Gluten Free Macaroni and Cheese

Yes, Yes, I'm still alive. It has been a trying couple of weeks. My car broke down and had to have the engine rebuilt and then my wife got strep throat. I figure I'm about a six pack of beer and a lost dog away from a good Country Western song. Here in the Portland area the weather can't seem to decide what to do. One day it's sunny and warm, the next it is cold, windy, and rainy. It's best just to whip up some comfort food and stick close to home this time of year. I don't usually get too crazy with macaroni and cheese. Simple is often best. However, I saw an episode of Barefoot Contessa where Ina made up some mac and cheese that looked delicious, bold, and easy. So, I had to give it a go.
Grown Up Macaroni and Cheese:
courtesy of Ina Garten, modified to be GF
4 ounces thick-sliced bacon
8-12 ounces GF elbow pasta (I use Ancient Harvest Quinoa)
1 1/2 cups milk
2 tablespoons unsalted butter
2 tablespoons GF flour mix
4 ounces Gruyere cheese, grated
3 ounces extra-sharp Cheddar, grated
2 ounces blue cheese, such as Roquefort, crumbled
1/4 teaspoon freshly ground black pepper
Pinch nutmeg
2 slices GF sandwich bread (I use Whole Foods Brand)
2 tablespoons freshly chopped basil leaves Cook the pasta per directions on the package. Drain well and set aside. Cook the bacon, coarsely chop and set aside.
In a medium sauce pan, melt butter and add the gf flour. Stir to combine. Whisk in the milk until it become smooth and coats the back of a spoon. Do not allow the milk to boil. Add all of the cheese and stir until smooth and creamy.
Add the chopped bacon, pepper, and nutmeg.
In a food processor, add the gf bread and basil. Pulse until combined into crumbs.
Mix the pasta and cheese sauce together. Pour into a 9x13 baking dish or several smaller baking dishes. Cover with bread crumb mixture. Bake at 400 degrees F for 10-15 minutes or until the bread topping is golden brown. Enjoy!!!
