large saucepan.  Add flour and stir for 1 minute until combined.  Whisk in milk. Bring to a slight boil, whisking constantly.

Add cream, Dijon, cheeses, salt and pepper.  Remove pan from heat.  Stir together until all cheese is melted.  Add a small amount of additional milk if necessary to think it a bit.  

Mix in pasta and lobster.  Bake until golden, this will take about 20-25 minutes.
