Step 1

Preheat the oven to 400 degrees F.

Step 2

Boil the lasagna noodles for 9 minutes in a pot of salted water. When cooked, drain and transfer to an ice bath for 1 minute. Lay out the noodles on a large cookie sheet and spray with cooking spray.

Step 3

In a 4-inch-deep full-size hotel pan, spread a layer of the barbecue sauce over the bottom. Arrange 5 slightly overlapping noodles to fully cover the bottom of the dish. Then spread a layer of pulled pork, followed by 5 ounces of the barbecue sauce and 1 quart of cheese. Continue layering with 5 more noodles, followed by a layer of smoked chicken, 5 ounces of barbecue sauce and 1 quart of cheese. Then create another layer with 5 more noodles, followed by a layer of Cajun sausage, 5 ounces of barbecue sauce and 1 quart of cheese. Finish with the remaining noodles, the rest of the barbecue sauce and the last quart of cheese.

Step 4

Bake, uncovered, until cooked through, about 30 minutes.
