Preheat the oven to 350 degrees. Spray a 9x13-inch baking dish with nonstick cooking spray.
In a large pot of salted, boiling water, cook the noodles until al dente, according to package directions. Drain.
While the pasta is cooking, in a large mixing bowl, combine the sour cream, cheese cubes, and salt and pepper. Stir in the drained noodles.
Spoon this mixture into the prepared baking dish. Bake for 15-20 minutes or until bubbly.
Notes
The dish may be frozen prior to baking. Simply chill completely in the fridge and store covered in the freezer. Thaw overnight in the refrigerator prior to baking.
