In a large pot of boiling salted water, cook 1 pound jumbo pasta shells according to package instructions. Shells should be fully cooked, not al dente. Drain pasta and rinse with cool water
Cupping a pasta shell in your palm, place about a tablespoon of the 2 cups pork carnitas into the shell. Wedge a 24 ounces cheddar cheese over the carnitas.
Wrap a second shell over the open side of stuffed shell to form a “lid.”
Spray the bottom of the air fryer basket with cooking spray
Set the stuffed shells in the basket of the air fryer, leaving just a bit of space between each shell.
Continue assembling the stuffed shells. Once the air fryer basket is filled, you canbegin cooking the batch.
Spray the tops and exposed sides of the stuffed shells in the basket. Set cook time for 13-15 minutes, at air fryer temperature of 400 degrees F.
Remove shells from the basket and keep warm while cooking the remaining batches.
While the shells are cooking in a small mixing bowl, mix together the 1 cup sour cream, and 1 tablespoon taco seasoning, mix well.
