Cajun Mac 'n Cheese

A beer cheddar bechamel loaded with sharp cheddar, shrimp, and andouille sausage, baked until bubbly — my homage to the best mac 'n cheese I've ever tasted on vacation.

On a family trip to Disney World, my mother-in-law came along so my husband and I could sneak off for a date night with my brother and sister-in-law. We ended up at The Boathouse in Disney Springs, and I showed up starving and ready to put a hurtin' on whatever came to the table.

My sister-in-law ordered the Cajun Mac 'n Cheese, and after just one bite off her plate, I completely lost interest in my own crabcakes. I picked at my food, waited for her to set down her fork, and the second she said she was done, I was already reaching for her plate. She rolled her eyes, smiled, and let me have it. She gets me.

I came home determined to recreate it — a beer cheddar bechamel loaded with so much sharp cheddar it should be illegal, packed with sauteed shrimp and andouille sausage, with just enough Cajun kick to keep things interesting.

Ingredients

  • 1/2 cup unsalted butter
  • 1/2 cup all-purpose flour
  • 6 oz. white ale beer (I typically use Blue Moon or something similar)
  • 2 tablespoons Cajun seasoning
  • 5 cups whole milk
  • 1/2 tablespoon kosher salt
  • 2 pounds grated sharp cheddar cheese (plus a little extra for sprinkling on top)
  • 1/2 pound fresh shrimp, peeled and de-veined
  • 1/2 pound andouille sausage, cut into 1/2 inch slices
  • 1 pound uncooked mezze penne pasta

Instructions

  1. 1Melt the butter in a pot over medium heat. Whisk in the flour and cook for 1 minute, then whisk in the beer, followed by the milk, Cajun seasoning, and salt.
  2. 2Continue cooking over medium heat, whisking occasionally to break up any clumps, while you cook the pasta according to package directions, pulling it a couple minutes short of done. Drain and rinse with cold water to stop the cooking.
  3. 3Saute the shrimp in 1/2 tablespoon butter over medium heat until opaque, about 3-4 minutes, then set aside.
  4. 4When the sauce has cooked for 12-15 minutes and thickened, reduce the heat to low and stir in the cheese with a large spoon (a whisk will make it clump). Stir until completely melted.
  5. 5Remove from heat and stir in the pasta, sausage, and shrimp. Pour into a 9x13 inch dish, sprinkle with extra cheese, and bake at 350 degrees for 25-30 minutes. Let rest 5 minutes before serving.

Storage & Reheating

This can be made 2-3 days ahead and reheated in a crock pot on low for 2-3 hours, stirring occasionally — great for a potluck. Freezer instructions: cool completely, cover, and refrigerate up to 5 days or freeze up to 3 months.
