Step 1

Heat a large skillet over medium-high heat. Cook and stir ground chicken in the hot skillet until browned and crumbly, 5 to 7 minutes; drain and discard grease.

Step 2

Melt butter in the skillet with the cooked chicken. Stir cayenne pepper sauce into the chicken mixture and remove from heat.

Step 3

Squeeze as much moisture from the ricotta cheese using a cheese cloth or paper towels; put drained cheese in a large bowl. Add chicken mixture to the cheese and stir. Refrigerate until completely chilled, 3 to 4 hours.

Step 4

Preheat oven to 375 degrees F (190 degrees C). Prepare a 13x9-inch baking dish with cooking spray.

Step 5

Bring a large pot of lightly salted water to a boil. Cook pasta shells in the boiling water until cooked through but firm to the bite, about 10 minutes; drain. Rinse with cold water until no longer hot; drain.

Step 6

Spoon chicken mixture into cooked pasta shells and arrange into the prepared baking dish. Sprinkle Cheddar-Monterey Jack cheese blend over the stuffed shells; season with salt and pepper.

Step 7

Bake in preheated oven until the cheese is slightly melted and the stuffing is hot in the middle, 15 to 20 minutes.
